Pressure Sand Filter
Application
Sand filtration is one of the most effective means to remove suspended solids from water during water treatment. Our pressure sand filters optimize wastewater treatment, wastewater reuse, and water supply treatment operations. This process removes flocculated pollutants from water. The pollutants are retained during sedimentation and absorption, while the water is purified.
When the water contains suspended solids, mechanical impurities, and colloidal particles which cannot be removed by sedimentation, passing it through the filter layer in the pressure sand filter results in water that is clear and free from particles.
At the same time, pressure sand filter can also remove residual chlorine and color in water.

Design Details
Pressure sand filters use quartz sand as their filtration medium. This medium has high strength, long service life and large flow capacity. The quality of the effluent is reliable.
Sand filters are mainly used to remove suspended solids, colloids, sediment and rust from water.
Raw water is pumped through the filter medium which removes suspended solids with a high degree of effectiveness.
Features
(1) Simple in structure, easy to operate and can be automatically controlled to reach high efficiency;
(2) The resistance is small with a large processing flow. Few recoils happen.
Customizing Note
Please provide throughput and material requirements.
Huaneng Jinhao manufactures water treatment equipment and domestic sewage treatment plant to global markets, with decades of experience, we can fabricate any water treatment equipment and machinery like industrial water decanter, water filtration equipment, sludge separation equipment, and the auxiliaries of water treatment equipment.
