Ultra-fine screens for new applications
Our development of extremely fine screens for the separation of very fine particles permits new wastewater treatment applications for screens.
Reliable separation of hair and fibrous material is necessary for efficient performance of membrane bioreactors.
Another application for ultra-fine screens is river and sea outfalls. Reduction of the COD/BOD loads from such outfalls is becoming more and more important for the protection of the receiving water bodies.
HUBER ultra-fine screens are able to remove undegradable and degradable, inorganic and organic material at the same time.
Chemical precipitation, coagulation and/or flocculation can be added for further improvement of the screening efficiency. Addition of such chemicals converts dissolved substance and colloidal particles into separable aggregates that can be removed. Suspended solids can be reduced by up to 95%, COD/BOD by up to 65% and phosphorus by up to 60%.
Improved environmental protection is achieved by application of this new technology at reasonable costs.
For many regions with insufficient wastewater treatment, if any at all, ultra-fine screening is a quick and affordable first step in the right direction.
