OPERATION CONCEPT OF WATER TREATMENT PRIMARY FILTERS.
Water treatment primary filters developed by SPC PromVodOchistka LTD are equipped with Arkal filter elements manufactured in Israel. The product slate covers a wide range of capacities from 6m3/h to 160m3/h.
Arkal products included into the Company’s catalogue may be conditionally divided into three groups:
• filters with hand flushing;
• filters with automatic flushing:

- 2” SpinKlin Series;
-3” SpinKlin Series.
The key working part is a pack of polymer rings closely tightened with each other. Water flow passes through this pack thanks to small grooves available on disk surface. Closely tightened disks form a bulk structure with strictly defined parameters. Surface roughness overall dimensions define a diameter of flow channels and a degree of treatment accordingly. Sizes of retained particles vary from 20 to 400µm. In order to simplify identification of filter elements a color scale is used. Disks of fine (secondary) filters are made of grey color polymer, disks of primary filters – of black color polymer.
A filter element is installed into a filter body - filter ring. Incoming water flow passes into the body, then it passes via flow channels between disks and is discharged through an outlet port.
ADVANTAGES OF WATER TREATMENT PRIMARY FILTERS.
• extensive opportunities relative to a capacity and a degree of treatment;
• constructability of multistage filtration systems;
• simple design;
• simple implementation of flushing mode;
• use of non-corrosive materials;
• long-term (up to 15 years) period of operation.
