What is a quartz sand filter

Quartz sand filter, also known as shallow medium filter, is an efficient filtration equipment that uses quartz sand as the filtering medium. Its main purpose is to reduce water turbidity and purify water quality. The following is a detailed introduction about quartz sand filters:

1、 Working principle

The working principle of quartz sand filter is based on the filtering effect of quartz sand. Under a certain pressure, water with high turbidity is filtered through a certain thickness of granular or non granular quartz sand layer. When water flows through the quartz sand layer, a thin film is formed on its surface, which blocks and intercepts suspended solids, organic matter, colloidal particles, microorganisms, chlorine, odors, and some heavy metal ions in the water. Through this process, the turbidity of water is reduced and the water quality is purified.

2、 Main features

Efficient filtration: Quartz sand filters can effectively remove suspended solids, colloids, sediment, rust and other impurities from water, improving water quality.

Strong acid and alkali resistance: Quartz sand has good acid and alkali resistance and is suitable for various water quality conditions.

Good anti pollution performance: The quartz sand filter has a reasonable design, strong anti pollution ability, and can maintain stable filtration effect for a long time.

Adaptive operation: By optimizing the design of filter media and filters, quartz sand filters have achieved adaptive operation, with strong adaptability to raw water concentration, operating conditions, pretreatment processes, etc.

Backwash function: The system is equipped with complete protective devices and monitoring instruments, which have a backwash function and can quickly remove pollutants such as mud and dirt, with low water consumption.

3、 Application Fields

Quartz sand filters are widely used in the field of water treatment, including pre-treatment of pure water equipment and mineral water equipment, as well as deep treatment of sewage, sewage reuse, and water supply treatment. It is usually used as a pretreatment stage for reverse osmosis equipment, ultrafiltration equipment, and electrodialysis processes to ensure the water quality requirements for subsequent treatment processes.

4、 Usage and maintenance

Pre installation inspection: Before installing the quartz sand filter, carefully check whether there is any looseness in the connection parts to ensure that the equipment is stable and reliable.

Regular maintenance: According to the usage situation, regularly maintain and upkeep the quartz sand filter, including cleaning the filter material, checking the sealing of the equipment, etc.

Monitoring water quality: Real time monitoring of effluent water quality through monitoring instruments to ensure that the filtration effect meets the requirements.

In summary, quartz sand filters are efficient, stable, and durable water treatment equipment widely used in various water purification fields.
