The properly selected bottom collection and distribution assembly significantly improves the filtration quality, and has an impact on hydraulic process of incoming water passing through the filtering medium, on regeneration process, and, thus, on filter’s performance.

The bottom collection and distribution assembly is manufactured according to Specifications TU 4859-003-33513134-2008 “Drainage assembly” and registered on December 10th, 2008 under №047/0001088.

Our company manufactures four types of drainage distribution assemblies of various purpose and design equipped with the slotted caps, radial pipes for bottom distribution assembly and "TEKO SLOT" spirally-wound elements:

• Bottom distribution assemblies on the concrete foundation
• Bottom distribution assemblies of duplicating type
• Bottom distribution assemblies of "false bottom" type
• Bottom distribution assemblies for rapid gravity filters

The bottom drainage distribution assembly is designed for collection and drainage of water and regeneration solution from the filter, as well as for supply of washing water or regeneration solution.

The bottom collection and distribution assembly is manufactured from 12X18N10T stainless steel and high quality plastics: ABS (acrylonitrile-butadienestyrene), PP (polypropylene), PVC (polyvinyl chloride). On a case-by-case basis the drainage distribution assembly could be made of steel in combination with plastics.

The specialists of "TEKO FILTER" company perform strength and hydraulic calculations for all manufactured internal drainage distribution assemblies, including radial pipes of bottom distribution assemblies, define the required number of filtering elements based on specified filtration and backwash rates, as well as elaborate design and process documentation.

Advantages of bottom distribution assemblies manufactured by "TEKO FILTER" company:

• guaranteed slot dimension: sizes of 0.2 and 0.4 mm eliminate the risk of expensive filtering medium removal;
• resistance to high temperatures;
• enhanced mechanical strength;
• resistance to hydraulic impacts;
• low hydraulic friction;
• cost reduction due to easy replacement of slotted caps;
• absence of "blind" (non-washable) areas due to the properly selected number of filtering elements and their location;
• possibility of application in food industry.
