Backwash Water Savers | Filters
The backwash water system involves passing water through a bed of filter media contained in large tanks known as backwash filters. The Backwash Water Saver has been designed for use when there is a water shortage and water is not allowed to be wasted. The cartridge filter catches any dirt inside your sand filter that is flushed out during backwashing. The water which is normally wasted during the backwash process can then be redirected back into the pool, saving water.
The backwash water filtering system is highly effective in cleaning swimming pool water since it filters the dirt in water, and when used alongside other cleaning accessories can contribute to protecting your pool water against micro-organisms and bacteria, ensuring its cleanliness and safety. The name ‘backwash’ is derived from how the system works, as the water comes into the tank from the entry point, it should ideally pass through the granules which form the filter bed. However, the laws of physics dictate that liquids follow the route with the least resistance.
In the backwash system’s case, the water will tend to form channels around the debris in the tank to flow easily; this reduces the effectiveness of the filter bed. The system corrects this problem by flushing back the water through the outlet to resettle the debris which was initially displaced by the water coming from the inlet. The filter bed consists of sand, and tanks used in the backwash system contain valves that control the intervals so that the backwash happens at set times.
The time taken to filter water through the backwash water saver system depends on the size of the tank. Normally, larger tanks and light filters take a shorter time for water to go through the system. It’s however important to note that the less the time the water passes through the system, the less effective the filtering process.
