Product Introduction

Multi media filter is a pressure type deep filtration equipment, which is filled with two or more filter materials such as quartz sand, anthracite, manganese sand, etc. in the tank, arranged in layers according to density, and uses the step-by-step interception effect of multi-layer filter materials to deeply purify the water body. The equipment can be backwashed automatically or manually, with a mature structure and stable operation, making it the most commonly used pre-treatment equipment in water treatment systems.

Technical Advantage

Stable filtration effect

Multi layer filter media intercept step by step, with a large interception capacity and low effluent turbidity, which can effectively protect subsequent precision equipment and membrane components.

Strong impact resistance

Strong adaptability to suspended solids and turbidity fluctuations, suitable for pre-treatment of raw water with large water quality fluctuations.

Economic and reliable operation

The equipment structure is simple, energy consumption is low, backwashing is thorough, the filter material can be reused for a long time, and maintenance costs are low.

Wide applicability

It can flexibly match filter media according to water quality and is suitable for various water sources such as groundwater, surface water, river water, and reclaimed water.
