Heinz Australia’s Golden Circle plant in Brisbane upgraded to a rotary drum screen from CST Wastewater Solutions to achieve sharply improved solids capture and reduced solids waste disposal volumes.

CST’s new screening technology, to be showcased at Foodpro 2014 from June 22 to 25, was used by Golden Circle to replace a previous plant with 1.0mm screening capacity. The new installation features a 0.5mm rotary screen, complete with compactor.

Designed, supplied and installed by CST, the rotary drum screen solution allows improved and greater removal of solids from the wastewater, with considerably better solids capture, says Michael Bambridge, Managing Director of CST Wastewater Solutions.

Mr Bambridge explains that the compact new high efficiency system also allowed the removal of a tall existing structure and hoppers, making solids handling more accessible for the plant operator, improving operational efficiency and enhancing OH&S benefits by reducing solids handling. The compaction unit also reduces, by up to half, the volumes of solids to be transported.

The all-stainless construction including base frame and the fully enclosed design for OH&S odour and aerosol control advance rotary drum screen technology while enhancing durability, hygiene and serviceability.

Key features of CST’s rotary drum screen system include non-lubricated chains and non-metallic drive sprockets; upgraded running wheel design; no mechanical parts in contact with screened solids; corrosion resistance; ability to handle high fat and grease loadings; self-cleaning design; and optional wedgewire slots or perforated holes screening.

According to Mr Bambridge, the new rotary drum screen has a low investment cost, as well as low operational and maintenance costs. CST’s wide-ranging in-house experience also allows custom-designed machines to be supplied if required.

CST’s rotary drum screens are typically recommended for diverse industries including general food processing (vegetables, fruit, coffee, starch processing), beverages (beer, wine, juice, soft drinks), slaughterhouses and abattoirs, tanneries, pulp and paper mills, textile plants, and plastic manufacturers among many more. Municipal treatment plants also use the screens for fine screening of raw sewage, pre-MBR (membrane bioreactor) screening, and sludge thickening.
