| Summary: | Textile industry is one of main industry in Malaysia. There are a lot of activities in textiles industry such as dyeing process where a lot of water is required. Quality of water is main issue in this process to produce quality product or fabric. A study was done at Ramatex Textiles Industrial Sdn. Bhd. raw water treatment plant to see efficiency of ferum and manganese removal. Water supply, which contains high concentration of ferum and manganese, will affect the fabric quality such as yellowish stain. For Ramatex permeable limit for Ferum and Manganese concentration are 0.3 mg/L and 0.5 mg/L. This study was concentrate at three methods to removed Ferum and manganese by using potassium permanganate, aeration and combination of potassium permanganate and aeration method. Quality of river has concentration of Ferum between 0 mg/L to 6.5 mg/L, and for manganese between 0 mg/L to 2.6 mg/L which are excess with Ramatex quality limit. From the study, it show that efficiency of Ferum removal by potassium permanganate is between 22 % to 100%. Aeration method has efficiency from 94 % to 100% and combination of two methods between 70 % to 100%. Efficiency of Manganese removal by potassium permanganate is between 8 % to 64.5%. Aeration method has efficiency from 0 % to 13% and combination of two methods between 0 % to 100%. Chemical consumptions also reduce about 55% for potassium permanganate by using combination of two method without reduce water quality for production usage. |
