Excerpt from Disposal and Purification of Factory Wastes or Manufacturing Sewage
During the past fourteen years the wastes from three tanneries have been experimented upon. The first tannery investigated was engaged in preparing and tanning sheep skins. The daily volume of the waste varied from to gallons, and was composed of a thick, offensive liquor varying in color as different aniline dyes were used. The amount of organic matter present was large and in an advanced state of putrefaction. It seldom contained any substance of a character to check bacterial action and was, therefore, easily nitrified. The sludge was at times great in volume and rich in fats and nitrogenous matters. A filter was constructed at this tannery, containing 2 feet in depth of sand Of an effective size of millimeter, over gravel underdrains; and sewage, made up Of a mixture of the waste liquors from all the proc esses carried on at the tannery, was first applied to it on Sept. 27, 1895, at an average rate of gallons per acre daily. During a large part of its period of operation, however, the rate was gallons per acre daily, but even at this rate the filter became clogged quickly by matter in suspension in the waste.
The following analyses Show the character of the liquor as applied to and Of the effluent from this filter during its period Of operation.
