WATER QUALITY PROBLEM
Iron and manganese often causes the main problem of the waterworks. When water gets in contacts with air, it changes the colour, turbidity increases and sediments appears. Water has a metallic taste. Water pipes are clogged and sanitation at the consumer becomes dirty. Suggested concentration of iron should be 0.1 mg/l and manganese 0.05mg/l.
SOLUTION
The best solution for this problem is oxidation and sand filtration. WATEX RCTBx3 series filters are designed to purify water from turbidity, colourfulness, iron, manganese and odor for villages, cities and industrial enterprises. Mainly it is used for groundwater purification.
OPERATING PRINCIPLE
RCTBx3 filter operating principle is based on aeration and filtration. When water is aerated, iron, manganese and mechanical impurities form sediment, which can be filtered. Suspended solids are filtered through filtration media, 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 and three filters.

PRECONDITIONS
SYSTEM MAINTANANCE
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.
PRESSURE TANK
Pressure filter tanks are made from fiberglass with inner PE coating that can hold pressure up to PN10.
FILTRATION MEDIA
For water purification filtration media AquaMandix and quartz sand with different grain size (0.4-0.8 mm, 0.7-1.25 mm, 1-3 mm, 3-5 mm) is being used. Porous structure of AquaMandix provides a large active surface and provides efficient adsorption and accumulation of sediment.
CONTROL VALVE
The filter is equipped with an automatic Clack control valve which performs filtering and rinsing sequences automatically. Usually rinsing is performed at 2:00 at night.
AIR SUPPLY
For water aeration it is necessary to install air compressor. Air is injected in the water before it enters reactor.
