Pressure sand Filters

Working Principle. Raw water is passed through the pressure sand filter, the filter media (Fine quartz sand) is supported on gravel pebbles bed of progressively larger sizes. During the filtration cycle the filter bed retains the dirt and suspended particles from the water and accumulates within the filter bed.

Reliability Matters

To extend the life of any seal, you want to control the fluid film that comes into contact with the seal face. This establishes the ideal lubrication, temperature, and pressure. A dual seal allows you to control of all these factors. Double seals require fluid exchange between the inboard and outboard seal faces.

Sand in Your Pool?

The same principle goes for washing out your sand filter. When a filter is backwashed, it is an absolute must that it be rinsed before returning to normal filtering mode. During backwashing the water's normal flow is reversed to flush out or loosen heavy dirt particles that clog the filter.

Rapid gravity sand filters: Developments in filter floor

The main components of a rapid gravity sand filter are the filter media, the gravel support layers and the filter underdrain. The underdrain serves to support the filter medium and gravel; to collect filtered water evenly from the bottom of the filter; and to distribute air and water evenly across the bottom of the filter during backwashing.

Multimedia Filtration

Flocculants / coagulants may be used upstream of the filter to induce the tiny dirt particles to join together to form particles large enough to be removed by the filter. This process is called "agglomeration" and, with proper chemical dosage, adequate mixing and adequate contact time, it will enable the filter to remove particles below 10 microns in average diameter.

Rapid sand filter

The rapid sand filter or rapid gravity filter is a type of filter used in water purification and is commonly used in municipal drinking water facilities as part of a multiple-stage treatment system.[1] Rapid sand filters were first developed in the 1890s, and improved designs were developed by the 1920s.[2] The first modern rapid sand

Duplex Filter, Duplex Basket Strainer Assembly

An ideal duplex filter working principle should allow for overhaul of filter media while running, and the duo filter element in the assembly provides redundancy. Also, the duplex filter element surface is critical in determining the differential pressure, hence, it is fitted with an electrical switch, which closes contacts to alert a lodged filter.

How Iron Filters Work

2011/2/9Once a filter is caked full of the sludge it removed from your water, it needs to completely clean itself out. A backwash is a forceful flush that removes this sludge. If a filter can't get clean, it will load up with crud and begin solidifying into a massive chunk that can weigh 100's to 1,000's of pounds.
