Midfield Meat Leads the Way

29 August 2002

Baleen Filters supports Midfield Meat at Warrnambool in Vic in their decision to explore new technology to deal with an environmental problem that has existed in the meat industry for decades. Wastewater treatment within the meat and by-product processing industries has traditionally been reliant upon secondary treatment (DAF), settling and anaerobic / aerobic processes.

The wastewater treatment facility at Midfield Meat goes against traditional methods that are fraught with numerous problems. Midfield Meat demonstrates innovative ‘thinking’ towards handling wastewater discharge that is ex processing operations.

Their approach centres upon stream splitting into hot (red) and cold (green) streams and separation of solids constituents to alleviate biodegradation of suspended matter. Therefore, reducing BOD and odour generation.

Separation of solids and greasy matter (by screening) is conducted over a number of stages. This involves removal of offal remnants (to 5mm), paunch debris (to 1mm), and coarse fines (to 250 micron) using conventional technology. This is followed by ‘Baleen’ fine screening of all visible fines, including suspended grease, (to 125 micron) and non-visible fines (to 65 micron).

In total approximately 20 - 25 tonnes of solid matter is recovered from wastewater discharge per day. The aim of intensive screening is to keep the majority of the solids ‘chemical free’ so it allows it to be safely used in composting operations.

Screening trials are to commence early in 2003 for flocculation of colloidal matter and fine screening (to 35 micron) to impart radical improvement in clarity of filtered wastewaters prior to re-use or disposal.
