What is DIATOMACEOUS Earth filter?

DIATOMACEOUS EARTH is a filter, usually for pools or drinking water made of DIATOMACEOUS Earth. The filter is the most common and effective filter on the market. It can remove eyelashes, cysts and asbestos from the water and is approved by the Agency for Protection of the Environment (EPA) as a method of drinking water filtering. However, it is not so effective in removing color and other dissolved ingredients. This light rock is white to whitish and easily crumbles into powder. The silica dioxide is the main role of the typical chemical composition of the rock to eighty -five percent, but also contains sodium, magnesium and iron. D.E. It is made of fossils of diatoms, the type of algae, the size of which ranges from five micrometers to one hundred micrometers. The diatomate composite has no odor or taste and is chemically inert, which makes DIATOMACEOUS EARTH filter an attractive option for filtering drinking water and other consumed fluids such as syrup or beer.

diatomThe country was first used in World War II as a drinking water filter for the United States Army. The filter had to be light to meet the needs of mobile army operations, but still able to produce clean water. US Army Engineering Research and Development Laboratory (ERDL) came up with D.E. A filter that was used in the pools after the war. The filter was then used as a drinking water filter, especially for small municipalities.

DIATOMACEOUS EARTH FILTER mechanically directs the water of its contaminants. D.E. The cake is connected to the filter sheets and rinsed by the filter system so that the thin layer D.E. accumulates on a septum or grid filter. The septum is a plastic or wire fabric pulled through a steel frame. Once a preliminaryayer of D.E. was on the septum, another low dose of D.E. It is introduced into the system. The DIATOMACEOUS Filter then makes unwanted particles part of the filter and passes through clean water through microscopic pores.

Over time, the filter causes a loss of head flow. Because the filter of the DIAThe Tomaceous Earth filter works by adding the mass to the layer in front of the truck, eventually the water is defended, so even clean water cannot pass. When this happens, the filter must be cleaned. This is achieved by separating the cake with a high -pressure spray and cleaning the filter. D.E. is usually discarded and new d.e. The cake is connected to the filter sheets and rinsed to form a new layer in front of the cart.

There are two types of DIATOMACEOUS Land filters: pressure filter and vacuum filter. The pressure filters are closed in pressure chambers and have a pump or a source of high pressure water at the inflow site. Vacuum filters are open for atmosphere and have a pump located on the drain side of the filter. D.E. The filters are attractive to many operators because they are relatively cheap for installation and do not use chemicals.
