Abstract

This study uses an ammonia waste water treatment system using 6 lanes and uses a batch-continuous system with electrolysis. Ammonia liquid waste content before and after electrolysis was analyzed using the Nessler method and analyzed using the Spectrophotometry method at a wavelength of 460 nm. Ammonia liquid waste with ammonia content can be used between 18,000-22,000 ppm used as a test sample. The results of this study indicate that the decrease in ammonia concentration every time is directly proportional to the amount of strong current and the number of electrode cells applied. The difference in number, by using 1 pair of cells can reduce 49.19%, 3 pairs of cells by 67.89%, and 5 pairs of cells by 85.08%. In the variation of electric current, 1; 5; 10; and 15 amperes produce 34.03%, respectively; 55.99%; 67.68% and 83.28%. On variations in the influence of the flow rate of 250; 500; 750; 1,000; and 1,250 mL/minute resulting from a decrease in the concentration of ammonia is relatively the same, i.e. concentrations between 82 to 84%. The rate of decrease in ammonia concentration at the liquid level reaches 85.08% by using a variation of 5 pairs of electrode cells with a strong current of 15 amperes. The flow rate used is 250 mL/minute, the electrolysis process is carried out for 8 hours. The modification of the wastewater treatment system by using this electrolysis method is feasible for ammonia liquid waste treatment.
