Sand Washing Wastewater Filter Press

In the production process of the construction industry, a large amount of sewage will be generated during the cleaning of placer, the overflow of mixing water in the production process of the mixing station, the cleaning of mixing equipment, and the cleaning of transportation equipment. Cement contains chemical components and alkalis that dissolve in the water. If it is discharged directly, it will penetrate into the ground and pollute the groundwater. If it flows into the river, it will pollute the water source and cause serious environmental pollution.

1. Harm of sand washing wastewater in concrete mixing plant

In the production process of the construction industry, a large amount of sewage will be generated during the cleaning of placer, the overflow of mixing water in the production process of the mixing station, the cleaning of mixing equipment, and the cleaning of transportation equipment. Cement contains chemical components and alkalis that dissolve in the water. If it is discharged directly, it will penetrate into the ground and pollute the groundwater. If it flows into the river, it will pollute the water source and cause serious environmental pollution. If it is filtered by a filter press, the water can be discharged to the mixing station for direct use , The filter cake after pressure filtration can be used to make bricks or paving roadbed materials to achieve the effect of waste utilization.


2. Application of Sand washing wastewater filter press

Construction industry wastewater contains a lot of hard sand and gravel particles. When the hard particles in the filter media contact the filter cloth, it is easy to cause damage to the filter cloth. Frequent replacement of the filter cloth brings a lot of operating costs. In this case, Sudong filter press recommends that customers choose composite rubber plate filter press and reinforced polypropylene plate filter press.

Application of Sand washing wastewater filter press 

The composite rubber filter plate can be formulated with different hardness according to the actual situation of the filter material. For example, the hardness of the sealing surface of the filter plate can be formulated to be able to adapt to the feed pressure of about 10 kg, and in this case, the material is not sprayed. The filter surface in contact with the filter cloth is more elastic. When the hard particles in the filter medium are in contact with the filter cloth, the filter cloth can be properly trapped in the rubber, and it will not form a hard filter plate. The filter surface and the hard particles in the filter medium will hardly hit the filter cloth. Compared with other filter presses, the damage rate of the filter cloth of the composite rubber filter plate filter press is reduced by more than 30%, thereby reducing operating costs.
