Industrial Wastewater and the Importance of Chemical Pretreatment

Industrial wastewater (or trade waste) is generally described as an array of contaminants which will negatively impact the environment if released incorrectly; with the result impacting the integrity of surface water, groundwater and the land.

  • Industrial processes create different kinds of impurities such as: fats from food processing, colourings, acids, oils and organic chemicals including paints, dyes, detergents or pesticides.
  • In order to mitigate environmental risks, Industrial Wastewater Pretreatment methods are utilised to remove pollutants prior to discharging or reusing the water.
  • Industrial Wastewater Pretreatment is important because sewage collection systems and water treatment plants can experience corroded pipes and equipment; if the toxic impurities from industrial & commercial wastewater are not properly discharged.

Industrial Wastewater Pretreatment Methods

An Industrial Wastewater (or trade waste) Management Program incorporates the legal, technical and administrative items required for safely controlling industrial wastewater discharge. Industrial Wastewater Pretreatment

  • Chemical Pretreatment is as simple as adding chemicals prior to discharge or integrating equipment into the process. The best solution is the one that offers the most effective capital and operating costs.

Benefits for your business or project

Typically, the program is designed to be proactive versus reactive and by implementing an Industrial Wastewater Management Program, you:

  • Decrease any possibilities to affect the operation of local sewage and water treatment plants,
  • Increase opportunities for wastewater and sewage sludge to be reused or recycled,
  • Stop untreated polluted water from passing through water treatment plants and into the receiving body of water that may result in devastating health or safety problems for the public or environment.



  • PR Water’s project approach includes an efficient but comprehensive consultation and testing process that ensures a proposal is designed specifically for your project’s needs, environmental requirements and budget.

  • Our range of equipment is available for long or short term rental and is also available for sale. The PR Water range of water & environmental equipment is strong, cost effective, mobile and is designed to be flexible to your project’s needs.
