30 m³/h Multi-Media Filter for Aquaculture Water Treatment

Product introduction of 30 m³/h Multi-Media Filter

The 30 m³/h multi-media filter is a pressure-type filtration system designed for solid-liquid separation in water treatment processes. It typically consists of a corrosion-resistant steel vessel filled with graded filter media such as anthracite, quartz sand, and gravel layers. The equipment is engineered to reduce suspended solids, colloids, and turbidity in raw water, making it suitable for pre-treatment and circulation systems. It is widely used in aquaculture, municipal water supply, and industrial process water systems where stable water quality is required. It helps operators meet strict water quality standards efficiently.

Working principle

The multi-media filter operates using pressure-driven downward flow through layered filter materials. Raw water enters the vessel and passes through anthracite, quartz sand, and supporting gravel layers. Suspended solids are captured by adsorption and mechanical interception as water moves through progressively finer media layers. Over time, accumulated impurities increase resistance, and the system initiates backwashing to restore filtration capacity. This cycle ensures continuous removal of turbidity and stable water quality output in various treatment applications.
