Neutralisation is necessary for successful wastewater treatment in a wide range of applications. A correctly adjusted pH value is vital for almost all wastewater treatment processes. Only neutral wastewater with a pH between 6.5 and 9.5 may be discharged into the sewage system. Acidic or alkaline wastewater must therefore be neutralised beforehand.
Products for this application
Which wastewater must be neutralised in industrial wastewater treatment?
- spent acids and bases
- rinse water and washwater containing metal salts
- acidic rinse water from pickling processes in metal surface treatment
- alkaline rinse water from pickling processes in metal surface treatment
- alkaline degreasing liquids from pre-treatment or cleaning of metal surfaces
- alkaline washwater from paint stripping
- active baths and rinsing baths from galvanic processes/wastewater from electroplating processes
- acidic phosphating baths and their rinsing baths
- pH adjustment for heavy-metal precipitation
- pH correction during the final pH check before indirect discharge
