Treatment & Dosage Requirements

In calculating the dose rate of Antiscalant For High Silica Water, the membrane manufacturer's operating limits and feed water quality should be considered. All dose rate calculations should be made on the computer projection programme "e-WATER 5.0", which calculates the SCR for Silica. Generally recommended dosage is 1 ppm in the feed water for every 6 to 7ppm of total silica in the feed water, depending on the operating pH and temperature. At 25°C, pH 7 to 7.5 with 240mg/l silica in the concentrate. Antiscalant For High Silica Water is normally dosed at 5.0 to 10 mg/L in the concentrate. Antiscalant For High Silica Water can be diluted with product water and should be applied continuously by means of a suitable metering pump. Continuous feed and correct level of Tacelene Chem is essential since silica fouled membranes are difficult to Clean. When both dissolved and colloidal silica is present, silica fouling can be difficult to predict because of the complexity of the silica reaction chemistry. Preventing the formation of substrate material like insoluble calcium and iron salts is required in eliminating silica fouling. We recommend very effective auto flushing devices to applied with high silica waters.

Principle Uses

Antiscalant For High Silica Water has been developed specially as a SILICA inhibitor, for waters with SCR <1.3 to 4.2 mg/l.

Handling
