pH correction may be required in some areas where the pH has been suppressed naturally or in industrial applications where the water pH has been adjusted to suit a process but needs to be neutralised prior to discharge to drain. In both cases, if there are contaminants in the water these should be removed prior to the pH correction unit. Acidic water can cause corrosion of pipework and equipment.
The most common approach to pH correction is to run the water through a bed of activated limestone. The pH levels of the water are gradually increased as the limestone bed dissolves. The pH can also be increased using a similar media and method. pH correction units can also be used to re-mineralise pure water derived from Reverse Osmosis or demineralised plant.
Over time the activated limestone will be consumed and will need to be replaced. This is easily done as activated limestone is an inert product.
