Soda, Na2CO3 for pH adjustment

The purification process at a groundwater treatment plant usually has significantly fewer steps than for surface water. In addition to aeration/oxidation and rapid filtration, the pH needs to be adjusted. Most often, lye or soda ash is used.

Tomal’s system is very suitable for dry dosing of soda ash, as we usually include a customized silo plant with dosing equipment. Thanks to the excellent accuracy of the multi-screw dosing unit and its safe delivery, the correct pH level is ensured, which should normally be around 8.
