Product Description
Movable Screw Dewaterer:
1. Structure
This screw dewaterer mainly consists of overlapping fixed rings and moving rings, and screw axis across the rings. Moving rings rotate with screw axis to clean the pore in filtering zone to protect the system from blockage.
2. Dewatering Principle
The gap between fixed rings and moving rings, together with the screw pitch of screw axis are narrowed down gradually from thickening zone to dewatering zone across the filter cake discharge outlet. The sludge is transferred to dewatering zone after thickening zone by gravity, and is fully dewatered under the internal pressure produced by back-pressure board in discharge outlet.
3. Wide application
This dewaterer served as a precedent for the direct dewatering of low concentration (2-35g/l) sludge from oxidation ditch,
There is no need to use thickening tank and storage tank,
It does not make any stinky smell.
4. Little blockage & Auto Cleaning
The main body of the machine has the function of self-cleaning,
Less water is required for cleaning and washing (only 40 l/h),
The dewaterer is suitable for oily sludge treatment.
5. Design Cost Reduction
There are many types and series of the products. The most suitable type can be selected based on different treatment scales, which can avoid usage of a large machine for the small amount of sludge treatment. The dewaterer is compact, in which the thickening and dewatering are integrated. The machine itself has auxiliary devices, such as operational panel and sludge flocculation reaction trough, etc., which is highly compatible with corollary equipments and convenient for design.
6. Construction Cost Reduction
A) The small-scale dewaterer can fit local situation easily to save the construction cost and the space used for the dewaterer placement;
B) This dewaterer has a function of sludge thickening. There is no thickening and storage unit needed, which can reduce the construction cost and the total area requirement for the wastewater treatment system.
7. Maintenance & Management Cost Reduction
A) The dewaterer is durable in use with low frequency maintenance. (Only minority of components may need to be replaced after long-term usage);
B) A small-scale design of the dewaterer provides a easy learning for the operators.
