Wastewater producers are seeking more cost-effective wastewater treatment methodologies designed to meet increasingly restrictive municipal discharge criteria. A dual goal is reducing their domestic water demand through recycling as the cost of water continues to rise. Effective but relatively inexpensive wastewater treatment systems that fit an individual industrial process can be readily installed. PL Garment Finishers is a blue jeans wet processing/finishing plant based in Dublin, Georgia, processing over 30 000 pieces per day. They nominally produce approximately 600 gpm of wastewater, operating approximately 120 hours per week. Their wastewater stream contains a significant amount of lint, pumice, pearlite, and dye. In order to meet local discharge criteria, they asked Kemco Systems to design a wastewater treatment system to meet a number of PL's design specifications and integrate seamlessly with the plant. The result was an Inclined Plate Clarifier (IPC) that has been successfully operated at flow rates up to 1100 gpm. The engineering term used to describe an individual physical waste treatment methodology is unit operation. An IPC is an example of a unit operation. Separation efficiencies using IPCs can be quite high, as the example in this article will show.
