SLUDGE SCREW PRESS USED IN SOUTHEAST ASIA TEXTILE PLANT FOR WASTEWATER TREATMENT

Recently, GN sent a screw press to customer from Southeast Asia for wastewater treatment in textile plant. This equipment in this order is used as a trial unit to verify the applicability of the equipment. Therefore, the customer has chosen the smallest model in the GN product series. If the site operation is successful, the customer will order large model to meet industrial production.

The screw press is a compact sludge dewatering equipment, which is favored by many users because of its high degree of automation, low noise and low energy consumption. Generally, the screw press is structurally composed of two parts, the sludge flocculation bin and the dewatering assembly. The flocculation conditioning bin is used to receive the sludge to be treated and the chemical solution coming from polymer dosing unit. The sludge after flocculation naturally overflows to the dewatering assembly. After thickening and dewatering in the chamber composed of discs and screw, a relatively dry sludge cake is finally formed and discharged from the slag discharge port.

GN screw press machine uses SS304 as the shell of the equipment, the floating ring and the static ring, and the agitator in the flocculation bin. According to different properties of sludge to be treated, GN can also provide SS316 and duplex SS2205 with better corrosion resistance. In the control cabinet of GN screw press, the motor of the dewatering screw is equipped with a frequency converter, which can adjust the speed of the dewatering screw. If there is material blockage inside the screw, the screw can also be reversed to eliminate the material blockage.

Compared with the dewatering decanter centrifuge, the screw press has lower energy consumption and noise, and has better environmental friendliness in actual work; and compared with the filter press, the screw press has higher automatic working performance and operation convenience.
