STEP-MBR from Enviro-STEP Technologies, sold here > Ontario


Enviro-STEP Technologies, Canadian distributor of unique gravity flux hollow plate membranes from Alfa Laval is proud to offer the STEP-MBR, the most simple and less mechanized MBR on the market.​

STEP-MBR combines extended aeration activated sludge process with liquid/solid separation using hollow plate membranes. Membrane plates are grouped in pre-assembled filtration modules (MFM) equipped with their aeration equipment assuring recirculation of mixed liquor and membrane scouring. Compared to conventional membranes requiring vacuum suction to pull treated effluent out of the membrane, the gravity flux membranes of the STEP-MBR only required about 450 mm of pressure head to generate high flux. This characteristic offers exceptional effluent quality and this without compromising on simplicity, ease of operation and ease of maintenance.​

STEP-MBR is offered either entirely pre-assembled or partially pre-assembled for retrofit. The plug and play version includes the biological reactor, aeration unit, membranes modules, backwash unit and control panel. Each of these ready to use units can handle 20 to 30 m³/d of domestic sewage. For higher flow, STEP-MBR is custom design to fit the application and site configuration.​

STEP-MBR can be configured to achieve BOD removal, nitrogen removal and phosphorus removal. When coagulant addition is provided, the phosphorus level can be as low as 0,1 mg/l. This make the STEP-MBR a preferred choice for sensitive area around lakes.​
