COD Reduction

Your Challenge

Regulators stipulate strict limits of COD for water to be discharged to sewers or the environment.

Failure to comply with regulation can result in a loss of permit, operational downtime, limited production volume and severe fines. By adopting a wastewater treatment process which has the ability to remove trace levels of organics, you can meet regulation and prove commitment to the protection of the environment.

Primary and secondary treatment remove around 75-85% of the COD, but the hard-to-treat COD remains. Typically, the COD concentrations are from <120 ppm in the EU to <50 ppm in China so in order to meet a regulators standard for discharge, additional treatment is often required.

Chemical Oxygen Demand (COD) is used as a measure of organic pollutants in water and is expressed in milligrams per litre (mg/L) or parts per million (ppm).

Our Solution

Arvia’s on site ODC™ system provides a successful treatment solution for reducing COD for numerous industries worldwide. It can be retrofitted into an existing treatment train to remove the remaining hard-to-treat COD or as a standalone treatment, dependant on removal requirements. The system uses a minimal 18kwh/kg COD power due to the targeted nature of the treatment process.

ODC™ treated wastewater can also be safely reclaimed and reused for other purposes within the business, saving money and addressing high water demands in times of shrinking supplies.
