Companies such as General Environmental Science Corp. and Polybac Corp., which market specialized bacterial cultures for treating industrial wastes, claim that the cultures improve the operation of activated-sludge, trickling-filter, and lagoon-treatment plants, and provide faster system response to startups, variable and shock loads, and cold weather. The effectiveness of the special cultures is difficult to verify and has been questioned by environmental experts, including R. L. Raymond (Suntech Inc.) and E. Barth (EPA), although E. Stigall (EPA) believes they may aid plant recovery after upsets. A study by Business Communications Co. has predicted that the market for such additives will reach $50 million by 1987, from $5 million in 1979. The use of such cultures in Exxon Corp.'s 1 million gal/day activated sludge system at the Benicia, Calif., oil refinery improved the system's performance by 32Vertical Bar3<, resulted in faster unit startups and more stable operation, and reduced foaming. J. T. Baker Co. has used successfully two broad-spectrum dried additives for ammonia removal and hydrocarbon degradation at its 3 million gal/day secondary treatment plant at Phillipsburg, N.J.
