Horizontal spiral centrifugal desilting machine for water treatment plant and sewage treatment plant

High moisture content of sludgeIt can reach 99% or even higher. It also includes plant nutrients such as heavy metals, organic matter, nitrogen and phosphorus, as well as toxic and harmful organic compounds. Sludge flocs are in a gelatinous state and are prone to decay, deterioration, and even epidemics, which can easily cause secondary pollution. Generally speaking, sludge can be classified into domestic sludge and industrial sludge based on the characteristics of the sewage source. There are four forms of water in sludge: interstitial water, capillary bound water, surface adsorbed water, and internal bound water.

The sludge dewatering process mainly consists of four parts: 1) sludge concentration, which involves preliminary dewatering of the sludge; 2) Sludge conditioning, changing the floc structure of sludge; 3) Sludge dewatering to reduce sludge volume; 4) Final disposal of sludge.

Zhejiang Chaoqian Environmental Protection Technology Co., Ltd. has precision production equipment and perfect production processes. Our company has passed ISO9001 quality management system certification, which is a solid-liquid separation equipment designed for customers! Our company has developed a series of solid-liquid separation equipment such as WL350/WL450/WL550/WL650/WL800, using international large cone angle and aspect ratio technology to separate solid phases with lower water content and clearer liquid phases! The company's equipment adopts dual motor frequency conversion equipment, which can not only protect the equipment from overload operation, but also enable the equipment to operate in a solid-liquid dehydration state. It can also achieve energy conservation, environmental protection, high work efficiency, and save unnecessary waste!

Large scale sewage treatment plants, especially municipal sewage treatment plants, are currently mostly in useHorizontal spiral sludge centrifugal dewatering machine for municipal wastewater treatment plantCompared to the belt filter press, the latter has the following advantages:

1. Large processing capacity (one 450 type ordinary horizontal screw machine has a processing capacity of 30 cubic meters per hour, but there are few machines)

2. Less environmental impact (closed treatment with a centrifuge and open treatment with a machine can easily cause secondary pollution)

3. Less use of polyacrylamide agents (for municipal sludge) (The principle of horizontal screw machine treatment relies on density difference separation, while belt machine requires larger floc aggregation and more obvious solid-liquid separation)

But there are also its drawbacks

1. It is relatively expensive (which is a major drawback);

2. Maintenance is troublesome and costly.

Domestic centrifuges have advantages in price and maintenance costs, but there is still a gap in equipment stability and processing capacity compared to several large centrifuge manufacturers abroad.

Horizontal spiral centrifugal desilting machine for water treatment plant and sewage treatment plantApplication fields:

The horizontal spiral discharge settling centrifuge is an efficient separation equipment that uses centrifugal settling suspension for continuous separation. It has high speed, strong separation ability, high production capacity, and low energy consumption. It can perform solid-liquid separation on various suspensions with significant differences in physical properties. It is mainly suitable for dewatering suspensions with solid concentration<35% and solid-liquid weight difference>0.05. This series of centrifuges has a wide range of applications and good adaptability to materials. It can be widely used in the concentration and dewatering of various sludge in municipal and industrial sewage treatment plants, as well as in various industrial separation fields, the extraction and production of various oils and fats, and various processes such as chemical, food, light industry, papermaking, mining, etc.
