Many production plants have problems in keeping the pH value stable in the effluent waste water. In most cases the pH value has to be decreased, and mineral acids are commonly used. But the equipment for this is costly and secondary problems will occur, the use of sulphuric acid will also add sulphates into the water, and hydrochloric acid is highly corrosive for pipes and equipment. Thus you end up with new problems and high operating costs. The handling of such acids is hard to keep safe.
We offer safe carbon dioxide-based pH control systems which are easy to operate and need only low attendance.
Carbon dioxide forms a weak acid offering a much more accurate and safe pH control, overdosing is now impossible and the equipment is much more simple and less expensive. In addition the buffer capacity of the treated water will improve significantly.
