Dosage
In the useful dosage range of 1-15 ppm, control of a wide range of inorganic scales at up to 100 x saturation values is possible. By monitoring the concentrate stream and trend charts, optimal dosage can be achieved for the control of scales, including those from calcium carbonate, calcium sulfate, barium sulfate, strontium sulfate, iron hydroxide, aluminum hydroxide, and silica.

Applications of Pretreat Plus® S1000 Antiscalant
Pretreat Plus®-3100 most ideally should be injected into the feed stream prior to the static mixer and the cartridge filter. Effective pH range is 3–12. If frozen, may be thawed and mixed before use. Stability is excellent, but best used within 12 months.
