The results of the implementation of community service, obtained the results of the Tuntang River Water Quality Test, namely, Iron: 0.496 mg/L, COD: 301 mg/L, Chloride: 7.30 mg/L, manganese: 0.502 mg/ L, the river water filter scheme uses a system with 3 settling tanks and 2 mixed bed tubes. The shelter uses a 3300 ml Toren with a tower as high as 3 m from the ground. There are 17 families who have received clean water supply from the new source

Terlambatnya Proses Pendinginan Muatan Gas Polymer Grade Propylene di Kapal LPG/C Coral Millepora

The LPG Carrier is one of the ships that carries liquid gas cargoes below -48o C. The LPG Carrier has facilities in the form of a reliquefaction plant that uses seawater as a coolant for gas cargo. Therefore, the reliquefaction plant has an important role in the smooth loading and unloading process. If one of the reliquefaction plant particles is damaged, of course the cooling process of the polymer grade propylene gas load will be hampered. The purpose of this study is to describe the problem in the cooling process of polymer grade propylene load. The authors conducted research using a qualitative descriptive method through an interview approach, direct observation of the object of research, and supported by paper-based documents or photos. Based on the results of the study, it was found that the causes of delays in the cooling process of polymer grade propylene gas cargo, namely the influence of weather, sea water content, clogged sea water filters, clogged condenser tubes, and condenser shell tube leaks.

Recent Developments in Nanomaterials Based Adsorbents for Water Purification Techniques

Currently, most advanced technologies employ nanomaterials due to the modern tailor-made properties these materials exhibit compared to their bulk counterparts. Nanomaterials have attracted researchers around the globe in the last few decades due to their unusual properties due to the presence of a greater number of carriers at the surface, which affects the chemical and physical properties of these materials. Ensuring pure drinking water for domestic purposes is the biggest challenge in current times. Industrialization is increasing with time due to human needs. The extensive use of fertilizers to enhance agricultural productivity has hazardous effects on the ecosystem. Water pollution will significantly impact living beings on the land and aquatic beings, followed by terrestrial, aerial flora, and fauna. In a world full of technologies, there are many methods to purify water (water filters, RO purifiers, etc.). Still, nanotechnology plays a vital part in purifying water on a large scale. Nanotechnology methods came up with new materials and analytical techniques that can treat the by-products that are toxic to the environment. Heterogeneous photocatalysis used with metal oxide nanostructures causes no harm to the ecosystem. Nanomembranes and Nanostructures will play an active role by acting as a trap for many Nano pollutants. This review presents nano cellulose, nanocarbon tubes, and nanomembranes used in water purification and analytical techniques by addressing the current economic water purification techniques.

Inequality in India: Through the Lens of Differences in Water Quality

India is ranked as the worst country in the world, in terms of number of people lacking access to safe water. This study examines the socio-economic inequity of India through the lens of privileged Indian respondents’ perceptions of the water quality accessible to communities of different socio-economic status. To address this aim, a survey was conducted to measure the level of social awareness around this issue among privileged Indian respondents with regards to their ratings of the safety of the water in three different communities: their own, the underprivileged, and India as a whole. Respondents rated their water quality to be the highest, followed by India as a whole, and then the underprivileged. The main reasons they offered for their ratings were: the government’s failure to set up an adequate infrastructure for piping water without polluting it and the inability of the underprivileged to afford water filters in India. Despite the gravity of the health problems that can ensue from the lack of access to safe water, the lack of accountability for the government, and apathy from the privileged residents, can be attributed to the deeply entrenched discrimination in India, which is founded upon its caste tradition and its pursuit of the capitalist agenda in the ‘90s. Therefore, it is vital that the Indian government and people take responsibility for providing safe water to all by: increasing awareness amongst all communities; provision of water filters for all, and the eventual changing of the piping system in the long term.

Physico-Chemical Studies of Ground Water and Filter Water Samples in Ramanagra Taluk, Ramanagara District, Karnataka, India

The main objective of our study was to convey the importance of water to mankind. We can survive without food for several weeks, because our body will gradually switch to using stored fat and protein to make its energy, but cutoff of water supply leads to death of mankind within few days. Around two third of our body is water. On average we need 2.4 liters of water on each day to keep us healthy that’s the only reason people spend so much of money on water filters that will remove harmful impurities. In the early ages before the existence of filters, tubehole water was one of the sources of drinking water in our taluk. But according to the analysis in the recent years we found that this tubehole water had contamination of fluoride (2). In the later years many research scholars took initiative for the removal of fluoride in the tubehole water. This initiated us to make a comparative study to assess the quality of both filter and tubehole water found in the region of Ramanagara Taluk. Unfortunately through our research we found that some of the water samples were unfit for drinking. Water samples of few areas were selected for qualitative analysis of water. Water samples were analyzed for examination of pH, alkalinity, acidity, conductivity, total dissolved solids (TDS), total hardness, calcium, chlorine, magnesium, nitrate, fluoride and sulphate. It is important to monitor the physical properties of both filter and tubehole water, as it is a early warning signal that something is happening to water.
