Sewage treatment plants in fermenting and beverage industries.Peer-reviewed article

B. FRANZ

Prior to evaluating the efficiency and specific features of various purification system the author describes principal kinds of waste water which differ from one another in the percentage of harmful impurities to be removed and in the biochemical consumption of oxigen. The authors interpretation of oxigen consumption is far from being conventional and is based both on the results of his own research works and literature. Then the author compares several purification system-paying special attention to the so called " intensive method " base on the principle of continuous fermentation. The method has been developed at the VEB PKM ANLAGENBAU works end is characterized by slight dilution of heavily infested water and kinetic utilization of high concentration potential. Owing to intensive oxygen feeding the efficiency of the method is roughly ten times higher that of conventional systems using activated sludge. To compensate for oxygen consumption, maintain necessary concentration and remove foam the installation incorporates a centrifugal suction-type aeration unit designed by the author. In near future standard technology will be elaborated for various categories of plants. The author estimates also roughly capital investments stressing that they depend on the amount on sewage, concentration of harmful components and required purification rate.
