Gravel and sand filter
product Description
Destiny
Gravel-sand filters are designed for filtering water used in gardening for drip irrigation and micro-sprinkler irrigation. Depending on the used sand or gravel filter batches, the filter purifies water from mechanical mechanical impurities such as sand, silt and biological particles such as algae and microorganisms of fresh surface waters. With a suitable fine-grained charge, they are also used to filter deep water after aeration in iron removal systems. Filters usually work as fast filters in pressure installations with a pressure not higher than 0.6 MPa.
Construction and principle of operation
The cylindrical, vertical, steel, welded, hot-galvanized tank in the bottom bottom has a horizontal partition with the filter nozzles located on the entire surface, axially in the upper and lower head there are externally threaded inlet and outlet connections. In the upper bottom and the front wall there are hatches for filling, emptying and filtering the filter bed, the tank is placed on four legs adapted to be placed on the frame base.
The filtration feed in the form of coarse gravel covers a layer of 3 cm, the surface of the filter nozzles serving as a support for a fine-grained filter element.
The stream of contaminated water pumped through the upper stub is scattered on the concave plate ensuring uniform loading of the entire filtration surface of the sand. The water is filtered from all impurities on the upper layer of filtration sand, it flows through the entire volume of sand, gravel, filter nozzle slots into the chamber under the partition and the bottom outlet nozzle.
The appropriate thickness of the filtration layer and the distribution of nozzles across the cross section of the filter ensures a laminar flow of water with the entire volume of the filter mass, eliminating the possibility of creating drains and channels permeating unfiltered water. Rinsing the bed is done by reversing the water flow direction, this is usually done when the pressure difference caused by silting the water filter between the inlet and the filter output exceeds 0.5 Atm.
Gravel sand filters are connected to a filter battery. Due to the optimization of the rinsing process, the use of three or more filters is the most appropriate in one battery. The use of a single filter forces you to rinse it with dirty water or install a hydrophore tank for clean water.
