In order to keep the water clean and clear, it is necessary to fit a pool filter and a pump. The pool's mechanical cleaning takes place via the pool filter, which filters out particles down to about 25 um (thousandths of a millimetre). The central valve on the filter tank controls the water flow through the filter. The filter is 2/3 filled with filter sand, grain size 0.6-0.8 mm. As the dirt accumulates in the filter, the back pressure increases and is read off in the central valve's pressure gauge. The sand filter is backwashed once pressure increases by about 0.2 bar after the previous backwashing.
