Food Processing – Abattoir (Ovine and Bovine)

M. C. Herd Pty Ltd

Corio, Australia

Our objective was to improve the quality of waste water from the abattoir.

The contaminant material present in the waste water prior to the introduction of Solutek Organic Concentrate included traces of blood, paunch waste, oil and grease etc. which contributed to Trade Waste charges.

The plant operated a treatment process consisting of Coagulation, twin DAF’s, Trickling Filter and Filter Press to treat the effluent produced prior to discharging to the local Water Board sewer. However, residual Chemical Oxygen Demand/Biochemical Oxygen Demand, Total Kjeldahl Nitrogen, Total Oxidised Sulphur and Suspended Solids post effluent treatment was a concern and extrapolated to periodic non compliance and a significant cost to the business.

The amount of residual Organic loading, once discharged to the sewage conveyance network was potentially leading to septicity, odour and corrosion issues within the network in general.

Results

Following the introduction of Solutek Organic Concentrate to the waste water, significant reductions were found in Suspended Solids, Total Kjeldahl Nitrogen and Chemical Oxygen Demand. There was a significant reduction in odour and in oil and grease.
