Flocculation for effluents going to drain
By flocculation, contaminants like media and metal fines, metal in solution and oil, are removed from the effluent. After flocculation, the water can be discharged to drain in full compliance with legal requirements.
Unfortunately, with this treatment method, the compound used in the finishing process is also lost and must be continuously replaced!
Crystal clear water
All effluents from mass finishing - also acidic or alkaline - can be transformed into clear water with a Trowalpur flocculation system. The clear water is in full compliance with legal requirements for discharge to drain.
Just disperse powder...
If the daily quantity of produced effluents is no larger than 3000 ltrs. it can easily be cleaned in an economical, easy to operate batch system of the type RT.
During the finishing operation, the effluent is collected in a collecting tank with stirrer, after which floculation powder is added. Within a short time, flocs are formed and sink to the bottom of the tank. They are automatically filtered during the night via filter bags or a filter press.
Automatic flocculation...
The fully automatic, PLC controlled Trowalpur GA and DO-systems have a capacity of up to 2000 litres per hour. They are used in larger mass finishing operations. The automatic Trowalpur flocculation systems have been in use for many years. They process batch by batch without the need for an operator. Many control functions guarantee a stable and safe effluent cleaning process.
Recycling?
Flocculation systems can also be used for process water recycling. Especially the semi-automatic RT... range which can easily be adapted for a recycling operation. The powder flocculant ESM is especially suitable for use in recycling operations.
Caution:
If parts tending to corrode are processed, reccling with flocculation systems is limited!
