Silica concentrations beyond 120 ppm can form a dense and highly insulating scale that is almost impossible to remove. Conventional polymers do not control silica precipitation. This problem is further aggravated in PO4 based treatment programs that operate at lower pH. Aquapharm's polymers offer a two pronged control over silica precipitation in phosphate based programs a) allow operating a PO4 based program at higher pH (where silica solubility is higher) and b) reduce silica precipitation.
Silica levels of 300 ppm can be easily maintained with these polymers.
For non-phosphate based programs, Aquapharm's polymaleic chemistry offers excellent silica control.
