The RO Pretreatment Multi Media Filter is specially designed to improve the performance of reverse osmosis systems by reducing suspended solids and turbidity before membrane filtration. Stable pretreatment significantly decreases membrane fouling, extends membrane service life, and improves overall water treatment efficiency.
The Multi Media Filter is a highly efficient pressure filtration system designed for industrial and municipal water treatment applications. By utilizing multiple layers of filtration media with different particle sizes, the system effectively removes suspended solids, turbidity, sediment, and other impurities from water.
The filtration process is based on depth filtration technology, allowing larger particles to be retained in the upper media layer while finer particles are captured in the deeper layers. This structure significantly improves filtration efficiency, extends filtration cycles, and reduces maintenance frequency.
Equipped with automatic or manual backwashing functions, the system ensures stable operation, low pressure loss, and long service life under various water treatment conditions.
The Multi Media Filter is widely used as pretreatment equipment for reverse osmosis systems, cooling water systems, wastewater reuse, seawater desalination, and industrial process water treatment.
