A method of preparing and separating biopolymers and biopolymer fractions is useful for wastewater treatment applications from sewage sludge. The method comprising the steps of disrupting the bacterial cell walls of bacteria present in the sewage sludge by at least 75% to release the intracellular contents of the bacterial cells and separating the biopolymers from any contaminants present.

Method for the preparation of biopolymers

A method and related apparatus for the removal of excess water from sludge, the method comprising the steps of: (1) fermenting the sludge at a temperature in the mesophilic temperature range, (2) maintaining the fermenting sludge for a predetermined period under a hydraulically quiescent condition to achieve phase separation, (3) separately removing the solid phase and liquid phase and (4) feeding the solid phase to the digester for conversion to biogas.

Production of volatile fatty acids by means of mesophilic fermentation of sludge

Process for reducing the level of unsaturation in a polyether polyol having an oxypropylene content of at least 30% by weight calculated on the total amount of oxyalkylene units in the polyol and having a number average equivalent weight of at least 1000 by subjecting the polyol to ultrafiltration.
