Membrane filtrationClean water is separated from the biomass by membrane filtration. The membrane is a physical barrier, securing treated water without micro-organism nor particulate matter. Pressure for the filtration is created either by a slight vacuum or by a gravity head. Some applicationsIndustries: Food and beverage, cosmetics, landfills leachate, manure processing, bio-fertilizer manufacturer, petro-chemical, mining and metallurgical industries, and hospital.Commercial buildings: Resort, casino, hotel, man-camp, rest area, mountain refuge, parks, office building, factory utilities, restaurant, shopping mall, airport, train station.Residential buildings: Small housing development, isolated community, apartment complex.Reuse treated wastewater and reduce by more than 50 % your water consumption.Some reuse applications:Cooling tower and system, toilet flushing, car, truck and tank washing, landscape and golf irrigation, ornamental, fire protection, dust control, non food crops irrigation.Very high performances, perfect for water reuseThe combination of ultra-filtration and high biomass concentration results in very high performances, complying towards numerous strict standards such as the US-EPA unrestricted urban reuse and non food crops irrigation reuse.Robust and ReliableEvac MBR is more resistant to shock load. The ultra-filtration provides an ultimate barrier against pathogens, such as the chlorine-resistant organisms, Cryptosporidium and Legionella.2*BDL Below detection limitsParameters Test Influent ConventionaltreatmentEvac MBREffluentEvac Removal Efficiency (%)TSS mg.L-1 1000 30 5 99.5BOD5 mgO2.L-1 500 30 5 99.0COD mgO2.L-1 1000 75 30 97.0TN mg.L-1 50 30 10 80TP mg.L-1 20 8 5 85Coliforms CFU.100mL-1 108- 109 104-105 BDL* 5 LogModelHydraulic loading, m3/dayDimensions**W x L x H, mmMBR 8 1.5 1480x3020x2440MBR 16 3 1560x3020x2440MBR 24 4.4 1960x3020x2440MBR 32 5.9 1960x3720w2440MBR 40 7.5 3775x1870x2430MBR 80 15 4590x2375x2430MBR 120 22.5 5090x2375x2430MBR 160 30 5260x2885x2430MBR 240 45 6255x2885x2430**The standard units without vacuum creation equipment are 470 mm shorter by lenght (MBR 8-24, 40-160)and 750 mm by lenght (MBR 32 and 240). Evac reserves rights for modifi cations.? The Refuge du Goûter is being built at 3,835 m on top of the Mont Blanc in France to welcome 120 persons a day and is following strict environmental quality standards, including Evac systems for water saving (vacuum toilet), and wastewater treatment and reuse for Zero Discharge.? The shopping center Wal?Mart located in Dalian, China, benefited from Evac products and expertise to meet the brand’s green goals. Evac provided a grease separator and a wastewater treatment for the restaurant kitchens allowing the reuse and saving of 45 m3/d for toilet flushing.? Robust and reliable? Small footprint?
