Liquid Alg-Erase™
Non-Foaming Cooling Water Biocide
BIOCIDE FOR COOLING WATER
Liquid Alg-Erase™ is a broad-spectrum treatment that controls algae, bacteria, and slime in open cooling tower systems, decorative fountains, and other industrial water applications. More effective than liquid bleach across a wide pH range, it delivers dependable performance while minimizing operating costs.
CONSISTENT CONTROL IN CHALLENGING WATER CONDITIONS
Suitable for cooling towers, food processing equipment, decorative fountains, and air washer systems, Liquid Alg-Erase™ provides strong microbial control without foaming. Its versatility and compatibility with simple feed systems make it a reliable choice for maintaining clean, efficient water flow.
BASIC GUIDELINES: As a general rule, the total bromine level should be checked with a chlorine or bromine test kit at the bleed-off point furthest from the point of injection. This product is UV light sensitive, and may be applied at nighttime in most systems if excessive exposure may be a limiting factor. Do not store product in clear or transparent containers. Initial dose: When the system is noticeably fouled, a precleaning may be necessary. Then apply sufficient Liquid Alg-Erase to achieve 2.4-15 ppm total bromine (1-6.6 ppm as chlorine) or as needed to maintain microbial or algal control.
Subsequent doses: This product may be added using continuous or intermittent dosing methods to provide adequate control. Continuous addition methods may obtain adequate control at lower total bromine levels than suggested above. Always adjust levels of total bromine accordingly to maintain desired visual or measured microbiological control.
INDUSTRIAL & COMMERCIAL RECIRCULATING COOLING WATER, HEAT TRANSFER SYSTEMS and PASTEURIZERS (Such as Evaporative Condensers, Hydrostatic Sterilizers and Retorts, Dairy Sweetwater Systems, Food and Beverage Pasteurizers and Once-Through Cooling Water Systems): Liquid Alg-Erase should be applied directly to the cooling water at any section of the system where sufficient mixing will occur. This product should be applied to the cooling water to provide a total bromine level of 1.0-15 ppm. Liquid Alg-Erase added at a rate of two fluid ounces per 1000 gallons of water gives a dosage of approximately 3.4 ppm of total bromine, but higher dosages may occasionally be required to provide the desired bromine level throughout the systems. The total bromine level should be checked with a test kit and additional product applied until a reading of 1.0-15 ppm is obtained at the bleed-off point. Some systems may be maintained in satisfactory biological condition by applying this dosage once per day while others will respond better to dosages less than once per day. Some systems may be maintained in satisfactory biological condition by applying this dosage intermittently while others may require a continuous application.
COOLING PONDS, LINED RESERVOIRS AND DECORATIVE FOUNTAINS: This product may be applied at the lined reservoir, pond, or fountain inlet or at a location that permits complete diffusion into the water at maximum retention time before reaching the outlet. Sufficient Liquid Alg-Erase should be fed to maintain a total bromine level of 1.0-15 ppm in all parts of the reservoir or pond (two fluid ounces per 1000 gallons of water yields 3.4 ppm total bromine). Some systems may be maintained in satisfactory biological condition by applying this dosage once per day while others will respond better to dosages less than once per day.
SHELL EGG PASTEURIZER WATER SYSTEMS: For control of bacteria and associated slime in shell egg pasteurizer water systems add 2-6 ounces of this product per 1000 gallons of system water to achieve control. To maintain control add a sufficient amount to maintain 1.0-9 ppm total bromine throughout the system. (Two fluid ounces per 1000 gallons of water yields 3.4 ppm total bromine). (not for use in California)
AIR WASHERS: (This product may be used only in industrial air washers and air washer systems which have mist-eliminating components.): For control of microorganisms in industrial air washer systems add this product to the air washer sump or chill water to provide a total bromine level of 1.0-9 ppm. Badly fouled systems must be cleaned before treatment is begun. Liquid Alg-Erase at a dosage of two fluid ounces per 1000 gallons of water gives a dosage of approximately 3.4 ppm of total bromine, but higher dosages may occasionally be required to provide the desired bromine level throughout the systems. The total bromine level should be checked with a test kit and additional product applied until a reading of 1.0-9 ppm is obtained at the bleed-off point. Some systems may be maintained in satisfactory biological condition by applying this dosage once per day while others will respond better to dosages less than once per day.
FOR PULP & PAPER MILL INFLUENT WATER SYSTEMS: This product should be applied to the raw water intake prior to the filter house, economizer, or process water. Feed at a dosage sufficient to provide a total bromine level of 1.5-9 ppm. This product at a dosage of two fluid ounces per 1000 gallons of water, gives a dosage of approximately 3.4 ppm of total bromine, but higher dosages may occasionally be required to provide the desired bromine level throughout the system. Some systems may be maintained in satisfactory biological condition by applying this dosage intermittently while others may require a continuous application. This product may be used in pulp and paper influent water systems where the manufactured paper or paperboard may be used for food contact purposes. (not for use in California)
FOR PULP & PAPER MILL PROCESS WATER SYSTEMS: This product should be added to a paper making system at a point of uniform mixing such as the beaters, broke chest pump, save-all tank, or white water tank. Feed at a dosage sufficient to provide a total bromine level of 4-8 ppm. Liquid Alg-Erase at a dosage of two fluid ounces per 1000 gallons of water gives a dosage of approximately 3.4 ppm of total bromine, but higher dosages may occasionally be required to provide the desired bromine level throughout the system. Some systems may be maintained in satisfactory biological condition by applying this dosage intermittently while others may require a continuous application. Liquid Alg-Erase may be used in pulp and paper mill process water systems where the manufactured paper or paperboard may be used for food contact purposes. (not for use in California)
OIL AND SECONDARY OIL RECOVERY SYSTEMS, DRILLING MUDS AND PACKER FLUIDS: This product may be used to treat water used in primary or secondary oil or gas recovery systems to control the growth of anaerobic sulfide-forming bacteria and aerobic slime-forming bacteria. Liquid Alg-Erase may be used in seawater or fresh water, recycled or disposal/recovery systems, muds or fluids. Liquid Alg-Erase controls biological and slime deposits on pumps, pipework, heat exchangers, and filters associated with oilfield and gasfield systems. It also controls slime deposits downhole in formations. Add sufficient amount of Liquid Alg-Erase to achieve satisfactory biological control. Initial recommended dosing levels of 2.2 to 50 pm as total Bromine are suggested. A dosage of two fluid ounces per 1000 gallons of water yields approximately 3.4 ppm of total bromine. NOTE: Halogen dosages listed in the various applications are expressed as bromine. Since most field test kits for oxidizing halogens give values in terms of chlorine, simply multiply the reading from the test kit (as chlorine) by 2.25 in order to obtain the bromine equivalency listed in these directions.
Subsequent doses: This product may be added using continuous or intermittent dosing methods to provide adequate control. Continuous addition methods may obtain adequate control at lower total bromine levels than suggested above. Always adjust levels of total bromine accordingly to maintain desired visual or measured microbiological control.
