    摘要: A process for preparing a liquid slurry of bentonite which comprises the steps of charging a reactor vessel with between about 25 to about 75% of water by weight. The water is heated to a temperature range between about 50.degree. C. to about 95.degree. C. The reactor vessel is charged with between about 0, 1 and about 10% of sodium salt of silicic acid by weight and with between about 15 to about 35% of bentonite by weight. The reactor vessel is also charged with between about 10 to about 30% of a polyacrylate by weight.

    摘要: The present invention provides a method for conditioning food processing waste prior to mechanical dewatering with the use of environmentally friendly coagulants and flocculants. The method of the present invention comprises treating these waste waters with an effective amount of a vinylamine polymer including from about 1 to about 100 mole percent vinylamine and from about 1 to about 99 mole percent of at least one monomer selected from the group consisting of amidine, vinylformamide, vinyl alcohol, vinyl acetate, vinyl pyrrolidinone and the esters, amides, nitriles and salts of acrylic acid and methacrytic acid. In an embodiment, the method of the present invention includes the further step of adding an effective amount of at least one flocculant to the food processing waste. The flocculent effectively agglomerates a portion of the colloidal organic solids into suspended solids.
