Sewage treatment is the process that removes the majority of the contaminants from wastewater or sewage and produces both a liquid effluent suitable for disposal to the natural environment and a sludge. To be effective, sewage must be conveyed to a treatment plant by appropriate pipes and infrastructure and the process itself must be subject to regulation and controls. Some wastewaters require different and sometimes specialized treatment methods. At the simplest level, treatment of sewage and most wastewaters is carried out through separation of solids from liquids, usually by settlement. By progressively converting dissolved material into solids, usually a biological floc which is then settled out, an effluent stream of increasing purity is produced.

We provide a range of hand held and on-line process-monitoring instruments that have been cost effectively designed for measuring and controlling the main waste water parameters for municipalities, industrial plants (steel & metal, pulp and paper, chemical, mining, textile, petroleum, and food processing industries) and environmental service companies/organisations.
