2021.09.23 Slurry Treatment System

GN design and manufacture slurry waste treatment or waste slurry management system. The slurry processing solution is to use liquid and solids separation equipment to treat soil or soup or slurry and produces reusable material for construction and discharge clean water. Normally, the slurry is contaminant-free comes from physical utility location in public right of ways, and directional drilling for placement of underground pipes or utilities or other private property construction.

As a leading manufacturer of separation equipment and conveying equipment, GN always pay high attention to the product quality and consider the long-term benefits for our users. We would also like to introduce GN as a professional manufacturer in decanter centrifuge field, GN pays a lot of attention in the selection of raw materials, high-quality centrifugal casting or forging stainless steel materials are used, and for wearing parts, hard alloy protection is used.

To make sure this set of Construction Slurry Dewatering Equipment will provide a reliable performance and the parts and components of all the equipment will run smoothly for a long term operation, our technical department, production department and quality control department have paid a lot of attention to the material selection, material preparation, every step of production and the inspection for this set of equipment in each step.

If you need any support about the operation and maintenance of GN’s equipment like Vibrating Screen, Shale Shaker, Desilter Cleaner, please feel free to contact GN company for our engineers’ best experience and knowledge in the relevant industry. We will do our best to assist your project because just in this way we can establish a stable and long term cooperation. And we can provide on-line support and site instruction for specific situation if needed.

Difference between solid-liquid & solid-liquid-liquid separation by decanter centrifuge

Difference between solid-liquid & solid-liquidliquid separation by decanter centrifuge

 

In the processing and selection of decanter centrifuge, it is sometimes necessary to judge whether solid-liquid two-phase separation can be completed in case of accident due to the difference of properties of materials to be separated, or whether liquid can be divided into light liquid and heavy liquid needs solid-liquid three-phase separation. This delineates the need for solid-liquid separation using two-phase separation or solid-liquid-liquid three-phase separation of decanter centrifuges.

two-phase-decanter-centrifuge

The two-phase decanter centrifuge consists of frame, cover, main bearing, drum, screw, differential, drive system and control system. The drum and the screw rotate at the same direction and high speed at different speeds. The material enters the inner cylinder of the screw through the feed pipe and enters the drum from the feed port.

Under the action of centrifugal force, the heavy solid-phase materials are deposited on the wall of the drum to form a sediment layer, and the spiral continuously pushes the deposited solid-phase materials to the cone end of the drum, which is discharged out of the machine through the slag discharge port. The lighter liquid phase materials form an inner liquid ring, which overflows the drum continuously from the overflow port at the big end of the drum, and is discharged out of the machine through the discharge port.

three-phase-decanter-centrifuge

The three-phase decanter centrifuge is mainly used for solid-liquid-liquid separation, that is, separation of one solid phase (high density) and two liquid phases with different densities. The drum and the screw rotate at the same direction and high speed at different speeds. The material enters the inner cylinder of the screw through the feed pipe and enters the drum from the feed port.

Under the action of centrifugal force, the solid phase material is deposited on the wall of the drum to form a sediment layer, and the two liquid phase materials form a light liquid phase ring and a heavy liquid phase ring respectively. From the wall of the drum, the solid phase layer, the heavy liquid phase layer and the light liquid phase layer are successively formed inward.

The solid materials deposited on the drum wall are continuously pushed to the cone end of the drum by the screw and discharged out of the machine through the slag discharge port. The light liquid phase and heavy liquid phase overflow continuously from different overflow ports at the big end of the drum, so as to realize three-phase separation.

Decanter centrifuge used for the sewage treatment

Clean water is becoming more and more valuable raw materials, which is why the importance of urban sewage treatment continues to grow. The sludge from drinking water and sewage treatment must be separated as effectively as possible. At present, the industrial decanter centrifuge is considered as the latest technology of sludge dewatering and thickening, which has the characteristics of economy, energy saving and high efficiency.

Desander Desilter

GN company has more than 12 years of experience in sewage sludge treatment. We understand the special requirements of sewage treatment plant and water industry. The GN Brand has been in the industry since 2007. GN products have been exported to over 70 countries in the world. Over 70% of the products are made for international customers. GN have branch in Houston, USA and Moscow, Russia for support to our local customer. GN make different types of decanter centrifuge include Clarifying Centrifuge, Classifying Centrifuge, Thickening Centrifuge, Dewatering Centrifuge.

Sludge decanter centrifuge specially developed for the special requirements of sewage treatment plant

The main purpose of dewatering process is to minimize the volume of sludge. The reason is that every tenth increase of dry solid in sludge will reduce the cost of sludge removal. A higher dry solid content was obtained.

It not only eases the subsequent treatment process, but also improves the overall performance of the sewage treatment plant. GN company is used to compact the sludge, so that the dry solid content of the sludge is concentrated in a few percentage points.

GN decanter centrifuge can also be used for the best mud thickening of polymer based strong flocking agent. The polymer is largely removable, and the horizontal decanter centrifuge can achieve very good value.

The sewage sludge can be produced in drinking water treatment. The decanter centrifuge is used to reduce the transportation and landfill cost of sludge, increase the dry solid content, and reduce the amount of polymer required.
