GN Company completed production of one set of Sludge Dewatering Screw Press, and planned to ship to the European client recently. The screw press would be used for sludge dewatering of municipal sewage.
Besides Decanter Centrifuge and Filter Press, Screw Press is newly developed equipment for sludge dewatering in wastewater treatment. And it has obvious advantages of low investment, low energy cost and low operation cost. It achieves dewatering function by principle of screw extrusion, through the strong squeezing force, which is generated from the change of screw diameter and screw pitch, and the tiny gap between floating ring and fixed ring.

GN Company now is capable to manufacture Screw Press with diameter 100mm, 130mm, 200mm … 400mm, with capacity ranging from 0.28m3 per hour to 130m3 per hour. The part contact with material is always made of stainless steel 304, 316, while duplex stainless steel 2205 can also be customized based on clients’ project requirement. For example, if the sludge has high content of Chloride, common ss304 or 316 cannot work well. The Motor for screw is reputable supplier from Japan, and the electrical components are from reputable European brands.

The Screw Press has self-cleaning function, and is not easy to get blockage, and has long service working hours.

Besides supplying dewatering equipment, GN Company is also capable to supply the other supporting equipment, including Sludge Feeding Pump (progressive cavity type), Polymer Preparation Unit with Dosing Pump, Screw Conveyor, Tank, etc.

Welcome to contact GN Sales Managers, and they would offer professional One Stop Turnkey Solution for clients’ projects.

GN Company’s Screw Press Received Great Attention among Clients

Screw Press Sludge Dewatering Machine is economical and environmentally friendly sludge dewatering equipment. It is a new type of solid liquid separation equipment, with applying the working principle of using screw extrusion, through strong extrusion force generated by the change of screw diameter and pitch, and the tiny gap between the moving ring and the fixed ring, the sludge can be squeezed and dewatered.

GN Screw Press consists of fully automatic control cabinet, flocculation modulation box, sludge thickening and dewatering host, and sump. The machine is equipped with automatic control technology, which can automatically realize flocculation, and continuously sludge thickening and squeezing dewatering work, and finally return or discharge the collected filtrate.

GN Screw Press Dewatering Machine can be widely used for sewage treatment in municipal, aquaculture, food, starch, oil, pharmaceutical, chemical, paper, leather and other industries.

Advantages about GN Screw Press as follow,
1. Wide application for different kinds of sludge dewatering, including oily sludge treatment.
2. Continuously automatically operation and not easy blockage.
3. Low investment and operating cost. And low maintenance cost, while there is no secondary pollution.
4. Energy saving and environmental protection, and small footprint.
5. Sludge can be dehydrated under aerobic conditions, which can avoid the release of phosphorus from anaerobic sludge dehydration.

GN Company now can manufacture and supply screw press with treatment capacity 0.14~52m3/hour (single unit), with DS production 5~640Kg/hour.
