Any company that discharges into sewer systems, lakes, streams or other surface waters are required to neutralise this effluent before allowing it to be discharged or treated further in biological processes, such as anaerobic or activated sludge. Non-compliance could result in fines and other consequences. In many instances, recording the pH of the discharge is also required.
Traditionally, sodium hydroxide (caustic soda) and calcium hydroxide (lime) have been used to neutralise acidic solutions. However, these compounds are reactive and can cause high pH levels if not controlled correctly. The Magmex range is the environmentally friendly answer to the neutralisation of acidic wastewater.
