Water Clarification and Media Filtration: Remineralisation and PH correction

PROVEN AND COST-EFFECTIVE TREATMENT METHODS FOR TYPICAL WATER POLLUTANTS: TURBIDITY, IRON, MANGANESE, ARSENIC, PESTICIDES, ETC..

Water remineralisation and PH correction with calcite filtration

The optimum water composition from a PH and hardness point of view is that with a PH between 7.5 and 8.5 and hardness between 60 and 200 mg/l as CaCO3. If water is too soft (too low calcium and Magnesium composition) it can be very corrosive and it is recommended to restore some hardness.

Calcite (calcium carbonate media) provides a controlled PH correction to water reaching a non-corrosive equilibrium. It does not overcorrect under normal conditions if overexposed.

As the Calcite’s calcium carbonate neutralizes the water, it will increase the hardness by increasing the dissolved Calcium and Bicarbonate of the water.

Water remineralisation is strongly recommended for reverse osmosis permeate when it is for human use.
