Supercritical UV™ Disinfection System Effectively Disinfects Primary Treated Meat Plant Effluent
A meat processing plant were investigating ultraviolet disinfection options for their wastewater treatment to achieve an E. coli consent requirement of median <1,000 cfu/100mL.
A trial using a NovoLabs™ Supercritical UV™ disinfection system was set up at the site to analyse the efficiency of treating effluent from the end of their existing primary Dissolved Air Floatation (DAF) treatment system.
A typical DAF treatment system
The inlet conditions after the DAF treatment (i.e., before ultraviolet treatment) averaged an ultraviolet transmittance (UVT) of 11.6%, and a TSS of 50 g/m³.
The inlet E. coli concentration averaged 6.9 million cfu/100mL with a median of 1.2 million cfu/100mL. The highest recorded E. coli concentration was 23 million cfu/100mL.
Using the Supercritical UV™ disinfection system E. coli were reduced to an average of just 55 cfu/100mL!
