Clean clogged underdrains with Blue Earth Labs filter cleaning products

Filter Underdrain Cleaning

The same deposits that affect filter media can also clog air scour systems and filter underdrains.  These deposits reduce the efficiency of backwashes, increase both downflow and backwash head pressures and lead to an increase in water and energy usage.

Prior to Media Master® and Media Master® RR, the only practical way to deal with clogged underdrains was to remove the filter media and replace the underdrains or clean them by hand. Filter underdrains can be cleaned independently of the filter media or can be cleaned in conjunction with the filter media.  Media Master and Media Master RR can be dosed to assure that the reaction penetrates and cleans the underdrains in place. Our filter underdrain cleaning process chemically removes all types of organic and inorganic deposits including biofilms, iron, manganese and calcium scale.
