As a sand filter collects more particles it becomes less efficient, collecting more and more dirt in the sand. It's time to backwash a sand filter when the pressure gauge on the filter reads 8-10 pounds higher than it did when the sand was new and clean.

H2K industrial sand filter systems are easy to operate and maintain, a pressure sensor, timer or manual initiation can be used to initiate the backwash cycle. Air Scour utilizes pressurized air for backwash assist of filter media layers of the vessel. Air scour before the backwash cycle breaks up the sediment from the filtering media allowing it to be backwashed out easily. Air scour is ...

A sand filter is basically a large tank filled with pool-grade sand, which is coarser than regular play sand. Water enters the tank through an inlet at the top, and gravity pulls it downward, removing impurities that get lodged in the sand. At the bottom of the tank, the water enters the laterals, which have tiny perforations that keep out the sand.

Backwashing water filters are large tank-style filters that get their name from the fact that they clean and renew themselves by backwashing. Backwashing consists of reversing the flow of water so that it enters from the bottom of the filter bed, lifts and rinses the bed, then exits through the top of the filter tank.

Slow sand filters work through the formation of a gelatinous layer (or biofilm) called the hypogeal layer or Schmutzdecke in the top few millimetres of the fine sand layer. The Schmutzdecke is formed in the first 10–20 days of operation and consists of bacteria, fungi, protozoa, rotifera and a range of aquatic insect larvae. As an epigeal biofilm ages, more algae tend to develop and larger ...

All sand filters use the same basic mechanics: when set to 'Filter', water flows from the pool, through the filter, and back into the pool. The sand inside the filter system blocks debris, dirt, and oil. A typical sand filter port system has 6 different settings – 'Filter', 'Backwash', 'Rinse', 'Circulate', 'Closed', and .

This means that the media can physically filter and trap the suspended solids in the water stream. Our backwashing filters have a dirt-carrying capacity that is three times the amount that a sand filter has. In addition, the granules can remove a wide range of colloidal and soluble inorganic metallic contaminants.

Sand filter systems operate most efficiently in the middle of the filtration cycle. This is partly due to the positioning, at any given time, of the sand in the filter, and, partly, because of the cyclical build-up of collected dirt and debris in the filter. The net effect is that too much, or too frequent, backwashing actually reduces the sand filter's efficiency. Finally, make sure you ...
