The Ultimate FAQ Guide to Quartz Sand Filters.

The meager reservoirs holding freshwater are continually depreciating thereby exposing more people and industries to water scarcity. Consequently, millions of people have been starved of options and therefore have to rely on polluted water, which exposes them to risks of contracting waterborne diseases.

Water filtration is one of the most widely sought-after remedies to water meagerness and water pollution. Beneath, we scrutinize a unique water filtration technology dependent on quartz sand filters and their distinct applications in water treatment.

➣What is a Quartz Sand Filter?

A quartz sand filter is a unique water filtration medium reliant on quartz sand to eliminate turbidity, organic elements, odor, and suspended solids at a specific pressure. Quartz sand is the filtration barrier that forms the core of the quartz sand filter. Typically, quartz sand filters are manufactured with varying sizes and can effectively treat water from distinct sources.

Additionally, the granules of quartz sand deployed as the filtration medium are adjustable in size with smaller diameters facilitating the removal of finer impurities. The deployment of quartz sand filters in water treatment can be supplemental or unaccompanied depending on the product water requirements.

➣What are the Advantages of Quartz Sand Filters?

Quartz sand filters are technically advanced water filters with unmatched effectiveness in eradicating suspended particles and water turbidity. They are also proficient at eliminating an array of impurities such as organic elements, chlorine, unpleasant odor, and microorganisms.

With the right customization, quartz sand filters can perfectly suit a range of applications including drinking water treatment and boiler feedwater generation. Water filtration using quartz sand filters is comparatively inexpensive and setting them up is pretty undemanding.

➣What are Quartz Sand Filters Made of?

At the core of a quartz sand filter is a colorless or white silicate mineral largely comprising SiO2 that acts as the filtration barrier. The quartz sand granules are intelligently distributed in a pressure vessel where they act as the primary filtration bed. The pressure vessel consists of elaborate service pipework, which facilitates the entry and emission of feed water, filtered water, and wastewater.

Pressure gauges to monitor the operating pressure and inform the user of excessive pressure drop or increment are also fitted onto the quartz sand filter. A control interface made of PLC is also a primary component of quartz sand filters. This allows for the automatic operation of the quartz sand filter.

➣What is the Working Principle of Quartz Sand Filters?

Quartz sand filters operate similarly to pressure sand filters with the distinguishing factor being the composition of the filter bed. Essentially, raw water is pumped into the vessel housing the quartz sand filter and steadily dispersed atop the quartz sand filter bed. Owing to gravity or external pressure, the inlet water progressively trickles down the filter bed.

As it trickles down, the suspended elements in the water are seized by the quartz sand granules through adsorption, diffusion, Van der Waals force, or direct diffusion. Consequently, the filtered water is harvested at the bottom of the pressure vessel. After continued filtration, backwashing is carried out to force out the amassed impurities. The following video breaks down the composition of a sand filter and expounds on its working principle.

➣Where is Quartz Sand Filter Mainly Used?

Owing to their impeccable effectiveness in eliminating turbidity and suspended constituents from water, quartz sand filters are highly coveted water treatment systems.
