Protection of natural water resources like lakes from the onslaught of hazardous municipal wastewater is often a challenge particularly in the cold regions. For treatment of enormous quantity of municipal wastewater, biological treatment is normally adopted but high COD (Chemical Oxygen demand) of such wastewater turns biological treatment slow and difficult. At low temperature environment, effective treatment of such municipal wastewater becomes extremely difficult due to weakened microbial activities. The present study was carried out with a hybrid approach comprising chemical treatment and membrane separation under psychrophilic conditions. Well-known Fenton's treatment was adopted under response surface optimized conditions that helped recovery of nitrogen and phosphorus nutrients as value-added struvite fertilizer or magnesium ammonium phosphate (NH4MgPO4•6H2O). The optimal COD removal was found to be 96% at a low temperature of 15 o C and pH of 6.3 using Fe 2+ /H2O2 ratio of 0.10 and of H2O2 1.9 g/l with reaction time of 2 h. Downstream purification of the struvite-free water by microfiltration and nanofiltration largely fouling-free flat sheet cross flow membrane modules ultimately turned the treated water reusable through reduction of dissolved solids, conductivity and salinity.

Ground water is defined as water that is in the ground and is water that moves and is present in the spaces between the grains of soil that make it up and rock crevices, where the initial part is called layer water and the latter is called fissure water. Water is one of the natural elements that are needed in the life activities of living things, especially humans. The purpose of this study is to assessing the value of groundwater revenues and determine of optimum rates in Makassar City. Data analysis method used is the analysis of groundwater value by referring to the Minister of Energy and Mineral Resources Regulation No.20 of 2017 concerning Guidelines for Establishing Groundwater Revenue Value and the marginal cost pricing method. The results showed that the average revenue of groundwater in Makassar City was IDR.690,276,939.35 with an average tax of IDR.138,055,387.87. The value of groundwater is quite high when compared to the revenue value of groundwater that has been determined by the Makassar City government at this time. The results of determining the optimum rates obtained for the user group 1 is IDR.9,661.96 per m3 per month, the user group 2 is IDR.13,973.63 per m3 per month, the user group 3 is IDR.10,866.67 per m3 per month, and the user group 4 is IDR.4,255.56 per m3 per month. Whereas the beneficiary group 5 has a higher average groundwater utilization cost when compared to the PDAM water rates. The results of research can become policy basis of the Makassar City local government in determining the value of groundwater.
