Chains used for collecting accumulated sediment in setting basins and sedimentation basins or removing the collected sediment in sewage treatment method amenities together with other water remedy facilities need specially high resistance to corrosion and put on since they can be right exposed to sewage and sludge. A dirt getting rid of chain is moved at a rather rapid speed on an almost vertically set up rail, 
though the operation frequency is minimal, so WS Variety Roller Chain is employed. Conversely, a chain for raking up and/or out filth is driven at a very slow speed and will not need rollers, so WAS Variety Bush Chain is used.
Eighteen forms of WS Kind and 6 types of WAS Sort Chain can be found.
(a) WS Style Roller Chain
A WS Form Roller Chain is made to deliver high corrosion resistance and wear resistance for lengthy support during the significant surroundings of water treatment applications.
Because the operating time of this kind of equipment is relatively brief, pins and bushings of hardened stainless steel and other elements are produced of unique alloy steel to ensure smooth bending in the chain, and superb wear and corrosion resistance.
(b) WAS Sort Bush Chain
Heat handled stainless steel offers this chain with superb performance for corrosion resistance and dress in resistance.
BF Kind Bushing Chain for Water Treatment Drive Unit
This chain is utilised to connect water treatment method products to a electrical power supply. Inside the past, JIS/ ANSI variety roller chains were employed. For enhanced corrosion resistance, each of the parts are now manufactured of 13Cr stainless steel. Because the chain is operated at a slow velocity, a bushing chain with out rollers is employed. The sprockets are interchangeable with JIS/ ANSI roller chain sprockets.
We manufacture seven kinds of BF Form Bushing Chains within a range from 120 to 240, which include heavy-duty form.
