摘要： A method and apparatus for increasing dewatering efficiency of a solids-laden liquid stream in a wastewater treatment facility, whereby a liquids-solids: stream is pumped into a mixing apparatus in a closed-channel liquid flow conduit configuration, where the liquids-solids stream is intensely mixed with air and polymer in a mixing zone created by an adjustable flow restriction device, performing similar to a venturi to Increase the velocity, agitation, and turbulence of the liquids-solids stream internal to the mixer, where the introduction of air and polymer to the stream is introduced independent of mixing energy. Compared with current methods and apparatuses to mix polymer with solids-laden wastewater, the present method and apparatus requires less energy, where it enables the addition of air independent of mixing energy, and it creates a zone of mixing with greater mixing efficiency via increased turbulence.

摘要： The invention relates a method for dewatering of biological sludge. It comprises addition of a flocculant to a biological sludge, which comprises an aqueous phase and suspended solid organic material, flocculating and dewatering the sludge. The flocculant comprises a polymer composition, which comprises a cationic crosslinked first polymer, which is selected from crosslinked polyamines, and a cationic second polymer, which is a polymer obtained by polymerisation of (meth)acrylamide and cationic monomers, the second cationic polymer being polymerised in presence of the cationic first polymer.

摘要： The present disclosure is generally related to the separation of liquids from solids and for the recovery of solids and/or liquids from slurries. In some embodiments, liquids are separated from solids by applying a reduced pressure. In some embodiments, slurries are flowed by applying a pressure gradient. In some embodiments, an apparatus is provided that comprises a channel, an inlet, an outlet, and one or more ports. One or more ports may be constructed and arranged to apply a pressure differential and/or a reduced pressure to the channel. Such systems and methods may, in some embodiments, facilitate continuous manufacturing of solid products.
