Biological Recycle Systems - BIO-25Series


The popular Mi-T-M BIO Series System utilizes fixed-film bacteria in conjunction with coalescing media to treat waste water. A variety of tank sizes and flow rates are used to create retention time to treat the wastewater. Oxygen is added to the bacteria in the waste stream by venturi injection system.

This system offers models available for either recycle or discharge operations. Each unit offers added benefits, such as:
· Low maintenance
· Low operating costs
· Simple equipment operation
· CSA approved control panel which meets the requirements of the US and Canadian standards for an Industrial Control Panel

The BIO Series is perfect for the following applications:
· Rental yards
· Heavy equipment dealers
· Trucking facilities
· Truck rental fleets
· Diesel repair facilities
· Forklift washing operations
· Aircraft maintenance and restoration
· Shipyards
· Municipalities/State DOTs
· Oil fields
· Engine rebuilders and manufacturers
· Military bases
· Golf courses
· and many more...

· CSA listed NEMA-4 rated corrosion-proof control panel for safe and reliable operation
· Hose connectors are clearly marked and designed for easy accessibility and quick installation
· Mazzei® venturi air injection system, 55-0126, sustains beneficial aerobic microbes while preventing bacteria from turning odorous and anaerobic
· Aeration pump, 3-0397
· Transfer pump, 3-0399
· Pressure manifold set-up option for BIO-20R-0M11 and BIO-20R-1M11 is standard
· Durable "True Union" valve

The Importance of a Proper Pit System:
Once equipment is washed, the untreated wash water flows into your pit system. A proper pit system for your application is the first step in proper wash water treatment and a critical element in any wash water recycle system.

Consult Mi-T-M Corporation or your local distributor to determine the pit system configuration that works best for your application.
