  • The Call To Increase The Water Supply
    desire for prolonged world peace With the close knit relationship between invention and necessity in mind The United States Bureau of Reclamation USBR a branch of the Department of the Interior tasked with supervising water resource management has put out a call for research proposals that will increase the nation s usable water supply The request comes on behalf of the USBR s Desalination and Water Purification Research Program DWPR DWPR is accepting pitches for research and laboratory studies or full scale pilot projects It anticipates granting funds to between five and 15 studies at up to 150 000 each and between one and five pilot scale projects at 200 000 per year for each There are more stipulations attached including a fixed cost share provision and set funding durations The announcement came not coincidentally as the White House convened its Roundtable on Water Innovation led in part by Secretary of the Interior Sally Jewell The focus of that meeting was on developing clean water supplies in the face of the nation s drought with a particular emphasis on how private groups can and should contribute The goal of DWPR is to reduce the costs and environmental impacts of treating impaired and unusable water by funding research where the benefits are widespread and private sector entities are not able to make the full investments said Yuliana Porras Mendoza DWPR s program manager DWPR has supported over 150 such projects across the country which have received nearly 12 million from the government and required over 16 million in additional cost share funding The DWPR has been seeking proposals and funding research since 1998 Porras Mendoza said Some examples of innovation technologies that have been funded via DWPR include zero liquid discharge for concentrate management membrane bioreactors for wastewater treatment carbon nanotube

  • Dynamic Improvements In Low Pressure Membranes And System Design
    UF membrane dissected Low pressure membranes are available in a number of configurations including hollow fiber and flat sheet For hollow fiber there are two feedstream methods When the feed water is directed into the center channel of the fiber and the filtrate is recovered on the outside we call this an inside out process When the feed water is outside the fiber and is driven through to its center so that the filtrate is recovered on the inside we call this an outside in process The resulting flow path will dictate whether foulants build up on the inside or the outside of the hollow fiber Solids that are larger in diameter than the membrane pores are unable to pass through that barrier and will concentrate on the surface to form a filter cake As this layer accumulates the transmembrane pressure increases until it reaches a level that becomes prohibitive to operate A systematic backwash is initiated to loosen the foulants and remove them from the process The interim between backwash cycles varies depending on the amount of material in the feed the nature of the material being removed and the desired operational flux rate Systems operating at higher flux rates may require shorter times between backwashes since the material being removed will likely accumulate faster Some low pressure systems add an air scour process that helps dislodge more resistant filter cake materials and extends the time between backwashes The frequency and duration of air scour will vary from system to system with the goal of reducing it as much as possible as these methods require additional energy and necessitate a temporary shutdown of the applied system Air scouring in a submerged membrane system Several low pressure system manufactures have taken innovative approaches to minimize the need for backwash and air scour or help make these processes more effective One supplier incorporates a pulsed air method to eliminate the need for a continuous delivery of air and others have added microbubbles to improve the scouring effect Membrane bioreactors MBR pose a unique challenge Because these membranes are perpetually submerged in a highly concentrated solids bath the likelihood of solids accumulation at the surface is subsequently magnified In MBR systems backwash is not applied to dislodge solids but to use initiate a relaxation mode and impede the accumulated solids ability to inhibit flow Most systems employ continuous air scour to constantly dislodge solids and allow the system to effectively operate while others incorporate pulsed bursts of air to accomplish the same result MBR basin One manufacturer recently introduced a mechanism that gently and continually modulates the fiber bundles This no aeration MBR applies inertial force created by horizontal reciprocation of the submerged membranes to constantly dislodge particulates that would adhere to the membrane surface The continuous fiber movement during the back and forth rocking of the cassette is also said to prevent sludge accumulation Several pilot plants are currently in operation to qualify and document this method and verify the related

  • The Instrumentation Life-Cycle And Instrumentation Systems Within The UK Water Industry From Concept To Replacement
    what are you going to do with the data With this particular instrument the answer often will be To know what flow is being passed forward To monitor compliance To control flow to full treatment To control dosing rates for iron for phosphorus removal To control storm returns To control liquor returns All of the above or something else Generally instrumentation has a purpose over simple monitoring of what is happening and its use needs to be categorized into different tiers of use For example Tier 1 Simple state capture Any process in the water industry is an ever changing or unsteady state The instrument in Tier 1 use is simply there to capture and report on the state that the monitored process is in for the parameter or parameters that it is monitoring Tier 2 State capture and simple control In Tier 2 the instrument is there for some sort of control function either inputting into a wider control system or providing a simple control function For example a level controller on a pumping station Tier 3 State capture and advanced control In Tier 3 the instrument is there as part of an advanced control system It is inputting into a predictive model based control system as part of a feed forward control or providing an input into a feedback control system or some sort of cascade loop control system These tiers are arguable at best but they demonstrate that defining what an instrument is for will have a fundamental influence on the next steps within the process of the installation and operation of an instrument Instrumentation Selection Instrumentation selection is where the water industry often excels but the nuances of instrumentation selection are sometimes missed especially if an instrument s use has not been correctly defined The problem that the water industry has is this unless it is installed on a newly built asset the selection and subsequent installation is often a compromise As such the mode of operation is also a compromise and the instrument is not allowed to function as it necessarily should Instrumentation is often application specific and unless major and expensive modifications are made a compromise exists What this means in the current water industry is that supply chain application specialists from the different suppliers are often an absolute necessity in looking at specific applications for the different instrumentation types Cynicism will often exist insofar as engineers will often think that an instrument is being sold for the sake of getting a sale generally this is not the attitude that needs to be taken and better cooperation between engineer and application specialists are crucial to the correct installation selection Instrumentation Installation and Replacement The installation of instrumentation should be part and parcel to instrumentation selection and the role of the application specialist cannot be underestimated There are a number of questions to ask when installing an instrument within the water industry especially the wastewater side of the industry due to the hazards that are

  • How To Handle Faster Membrane Fouling
    water But the more a membrane is asked to do the faster it will become fouled As permeate flux increases so does membrane fouling by colloidal and particulate solids said Lee Durham technical support director for Avista Technologies We have seen increased fouling when permeate fluxes exceed industry established guidelines Boris Liberman the VP and CTO for membrane technologies at IDE Technologies estimates that higher mechanical durability and low transmembrane pressure allows membranes to handle eight times higher flow This in turn leads to eight times more fouling This can be solved in two ways explained Liberman Clean feed water eight times better which is extremely expensive or clean membranes eight times more frequently The practical way is to change the philosophy of membrane cleaning Liberman proposes putting aside chemical methods for membrane cleaning and embracing more ecologically friendly physical methods like frequent backwash and membrane micro oscillation While physical cleaning is commonly associated with taking the membrane offline in costly and time consuming fashion Liberman recommends an online osmotic backwash method which he claims would take about 10 seconds per day High flux operation unavoidably will request fast and frequent cleanings he said The membrane cleaning technology has to be developed in this corridor of fast online and environmentally friendly Durham for his part demurs In our experience proper in situ chemical cleaning is always more effective he said He warned against any method that involves removing elements from the system and disassembling them as unpractical Methods that involve micro bubbles or air water sparging also present problems in his view The introduction of air has the potential to reduce the cleaning efficacy by drying out the foulant and reducing the cleaning chemicals ability to penetrate the foulant and facilitate its removal from the membrane surface he said Durham

  • Source Water Protection There’s An App For That
    managing director of The Freshwater Trust Since then we ve continued to expand and adapt the platform to meet the needs of various projects and partners including time saving tools for characterizing streamside vegetation function for source water protection programs StreamBank Monitoring is a popular tool in the StreamBank toolkit It is a tablet optimized app for collecting project data in the field and compiling that data for analysis and reporting There are nine features in the app including vegetation monitoring riparian function assessments shade measurements photo point monitoring redds surveys and substrate monitoring The StreamBank Monitoring app is built on a monitoring protocol that is flexible enough to be used for various projects but also specific enough to be especially useful for vegetation monitoring said Sharon Gordon ecosystem services analyst for The Freshwater Trust This places the app squarely in between simple out of the box monitoring apps and custom made apps that aren t easily transferrable to other types of data collection A Look In The Toolbox The StreamBank Monitoring app is geared toward riparian vegetation actions It features a user interface designed to mimic workflow in the field and provide a visual record of tasks completed to help organize efforts on site and avoid data collection omissions The built in validation rules help ensure that data collection is complete and that values are within an expected range It s possible to carry forward relevant data from previous sampling events e g location latitude and longitude to maximize efficiency The menu selections significantly speed up data collection versus written notes which also improves data quality by helping ensure that all users are documenting site conditions in the same way and directing attention to all major factors such as browsing by wildlife that could damage plantings A quantitative vegetation monitoring feature is compatible with a wide variety of protocols and common metrics for example the app is flexible enough to allow the user to measure the amount of woody understory cover in terms of stem density cover or both On board tablet functions such as a camera are integrated into the app as a time saving measure to avoid carrying separate pieces of equipment into the field Rachel Werling an Oregon State University extension instructor has tested the StreamBank Monitoring app with high school students as part of the Student Watershed Assessment Team SWAT program which trains students to collect quality scientific data for natural resource management efforts in Jackson County OR Compared to traditional data entry methods with pen and paper the StreamBank app halved the time we spent collecting field data said Werling For example it was quick and easy to snap photo points to visually capture changes at a site using the camera on the tablet The app then recorded GPS location site name and other data along with the photo Without the app the students spent a lot more time transferring and processing data when we returned from the field Werling s time saving experience
