Abstract

Industrial Liquid Waste is liquid waste generated from the effects of industrial processes. The petroleum industry produces liquid waste that can have a negative impact on the environment because petroleum processing produces
several substances that are classified as hazardous and toxic (B3). The content of heavy metals and organic chemicals can be contained in the liquid waste. Among the organic chemicals contained in the liquid waste of the petroleum industry is
ammonia or NH3. Treatment of liquid waste containing ammonia with good and strict techniques is very important because liquid waste will be discharged into the
environment. Ammonia content is limited in liquid waste according to PERMEN LH No. 19 of 2010 the quality standard of ammonia in liquid waste is 8 mg/L. This research is an experimental study, namely research conducted to determine the
effect of additional materials in this study, the dose of zeolite and contact time on the treatment of the research object with the adsorption method. The object of this
research is the Inlet Treated Water sample from the WWTP Pertamina RU IV Cilacap unit with an initial ammonia value of 117 mg/L. This study aims to
determine the appropriate dose and contact time of zeolite in absorbing ammonia. The variation of the dose used is 500; 1000; 1500; 2000 and 2500 mg/L, while the
contact time used was 20; 40; 60; 80 and 100 minutes.
The results showed that the variation of the optimum absorbed ammonia dose at a dose of 2500 mg/L, had a percentage decrease of 90.42% with an ammonia yield of 11 mg/L. while the variation of the optimum contact time of adsorbed ammonia within 80 minutes had a percentage decrease of 84.93% with ammonia yield of 17 mg/L. Both variables have a fairly high percentage of
reduction in ammonia levels but have not been able to meet the ammonia quality standard threshold of 8 mg/L.
