Abstract
The number of electroplating industries in West Java in Indonesia has increased rapidly which affects the amount of pickling and degreasing solutions used in the washing process. Generally, the electroplating industry disposes of its wastewater directly into the environment without treatment. The metal ions contained in the pickling and degreasing solution will accumulate in the environment which will eventually cause the washing water to become rich in dissolved metal ions. One of the wastewater treatment methods is adsorption. Zeolite from the adsorbent was applied in this study with variations in grain size and processing time. Electroplating wastewater is used to control nickel metal ion concentration. This study aims to study the effect of zeolite on the concentration of nickel metal ions, which are filled with the adsorption column using the circulation method. The column has a diameter of 3 inches, a height of 120 cm, and a discharge of 120 ml/min. The results showed that the nickel metal ion concentration decreased from 26.75 g/l to 12.93 g/l, decreased pH from 8.2 to 7.6, and decreased water conductivity from 1250 ohm-1 to 815 ohm-1.
