Methods and apparatus for treating water and wastewater include the step of flowing a suspended solids stream generally upward through a sludge blanket region of a cloth disk filter vessel, thus forming a partially treated effluent composition and a solids-enriched sludge blanket. The partially treated effluent composition is allowed to...

12/29/11 - 20110315636 - Soluble anion exchangers from hyperbranched macromolecules
Novel macromolecules for filtering contaminants from water and non-aqueous solutions. Molecules such as polyethyleneimine (PEI) may be functionalized, cross-linked, and/or quaternized to improve their binding capacity or selectivity with particular water contaminants such as bromide, nitrate, and sulfate. The macromolecules may be either recyclable or non-recyclable, and may be recovered...

09/22/11 - 20110226701 - Enhancing sedimentation performance of clarifiers/thickeners
Some mineral processing plants encounter difficulties in dewatering pulps using clarifier/thickener (C/T) equipment due to a layer of fine particles, air bubbles and chemicals formed at the top of the liquid in the thickener. Such layers are very stable and form a cap on the C/T. The dewatering performance of...

09/15/11 - 20110220581 - Hydrophobically modified polyamine scale inhibitors
Hydrophobically modified Si-containing polyamines are useful for treating scale in industrial process streams.
