This research studied the factors that affect the efficiency of phosphate reduction in the wastewater of the washing process with CaCO3 and CaO produced from eggshell and mussel shell. The study found that the optimum condition for adsorption when using CaCO3 from eggshell is to adjust the pH to be equal to 10 take 15 minutes to absorb and add 1 gram of sorbent which can reduce the phosphate content by 25 percent and when changing the adsorbent to CaO the optimum condition for phosphate removal is to adjust the pH to 7 take 15 minutes to absorb and add 1 gram of adsorbent which can reduce the phosphate content by 24 percent. The optimum conditions for adsorption when using CaCO3 from mussel shell were to adjust the pH to 10 take 45 minutes to absorb and add 1 gram of sorbent which can reduce the phosphate content by 25 percent and when changing adsorbents to CaO the optimum condition for phosphate removal is to adjust the pH to 10 take 15 minutes to absorb and add 3 grams of adsorbents which can reduce the phosphate content by 24 percent. In addition when studying the adsorption of impurities in the wastewater such as conductivity turbidity COD and BOD it is found that the optimum reduction conditions can reduce the impurities of the parameters that mentioned above were 19.32 2.60 54.77 and 16.67 percent respectively. CaCO3 and CaO produced from eggshell and mussel shell can be used to absorb impurities in wastewater before releasing into natural water sources.

This research is a study on treatment of Water Dyes from textile dyeing industry by Advance oxidation process with Ozone and hydrogen peroxide (H2O2). In this study Ozone generators with a capacity of 1.0 - 3.0 mg/ hr. were used to study the appropriate factors for treatment with adjusting wastewater conditions (pH 3 pH 7 and pH 11) Ozone exposure distance 120 minute the initial COD concentration is 250 - 1000 mg/l. and adding hydrogen peroxide at 4 8 and 12 ml/l. For the study found that above mentioned factors have an effect on the efficacy of color and COD treatment which the experiment at pH 11 used to Ozone treatment and added 4 ml/l. of H2O2. It makes the highest COD treatment efficiency when compared to pH 3 pH 7 and added more H2O2. it doesn’t affect to the higher of treatment efficiency. In addition it was found that higher initial COD concentration decreased treatment efficiency which the experimental ability for COD treatment has highest value was 46 percent and the COD concentration was 250 ml/l In order that when COD concentration in synthetic color water was increased to 500 ml/l and 1000 ml/l. it was found that the COD efficiency decreased to 31% and 40% respectively. For the treatment of Water Dyes from textile dyeing industry by oxidation process with Ozone together with hydrogen peroxide (H2O2) at pH 7 will has the highest of treatment efficiency. However the consideration of suitability for pH configuration used to treat both color and COD should choose pH 11 because it can treat both color and COD that makes the waste water quality meet the standards required by law. In addition if we consider the effectiveness of turbidity and BOD found that the decrease of dirtiness tends to be in the same direction with COD both 2 parameters.

This research is to study the efficiency of treating wastewater from dyeing fabric by the ozonation process. By using rutile TiO2 coated plastic media to catalyze. Which uses O3 generators with a capacity of 2.62 - 3.10 g/hr. By studying the factors that affect the treatment efficiency of COD and color such as the pH of the water used in the treatment at pH 3 pH 7 and pH 11 the initial COD concentration of 100% 50% and 25% which have values in the range of 100 -320 mg/L. O3 exposure time 120 min. From the study it is found that the efficiency of reducing the impurities in wastewater by the ozonation process in the pH 11 state the COD concentration at 50% can reduce the COD. And the maximum color is at 33.3% and 90% from the 550 ADMI color intensity with a COD of 180 mg/L. For the study of the efficiency of reducing the impurities of wastewater by ozonation process together with 2 g. of TiO2/1 L. of wastewater in the condition of pH 11 concentration COD Beginning at 100% with the ability to reduce COD values And the maximum color is at 40% and 80% of the 270 ADMI color intensity with a COD of 190 mg/L. The amount of O3 suitable for treatment has an average value of 0.0374 g/min./10.5 L. of wastewater. The duration of O3 exposure in both processes has a similar approach to the efficiency of COD and color treatment when increasing the duration of O3 exposure.
