Analysis of Resource Utilization of Sludge

KOSUN is a professional company that provides solid-liquid separation products and integrated solutions to solid waste disposal in the fields of energy conservation and environment protection, and focuses on development and services of complete technologies and equipment in sludge reduction, harmlessness and resource utilization. The sludge treated by KOSUN vertical centrifuge can be used as various resources in the following fields:

1. Agricultural resource utilization of sludge
If the sludge is used for agricultural purposes, it has the advantages of low operating cost, low energy consumption and low investment, and the organic part in sludge can be converted into the modifier component in the soil, so this utilization way is taken as the most promising disposal method.

2. Building materials utilization of sludge

2.1. Cementitious materials utilization of sludge
For sludge, it often contains more ash, especially in the treatment of sludge in wastewater by coagulation method, which contains a lot of Fe and Al components, and can be used as additives of building materials.

2.2. Sludge ceramsite
For lightweight ceramsite, it is usually used as a flower covering material or as a concrete aggregate and roadbed.

2.3. Sludge brick
Relevant researches show that sewer sludge can be used to make ecological bricks used in construction. This kind of brick is actually made by the following process: 10% sludge is mixed into the clay and then fired at 900°C, which can optimize the effect.

3. Animal feed utilization of sludge

Sludge contains lots of corresponding substances with many useful values, such as ash content ratio of 26.1% to 46.3%, fatty acids of 0 to 3.5%, and crude protein of 28.4% to 40.8%. Therefore, it can be treated as feed protein.

4. Sludge as fuel

The sludge itself is rich in organic matter. After low-temperature carbonization of sludge, the calorific value is equivalent to lignite, so the sludge can be used as fuel with a low calorific value.

If the sludge is not treated and is directly discharged into the environment, it will be seriously harmful to the surrounding environment. After the sludge is treated harmlessly, stabilized and reduced in volume, it can be used as a valuable resource in many fields.

Vertical Centrifuge Used in Hazardous Waste Disposal

Hazardous waste is a waste with properties that make it dangerous or capable of having a harmful effect on human health or the environment. So the units who produce hazardous wastes shall management them in accordance with the relevant provisions of the State. And the hazardous wastes are not allow to dump or stack. If they do not management the hazardous wastes, the administrative department of environmental protection of the local people’s government at or above the county level shall order them to make corrections within a prescribed time limit.The hazardous wastes disposal expenses shall be borne by the unit that produces the hazardous waste.

In September,2017,KOSUN vertical centrifuge(hazardous wastes disposal Equipment)has been sent to Xinjiang Karamay hazardous wastes disposal center for the reduction of hazardous waste Management.

In order to management hazardous waste economically,KOSUN supply vertical centrifuge to solve the problem.KOSUN vertical centrifuge reduces the pollution of the environment, in accordance with international emission standards and environmental protection requirements. With the continuous improvement of environmental protection requirements, the major fields are faced with the problem.

KOSUN vertical centrifuge(hazardous wastes disposal Equipment) is a vertical scraper discharge centrifuge, through the principle of centrifugal separation, the solid-liquid phase separated. Processing capacity can up to 40 to 60 tons per hour, the treated hazardous waste oil content is less than 5% (w / w), in line with international emission standards and environmental requirements, reducing the amount of waste disposal, thereby greatly reducing the hazardous wastes disposal costs.

The commonly used wear parts of vertical centrifuge can be replaced from the top of the unit; it is no need to move any device, you can also replace the belt; inner rotor scraper sprayed with tungsten carbide anti-corrosion wear-resistant materials can extend its service life and reduce maintenance Cost.KSOUN vertical centrifuge is the preferred equipment for hazardous wastes disposal!
