Treatment Plant Cleans Up Mining Contamination, Produces Clean Water

ABSTRACTThe clean water supply system network on Lengkang Kecil Island was developed in 2019. A small portion of the community's freshwater comes from harvesting rainwater and dug wells, which are only obtained during the rainy season. The primary source of clean water used by the community comes from underwater pipelines with a daily discharge of 0.86 l/sec. The water supply of the Lengkang Kecil Island community is 74.3 m3/day, with 146 House Connections (HCs) and to serve public facilities such as elementary schools, primary health centers, and mosques. Hydraulic evaluation of clean water distribution using EPANET 2.0 software on flow velocity shows the lowest rate of 0.29 m/s and the highest of 1.21 m/s. The lowest pressure value in the distribution system is 6.94-6.96 m and headloss units in the range 0.08-0.25 m/km. These three criteria are still within the distribution network design criteria (feasible). A carbon footprint can be calculated from each activity from the analysis of the evaluation of clean water distribution networks. The most massive emissions came from pumping activities with 131 kg CO2-eq, followed by emissions from wastewater 62.5 kgCO2-eq. Further research is needed to determine the quality of wastewater and the design for a centralized wastewater treatment plant (IPALT) to improve Lengkang Kecil Island residents' living standards.Keywords: Lengkang Kecil Island, water, EPANET, carbon footprintABSTRAKJaringan sistem penyediaan air bersih pada Pulau Lengkang Kecil dimulai pada tahun 2019.

The Cost

This article reviews a new approach to fuel cells that turns wastewater into clean water and electricity. Operating and maintaining a wastewater treatment plant is a costly proposition. New fuel cell technology that generates power while it cleans wastewater may offer a way to make clean water more available for developing and industrialized nations. Increasing the power output is another major goal. While the first-generation device did not provide much power, a more recent iteration of the microbial fuel cell generates enough electricity to power a small fan. The first generation of the design proved that it is possible to generate fuel and clean water using wastewater as a medium. Logan and his team are working on ways to boost the power production of the microbial fuel cell, lower the cost to produce it, and transition it from the lab to a mass-production device.

Penerapan metode daur ulang air limbah yang dilakukan oleh PT CHN juga dapat menguntungkan secara ekonomi yaitu dengan dapat mengurangi pemakaian air WTP Jababeka sebesar 77,5 %, sehingga mampu menghemat biaya pengeluaran pembelian air sebesar Rp 99.187.652 /bulan. Abstract - PT. Chemco Harapan Nusantara (PT CHN) requires large amounts of clean water to be used as process water in production process activities. The total need for clean water for all production processes is 10.450 m3 / month. PT CHN can produce products of value from the use of clean water. Besides that, it also produces waste water which can pollute the environment. The purpose of this research is to apply the wastewater recycling method at PT CHN so as to reduce adverse environmental effects due to waste water disposal and generate economic savings, especially during the Covid Pandemic19. The application of this method is done by treating wastewater in a wastewater treatment plant, then reprocessing the water in a clean water treatment plant. The processed water obtained is then distributed to each of the clean water user production processes. The method used in this study is to interview and survey directly on site and then analyze the results of research with data analysis techniques coding, entering, cleaning, display and analyzing. Based on the results of the study showed that the application of the wastewater recycling method is able to convert all wastewater into clean water that can be used for the production process, so it does not pollute the environment. This is evident that in the process all wastewater is put into a wastewater treatment plant which is then treated again at the WTP and the treated water from the WTP is reused as process water. The application of the wastewater recycling method conducted by PT CHN can also be economically profitable, namely by being able to reduce the use of Jababeka's WTP water by 77,5%, thereby being able to save on the cost of water purchase expenses of Rp 99.187.652 / month.

Clean Water

Water is one of the important components of human life or other living things. With the increasing number of residents, the need for clean water has also increased. However, this increase in demand is not offset by the availability of clean water due to the lower quality of water produced by the water treatment plant. Therefore, it is necessary to do alternative water treatment so that clean water needs can be sufficient. One method of processing clean water that can be done is the Jar test method. This study aims to determine the effect of coagulant dose addition on water quality parameters including pH, turbidity, TDS and total hardness of the Manisrejo City Madiun well water sample after water treatment. The research method is carried out through three stages, namely the preparation stage, the instrument analysis stage and the experimental stage. Where the type of coagulant used is Poly Aluminum Chloride (PAC). From the research that has been done, the optimum PAC coagulant dose is 43 mg / l. The conclusion obtained in this study is that the greater the coagulant dose added to the water sample, the smaller the pH value, the value of turbidity, the TDS value and the total hardness of the water sample.

A treatment plant using conventional biological treatment combined with hydroponics and microalgae is constructed in a greenhouse in the area of Stockholm, Sweden. The treatment plant is built for research purposes and presently treats 0.559 m3 of domestic wastewater from the surrounding area per day. The system uses anoxic pre-denitrification followed by aerobic tanks for nitrification and plant growth. A microalgal step further reduces phosphorus, and a final sand filter polishes the water. During a three week period in July 2002 the treatment capacity of this system was evaluated with respect to removal of organic matter, phosphorus and nitrogen. 90% COD removal was obtained early in the system. Nitrification and denitrification was well established with total nitrogen reduction of 72%. Phosphorus was removed by 47% in the process. However, higher phosphorus removal values are expected as the microalgal step will be further developed. The results show that acceptable treatment can be achieved using this kind of system. Further optimisation of the system will lead to clean water as well as valuable plants to be harvested from the nutrient rich wastewater.
