Chemical additives, such as coagulants, are often used in conjunction with the filtration system. [1]: 7–9 The two types of rapid sand filter are the gravity type (e.g. Paterson's filter) and pressure type (e.g. Candy's filter). A disinfection system (typically using chlorine or ozone) is commonly used following filtration.
Two methods are commonly used to do this. In the first, the top few millimetres of fine sand is scraped off to expose a new layer of clean sand. Water is then decanted back into the filter and re-circulated for a few hours to allow a new biofilm to develop. The filter is then filled to full volume and brought back into service. [10]
In water purification plants, there is usually a high energy, rapid mix unit process (detention time in seconds) whereby the coagulant chemicals are added followed by flocculation basins (detention times range from 15 to 45 minutes) where low energy inputs turn large paddles or other gentle mixing devices to enhance the formation of floc.
Pressure filter systems have a water inlet and outlet with the inlet site at the top and the water outlet at the base of the filter. As the water flows through water inlet, it will encounters a grid assembly covered in synthetic cloth which provides support for the diatomaceous earth cake. [ 19 ]
A water filter removes impurities by lowering contamination of water using a fine physical barrier, a chemical process, or a biological process. Filters cleanse water to different extents, for purposes such as: providing agricultural irrigation , accessible drinking water , public and private aquariums , and the safe use of ponds and swimming ...
