Abstract | Operation of a secondary-tertiary treatment facility for combined domestic and pet food manufacturing industrial wastewaters at the City of Tualatin, Oregon, was studied for 16 months. The study demonstrated the feasibility of automated tertiary treatment for small communities treating a combined domestic and industrial wastewater at a reasonable cost. The tertiary system consisted of a four step process: (1) alum and polyelectrolyte coagulation, (2) flocculation, (3) inclined tube sedimentation, and (4) mixed media filtration. The total capital cost of the facility was $245,800. Based on total annual cost, the cost of treatment at the design conditions was $0.42 per 1000 gallons processed and $0.19 per pound of BOD removed. (Modified author abstract) |
