|NOTE: AQL 29 must be maintained in the cooling tower at all times to ensure that a sufficient level of treatment is present to dissolve the existing scale. |
AQL 29 is not effective on silica scale. Scale thicker than ¼ inch should be descaled with an acid type product. AQL 29 works with the system over a period of months by sequestering deposits and scale. One-line descaling may take six months or longer for scale removal.
PRODUCT DOSAGE: For on-line descaling, add 1 gallon of AQL 29 per 2,000 gallons cooling tower capacity. Maintain dosage based on bleed off. Product dosage may vary up to 1 gallon per
700 gallons of bleed off.
WHEN USED AS A DESCALER: AQL 29 is liquid blend of sodium polyacrylate polymer. It is effective in all cooling towers, especially systems that collect silt and airborne debris.
The high-molecular weight polymer lifts and suspends mud, silt and iron oxide and allows their removal through normal bleed off.
