Energy Saving Filters for Wastewater Treatment Created

Science Daily, July 7, 2016, Nanyang Technological University.
https://www.sciencedaily.com/releases/2016/07/160707083312.htm

"Scientists have invented a new type of nanofilter that could reduce the energy needed to treat wastewater by up to five times. This breakthrough technology took about two years to develop and is now being commercialized across Asia."

"Water reuse is the practice of using treated wastewater in non-process applications as a method to conserve water. From automotive and aerospace technology to gas drilling and food and beverage manufacturing, many businesses have integrated water reuse practices into their production processes....  One of the most popular advanced treatment systems is a reverse osmosis program."

"On May 4, Clean Water Services, Energy Trust of Oregon and the Oregon Department of Energy formally announced the implementation of a new cogeneration system that converts wastewater and grease into renewable energy. The innovative system, which is part of Clean Water Services Durham Treatment Facility, is the third cogeneration system in Oregon to codigest fats, oils and grease (FOG)."

Sewage Treatment Plant Retrofits Diffusers to Cut Energy Consumption 50%

Blower & Vacuum Best Practices, Apr. 2016, by Doreen Tresca.

"VFDs [Variable Frequency Drives] can reduce energy consumption and water loss in variable pumping systems."

City Sewage Energy Recovery

North American Clean Energy, Jul/Aug 2015, by Erwin Schwartz B.Eng. is the President at DDI Heat Exchangers.
http://www.nacleanenergy.com/articles/20651/city-sewage-energy-recovery

"Municipal wastewater heat recovery is a system in which a heat exchanger transfers heat energy from the sewer waste water to a solution of water and antifreeze (ethylene glycol). A heat pump then uses the heat of this solution to heat buildings, preheat domestic hot water, and heat garages in the winter and also cool the space in the summer."


Biogas-To-Energy Helps A New York Facility Toward Self-Sufficiency

"Ithaca’s clean-water plant has boosted biogas production and energy generation in a project that will yield $9 million in guaranteed savings over a 20-year contract. The Ithaca (New York) Area Wastewater Treatment Facility now generates nearly half its electricity on site, and the plant team hopes a new biogas system can eventually meet most if not all power needs."
