Development of pH value detection sensor for water to detect and automate water neutralization process
(International Journal of Research and Analytical Reviews(IJRAR), 2022-06) Ganesh Ram, V.; Aravind, D.
Water pollution is one of the severe problems that have crippling effect on public hygiene. This paper proposes a suitable method to detect and perform corrective measures using sensing components to aid maintenance of water quality. In the money conservative market like India, less importance is given for public hygiene and there is a general myth that any quality monitoring system would be costly and complex in its operation. Water is a universal solvent and in nature, it is never totally pure. No matter how for isolated, it is from sources of contamination, it will always have some chemicals. Gases or minerals in the air, soil, or rock are dissolved by the water. Some dissolved materials give water its characteristic taste, and “pure water” is generally considered to be flat and tasteless. Our main purpose is to identify and treat to remove unwanted constituents in the water and to make it safe or fit for a specific purpose in industry or domestic applications. We are making our system portable and compact, to process only upto a certain limit as it is a prototype. The development of pH electrode plays a major role for this research. Resistance is measured for various levels of water, where non-linear resistance identifies the pH value. Each individual liquid has a different resistance level for the pH. As resistivity is directly proportional to the current & voltage. The methodology presents a self-developed pH level indicator that measures pH level of the water. The end process gives quality water for people usage and indicates the same with its auto monitoring system.
Reduction of engine emission into the environment through effective operation of catalytic converter in proportion with pollutant
(SPECIALUSIS UGDYMAS / SPECIAL EDUCATION, 2022) Aravind, D.; Ganesh Ram, V.; Thangalakshmi, S.; Balaji, C. P.
The discharge of harmful impurities put into air which creates unwanted effects to the environments and people. Inadequate engine combustion is one of the causes for air pollution with the emission of CO, HC, NOx, SOx soon. Whenever there is an incomplete combustion takes place huge volume of CO gas is released. If the fuel includes a high Sulphur concentration, the Sulphur in the petroleum combines with the oxygen during the combustion process and releases SO2. The unburnt hydrocarbon is due to incomplete combustion and NOx (Oxides of Nitrogen) are leads to the formation of uninflamed gas in the exhaust with nitrogen. Hence, rigid norms of effluence emissions are enforced as safety measures which has made exhaust gas aftertreatment systems important. In order to reduce the engineemission, the current method is the use of catalytic converter. This paper discusses an effective system for improving presentation of the catalytic converter by using an embedded controller in proportion with emission.
SBR Sewage treatment plant automation using PLC and SCADA
(Advanced Engineering Science, 2022-10) Aravind, D.; Ganesh Ram, V.; Thangalakshmi, S.; Balaji, C. P.; Govindarajan, Rajendran.; Rajkumar, Perumal.
Today's never-ending industrial expansion and the sharp rise in urban pollution have led to environmental and water contamination. The industrial sewage water gets mixed with streams, ocean and ponds etc. that causes several ailments in living things. Proper treatment of sewage can prevent these problems. Sewage treatment is the process of removing contaminants from industrial/domestic wastewater. Physical process (such as filtration, sedimentation and distillation), chemical processes (such as flocculation and chlorination) and biological process (slow sand filters or biologically active carbon) are used to remove contaminants so that water becomes safe enough to get released into the environment. By using these sewage processes we can not only avoid the diseases but also we can recycle the industry wastewater (sewage process) for further uses (garden, car cleaning, etc.). There are conventional methods for sewage treatment, which occupies more spaces as well as involve higher constructive cost. The activated sludge process is modified by the "fill and draw" Sequencing Batch Reactor (SBR). The complete treatment procedure takes place in one tank as opposed to separate tanks for each process. The benefits include less expensive plant construction due to tank reduction and smaller footprint compared to alternative treatment options. This paper aims to monitor and automate various stages of sewage treatment carried through sequencing batch reactor. In general, industrial automation refers to the use of technology for process control in a variety of operations, including chemical and petrochemical, power, iron, and steel, food and beverage, waste water treatment, and other plants. One of the main needs that reduces the need for labour is plant automation. Currently, SCADA systems and programmable logic controllers are widely employed in industry. In order to improve the efficiency of the sewage treatment process, the application of PLC is investigated in this study.
