The dyeing industry both of business size and household size where the remaining water from the dyeing process is dumped into pipes and flows into natural water sources causing sewage problems. Therefore a column type wastewater treatment system has been developed by using a filtration system along with an adsorption system. The materials used to treat the wastewater from dyeing are gravel sand charcoal from wood and activated carbon from coconut shell. The study was conducted on the synthesis activated carbon from coconut shell using for color and molecules adsorption. The amount of activated carbon from coconut shell was varied at 200 400 600 and 800 g applying with filter media and other adsorption materials taking 1 hour to treat the wastewater from dyeing. The parameter using to measure water quality consisted of color value pH suspended solids conductivity turbidity value COD and TKN to indicate the water quality before and after treatment evaluating the efficiency of the wastewater treatment system. The best ratio that can treat the color is the formula containing 800 g of coconut shell activated carbon. It was able to treat the color equal to 5.94 SU or 99.43 percent compared to the wastewater before treatment.

The purpose of this research was to investigate the use of soaked black bean water and to add value to it otherwise it is considered as colored waste water. The soaked black bean water was analyzed for phytochemicals and dyeing process was carried out silk cotton and polyester fibers. Dried black beans were soaked in water ratio 1:1 for at least 12 hours. The dyeing process involved soaking the fiber in soaked black bean water at 100o for 30 min. to determine the type of fiber staining and color fastness. Results showed presence of Anthocyanin Anthraquinonoid Terpenoid Saponin Tannin and Flavonoids in soaked black bean water. It was found that dye could be absorbed by silk fabric in an acidic condition. The shade appeared red-brown at L*44.17 a*16.88 and b*20.13 color strength was 6.19 and ultraviolet protection was blocked more than 97.5 percentages as UPF 50+. Moreover the color fastness grading in crocking property was very good to excellent (CF 4-5) good washing fastness (WF4) and moderate fastness in the presence of light (LF 4). In conclusion soaked black bean water can be used for dyeing for silk fabric and enhance UV protection.
