Filter presses vital in wastewater treatment

Filter press is crucial in sewage treatment, and its core function is to physically press to realize solid-liquid separation, reduce the concentration of pollutants, reduce the volume of sludge, and create conditions for subsequent water recovery or sludge disposal. The following multi-dimensional description of its importance: 

1.Efficient solid-liquid separation, reduce the concentration of pollutants. The core of sewage treatment is to remove pollutants in water, filter presses through high-pressure filtration media to intercept solid particles to form a cake, the filtrate into the subsequent treatment, significantly reducing the content of pollutants. Such as industrial wastewater and municipal sewage treatment, can effectively remove pollutants.

2.Reduce the volume of sludge, reduce disposal costs. Untreated sludge has a large volume, high water content, and high transportation and disposal costs. Filter press can reduce the water content of sludge, reduce the volume, and reduce the follow-up cost. Taking municipal sludge as an example, it can significantly save disposal costs.

3.Help water recycling. The filtrate separated by the filter press can be reused in water after further treatment for a variety of scenarios, improving the utilization rate of water resources and alleviating the shortage problem. In water-consuming industries, the reuse rate can reach more than 80%, reducing fresh water consumption.

4.Promote sludge resourceful disposal. The sludge after filter press can be utilized for resourcefulness and has various uses in agriculture, energy and building materials. The dewatering effect of filter press affects the feasibility and efficiency of sludge resource utilization.

5.Adapt to complex water quality, to ensure the stability of treatment. Compared with other dewatering equipment, the filter press is more adaptable to water quality, can deal with complex sewage, and the dewatering effect is stable, to ensure continuous operation of the sewage treatment system.

6.In line with environmental regulations, reduce environmental risks. With the strict environmental regulations, the filter press can ensure that the sewage is discharged according to standards, reduce fines and environmental liabilities, and the dewatered sludge can be easily disposed of in a compliant manner, reducing the risk of pollution.

In summary, the filter press is the key equipment to achieve “minimization, harmlessness, resource utilization” in sewage treatment, and is irreplaceable in many fields of sewage treatment.
