Pretreatment Filtration Beverage Water Treatment Plant Sand Filter
Sand filter , it is the use of quartz sand as a filter medium, under certain pressure, the higher the turbidity of water through a certain thickness of the granular or non-grain Quartz sand filter, the effective removal of suspended solids in the water, organic matter, colloidal particles, microorganisms, chlorine, smell and some heavy metal ions, and ultimately to reduce the water turbidity, water purification effect of a high efficiency filtration equipment
1. Used to require industrial water turbidity ≤ 5mg / L to meet the drinking water quality standards of industrial water, domestic water and municipal water supply system;
2. Removal of suspended solids and solids in industrial effluents;
3. Can be used as ion exchange method softening, desalination system in the pretreatment equipment, the water quality is not demanding industrial water supply coarse filtration equipment;
As well as in the swimming pool recycling system, cooling the circulating water purification system.
Filtration -The process of filtration involves the flow of water through a granular bed, of sand or another suitable media, at a low speed. The media retains most solid matter while permitting the water to pass. This type of slow filtration over a granular bed is generally known as slow sand filtration. It is the oldest method of filtration but still widely used in municipal water treatment plants & for industrial application as well.
Application
Water treatment plant
Feed water of RO plant
Post treatment of wastewater treatment plant
Pretreatment of ion exchange based plant
Iron removal &Fluoride removal
Cooling tower water treatment plant.
Fountain, Water bodies and swimming pool
Rain water harvesting.
Gardening & washing application
River& lake water treatment.
Most frequently used filtration fillings:
Fine gravel: 1-20mm
Silica sand of various roughness: 0.4-2.5mm
Active charcoal: is used for absorption of chlorine and other mineral substances
Anthracite: is used in two-layer or multi-layer filtration of drinking water in connection with sand - the addition of anthracite guarantees a longer filter lifetime, it facilitates a larger filtration through-flow and reduces sand contamination
Catalytic mediums [YAMLOX®]: are used to remove iron and manganese from drinking water
Semi-burnt Dolomite limestone: is used to reduce water acidity
The filtration bed can be formed by one layer or more layers of various filtration materials. Filtration sand lifetime during a proper washing of filters oscillates around 8 years on a standard basis.
Filters are controlled manually [with ball valves / shut-off valves] or automatically. In the case of an automatic filter control process, membrane or hydraulic or pneumatic valves are used.
The entire automatic process of filtration and back washing of filters is controlled by a central control unit. The control unit makes it possible to set filter washing on the basis of time, pressure difference or filtered water quantity.
Filters are washed, on a standard basis with raw water or with treated water from reservoirs.
Filters are fitted with a filtration inter-bottom with jets. The jets are made of the ABS material and make it possible to wash with water or both water and air. In the case of the filling height not exceeding 1500 mm, the water flushing process is fully sufficient.
Pressure filters are made of carbon steel with a protective anticorrosion coating with epoxy resin in the RAL 5010 [gentian blue] or 5012 [light blue] colour shade. The coating meets the conditions of hygienic harmlessness for contacts with drinking water.

FAQ:
01. how small a solid needs to be removed,
02. how dirty the water is,
03. how the water will be used once it is filtered,
04. and the source of backwash water needed to clean the filters.
