TYPE OF INDUSTRY – Dairy products
MODEL OF DEHYDRATOR – MDQ-353 C
START OF OPERATION – 2018 December
Issue
The customer had an interest in reducing sludge disposal costs in their industrial wastewater treatment plant by obtaining lower maintenance costs and lower energy consumption. The plant treats industrial wastewater from a nearby cheese factory and generates about 15,000 gallons of activated sludge from their MBR system per day.
Solution
On-site pilot tests were carried out, using mobile dewatering unit MDQ-201, to find the best dewatering technology. According to the test results Esmil offered sludge dewatering technology based on Multi-disc Screw
Press Dehydrator MDQ-353 C.
