Abstract

Reverse Osmosis (RO) drinking water management can be the best solution to overcome the clean water crisis in Pulau Pinang. RO is a process that allows water to pass through a semi-permeable membrane and separates most of the dissolved salts, organic matter, bacteria, and other substances from the water to produce clean water. The use of the RO method in drinking water management is one of the best alternatives to overcome the clean water crisis, especially in the Pinang Island area with surface water sources that are not dominated by freshwater can ensure the availability of sustainable clean water. However, RO-based drinking water management is water demineralization, so further management is needed such as remineralization to meet mineral standards in drinking water.

Abstract

This research highlights the potential of anionic polyacrylamide as a main treatment agent for liquid waste from educational laboratories, particularly in the removal of copper ions. This study using experiment with varies the concentration of anionic polyacrylamide with 3, 5, and 7% weight per weight. The initial concentration of copper in liquid waste was very high ranging between 600 mg/L. The findings indicate that the application of anionic polyacrylamide in wastewater treatment significantly reduces the concentration of copper ions, especially in wastewater from educational laboratories. Specifically, anionic polyacrylamide, at a concentration of 3% w/w, effectively removed almost all copper ions from the wastewater found in analytical chemistry laboratory and also achieved the quality standard of treated wastewater for copper parameter. The pH of the treated wastewater is critical in determining the overall effectiveness of the treatment, with a higher pH resulting in more effective coagulation of copper ions. The effectiveness of the treatment is influenced by the pH of the wastewater and the concentration of the polyacrylamide used. Further studies are needed on other types of heavy metals that can be coagulated using this method in order to gain a more comprehensive understanding.
