WATEX RCTB series filters are designed to purify water from turbidity, colorfulness, iron, manganese and odor for villages, cities and industrial enterprises. Mainly it is used for groundwater purification.
RCTB filter operating principle is based on aeration and filtration. When water is aerated, iron, manganese and mechanical impurities form sediments, which can be filtered. Suspended solids are filtered through filtering material, which has been poured in to filter. Filters depending on pollution levels and water consumption have to be rinsed regularly. Filters after rinsing are regenerated and can purify water. Equipment consists from reactor, filter and compressor.
Pressure filter tanks are made from fiberglass with inner PE coating that can hold pressure up to PN10. Also available galvanized metal pressure tanks as well as steel tanks with food grade color coating and stainless steel tanks.
For water purification filtering media Aqua-Mandix and quartz sand with different grain size (0.4-0.8mm, 1-3 mm, 3-5mm) is being used. Porous structure of Aqua-Mandix provides a large active surface and provides efficient adsorption and accumulation of sediments.
The filter is equipped with an automatic Clack control which performs filtering and rinsing sequences automatically. Usually rinsing is performed at 2:00 at night.
For water aeration it is necessary to install air compressor. Air is injected in the water before it enters reactor.
Filters will provide with good quality water if operating personnel will ensure proper air supply, and unnecessary air removal and regular rinsing processes. Water purification system does not require specific chemical admixtures that have to be refilled.
