Flexo ink waste-water advanced treatment equipment CD-UF |
As a kind of new-type typical waste-water one in industrial printing & dying waste-water, water-based ink waste-water has several salient features: high CODcr, BOD, high chroma, and difficult bio-degradation.
Technological
process: This
sewage treatment recycling system removes the contaminants from water
effectively with a physical method to achieve the clarity of clear water. It
also neutralizes the acidity or alkalinity in sewage and removes hazardous
substances by precipitation and solid-waste separation. The clear solution in
waste-water is delivered by centrifugal pump to a precision filter and a carton
sand filter for filtration. At last, it passes the UF membrane and reverse
osmosis (RO) membrane, which can completely leach bacteria and tiny molecules
out with filtration micropore < 0.0001 μm, for filtration. Water through RO membrane filtration is recyclable RO pure water, which realizes zero emission and avoids secondary pollution during common environmental treatment.
