Why do we need to separate the solid and liquid from the sludge dewatering?
As a common pollutant, sludge can be seen everywhere in our daily work and life. We are accustomed to its existence, and even because plants are easy to grow on sludge, we like it.
But today we need to discuss the sludge generated in the Sewage Treatment process!
Why is it necessary to separate solid and liquid from sludge separator?
1. Improve treatment efficiency of sewage water filter
Reduce the volume of subsequent treatment:
The moisture content of sludge is usually as high as 95%~99% (such as residual activated sludge). After solid-Liquid Separation, the volume can be reduced by 50%~90%, which greatly reduces the load of subsequent treatment (such as digestion, dehydration, incineration).
Accelerate biochemical reaction:
In anaerobic digestion, concentrated sludge (solid content 5%~8%) degrades faster than unseparated sludge, and the methane production efficiency is increased by 20%~30%.
2. Reduce transportation and disposal costs of sewage water filter
After solid-liquid separation, the moisture content of sludge is greatly reduced, and the volume is also reduced by 50%~90%, reducing transportation costs, landfill costs or subsequent fermentation costs.
3. Meet environmental regulationsof sewage water filter
Most countries in the world have clear legal and regulatory requirements for sludge disposal. In order to meet these requirements and reduce environmental burden, solid-liquid separation of sludge is necessary.
4. Resource utilization premiseof sewage water filter
Energy recovery:
Dehydrated sludge (solid content 20%~30%) is more suitable for anaerobic digestion to produce biogas (1 ton of dry sludge ≈ 200~400 m³ biogas).
Land use:
Dehydrated sludge that meets the standards can be used as fertilizer or soil conditioner (heavy metals/pathogens must meet the standards).
Building materials:
Japan has a practice of making environmentally friendly cement from dehydrated sludge incineration ash, replacing 20%~30% of raw materials, which reduces the use of raw materials and reduces the environmental burden.
Avoid system blockage and corrosion of sewage water filter
During the sewage treatment process, if solid-liquid separation is not performed in advance, the sludge in the sewage will block the pipes, block the filtration system and corrode the equipment. It should be said that without solid-liquid separation, subsequent sewage treatment is out of the question.
The earth's environment is closely related to us humans. Since the industrial revolution, human impact on the earth has exceeded expectations. The melting of glaciers and rising sea levels are threatening the survival of humans in the future. Therefore, efficient and energy-saving environmental protection measures are of far-reaching significance.
