Bio-electrochemical Systems ( BES )
Forward Osmosis ( FO )
Nanoparticle Water Filtration System
N-E-W Tech
Organic matter in water is broken down into electrochemical cells through electrically active bacteria . This system is still in trial phase . In the FO process , water molecules from wastewater pass though FO membrane to other side with more concentrated solution . The process does not require energy input . Employing low-cost nanoparticle technology , a nano-silica-silver composite material is used for passive filtration , serving as an effective antifouling , antimicrobial , and chemical adsorptive material . The technology integrates hydrous ferric oxide reactive filtration in a moving bed sand filter , with added ozone and between 1 to 10 grams per gallon of functionalized biochar . The technology is still in a pilot trial phase .
Electrochemical cells produced in the process can be used to produce electricity , hydrogen and other high-value chemicals .
Concentrated waste can be processed to yield useful byproducts .
A passive process that does not need any chemicals , high-temperature , pressure , or electricity , it ’ s one of the most cost-effective treatment processes available .
Efficiently recovers nutrients from wastewater and removes antibioticresistant bacteria and antibiotic resistance genes .
Nanofiltration ( NF ) Hollow Fibre Membrane
Nereda
Hollow fibre membranes are used for water filtration , with the pressure required for effective filtration much lower than other systems . The technology is still in an initial commercialization phase . The Nereda process purifies water through the unique features of an aerobic granular biomass .
Does not require additional process such as ultrafiltration and reverse osmosis for complete treatment , resulting in overall treatment costs far lower than similar process .
Needs significantly lower initial investments , and saves around 25 to 35 percent in total energy costs .
