Multi Media Filter System with Anthracite and Quartz Sand for Industrial Water Treatment

A multi media filter system with anthracite & quartz sand DescriptionThis filter provides effective water treatment for removal of suspended solids, turbidity and fine particles from raw water and process waters in industrial applications.The multimedia filter is filled with two layers filtration media-anthracite(no- smoke coal) and quartz sand.Depth Filtration performance.Stable effluent.High operating cycle is obtained by using two layers of different kind of filtration media.It can be applied in HVAC filtration, industrial water treatment & pretreatment of high end treatment systems.

Filtration Media Structure

Filtration Rating is based on a simple yet extremely efficient two-media concept:

Top layer: Anthracite (No-Smoke Coal)

A light-density media which removes larger suspended particles and organic pollutants.

Bottom layer: Quartz Sand

A high density media for fine filtration and polishing.

This structure enables graded particle removal, improving overall filtration efficiency and reducing clogging risk.

Working Principle

Filtration principle:

The filtration system adopts depth filtration.

1.Rough water enters from the top of the filter tank.

2.The large particles in the water are filtered by the anthracite layer.

3.The water containing finer particles enters the quartz sand layer for filtration.

4.Treated water flows out from the outlet at the bottom of the filter tank.

5.The system automatically backwashes when the pressure loss increases to recover the filter capacity.

The anthracite layer combined with the quartz sand layer can ensure the filtration performance is not affected by high turbidity.

Key Components

The major components of a complete multi media filter system consist of the following:

1) Filter Vessel. Carbon steel or stainless steel tank manufactured to meet industrial pressure standards.

2) Dual Filter Media. Anthracite (top layer) & Quartz sand (bottom layer)

3) Internal Distribution System. System that allows even distribution of water through the filter bed.

4) Backwash System. Reverse water or air-water flow used to clean media of trapped solids.

5) Control System. Can be manual or automatic with pressure or timed backwash.

Advantages of Anthracite and Quartz Sand Filter System

High filtration efficiency

Removes suspended solids, turbidity and fine particles effectively.

Stable operation

Dual layer design allows stable filtration performance even with different water quality.

Long service cycle

Greater dirt holding capacity can lower backwash frequency.

Low operating cost

Simple structure with low maintenance and energy usage.

Strong adaptability

Can be applied for various raw water quality in industrial fields.

Conclusion

A multi media filter system using anthracite and quartz sand provides a reliable, cost-effective, and efficient solution for industrial water filtration. Its dual-media depth filtration design ensures stable water quality, improved system protection, and reduced maintenance costs.

It is an essential component in modern industrial water treatment and HVAC system optimization.
