Industrial Sand Filters for Wastewater Treatment

● Quartz sand filter uses quartz sand as filler, which can be used to remove impurities in water, and is generally used as pretreatment for pure water equipment and mineral water equipment.
● Sand filter for water tank is one of the most effective means of removing suspended solids in water, and is an important unit in advanced sewage treatment, sewage reuse and water supply treatment.
● Its function is to further remove the pollutants that have been flocculated in the water. It achieves the purpose of water purification through the interception, sedimentation and adsorption of the filter material.

Product Process

●Water enters the fiter via the inlet and spreadsevenly onto the media.

●Solids and organic materials are trapped within the media.The clean water passes through the media and flows out via the nozzles.

●The back flushing process is done by shutting the inlet of the filter and allowing the water to enter from the bottom,lifting the media and releasing the solids that exit the filter through the back flush manifold This process can be controlled full automatically.

Industrial Sand Filters

Product Application

Industrial sand filter water treatment is suitable for drinking water filtration and other water purification treatment, and is more suitable for the pre-treatment and circulating water treatment of production water such as petroleum, chemical industry, mining, metallurgy, thermoelectricity, printing and dyeing, tanning, food, etc., as well as the recycling of sewage.

Product Advantages

● Compact structure: 

The sand filtration tank integrates coagulation reaction, filtration and continuous cleaning. The water treatment process is simplified, the floor space is small, the structure is simple, and the installation and operation are flexible and convenient. It reduces the energy consumption and labor management costs of multiple links in the raw water treatment process, and reduces the difficulty of operation.

● Easy to operate:

The auto backwash sand filter can be divided into manual type and fully automatic type. The manual type mainly controls the operation, forward washing, and backwashing of the filter through the adjustment of the valve; while the fully automatic type controls the operation, forward washing, and backwashing of the filter through the automatic head.

● Obvious effect:

The application of the coagulation reaction mechanism and the sedimentation mechanism can effectively remove the suspended solids and colloidal substances in the water, which is beneficial to further reduce the turbidity of the effluent in the sand filter area.

● Selected material:

The tank material can be divided into glass steel tank, carbon steel tank, stainless steel tank, and can also be made according to user requirements.

Great wealth roots in purification of sewage, which turns the Earth into a healthy planet.
