Pulp & Paper Waste Water Treatment Plants & Recycling Plants

The pulp and paper mill industry is an intensive consumer of water and natural resources (wood), discharging a variety of liquid, gaseous and solid wastes to the environment. Since the 1970s, a growing awareness of the effects of pulp and paper wastes in the ambience had prompted water and energy consumption levels and the loads of toxic compounds discharge to reduce. One of the most important implemented changes in this regard was made within the mill, wherein chlorine was completely substituted by, that is, chlorine dioxide as the bleaching chemical agent. Another major issue was the implementation of secondary biological treatments. The wastewater composition and hence the effluent treatment efficiencies and characteristics of the discharges are strongly dependent on the technology applied and the raw materials. In the last 25 years, however, the global distribution of pulp producers has significantly changed and so have the species of wood used. Eucalyptus pulp production, for example, is becoming a leader in the hardwood pulp market;

In the Pulp and Paper industry a lot of effort is used to water saving and closing water circuits, and to reduce substantially the environmental impact, by process modeling and Kidney technologies as internal process water treatment.

Effluents from pulp and paper mills contain solids and dissolved matter. Principal methods used to remove solids from pulp and paper mills effluents are screening, settling/clarification and flotation. The method chosen depends on the characteristics of the solid matter to be removed and the requirements placed on the purity of the treated water. The afore mentioned methods are used for the treatment of waste water from Pulp & Paper Plants. We as GLANCO RECOVERY & RECYCLE claim to recycle / recover waste water by means of using “state of the art” technology such as cross flow UF and cross flow RO / NF systems.
