Introduction/Overview on Sulphate removal system
The treatment system was developed so that it could be easily fitted to existing effluent treatment plants or a new plant built incorporating the effluent treatment within one plant. The technology has been developed so the effluent plant can remove all contaminants with a single settlement/solids-liquid separation and dewatering step.
The aim of the technology was to provide a method to allow the removal of sulphate below consent limits without producing a waste that required further treatment, the process was designed to be single stage and reaction time to be no longer than one hour. This is important as this enables the space required for the plant to be minimised.
The technology has an added benefit of producing an effluent which does not lead to scale formation e.g. limescale, that some effluents/plants have as a major problem. This is achieved as a direct result of the chemistry and does not require any additional chemicals to be added.
