MOBILE PASSIVE FLOCCULATION
WHAT IS PASSIVE WATER TREATMENT?
The chitosan technology is based on flocculation and sedimentation of particles and other particle-bound contaminants. IT was originally developed in Seattle, USA where it has proven to be a highly e ective method for water treatment.
Swedish Hydro Solutions AB has further developed the treatment method. This has resulted in lower costs, improved reliability and a system which is easier to operate and service. The system is patent pending and has not previously been available on the market. The system has been designed to meet the stringent treatment benchmarks from authorities and to be able to manage the high flows of stormwater that can occur during large construction and infrastructure projects.
The treatment chemistry is called chitosan, it is a completely biodegradable substance derived from crab shells. In the U.S the chitosan water treatment method has been named a “Best Management Practices” (BMP) for stormwater treatment. BMP’s are methods which have been approved by the state regulatory agencies to meet the federal water treatment legislation, the Clean Water Act.
The patent pending dosing system is installed in a mobile trailer. Incoming water is pumped to the dosing system where it comes in contact with the chitosan Biosocks and chitosan is dosed passively to the water. From the trailer the water is pumped to a sedimentation tank where the flocculated particles settle out and the water can be discharged to the environment..
The mobile system has a capacity to treat up to 1,000 liters per minute (60 m3/hour or 16 l/s). The system can easily be scaled up for higher flows if needed. The weight of a chitosan Biosock is 0,5 kg and it can treat up to 200 m3 of water, depending on the quality of incoming water.
