2 Phase Wastewater Centrifuge 380/460V/600V For Grey Water Separation

2 Phase Separation Grey Water Centrifugal Wastewater Centrifuge

Grey water refers to integrated wastewater used in industrial production, such as chemical, power plants, hazardous waste high temperature treatment, printing and dyeing industries for dust removal, desulfurization, de-smoke, cooling, etc.

The significance of grey water treatment is:
1. After treatment, it can meet the standard of process reuse to achieve the goal of minimizing the production of sewage in the production.
2. Reduce the difficulty of the subsequent sewage treatment process and reduce the workload of sewage purification.

Take the gray water in hazardous waste high temperature treatment as an example:

The flue gas generated by the cinder after high-temperature gasification carries hazardous waste particles and dust, and the cooling water used for cooling in the process finally forms gray water. Today, with the growing demand for environmental protection and increasingly strict environmental protection policies, the handling of industrial hazardous waste has become a top priority.

Two-phase centrifuge model and technical parameters

The length dimension varies with motor power.

The orders of hazardous waste treatment plants are increasing day by day. With the expansion of their production capacity, the hazardous wastes of various industries are like a world apart. The composition of the gray water produced in the process of production varies greatly. In the traditional gray water treatment process, many hazardous waste treatment plants have selected vacuum belt filtration, plate and frame filter and other equipment for solid-liquid separation of gray water. Both of the above devices intercept the solid particles in the gray water through the filter medium.

However, the filtration effect of all the devices using the filter medium is limited by the size of the solid particles and the compressibility of the solid. The smaller the particle size, the less likely it is to capture, and the better the compressibility, the more easily the solid particles cause clogging of the filter screen, greatly reducing the filtration effect. As the composition of the gray water changes, the original effective filtration method gradually loses its due effect. The principle of the gray water treatment centrifuge developed by ZK separation is to use the density difference between the solid phase and the liquid phase in the water, and the high-speed rotation of the drum of the equipment produces a centrifuge that is thousands of times larger than the gravity of the object.

The solid and liquid in the water are stratified by centrifugation and then discharged separately through different liquid phase and solid phase outlets. This method is not limited by the gray water component, and adopts fully automatic control with variable frequency modulation to set different gray water for different industries. The parameters have a solid removal rate of over 98%.The equipment has small footprint, low energy consumption, fully automatic control, and can be easily operated by one person. The fully enclosed design makes it have excellent working environment, low noise, low vibration and low maintenance cost. It is widely used in power plants and chemical industry. Gray water treatment in factories, printing and dyeing plants, the effect is remarkable.

ZK separation design and manufacture special decanter centrifuge of industrial wastewater treatment has a unique setting and configuration for different industries and wastewater characteristics. This type of centrifuge is widely used in paper mill sewage, printing and dyeing plant sewage, coal washing water (commonly known as gray water), neutralization wastewater, power plant wastewater, purification water station wastewater, industrial cooling wastewater.

Featurers:

1. Water content in dewatered solids: 65%-81%

2. Solids content in liquid after separation: lower than 0.05~0.2%

3. Solids recycle rate: no less than 85%~98%

4. Chemical consumption per ton dry solids: 1~5kg/TDS

With the XBSY/WP decanter centrifuges, two liquids with different specific gravities can be individually separated from solids.

Solid-liquids are separated in the liquid phase zone and are decanted and discharged from the Solid bowl to prevent cross contamination. There is generally is discharged under pressure and which by big gravity . The adjustment during the operation of the centrifuge ensures maximum purity of both liquid phases, thus often removing the additional downstream separation machine.

Water Treatment field

The impurities such as glass and braids in the biochemical sludge from the sludge tank is pulverized and removed. The sludge pump sends the sludge (concentration 0.5~4% or higher) into the centrifuge, and the fully automatic flocculant dosing device adds continuously PAM flocculant solution (concentration 1~3‰) into the feed pipe through the dosing pump for flocculation in the feed pipe and in the vicinity to produce flocculus to be sent into the centrifuge. The dehydrated mud cake is discharged from the drum by a centrifuge, and transported to the outside through the screw conveyor.
