Abstract
The use of water in industrial activities is a problem that needs to be given strong attention to always be used as a benchmark for water quality, especially in the industrial activities of PT Petrokimia Gresik. To optimize the use of large amounts of water from the activities of the company PT. Petrokimia Gresik, it is necessary to implement water efficiency policies. In previously treated water processing, the pH was neutralized using NaOH, which is relatively expensive. Therefore, to save costs and run the water efficiency program owned by PT Petrokimia Gresik, it is necessary to carry out research on the efficiency of ZA II factory liquid waste as a substitute for NaOH. The effectiveness of ZA II fertilizer wastewater as a pH neutralizer can be determined by testing the pH, TSS and PO4 levels. The method used in this research is neutralization. The variation used is a mixture of neutralized water, NaOH and ZA II waste water. The NaOH used was 0.1 ml; 0.3 ml; 0.5 ml. Meanwhile, the sample used was 100ml. Based on the research results, it is stated that ZA II fertilizer wastewater can increase pH levels due to its alkaline nature, from 6 to 8. Cost savings calculations were also carried out if NaOH was not used, resulting in cost savings of Rp. 98,800,000/month. Based on the research results, it is stated that ZA II fertilizer wastewater can increase pH levels because it is alkaline.
