Abstract
The present disclosure relates to recycling automotive phosphate rinse water. An apparatus and method is disclosed for treating process water containing phosphate. The apparatus may include a process water line. The process water line may be in fluid communication with a sample process water line. The sample process water line may be in fluid communication with a dilution line. The sample process water line, the dilution line, and a phosphate analyzer may be in fluid communication with a diluted process water line. The apparatus may also include a chemical additive feed line in fluid communication with the process water line downstream from the sample process water line.
