At the origins of BIOSEPTM Pack 3Twenty years ago, BIOSEP™, the first VWS membrane bioreactor, revolutionized treatment of concentrated industrial effluents. Since that time, this technology, recognized for its efficiency and compactness, has been fitted to about hundred water treatment plants throughout the world.

In the mean time, its applications have been extended to other effluents, especially municipal, and the solutions provided were standardized in the form of the BIOSEP™ Pack. With all the confidence given by its success over the last 10 years, VWS has widened its range and now proposes its optimized version, BIOSEP™ Pack 3, a concentration of innovations designed to meet users’ new requirements using best alternatives.

Service included, thanks to BIOSEP™ CareThis technical assistance contract helps for operation and long term performance of the system. Our technicians come directly on site for :

• corrective and preventive maintenance,

• assistance for membrane follow up,

• reagent dosing

• and any process support required.

Service • Integration of customer constraints (new or existing plants) • Pre-commissioning for a simple and rapid start-up • Ergonomic modular design • Technical assistance with BIOSEP™ Care

Responsibility• Low water and carbon footprint• Easy operation in complete safety • Time saving to focus on core activities

Value • High water quality available for recycling• Extra free space due to the system’s compactness • Longer service life for a more resistant system • Operation and maintenance cost is largely reduced

Produce high quality water from wastewater effluentsBIOSEP Pack 3 eliminates carbonated, nitrogenous and phosphorous pollution, retains total suspended solids and disinfects the effluent to make it available for recycling (irrigation, cleaning, …).To either improve the capacity, enhance treatment performances or equip a new installation, the BIOSEP Pack 3 is an ideal tool for:

Municipal wastewater treatment plants from 800 to 10 000 P.E

Industries wishing to treat their effluents while managing their energy and water consumption.

This unit uses four times less space than a classic biological installation and reaches higher performances even for highly concentrated wastewater.

• Large flow range available depending on wastewater type

• The installation timing is minimized

• The “Start & Stop” aeration system only airs out the membranes during the water production phase.

• High resistance to load variations

• Gain in space and flexibility: Compact, flexible, modular and easy to dismantle

• Compliance with standards under all circumstances

• Easy adaption to client needs (tank level, local manufacturing)

• Simplicity, comfort and long service life: use of highly resistant materials (PVDF membranes and GRP tank), fully automated system and safer operation

• Operational saving- Energy reduction: The gravity filtration of permeate

replaces the usual electric pump for MBR- Water saving: No daily backwash, effluent quality

suitable for recycling ad producing process water with additional reverse osmosis.

Immersed in sludge inside a tank, the membrane fibers separate activated sludge and treated water by sucking it from the exterior to the interior. To avoid sludge accumulation on the surface, the fibers are scoured with pressurized air and filtration is alternating with relaxation phases. This process limits energy consumption and loss of treated water. Only an automatic chemical backwash is performed once a week to optimize membrane lifespan.

BIOSEPTM Pack 3 is added to a biological aeration tank. The membrane bioreactor replaces the traditional settling system and separates perfectly the purifying biomass from the treated effluent through microfiltration. With a cut-off level of 0.4 μm, the micro-filtered water is of excellent bacteriological quality and removal of TSS is guaranteed at any time.
