The Ultimate FAQ for Industrial Sand Filter

Water treatment is presently the most sought-after remedy to water scarcity across the globe. With a myriad of technologies being presently exploited to alienate the stress on freshwater reservoirs, it is safe to conclude that water treatment holds the key to unlimited fresh water supply in the near future.

Sand filtration is a simple process exploited by industries to particularly eradicate suspended solids from water for improved quality. Underneath, we objectively discuss industrial sand filters and their involvement in water treatment.

➣What is a Sand Filter?

A sand filter is essentially a filtration media deployed in water treatment to eliminate suspended matter through mechanical encapsulation or absorption processes. Industrial sand filters are chiefly designed to eliminate relatively large suspended matter (approximately 50-100 microns).

Sand water filter systems typically operate via surface and depth filtration. Initially, surface filtration oversees the assemblage of elements on top of the filter bed resulting in a macro-porous lump that effectively traps other particles. In in-depth filtration, the finer particles attached to the sand particles are eliminated through adsorption.

➣How do Industrial Sand Filters Function?

Sand filtration is a broadly utilized technology in water treatment globally. As suggested by the name, industrial sand filters rely on the sand to filter water for distinct applications. For some industrial sand filters, pretreatment is enforced to guarantee the optimum removal of solid matter. Typically, flocculation, coagulation, and pH readjustment are the pretreatment technologies deployed in industrial sand filtration.

A sand filter bed, typically made of sand or gravel is responsible for capturing the objectionable particles. The feedwater is injected atop the sand filter and subsequently trickles down the filter bed (Surface or depth filters). Several processes are deployed to capture the particulates including:

• Diffusion.
• Direct collision.
• Surface charge attraction.

The sand granules deployed, often measure 0.35mm-1.2mm thereby facilitating effective filtration. After a while, the sand becomes overly polluted thereby prompting automatic backwashing. Essentially, the sand perforations increase in size allowing the captured particles to wash down consequently restoring their original state.

➣What are the Advantages of Industrial Sand Filters?

Simplicity and versatility are the primary pros of industrial sand filters. Thanks to their humble designs and impeccable filtration rates, they are utilized differently by varying industries.

Evidently, sand filters can be utilized as pretreatment mechanisms, side-stream filters, and post-treatment filters. Continuous industrial sand filters facilitate uninterrupted water treatment hence saving time and money. The following are additional benefits realized from the use of industrial sand filters.

• Considerably high removal of bacteria, viruses, and other illness-causing protozoans.
• Sufficient filtration rates.

➣What are Multimedia Sand Filters?

A multi-media sand filter is a multi-layered filter media (often 3 layers) deployed in industrial water treatment systems to eradicate finely sized suspended matter. Typically, a multimedia sand filter comprises:

●Anthracite.
●Gravel.
●Sand.

Multi-media filters utilize numerous filter mediums with varying densities for higher efficiencies. Multimedia sand filters support the filtration of finer particles and often eradicate up to 10-25 micron particles.

Characteristically, backwashing in multimedia sand filters sees the anthracite settle atop the filter while the garnet stratifies at the bottom. The sand settles in the mid-region hence allowing the capturing of large particles at the top and ultimately finer pollutants at the last layer.
