Abstract

Personal Care Cosmetic Products (PCCPs) are used on the exterior of the body, such as the skin, nails, hair, lips, external genitalia, teeth, and oral membranes. Greywater from a bathing activity is a significant contributor to domestic wastewater quantity. The greywater contains residual substances from the rinsing process of body care products. Aim: This study will focus on the characteristic and the specific pollutant load of greywater generated from the usage of shower gel. Methodology and Results: The characterization and specific pollutant loads are conducted based on artificial greywater which is made from three brands of shower gel which is diluted in tap water. The greywater from body cleaning activities has a pH value in the range of 7.26-7.33; total phosphate in the range of 1.71-3.09 mg/L; the value of NTK total Kjedahl nitrogen in the range of 2.45-4.03 mg/L; total COD in the range of 380.97-506.16 mg/L; dissolved COD values in the range of 310.92-393.68 mg/L; TSS value in the range of 62-229.50 mg/L; and TDS values in the range of 283-376.67 mg/L. The specific pollutant load generated from shower gel usage in greywater are 0.012 g TP/person/day; 0.016 g TKN/person/day; 2.14 g Total COD/person/day; 1.59 g dissolved COD/person/day; 0.94 g/person/day for TSS; and 1.48 g/person/day for TDS. Conclusion, significance, and impact study: The Greywater from shower gel usage contains physical and chemical constituents that can promote environmental deterioration. The finding of this research will provide useful information for domestic wastewater management and system design, especially for urban areas in Indonesia.

Abstract

Indonesia is a country that has considerable coal reserves with coal resources of 149.01 billion tons. One of the problems of coal mining is turbidity. The turbidity is caused by the excavation of the open pit mine so that rainwater contact with the main wall. So that mud is formed, which can increase turbidity levels. The concentration of Total Suspended Solids (TSS) due to this phenomenon reaches 5,400 mg/L. Aim: This study aims to set aside TSS by electrocoagulation processing method using a batch system with eight pairs of iron electrodes arranged monopolarly. Methodology and Results: Comparisons using statistically independent t-tests showed that there was no significant difference between the iron and aluminium electrodes in the pH parameter. Conclusion, significance, and impact study:There were significant differences between iron and aluminum electrodes in the parameters of TDS and TSS. In the measured TDS and TSS parameters, the electrocoagulation process using iron electrodes has a higher value than aluminum electrodes. In the TSS removal, there is no significant difference between the two electrodes (iron and aluminium).

Abstract

Solar desalination technology has been one of the effective solutions to tackle the problem of water scarcity. A number of studies have been conducted at our water research group to determine which variable influences the quantity of distilled water produced by an independent solar desalination unit. Aims: This study was aimed to design and optimize a novel solar desalination unit and field-tested using the best variable from the previous studies. Methodology and results: Variables used from the previous studies were evaluated to obtain the best values for each parameter, those are: glass cover inclination, gap distance between water and glass cover, insulation thickness, water depth, and water mass flow rate. Those best values were then implemented in the optimized basin design, delivery mechanisms, evaporation techniques, and heat isolation methods. The optimized design can generate up to 2,778.2 mL/m2/8hrs of distilled water with an efficiency of 23.35% in preliminary test, and was field tested at Batukaras Beach, where it produced up to 902 mL/m2/8hrs with an efficiency of 13.56%. Conclusion, significance and impact study: Meteorological parameters and environmental conditions are important factors that greatly affect the performance and productivity of the desalination unit. The relative humidity is inversely proportional to the volume of distillate water, where the smaller the value, the greater the amount of distillate water that can be produced, and it has significant impact on the productivity of the prototype. The quality of the distillate water produced still needs improvement on the parameters of pH, turbidity, and total coliform.
