Multi-media Filtration

Efficient Pretreatment | Stable Performance | Protect Downstream Equipment

The Multi-Media Filtration System is a high-efficiency pretreatment solution used in industrial and municipal water treatment. It uses multi-layer filter media such as quartz sand, anthracite, and garnet to remove suspended solids, turbidity, rust, and particulate impurities from raw water.

By significantly reducing turbidity and SDI, the system provides stable inlet water quality and effectively protects downstream equipment such as reverse osmosis (RO), ultrafiltration (UF), and softening systems.

Working principle

Raw water flows through graded multi-layer filter media from top to bottom. Larger particles are intercepted in the upper layers, while finer impurities are trapped in the lower layers, achieving deep filtration and high removal efficiency.
