Industrial wastewater treatment

There are several types of industrial wastewater, originating from processes in

  • Mining industry
  • Food and dairy industries, slaughter houses and breweries
  • Pulp & paper industry
  • Steel industry (pickling and electroplating baths)
  • Textile industry (dyeing)
  • Petroleum refinery
  • Surface water treatment chemicals production.

Technology advancements range from conventional treatment such as clarification and filtration processes to highly developed treatment such as membrane separation techniques. In order to treat wastewater, it is generally necessary to combine a number of basic processes, which may be physical, chemical or biological in nature.

Typically, any wastewater treatment techniques consist of the Main Treatment process, preceded by a Pre-Treatment scheme and followed by a Post Treatment process. Wastewater effluents can be further treated in downstream Polishing Loops. Treatment schemes are largely dependant on the Applications encountered in different Industries.

Crosstek offers a range of consultancy and engineering services relating to the design, installation, enhancement, refurbishment and replacement of wastewater treatment plants.

Crosstek is able to identify proven cost effective solutions for new and improvements to existing wastewater treatment schemes.
