Screw Press
Dewatering screw press is used for efficient thickening and dewatering of sludge waters. Sludge waters are water, containing certain amount of suspended solids, these can be product of waste water treatment, food proccessing industry, chemical industry and other branches of human activity. Our dewatering screw press, which serves to thicken sludge water to 20% dry-matter content on municipal sludges and more for mineral/industrial sludges, can provide efficient desludging. In terms of quality, this equipment surpasses traditional sedimentation sludge removal and other technologies.
This dewatering/thickening screw press has been designed to be used primarily in wastewater treatment plants, but can also be used for thickening both industrial water and wastewater in food-processing operations.
The Dewatering Screw Press has a role in several industry sectors and is not just concerned with processing sewage. The sludge dryer system of separating liquid from solids is used in the paper industry where water is removed from cellulose fiber. In the chemical industry, screw presses are used in a variety of processes, including those used for synthetic rubber, hydrated polymer and sodium alginate. The food industry uses screw presses to extract alcohol from foods. It is also used to separate water from waste food to convert to animal feed. With a focus on the environment and the use of natural resources, maximizing the use of wastewater is crucial, especially in regions where there is low rainfall. A dewatering screw press minimizes the amount of solid volume that requires disposal too, which ensures landfill and other waste systems are optimized. If a dewatering screw press has been installed, it eliminates the need for the cost of sedimentation tanks, as the secondary sludge is thickened by the equipment after the process.
Advantages:
- The area required by Screw Press is very less compared to other equipments used for same. There is high space saving if we go for screw press technology.
- The Screw Press is a fully automatic system thus, resulting in easy and efficient operation as compared to conventional Sludge Handling process such as Filter Press
- The screw press has a very long equipment life as compared to Filter Press. There are no frequent replacement of Filter cloth as in Filter Press
Benefits :
- low energy use
- simple installation and operation
- 0.5-2% sludge at inlet, 15-20% sludge at outlet
- low noise and vibration levels
- wide use applications
- automated mode
- affordable spare parts
- low transport weight
- economical operation also for smaller WWTP (already from 500 equivalent)
- high quality workmanship, manufactured in the Czech Republic
