The textile industry is the largest industry contributing to the wastewater pollution and is a concern for the environment today. This pollution occurs when wastewater from the textile industry discharges the water into the river and it will affect both aquatic and human life. There are several ways to overcome this pollution problem but the current method is very expensive and its effectiveness depends on the colour of the dye. In this research, activated carbon of rice husk was used as an adsorbent to remove the methyl red dye from the wastewater. To detect the effectiveness of rice husk, two materials were used which were raw rice husk and also activated carbon to remove methyl red dyes from wastewater. There are four parameters used to investigate the optimum level which are the effect of initial dye concentrations ranges from (2 mg/L-10 mg/L), contact time (20-100 minutes), pH (2-10) and adsorbent dosage (0.5-2.5 g). The percentage of dye is calculated and recorded to see the comparison between raw rice husk and also activated carbon of rice husk. The results show that the rice husk can be used as a potential adsorbent to remove methyl red from the waste water.

Wastewater is residual water of industrial activities and domestic wastewater that is derived from daily activities of human life related to water usage, such wastewater should not be discharged into water bodies if it has not met the standards based on the regulation. Oil and grease contained in the water bodies will form a layer on the surface because the density of oil is lower than the density of water. The layer of oil and grease will block the entry of sunlight and cause the inability in the photosynthesis process of aquatic plants. The textile industry facilitates canteens within the company which operates daily at 11.00–13.00 Western Indonesian Time, resulting in the domestic wastewater from the canteen kitchen activities. The purpose of this study was to determine differences in the thickness variations of activated carbon to reduce oil and grease levels using modified grease traps on the canteen wastewater at PT. Sipatex Putri Lestari. The type of study used was categorized as a field experiment with a pretest–posttest research design. The population of the study was the entire canteen wastewater of PT. Sipatex Putri Lestari. The sampling technique used the time composite method. The univariate analysis of the study showed the average number of decreases in oil and grease levels in the treatment as 12.32, 15.98 and

Garments plays a vital role among the basic needs of human life, hence there are lots of demand and production of dyestuffs every year to colour the fabrics. In the dyeing process 10 to 20% of the dyes are wasted as effluent. Dye laden wastewater is treated by biological or chemical treatment which is found to be inadequate and expensive. In this study, an attempt has been made to prepare an activated carbon from agro-waste based material, Corn Cobs which are abundantly available in Tamil Nadu. Base activation of Corn Cobs was done with ZnCl2 solution for 12 hours and carbonized at 350º C for 2 hours. A kinetic experimental study was carried out for Congo red dye removal. In the preliminary studies both the Commercial Activated Carbon (CAC) and Corn Cobs Activated Carbon (CCAC) with various initial adsorbate concentration of 50, 65, 75, 100 and 125 ppm were considered. For further studies on the effect of various parameters such as the contact time and adsorbent dosage, initial concentration of adsorbate was chosen as 65 ppm. The other experimental parameters such as temperature and initial pH were kept at 27±0.5°C and 6.8±0.2 respectively. The experimental results of both CAC and CCAC were compared. The CCAC showed a removal of 97.8% at an adsorbent dosage of 1.2 g, whereas the CAC showed a removal of 98.1% at a dosage of 0.3 g. The result shows that CCAC has abundant potential for the removal of dye.

Textile industry is one of the major contributors either in terms of employment or economies.This industry has provided variety of daily necessity such as sources of yarn and clothing.Extensively use of dyes in this textile industry has created water pollution. The serious problemhappened when the daily water usage is from the untreated effluents which are discharged directlyinto water bodies. However, the disposed dyes into environment can be treated with adsorbentssuch as activated carbon via adsorption process. In this study, Parkia speciosa (petai) pods werechosen as the raw material from agricultural waste to produce activated carbon. Activated carbonwas prepared from two different chemicals and application of four different carbonization time.Two parameters studied in the experiment are initial dye concentration and contact time. From theresult, 100% of methyl red was removed by the activated carbon impregnated with zinc chloridesolution at 1 hour carbonization time. The optimum time and initial concentration of dye was 30minutes and 10 ppm respectively with the percentage removal of 100%. Thus, this result couldcontribute some knowledge on the use of alternative adsorbent from agricultural wasteimpregnation with specified chemicals in treating textile industrial wastewater.

South Kalimantan is one of the textile industry producers, which is Sasirangan industry.The traditional fabric-making process involves chemicals as the production process. Sasirangan liquid waste contains pollutants that do not meet the requirements for disposal into the environment, including cadmium (Cd). Adsorption process is an effective method to reduce heavy metal concentrations in liquid waste. This study aims to determine the potential of rice husk activated carbon in adsorbing Cd metal from  sasirangan liquid waste and to analyze the effect of stirring speed on the adsorption process. The rice husks that had been carbonized were then activated chemically and physically. Chemical activation process was carried out by adding chemical compound HCl which was immersed for 24 hours. Furthermore, it was physically activated in the furnace for 45 minutes at 4500C. In case to get optimum result, the effect of stirring speed on the adsorption process was studied. The stirring speed determines the rate of adsorbent and adsorbate contact time. The higher the stirring speed, the higher the decrease in Cd content because adsorbate absorption process by  adsorbent is getting better. The greatest decrease in Cd concentration was by carbon that had been activated  with a stirring speed of 90 rpm where the remaining Cd content in the sample was 0.018 mg / L.
