A Method of treating sludge prior to dewatering by mixing with the sludge a cationic metal in the form of an iron or aluminum slat along with a cationic polymer. The addition of the iron or aluminum salt substantially reduces the amount of polymer required for acceptable dewatering, thusly significantly reducing the cost of the dewatering process. The method is enhanced by subjecting the prior digested sludge to mesophilic aeration prior to the cationic metal salt and polymer being added.

An improved process for sludge treatment includes anaerobic digestion followed by post-mesophilic aerobic and/or anoxic digestion. The first anaerobic step may be performed under either mesophilic or thermophilic conditions. The subsequent aerobic/anoxic digestion may be performed using either simultaneous, sequential or pulsed aerobic and anoxic conditions. An apparatus for performing the improved sludge treatment may be one digester for performing the anaerobic followed by aerobic/anoxic digestion. Alternatively, the system for performing the improved sludge treatment techniques may be at least two digest reactors.

A cooking process which demonstrates improved cooking efficiency of foodstuffs, improves the quality of such food and enhances the safety of food for consumption by mammals, especially humans. The process utilizes a treatment of foodstuff with an aqueous ozone solution combined with a cooking process to provide a synergistic effect on the killing rates of microorganisms as well as a reduction of the level of microorganisms on and in such foodstuffs. The method comprises sanitizing/disinfecting the foodstuff using an aqueous solution containing an effective amount of ozone, which comprises forming an aqueous solution of ozone, and contacting the foodstuff with the aqueous solution, and subsequently subjecting the foodstuff to a cooking process. The foodstuff is generally contacted with the aqueous solution for a time sufficient to substantially sanitize or disinfect the foodstuff. Optionally, the foodstuff may be packaged before or after the cooking process. The use of an aqueous ozone treatment process for foodstuffs, in conjunction with a cooking process provides a multi-technology approach to reducing the level of microorganisms associated with foodstuffs. The process therefore allows food processors to reduce the amount of cooking needed, i.e., temperature and/or time of cooking, with a resulting enhancement in food quality and safety.

The present invention is a foamable alcohol having at least one active ingredient. The active ingredient can be a prescription or non-prescription drug or medication. It either works on the skin or is absorbed transdermally and works on the body. Alcohol, such as ethyl alcohol is combined with a fluoro-surfactant, at least one active ingredient and water. Optionally, inactive ingredients can be added. The fluoro-surfactant reduces the surface tension of the alcohol allowing it to be foamed without reducing the effectiveness of the alcohol as a carrier for the active ingredient or the efficacy of the active ingredient(s). The inventive mixture foams when dispensed as an aerosol or pumped through a foam pump. The pump or other dispenser doses the alcohol. The foam is easy to apply, and liquefies as a user smears it on a surface.
