Dewatering Screw Press (DSP)
Food & Beverage
South Australia
BACKGROUND
A meat processing plant in Adelaide wanted to reduce its disposal costs for the sludge from its Dissolved Air Floatation (DAF) plant. Following a technical review of different sludge dewatering processes a Dewatering Screw Press (DSP) was identified as the best solution in the application. A trial dewatering screw press was installed to build a business case for the capital expenditure.
Following a successful 4-week trial of a Dewatering Screw Press (DSP), including customised polymer optimisation, the business bought the plant to immediately capitalise on savings from greatly reduced disposal costs.
SOLUTION
Dewatering Screw Press (DSP) treating 100 kg/hr of DAF feed sludge at 10% dry solids (DS) produced dewatered cake at 18.6% DS.
MAK WATER KEY SOLUTIONS
- Plug and play dewatering equipment
- Simple automated solution with low operator input
- Easily integrated to existing process
- Polymer optimisation for site specific sludge producing maximum DS cake
- Robust and low energy equipment
RESULTS AND BENEFITS
- Successful pre-purchase pilot. Captial investment risk mitigated with trial. Success quickly justified the purchase.
- 18.6% DS cake. Dry cake with high solids content achieved, enabling business to instantly save on sludge disposal costs.
- Fast delivery. Hire plant delivered and commission on site within 2 working weeks
- Fast Pilot to Production Timeframe. Once pilot plant established successful results, recommissioning it into production was done within a week.
- Technical Support. Support and assistance during commissioning and into production was seamless and allowed production to continue with minimal
- Reduced operating costs. Sludge disposal costs reduced dramatically with payback period of less than 6 months.
