Decanter centrifuge application in the paper industry

Sewage and sludge in the paper industry need to be treated in a sludge thickening tank. Now the main sludge treatment process is: pre-dehydration, dewatering of decanter centrifuge, crawler dehydration. After the sludge concentration is increased, the dewatering efficiency of the decanter centrifuge will increase accordingly. But it should be avoided that the sludge concentration becomes too high, which will cause the sludge transportation pipeline to block the concentration is too low.

The papermaking wastewater mainly comes from the two production processes of pulping and papermaking in the paper industry. Both processes discharge large amounts of wastewater. The wastewater from pulping is the most polluted. The waste water discharged during washing is black-brown, which is called black water. The concentration of pollutants in black water is very high, BOD is as high as 5-40g / L, and it contains a lot of fibers, inorganic salts and pigments.

The process of the decanter centrifuge to deal with the papermaking sewage is to make the sludge pass through the gravity dehydration zone, then to the pressure dehydration zone, and finally to the pressurized dehydration zone. After these three steps, a relatively dry mud cake is produced. The concentration suitable for dehydration is generally about 10%.

The decanter centrifuge has the advantages of low investment, automatic control, continuous operation, low energy consumption, high dehydration efficiency, easy management, low maintenance cost, low noise, and low dosage of chemical agents. Therefore, dewatering decanter centrifuges are recommended for papermaking wastewater and mud dewatering projects.

GN dewatering decanter centrifuge is E series decanter centrifuge with beach angle of 8.5 degrees. GN E series decanter centrifuge is usually used dewatering and thickening purpose. It is widely used for maximum dewatering requirements of municipal and industrial wastewater sludge. The dewatering decanter centrifuge is designed for easy separation material include large particle size, high density difference of solid and liquid, low viscosity, high concentration, high treatment capacity and higher dryness than clarity. The materials like sludge or wastewater containing fine particles usually need to be added with flocculants to gather the fine particles condensed into large ones, and then dewatered with E series decanter centrifuge.
