Sand Filter

Sand Filter

Sand filter is a device used to remove impurities and suspended particles from water. It works by passing water through a layer of sand, which retains the larger particles. Clean water then flows to the outlet side of the filter. Sand filters are commonly used in water treatment systems such as swimming pools, water supply systems and industries.

working process

The process of operating a sand filter is relatively simple. Dirty water is pumped to the top of the filter, where it is evenly distributed over the top layer of sand. As water flows through the sand layer, suspended particles are trapped in the sand, while clean water passes through the sand layer and flows to the filter outlet.

The top layer of sand is often washed with clean water to remove trapped particles. This process is known as “backwash” and is usually carried out automatically by means of a timer or a reverse water flow.

It is important to note that the sand used in the filter must be of good quality and suitable for the type of water to be filtered. The sand layer must be kept clean and the thickness must be monitored regularly to ensure that the water is being filtered efficiently.

Additionally, sand filters can be used in conjunction with other types of filters, such as activated carbon filters or diatomaceous filters, to remove additional impurities.

The Sand Filter offers several benefits, including:
