Abstract |
The report contains two studies. In the first, high concentrations of sodium chloride and sodium sulfate were observed in a town with a high concentration of textile mills. Sludge digestion was very poor. A toxic synergism between sodium chloride and sodium sulfate (sulfide) was hypothecated. Data indicated a marked reduction in gas production through a bi-sulfide ion effect upon the first stage microorganisms. The methane organisms appeared to starve rather than suffer a toxic effect from an accumulation of first stage by-products. Inert salt concentration had very little effect. In the second, synthetic surfactants were studied. It was found that biodegradable synthetic detergents now used in place of salt to cause dye uptake require long periods of aerobic treatment because of interference by foam in floc development.
