Sand Filter Wastewater Treatment

The characteristics of the mud produced in the water washing process of sand making plants, sand washing plants and gravel yards depend on its composition and are related to the local geological conditions. The general characteristics are that the mud is yellowish in appearance, uniform and viscous, and is left undisturbed for a long time. Floor. These muds come from building pilings, sand factories, mine tailings, tunnels and caves.

The characteristics of the mud produced in the water washing process of sand making plants, sand washing plants and gravel yards depend on its composition and are related to the local geological conditions. The general characteristics are that the mud is yellowish in appearance, uniform and viscous, and is left undisturbed for a long time. Floor. These muds come from building pilings, sand factories, mine tailings, tunnels and caves. The machine-made sand process is to crush pebbles or ore through a crusher, and wash the sand with sand washing equipment to obtain fine sand with less mud. This process produces a large amount of sewage. Among them, it is suspended in water, which is more difficult to settle, and direct discharge causes serious pollution to the water body and the environment.


2. Application of Sand filter wastewater treatment

An emery wear-resistant material manufacturer hopes to purchase a filter press equipment for the treatment of grinding wheel wastewater, improve resource utilization, and save energy and reduce emissions for the company. After understanding the specific situation of the customer, Su Dong gave suggestions for selection. The reinforced polypropylene membrane filter press is an ideal choice.

The relevant parameters in the test are as follows:


    Material to be treated: grinding wheel wastewater

    Material description: PH=3-4

    Select filter press model: reinforced polypropylene membrane filter press

    Feeding method: medium feed

    Filter cloth selection: polyester

    Filtration test situation: the filtrate is clear and the speed is fast

Application of Sand filter wastewater treatment 

After the solid-liquid separation treatment of the reinforced polypropylene membrane filter press, the water can be recycled, and the water content of the filter cake has reached the customer's requirements. It can be recycled for other purposes. Recycling and reuse will achieve good cost savings for customers .
