| Abstract |
An evaluation of the treatability of unsegregated, unequalized, and unneutralized wastewaters from a side-leather tanning industry utilizing the hair pulping process by primary and secondary biological and gravity separation in clarifier-thickeners, whereas the secondary treatment method employed aerated ponds and final clarifiers with the capability of recycling biological solids. The system was operated over a wide range of detention times, with and without solids recycle, and nutrient (phosphorus) addition, and during seasonal variation representing mean monthly air temperature variations from -14C to 30C. The removal efficiencies were related to loading relationships as well as temperature variations. The secondary treatment effluent was reused in the beamhouse operations under test conditions to evaluate the effects of water conservation practice on leather qualities as well as to determine the buildup of conservative substances in the wastewater effluent such as chloride. |
