GN Company finished production of one set of Dewatering System, including Screw Press, Polymer Dosing Unit, and Sludge Feeding Pump (Progressive Cavity Pump) for Screw Press.

Dewatering Screw Press is used for sludge dewatering. Compared with Decanter Centrifuge or Filter Press, Screw Press has obvious advantages of low investment cost, low maintenance cost, and low power cost. It is a newly developed technology that dewatering is achieved by principle of screw extrusion, where strong squeezing force is generated by change of screw diameter and screw pitch, and tiny gap between floating ring and fixed ring.

GN Company now has developed different models of Screw Press with different capacities ranging from 0.1m3 per hour to 50m3 per hour, and discharged dry solids 5~640 kg per hour. And material of construction is available with ss304, ss316, and duplex stainless steel, such as 2205.

Polymer Dosing Unit can significantly increase performance of Screw Press, and Polymer Dosing Unit is used to gather fine solids particles to form bigger size solids. Dosing Capacity has 500L, 1000L, 2000L…5000L per hour.

Here you can find out two big advantages about GN Company, details as follow,

1. GN Company takes advantages of delivering One Stop Turnkey Solution.

Besides supplying single unit of Equipment, GN Company also manufacture accessories, including Pump, Screw Conveyor, Chemical Dosing Unit, Slurry Tank, etc.

2. GN Company can design and manufacture the whole system in Containerization or on Skid.

So it is safety and easier for transportation by truck, and movable around different job sites.

Welcome to visit GN factories, and check the actual production ability.

Recently GN Company completed production and final test of a batch of Vacuum Pumps for Steel Plant in India. GN Company is a professional manufacturer for Separation & Conveying Equipment, including Decanter Centrifuge (for sludge dewatering, liquid clarifying), Sludge Dewatering Screw Press (for sludge dewatering), Polymer Preparation Unit (for preparing chemical and dosing), and Sludge Solids Transfer Pump (for transferring high-solids/viscosity content sludge).

Sludge Vacuum Pump is pneumatic pump, which is 100% air driven/operation. The Pump can be used to transfer sludge, solids, slurry, and their mixtures.

Please find the Pump working video from linkage as below.

GN Company now has developed three 3 models, including 10B / 20B / 40B, with different capacities 10~40m3 per hour. The flow rate of Pump depends on Air Intake + Pump Volume.

For each specified model, its flow rate can be adjustable by setting time for both Suction / Discharge, which is 0~30 seconds.

Material for pump is made of carbon steel, which can reach mostly project requirement, while stainless 304 and 316 are all available.

The Pump is highly automatic working and much less maintenance and spare parts are always stocking in GN warehouse and can be posted anytime by Express.

GN Company has already supplied the Pump to Clients in UK, Norway, Russia, Portugal, Greece, UAE, Bahrain, Oman, India, Nigeria, Mongolia, Singapore, Malaysia, Canada, Mexico, etc.

It’s acceptable to arrange trial test with clients’ sample in GN factories, to check the Pump performance during actual operation.

Welcome to contact GN Sales Managers for details and more working videos about the Pump.

GN Company has completed final factory test and package of Sludge Dewatering Screw Press and Polymer Preparation Unit, and plan to ship by next week.

GN Company is a professional manufacturer of Separation and Conveying Equipment, including Decanter Centrifuge, Sludge Dewatering Screw Press, Polymer Dosing Unit, Sludge Feeding Pump (Progressive Cavity Pump), Tanks, and Accessories.

Sludge Dewatering Screw Press, it is economic and environmental friendly sludge dewatering equipment, which dewatering is achieved by screw extrusion, where strong squeezing force is generated by the change of screw diameter and screw pitch, and tiny gap between floating ring and fixed ring. It is completely different from Decanter Centrifuge, which dewatering is achieved by centrifugal force, to separate solids and liquid.

Sludge Dewatering Screw Press has obvious advantages of low investment and operation cost, and electricity cost.

GN Company now is capable to manufacture Screw Press with capacities ranging from 0.1m3/hour to 52m3/hour. Wetted touch parts can be made of stainless steel 304, 316, and duplex stainless steel is available, which is used for some clients’ project has high content of chloride. The motors and electrical control cabinet are all international reputable brand, which has advantages of long working hours, and reliable working performance, and clients can easily find spare parts in local country for maintenance.

Polymer Dosing Unit can greatly decide the performance of Screw Press. GN Company is capable to supply polymer preparation unit with capacities of 500, 1000, 2000, 3000, 4000, and 5000 per hour. And chemical of both powder and liquid are available. GN Company can also supply international reputable brand of Polymer Dosing Pump (Progressive Cavity Pump) and Polymer Metering Pump.

Welcome to contact GN Sales Managers, and they would offer detailed solution for your project.

GN Company is a professional manufacturer for Separation and Conveying Equipment, including Decanter Centrifuge, Industry Vibrating Screen, Disc Separator, Sludge Solids Vacuum Pump, Screw Conveyor, etc.

GN Oil Sludge Treatment System, which is used to recover clean oil and water separately from oil sludge, and make the sludge suitable to discharge to environment. This system includes Industry Vibrating Screen, 2-Phase Decanter Centrifuge, 3-Phase Disc Separator, Chemical Dosing Unit, and accessories, pipelines, etc. In order to get the best separation performance, the sludge would be treated step by step in different modules in the system.

Please find the video from linkage as below.

Here are the details explanations about the system.

Premixing Module, the sludge is always high density and viscosity, which is not easy to be pumped. And there are different sizes of particles in the sludge, which might damage the other equipment in the system, and seriously reduce their working life. So heating the sludge, and mixing with water to reduce solids content in the sludge, while adding chemicals into sludge, generally it is Demulsifier.

Separation Module, the sludge discharged from Premixing Module would be delivered to Separation Module for solids and two immiscible liquid’s separation.

Chemical Preparation and Dosing Module, it is used to prepare Flocculent and Demulsifier, which can significantly help to increase separation performance.

It is also acceptable to arrange trial test with clients’ sample in GN factories, and GN Technical Department would offer detailed experimental report after test.
