Customizability Water Treatment System - Shallow Sand Filter
1 . Descriptions:
The shallow media filter uses natural sea sand as a filtration medium. Under a certain pressure, water turbidity is reduced through a specific thickness of granular or non-granular natural sea sand, effectively retaining and removing suspended solids, organic matter, colloidal particles, microorganisms, chlorine, odors, and some heavy metal ions. This results in a highly efficient purification effect, making it ideal for both wastewater treatment systems and pure water treatment systems.
The fully automatic shallow sand filter features a spherical shell and a unique internal structure design, ensuring smooth water flow during filtration and excellent filtration performance. The backwashing process creates countless internal circulations, enhancing the backwashing effect. Compared to traditional sand filters, it has advantages such as using less sand and consuming less water, making it a valuable addition to both wastewater treatment systems and pure water treatment systems, optimizing overall efficiency and effectiveness.

3 . Specificities:
1. All ports are designed to be completely leak-proof, and the system applies the principle of water pressure closure, which is safe and reliable.
2. High filtration flow rate, high efficiency, in the backwash state, the formation of the inner loop flow does not run sand.
3. The filter shell is composed of stainless steel, steel lined with rubber or full plastic, with high pressure-to-weight ratio and corrosion resistance.
4. Relying on independent multifunctional valve to control the backwashing of the system, low management cost.
4 . Appliance:
1. Agricultural irrigation: shallow sand filters are used in agricultural irrigation systems to remove suspended solids, sediment and particles in irrigation water, prevent the clogging of drip and sprinkler irrigation equipment, and ensure the normal operation of the irrigation system.
2. industrial water treatment: in industrial cooling systems, shallow sand filters are used to filter cooling water, remove suspended solids and particles in the water, prevent clogging and scaling of cooling equipment and pipelines, and improve cooling efficiency and equipment life.
3. Sewage treatment: in municipal sewage treatment plants, shallow sand filters are used for secondary and tertiary treatment of sewage to remove suspended solids and organic matter in sewage, improve the quality of effluent water and protect the environment.
4. Rainwater collection and utilization: in the rainwater collection system, shallow sand filter is used to filter the collected rainwater, remove the sediment and suspended matter in the rainwater, and improve the utilization rate of rainwater.
