TICA manufactures automotive air-conditioning compressor parts and generates several types of process wastewaters. CWS upgraded the system by replacing dissolved air flotation with ultrafiltration. UF is a proven technology for handling metalworking oily coolant waste streams. Wastewater streams were rerouted to utilize existing tanks for additional equalization capacity, and an upgraded pH adjustment system using carbon dioxide was installed.
