  • Virginia Tech Invents Energy-Generating Ammonia Removal Technology
    Engineering com The technology according to Engineering com consists of a microbial electrochemical cell which allows bacteria to conduct electron shuttling chemical reactions while the forward osmosis cell uses a highly concentrated mixture to pull clean water through a membrane to remove impurities The microbial electrochemical cell which Qin has coined a bacterial battery harvests the microbial electrochemical reactions that naturally occur as the bacteria in the wastewater metabolizes This electricity drives ammonium ions present in the wastewater to the other side of the cell creating an ammonia rich solution according to Phys org Energy that is pulled from the cell can be stored or can be moved to the electrical grid The ammonia that is removed could potentially be sold for commercial use as ammonia based fertilizer providing a source of income for the wastewater treatment plant Additional processes will still be required to remove the ammonia from the nitrogen completely However this technology is an energy efficient way to both clean wastewater and produce ammonia from nitrogen gas a process that currently uses up 1 percent of the world s electricity By removing a significant portion of ammonia from the wastewater this technology may also play a role in protecting aquatic ecosystems from algae blooms We use so much energy to convert nitrogen gas into fertilizer and then in wastewater treatment we consume a lot of energy to convert ammonia into nitrogen gas said Jason He in an article for Phys org He an associate professor of civil and environmental engineering in the College of Engineering runs the lab where Qin created the technology A system that recovered the ammonia for later use instead of just removing it would be of great interest to sustainable wastewater treatment Quin received the 2015 Innovation Award for Best Technological Advancement from

  • The Secret To Savings Your Utility May Be Letting It Burn Away
    environmental impact projects were initiated to reduce the amount of methane gas burned off into the atmosphere It was then that city officials decided that instead of burning off the methane they would try and utilize it to power certain operations of the WWTP reports The Journal Gazette They began utilizing digesters which heat microscopic organisms and cause them to break down raw sewage in turn creating energy At our plant we have anaerobic digestion which produces methane gas said Doug Fasick a senior program manager for engineering at City Utilities according to the Gazette We re capturing that methane gas and running it through two generators that are 400 kilowatts each They re essentially supplementing our power needs for the water pollution control plant Methane is currently being used to supplements about 32 percent of the plant s energy needs Despite this success the utility has much bigger plans Its goal is to get the facility as close to off the grid as possible by supplying all its power in house On average electricity costs for the plant run about 1 3 million per year Together with the Three Rivers Filtration Plant which processes Fort Wayne s drinking water energy costs amount to about 2 million per year according to the Journal Gazette To generate enough methane to power all plant operations additional waste streams will be brought in and added to the anaerobic digester The utility is exploring the possibility of utilizing waste grease from commercial kitchens Currently that material typically comes in as part of the plant s normal wastewater treatment process which causes it to lose some of its energy potential This can be avoided by bringing grease directly to the digesters said Matthew Wirtz deputy director of City Utilities according to the Journal Gazette Right

  • New York City Strives For Net-Zero Energy At 14 WWTPs
    wastewater daily accounting for a large amount of energy consumption On New York s city government website the plan for achieving net zero in described in detail Improving the efficiency of wastewater treatment increasing the production of biogas and capturing and beneficially using all biogas as a renewable energy source will significantly reduce carbon emissions associated with flaring as well as offset emissions from energy generated from traditional fossil fuel sources Over the next decade the City will achieve further reductions in energy consumption across all of the wastewater treatment plants by decreasing demand increasing on site power generation recovering and reusing biogas and undertaking co digestion of organic wastes As part of this initiative the city recently announced a 30 million investment for upgrades of the Port Richmond Wastewater Treatment Plant on Staten Island The upgrades will include three new boilers a new exhaust capture system and one of the largest rooftop solar arrays in the city which will generate approximately 1 6 million kilowatt hours and will supply as much as 10 percent of the plant s power needs according to a press release released by the city All together the upgrades will reduce greenhouse gas emissions from plant operations by more than 28 000 metric tons The new boilers use a combination of biogas and natural gas and replace equipment dating to the 1970 s that ran on heating oil alone Using the byproducts of wastewater treatment to provide energy to fuel the same plant and shave off even more of the energy load with a sizable solar array makes a significant contribution to NYC s air quality as well as reduces energy and cost over the long run while bringing down greenhouse gas emissions said Nilda Mesa Director of the Mayor s Office of Sustainability according

  • Advanced Aeration In Hydraulic Fractured Water Impoundments
    interviews with three evaporation pit operators it was discovered that none deployed any scientific methodology to determine evaporation rate but all were convinced that their aeration methods helped Advanced Aeration Improves Evaporation There are multiple phenomena occurring when microbubbles and coarse bubbles are introduced in a subsurface fashion in a water impoundment First the rising bubbles cause surface disruption and may add momentum to the air increasing the rate at which the humid air is removed from the surface a critical aid to evaporation 2 Second when air is introduced into water bubbles are formed and diffusing vapor in the water migrates to the interior of the bubble 3 The resultant migrant vapor in the bubble reaches 100 percent relative humidity and is released during the breakup process at the surface 4 The combination of coarse and fine bubbles delivered from the water pit floor effectively destratifying the entire water column is considered advanced aeration As mentioned earlier a casual observation of existing fractured water impoundments notes some sort of surface aeration weeping systems periodic air jamming or other air sparging By field practice the operators realize the advantages of utilizing air in water management Score Card For Aeration Efficiency In 1984 the American Society of Civil Engineers ASCE adopted aeration efficiency standards The Standard Oxygen Transfer Efficiency SOTE test was developed to put all vendors methods on an even playing field The key to SOTE is evaluating the efficiency of introducing oxygen into a body of water The trial is recorded at sea level in clean water at 20 degrees C Bubble size is the single biggest factor to determine SOTE Fine bubbles 1 8 tend to rise more slowly providing better oxygen transfer efficiency Coarse bubbles 1 4 and often 1 to 2 are more effective at mixing Other factors in analyzing an aeration system are flow rate depth temperature elevation layout alpha and beta factors and maintenance Chart 1 shows the Standard Aeration Efficiency SAE for various aeration types at different water depths Keep in mind the higher SAE rating is the most desired as it takes into account implied utility costs The measurement is pounds of oxygen per horsepower per hour expressed as lb O2 hp hr Chart 1 Nature s Oxidant And Water Quality Improvements When advanced aeration is introduced to flowback water many water quality parameters begin improving in correlation to residence time or exposure Microbubbles can effectively introduce DO into the target water body Assuming anaerobic conditions a transformation from anaerobic DO 1 0 mg L to aerobic DO 1 0 mg L water occurs Sulfate reducing bacteria SRB are susceptible to the oxidation potential of DO 5 Initiating the oxidation of SRB inhibits the formation of hydrogen sulfide a colorless gas that is corrosive poisonous flammable and explosive Effective infusion of DO also begins the oxidation of hydrogen sulfide which helps mitigate multiple issues including odor 6 With increased DO the pH level in the water body begins to move toward stabilization
