Low carbon footprint can be achieved by using Clean TeQ Waters sustainable turn-key water treatment solutions.

Low Carbon Water Treatment

The Carbon Footprint of Water

Global warming caused by greenhouse gas emissions has a severe impact on the water security of industries and society. Companies around the world are taking action to reduce their carbon footprint, and water treatment and supply can be a substantial source of direct and indirect greenhouse gas emissions. Achieving low carbon water level is becoming a global priority for the manufacturing sector, and in the municipal sector over 65 water/ wastewater utilities have already committed to net zero emissions targets.

The carbon footprint of water treatment is comprised of the three main greenhouse gasses, carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). The comparative impact of CH4 is 25 times greater than CO2 over a 100 year period, and N2O is 300 times greater, both of which are directly released (as scope 1 emissions) during sewage treatment. CO2 emissions are mostly the result of power use and fall under scope 2 emissions. The International Water Association reports the total GHG of municipal water treatment and supply being 3 to 8% of a country’s total GHG emissions, with higher values expected when including industrial water treatment.

In the water sector, direct emissions of NO2 and CH4 make up a larger percentage of total emissions compared to most other industries. With the rise of green energy, the GHG intensity of power supply is gradually declining throughout the world, and the direct emissions of the water sector will eventually need to be addressed.

CNQ's Low Carbon Water Treatment

We supply turn-key water treatment plants around the world with an eye on ESG objectives including high water efficiency, low energy use, and low by-product volumes. We believe companies can and should be working towards lowering the environmental footprint of their water supply and water treatment.

Clean TeQ Water can help companies and utilities towards that goal in a number of ways:

  • Our CIF® and DESALX® continuous ion exchange technologies reduce the reliance on membranes which is one of the main contributors of electricity use (and carbon emissions) in water treatment.
  • Our BIOCLENS® systems can maximize removal and subsequent full conversion of NO3 towards N2 thus preventing N2O emissions.
  • Our EVAPX® technology requires less energy compared to traditional evaporation / crystallization solutions and can use low-grade waste heat as the primary energy source further reducing the carbon footprint.
  • Our graphene membranes are expected to cut energy use by almost half compared to similar existing membranes.
  • Most of our solutions are built to minimize brine waste volumes which reduces subsequent energy intensive processing and/or trucking of waste.
  • Our continuous ion exchange approach has much lower chemical consumption, reducing overall emissions considerably (scope 3).

Using less energy with our water treatment technologies can not only reduce your direct and indirect emissions but would also typically reduce the operating cost of your water treatment. Contact us to jointly explore how to reduce your emissions and contribute towards a lower carbon world.
