At a meat processing plant required to reach below 800 MPN/100mL enterococci, the Supercritical UV™ disinfection system met the trade waste consent limit at an ultraviolet transmittance as low as 0.3%.
A meat processing plant discharging into the council trade waste scheme was required to reduce their enterococci concentration to below 800 MPN/100mL under a new regional trade waste bylaw. The plant utilises chemically-assisted dissolved air flotation to remove suspended solids from their wastewater prior to discharge.
Typical of meat works effluent, UVT was extremely low. Even with chemical pre-treatment, the maximum UVT recorded during the two-week test period was just 0.3%, massively below what is considered feasible for any conventional submerged lamp UV system.
When solids concentrations were maintained at levels required by the consent, the Supercritical UV™ system reduced enterococci to well below the required 800 MPN/100mL.
Following the trial, the customer procured a full-scale containerised Supercritical UV™ system as part of their total treatment plant upgrade. After installation, the system was confirmed as "easily meeting consent conditions."
Key operational features that influenced the purchasing decision included parallel processing, automatic lamp-outage detection with module changeover, and the slide-out rack design with flip-up lids for safe and clean operator access.
