FILTRATION BACKWASH PROCESS
Yardney cooling tower filtration systems are designed to remove inorganic and organic suspended solids while utilizing an automatically controlled backwashing system based on pressure differential or elapsed time. The backwashing function utilizes a portion of the clean filtered water produced by multiple tank systems to backwash the media bed in each tank until the entire system has been fully backwashed. Single tank systems utilize the cooling tower water for backwash water or external backwash water sourcing systems, available for both single and multiple tank systems.
