A quartz sand filter is a pressure-type filter that uses refined quartz sand filter media filled inside the filter. When the incoming water flows downward through the filter layer, suspended solids and colloidal particles in the water are removed, thereby reducing the turbidity of the water.

  • Overview
    • Commodity name: Quartz sand filter

    A quartz sand filter is a pressure-type filter that uses refined quartz sand filter media filled inside the filter. When the incoming water flows downward through the filter layer, suspended solids and colloidal particles in the water are removed, thereby reducing the turbidity of the water.

    The Function of Quartz Sand Filtration

    A quartz sand filter is a pressure-type filter that uses refined quartz sand filter media filled inside the filter. When the incoming water flows downward through the filter layer, suspended solids and colloidal particles in the water are removed, thereby reducing the turbidity of the water.

    It is mainly used for pretreatment in water treatment processes such as turbidity removal, water softening, electrodialysis, and reverse osmosis (as a pre-treatment stage). It can also be applied to surface water, groundwater, and other water sources. Effectively, it removes suspended solids, organic matter, colloids, sediment, and similar impurities from water.

    Its applications are wide-ranging, covering industries and scenarios including:

    • Electronic power
    • Petrochemical industry
    • Metallurgy and electroplating
    • Papermaking and textile
    • Pharmaceutical dialysis
    • Food and beverage production
    • Domestic drinking water supply
    • Industrial water for factories and enterprises
    • Swimming pools

    It can meet the liquid filtration needs of various industries.

    Quartz sand filtration is one of the most effective methods for removing suspended solids from water, and it serves as a crucial unit in advanced sewage treatment, sewage reuse, and water supply treatment. Its function is to further remove flocculated pollutants in water; through the interception, sedimentation, and adsorption effects of the filter media, it achieves the goal of water purification.

    Scope of Application

    1. For industrial water, domestic water, and municipal water supply systems that require effluent turbidity ≤ 5mg/L (meeting drinking water quality standards);
    2. For the removal of suspended solids and solid substances in industrial sewage;
    3. Can be used as:
      • Pre-treatment equipment in ion exchange systems for water softening and desalination;
      • Rough filtration equipment for industrial water supply with low water quality requirements;
      • Equipment in swimming pool circulation treatment systems and cooling circulating water purification systems.
