摘要： Composition and method of use for tannin based environmentally benign polymeric coagulants are disclosed. Tannin based coagulants are copolymers of naturally occurring tannins and a cationic monomer. One embodiment of the present invention provides for a composition, of a tannin based polymeric coagulant which is comprised of N,N-(dimethylaminoethyl) methacrylate (MADAME) polymerized using t-butylhydroperoxide and sodium metabisulfite. The resulting polyMADAME is converted to hydrochloride and then blended/reacted in an aqueous medium with tannin to obtain a homogenous poly(MADAME)-tannin composition. The method of use comprises adding an amount of the composition effective for the purpose of clarifying oily wastewater from food and beverage, steel, automotive, transportation, refinery, pharmaceutical, metals, paper and pulp, chemical processing and hydrocarbon processing industries.

摘要： Disclosed is a process and apparatus that uses multiple stages or unit processes to treat wastewater, such as distillery spent wash which may be molasses spent wash (MSW). The stages include one or more of anaerobic digestion, chemical treatment, electrocoagulation, aerobic treatment, physical separation, and RO or adsorbent based treatment. A chemical treatment for the effluent from an anaerobic digester treating MSW is described. In an electrocoagulation step, a stable cathode is used to also provide electroflotation and hardness precipitation. Aerobic biological treatment and physical separation may be provided by a membrane bioreactor.
