Components and characteristics of a multi-grade filter include:
· Filter Bed: The filter bed in a multi-grade Purify typically consists of layers of filter media organized in decreasing order of particle size from the top to the bottom. ordinary filter media used in multi-grade filters involve sand and gravel. The finer media are set at the top, while the coarser media are position at the bottom.
· Backwashing: Multi-grade filters are provide with a backwash system that periodically washed the filter bed by reversing the flow of water. This procedure dislodges and removes the trapped particles, restoring the filter’s presentation.
· Filtration Efficiency: Multi-grade filters are studied for their high filtration efficiency and are able of removing particles in the range of 10 to 50 microns. They are acceptable for removing turbidity, suspended solids, and some kind of organic matter from water.
· Applications: Multi-grade filters are naturally used in water treatment plants, industrial processes, and wastewater treatment space. They are suitable for pre-treatment of water before more treatment processes such as reverse osmosis, softening, and disinfection.
· Ease of Maintenance: The backwashing action and the robust design of the multi-grade filter make it proportional easy to maintain and operate. The filter media may want to be replaced periodically, turn on the quality of the source water and the operating conditions.
