Printing and dyeing wastewater mainly refers to the waste water comes from printing and dyeing mill, where process cotton, hemp, chemical fiber etc... Normally for this type wastewater capacity is huge. Generally 1 ton textile products will use 100-200 ton water, and normally 80-90% is wastewater. And printing and dyeing wastewater is one of the most difficult industrial wastewater, so normally in this industry, we recommend automatic membrane filter press.
While wastewater sludge dewatering, after pre-treatment and thickening, the wastewater will content around 2% solid. Then will be pumped into filter presses. Under pump pressure and squeezeing pressure of membrane filter plate, the final cake moisture will be around 60%. For the filter cakes, some mills will process in the incinerator.
In fact, normally we also regard laundry wastewater as same type, because content of lots fibers. And our belt filter press also is a good seller in the field. Pls contact us for membrane filter press price.
