Custom Engineered Treatment Systems

Waste water and sewage treatment with a membrane bioreactorYielding higher quality water with less sludge

BPW-MBR

Membrane Module

Treated effluent suitable for discharge to environment or reuse as process water or irrigation

Package plants/self-contained systems built and delivered

BI Pure Water (BPW) is now supply-ing packaged sewage and waste wa-ter treatment systems with flat sheet membrane modules or Membrane Bioreactors.

Manufactured in Germany, these ultra-filtration membranes have been tried and tested in thousands of applications worldwide. BI Pure Water uses the latest and best membrane technology which have a wide range of wastewater treatment applications.

Membrane Bioreactors combine con-ventional activated sludge treatment with membrane filtration, in a compact footprint, to produce high quality water as per Canadian and US discharge standards. The treated effluent can be reused as industrial process water and landscape irrigation.

BI Pure Water designs, builds, installs and services these custom engineered packaged waste water treatment systems.

Membrane bioreactors are custom designed and built in our Surrey facility, then delivered to your site in: • One 40-ft ISO shipping container for a

150-man (38 m3/d) 10,000 U.S. gal/d MBR for domestic sewage

• Multiple ISO shipping containers for larger flows and higher strength waste-waters

• Larger plants in 12’ wide x 12’ high x 40’ long steel tanks

• Concrete tanks for even higher flows

How It Works:Membrane modules are submerged directly into the wastewater and filtrate (filtered water) is drawn through and out of the membrane by a slight negative pressure. Solids, bacteria, parasites and viruses remain in the bioreactor to be digested by bacteria or settle as sludge. BPW-MBRs eliminate the need for the final stages of conventional wastewater treatment plants, including clarification and filtration.

Minimal Maintenance• With specially-designed air scouring, the

build-up of biofilms is greatly reduced and the need for chemical cleaning is once or twice per year. Membrane life is extended, minimizing maintenance.

• System layout is designed to accommo-date and simplify maintenance procedures

• Membranes are easy to load and remove for fast changeouts

Modular Scale-upBPW-MBR systems can be scaled up to 1 million gallons per day by simply using more membranes. Membranes are modular so that they can be arranged in various combinations inside the hous-ings – stacked or side-by-side – to reduce space. MBR uses much less space than conventional wastewater systems.

BPW-MBR System Advantages• Chemical-free self-cleaning with back-

pulse capability for reduced maintenance• Modular design minimizes space re-

quirements• Effective barrier against solids, organic

pollutants and micro-organisms• Consistent plate spacing for optimized

self-cleaning• Optimum design of scouring air diffus-

ers provides a 40% oxygen credit (re-duction in air requirement) for aeration tank for BPW-MBR as compared to other MBRs

• 60-80% less sludge produced versus conventional activated sludge systems
