  • Super-Charged Wastewater Treatment And Energy Production
    business of water management and do not want to deploy precious capital and manpower for non core business processes will benefit from our technology By providing real time and remote monitoring clients can focus on what they do best rather than manage the ins and outs of water treatment This makes sustainability a real option where it may not have been viable before What are the main drivers for installing EcoVolt Breweries and wineries increasingly face soaring municipal wastewater treatment fees while water scarcity in California and elsewhere is driving up prices for fresh water We have seen these pressures force some of the most successful breweries to make costly decisions about how to maintain production Lagunitas Brewing Company for example could not dispose their water into their local sewer so instead they trucked wastewater to a larger neighboring water utility Our technology allows water intensive industries to continue operating with a distributed wastewater treatment system that saves water produces clean energy and slashes costs It s a compelling package for industrial companies How mature and tested is the technology Cambrian Innovation s technical team has been researching and developing bioelectrochemical technology behind Cambrian s product line since 2006 Cambrian received funding from NASA to develop a resource recovery technology for outer space and the DOD and EPA on self powered water treatment for off grid applications We have also won technology development grants from USDA the National Science Foundation NSF and others Justin Buck chief technology officer Cambrian Innovation The technology behind EcoVolt was conceived in 2009 and rapidly developed to a pilot demonstration by 2012 After two successful pilots the first for 15 months at Clos du Bois Winery and the second for eight months at Bear Republic Brewing Company Cambrian launched the product offering in 2013 and delivered our first commercial systems to both Bear Republic and Lagunitas Brewery in 2014 Today we work closely with partners to deliver systems seamlessly and on schedule What specific results were achieved for the existing installations The Lagunitas Brewery located in drought afflicted California can treat 60 000 gallons of water per day with the EcoVolt Reactor The system can generate 130 kilowatts of renewable electricity and 45 000 therms of heat per year Now with the addition of the EcoVolt MBR more than 40 percent of the site s current demand of clean water can be produced The brewery is cutting annual carbon emissions by 1 600 metric tons which is equivalent to planting 1 580 acres of forest every year Another way to think about the impact is by comparing the ratio of water to beer with our system against the ratio with business as usual Lagunitas is reducing their ratio from 4 1 to 2 5 1 How do you see the technology progressing We partner with our clients to collaborate on design and we re constantly looking for new ways to advance bioelectrochemical applications especially where the most devastating and urgent issues are being faced Following

  • Water Recycling Made Easy A Guide To Water Reuse For Food and Beverage Manufactures
    withdrawn There are many factors that may mean you ll end up having less water than you d like to have As water resources become more strained many food and beverage companies are turning to reuse to reduce the amount of water they require and the amount of wastewater they must dispose Obviously food and beverage production is very water intensive not only because of the water content in the product itself but because of the water needed to clean equipment and materials as well as the water needed for packaging and canning said Cotruvo A lot of companies are being squeezed because they need more water and they may not have access to more water So they must reuse and figuring out the most effective way to do that can be a challenge The water recovery and reuse guide created by the International Life Sciences Institute ILSI aims to make water reuse practices easier to implement for food and beverage manufactures The guide features information on how to conduct a water usage audit identify points where efficiencies can be increased select appropriate technologies conduct a hazard analysis of critical control points and develop implement or refine a water safety plan Not all water can be safely reused at a food or beverage manufacturing plant The guide does not include any information about how to reuse black water water that comes into contact with human waste For food and beverage water reuse practices there are two different ways of using recycled water outlined in the guideline high end use and low end use Recycled water used for high end processes like bottle washing or the washing of pipes or equipment must be handled differently than other types of water reuse because it indirectly comes into contact with a food or beverage product This recycled water must be disinfected to drinking water standards as defined by the World Health Organization using technologies like reverse osmosis RO membranes disinfection ozone and granular activated carbon explained Cotruvo Recycled water used for low end uses like washing trucks or skids outside is treated primarily for microbial quality requirements If you are using water in the plant anywhere near product it has to be drinking water quality said Cotruvo If you are using water to clean your skids and wash the trucks out in the shipping area that can be lower quality water The main issue there is to protect the workers you don t want them to be exposed to contaminated water You have to make sure the water is safe for human exposure Water Recycling Controversy While water reuse in the food and beverage industry is becoming increasingly more common industry giants like Coca Cola and PepsiCo are on board there is still a stigma associated with the practice A lot of people are queasy about the idea of water reuse anywhere near food said Cotruvo But the truth is with the right treatment methods the water is actually cleaner than it was

  • Revolutionary Sludge Management Comes To America
    easy to apply and better for the land Lystek International founded in 2000 is finally bringing the technology to the U S and what better place to start than in New York City Lystek in cooperation with Manhattan College is currently undertaking a confirmatory study for potential application at plants such as the Hunts Point Wastewater Treatment Plant WWTP to ensure the system s efficacy for the Big Apple s treatment requirements The company is also negotiating with municipal clients in California a massive agricultural market setting the stage for bicoastal adoption in two prime locations What s So Revolutionary According to Lystek s president Rick Mosher the system allows WWTPs to reduce sludge volumes by up to 30 percent increase biogas production by up to 40 percent and produce for potential sale a pathogen free nutrient rich fertilizer for farmers Marketed as LysteGro the fertilizer is unique due to its liquid form allowing it to be subsurface injected for even distribution and a 10 fold reduction in odor as compared to historical Class B application It s not as good as commercial fertilizer it s substantially better Mosher contended From a plant equipment and operations perspective the system is basically a severe pasteurization process that incorporates heat at 70 degrees C 158 degrees F alkali typically potassium hydroxide and high shear mixing to achieve hydrolysis or breakdown of the organics present in biosolids The resulting low viscosity liquid is not only available as a U S EPA Class A Exceptional Quality EQ and CFIA registered fertilizer for land application but can also be leveraged for plant optimization By adding pumps and piping WWTPs can recirculate the material to enhance microbial activity and performance in BNR tanks for denitrification and within anaerobic digesters for increased biogas production It s like enriched baby food for microorganisms said Kevin Litwiller Lystek s director of business development The system itself works at the back end of the treatment plant so regular treatment operations are not affected during construction or implementation O M requirements are very few once installed temperature and pH control along with change out of the mixing blades every six months or so The typical setup requires a modest footprint from as little as 1 000 to around 2 500 square feet according to Mosher and the reactors are also completely modular they can be sized for a treatment plant serving 15 000 people or for a city the size of say New York Send Me Your Sludge Back home in Dundalk Ontario Lystek has constructed a plant that treats biosolids and organics from a variety of customers throughout an 80 mile radius Nestled among farmlands the Organic Material Recovery Center converts up to 150 000 tons year and serves as a model for what Lystek envisions in California In addition to helping WWTPs Lystek s solutions can benefit industries such as food beverage agriculture of course and virtually any operation that produces organic waste There are 17 000 wastewater treatment

  • Feds Take Steps To Regulate Water For Food
    to water quality it s all about Agricultural Water Subpart E which essentially states that any water that will come in contact with fruits or vegetables also water used for handwashing during and after harvest must be regularly monitored Sources subject to monitoring include groundwater and surface water with different regulatory parameters for varying sources but not public water systems The rule affects growers and harvesters as well as anyone associated with the packing and holding of covered produce Therefore in addition to irrigation water the rule also applies to water used for washing cleaning cutting or slicing processes The FDA will require inspection maintenance monitoring and follow up actions related to these activities According to Frost Sullivan s MG water quality monitoring requirements will likely be handled through third party lab testing If a contaminant is found it is also incumbent upon the business to have a contingency plan in place to neutralize the contaminant s The comment period on the proposed rule had closed on March 15 2014 but the National Association of State Departments of Agriculture NASDA and other groups fought for an extension due to concerns over the burden of compliance for produce growers Compliance with water quality standards promulgated in the proposed rule will be the single greatest obstacle for fruit and vegetable producers regulated under the rule NASDA stated Many farms that use surface water indicate that the water quality requirements and testing intervals proposed in the rule will put farms out of business The expiration date on comments has been removed as decided by court settlement but Underwriters Laboratories Inc UL reports that a deadline of October 31 2015 has been installed for final rulemaking Once the final rule is effective 60 days after publication large businesses will have two years to comply Extremely small farms businesses with annual sales of less than 25 000 are exempt while FDA designated very small businesses average annual value of food sold 25 000 and 250 000 have four years to comply and small businesses average annual value of food sold 250 000 and 500 000 have three years The FDA states that qualified exemptions and modified requirements can also be granted Preventive Controls Rule The proposed rule on Preventive Controls for Human Food is less focused on water per se but is applicable to pumps and other water handling equipment used in food processing Businesses that manufacture process pack or hold human food are required to have a written food safety plan in place to prevent and resolve threats to food contamination The plan must address hazard analysis and prevention monitoring and recording procedures steps for corrective action and verification that the plan is being effectively followed One area of concern under the category of hazard prevention is the cleanliness of equipment that comes in contact with food including water used in food processing thus giving rise to the need for clean in place CIP stainless steel pumps Centrifugal PD pumps and gear pumps are

  • Wastewater Disinfection And Energy Generation Make ‘Hot’ Couple
    cost savings is achieved using a combination of renewable energy generation and wastewater disinfection technologies Biogas a natural byproduct of wastewater treatment or natural gas is used to drive a turbine that generates renewable energy This energy can be used to power multiple processes at a wastewater treatment plant and significantly offset the external electricity required However only 30 percent of the energy created by the turbine gets translated into electricity The rest leaves as exhaust waste heat With the PTG system that hot exhaust air is passed through a waste heat recovery unit and used to increases the temperature of the wastewater to around 165 degrees or higher the temperature needed to disinfect water The system solves two problems at once explained Ryan The energy guys are worried about energy costs and the disinfection guys are worried about disinfection byproducts he said Long term this is the solution to both The Water Environmental Federation WEF agreed awarding PTG with the Innovative Technology Award last October Heat has always been an effective way to disinfect water but the high expense of traditional heating methods prevented it from being an accepted alternative to UV or chorine We believe that heat is the best disinfection out there said Ryan UV and chlorine knock down live organisms to a certain level that is acceptable But heat is nondiscriminatory it kills everything even more than it needs to Our system is still going to be able to do an incredible job of disinfection PTG s technology has been certified by the State of California under Title 22 for the disinfection of wastewater for non potable reuse and safe discharge California s Title 22 is recognized globally as one of the toughest standards for water recycling and reuse Although the idea behind the PTG system is new the technology used is not The basics of the system include a turbine or engine a heat exchanger and a fan and pump to move the hot air This isn t scary new technology said Ryan We can take existing turbines and engines and design the system around that We don t have to build from scratch It is about combining three or four different pieces in a new or different manner The software incorporated into the system is a bit more high tech It allows the operators to remotely monitor the process from a tablet or smart phone giving them the ability to make adjustments from miles away If there is an issue you don t have to run out there you can pop open an app on an iPad and see how many gallons of water have been disinfected and make sure everything is running properly said Ryan There is very little maintenance required The PTG system has been on the market for approximately six months The technology was utilized as part of a three year test project at a municipal wastewater treatment plant in Ventura CA that disinfected 500 000 GPD gallons a day It

  • Microbe-Based Technology Treats Wastewater Generates Energy
    pollutants from wastewater and generate methane fuel that can be used on site for clean power and heat production These microbes generate electricity at a very high rate says Matt Silver Cambrian s CEO and co founder We are very excited to be the first to bring this to the market EcoVolt Bioelectric Treatment System from Cambrian Innovation on Vimeo The system is applicable to a variety of sectors that deal with wastewater treatment but Cambrian is currently marketing the EcoVolt to the food and beverage industry This is due to the high level of biochemical oxygen demand BOD in the wastewater streams at food and beverage facilities We can treat BOD concentrations that are below what the average system is able to treat Silver says Wineries and breweries are in need of energy efficient water treatment equipment On average a winery uses five to seven gallons of water to produce one gallon of wine A brewery uses an estimated six gallons of water to produce one gallon of beer Dealing with this much wastewater requires a large amount of energy Drinking water and wastewater systems account for approximately 3 to 4 percent of energy use in the United States resulting in emissions of more than 45 million tons of greenhouse gases annually according to the EPA Although the EcoVolt system does require some energy to get started the energy it creates allows facilities to save money decrease grid reliance and move toward a sustainable water management plan When you think about competing water treatment methods their electricity consumption is massive says Silver This is a water treatment system that has a positive energy effect The EcoVolt has other benefits as well The system is designed so the operators can focus on day to day business operations instead of wastewater

  • A New Approach To Early Biofilm Detection
    occurs when communities of microorganisms attach to a surface can deteriorate structures and products and cause potentially harmful biological contaminations Where water is used as an element of industrial processes bacterial biofilms appear sooner or later says Pavanello It is well known that biofilms represent an extremely hospitable environment for pathogens even when they are not involved directly in its formation But detecting this predator can be tricky requiring expensive time consuming laboratory analysis that isn t always representative of real world conditions To assist industrial operators in managing and preventing biofilm Italian start up ALVIM Srl created a monitoring system that provides early warning detection of bacterial biofilm growing on pipelines tanks heat exchangers RO membranes and other equipment The new ALVIM monitoring system developed by Italian private companies in collaboration with ISMAR CNR detects bacterial settlements in real time Based on that data the system manually or automatically adjusts and optimizes biofilm prevention and water cleaning treatments The biofilm monitoring system is the flagship product of ALVIM which was named the number one most compelling company for the first quarter of 2013 by independent research and advisory firm Lux Research Lux predicted that ALVIM s biofilm monitoring system would see rapid adoption by industries that have previously counted on indirect measures of safety An accurate monitoring system is critical for power plants refineries food and beverage production plants desalination facilities paper mills and other sectors that deal with biofilm says Pavanello who serves as director of ALVIM This is because biocides the chemical substances used to prevent biofilm can negatively affect the environment after the compounds are discharged from the treatment process into rivers and lakes Biocides kill bacteria or inhibit their growth In addition overuse of biocides can cause unnecessary expense Pavanello says In most cases biocides
