Because of complex component, high load of pollutant and large sewage capacity, the screening/bleaching effluent from paper mills has become the focus in pollution controlling.

Experimental study on straw pulp gray water treatment by ABR-SBR;

Tertiary decolorization treatment of pulp and paper effluent by using lignin-based flocculant

The influence of the parameters on the efficiency of pulp and paper effluent treatment by using the technology is discussed.

According to the physical characteristics and fluid properties of pulp and paper effluent, the problems that need to pay attention to in pressurized long pipe system design and installations and their solutions were discussed from some aspects of establishing simplified Bernoulli equation, preventing system pressure impulse and water beating generation.
