What is Industrial Water Reuse and Recycling?

Industrial water reuse and recycling is the process by which wastewater produced from one source (such as municipal wastewater) is treated so it can be used in an industrial process. Sometimes the source wastewater may be produced by the same industrial facility that treats it and reuses it.

Industrial wastewater can be recycled on or off site depending on space constraints and budgetary considerations.

Recycling wastewater is important for the natural environment as it avoids straining drought-stricken areas and natural habitats such as wetlands.

 Benefits of Water Recycling

​The benefits of recycling industrial wastewater are many:

  • Reducing fresh water costs

  • Increasing operational efficiency

  • Reducing wastewater flows

  • Improving production capacity due to increase availability of clean water

  • Providing good "corporate citizenship" in your community, particularly in regions where seasonal droughts can occur

  • Reducing the size of your water footprint

  • Impacting the image of your company positively. If negative publicity around a company's water use can adversely impact a company's sales/growth then positive attention for water recycling can be beneficial.

 Common Industrial Water Reuse Opportunities

​Industrial water may be reused in many different ways. Before determining how to reuse waters, you should consider where potential water reuse opportunities exist.

Some opportunities for water reuse in an industrial plant may include:

  • Wastewater recycling

  • Cooling tower blowdown

  • Boiler blowdown

  • RO reject recovery and reuse

  • Once through cooling water

  • Collected rain waters

 The Need for Water Recycling and Reuse

Whatever is behind your need to recycle and reuse wastewater, decreasing your plant's water footprint is beneficial to your company and the community. The need for industrial water recycling and reuse has many drivers, including:

  • Industrial and population growth. A growing population increased the need for power generation, for example, which placed greater demands on water use.
  • Fresh water costs. The cost of clean, fresh water is continually increasing, and is impacting all regions.
  • Regulatory requirements. Many industrial sites have wastewater discharge permits that include flow and quality restrictions. Moreover, EPA Industrial Effluent Guidelines are often revised.
  • Social responsibility. Protecting the world's resources is a global concern: the general public is paying attention. Negative publicity around a company's water use can have an impact on a company's sales/growth.
  • Discharge costs. Sewer and wastewater costs have increased at a higher rate than fresh water costs.
  • Water scarcity. Many regions in North America are susceptible to drought. Additionally, some industrial plants have limited access to clean/fresh water.
  • Wastewater processing limitations. In many industries, plant wastewater treatment capacities have not increased proportionally with plant production. Plants are challenged to meet higher flows and have limited operational resources.
  • Sustainability efforts. Many companies strive towards sustainability by utilizing economically sound programs that help minimize a plant's negative environmental impact while conserving energy and natural resources.
