The proposed automation solution for wastewater treatment plant involves the use of a series of small control systems that run the facility, PLC (Programmable Logic Controller) continuously monitor the operation of pumps, closures and other devices, collect and execute commands coming from the higher levels, while programmable controllers (PLC) are used to control various processes based on the data and the built-in algorithm. According to the given specifications, a control panel was created in a suitable SCADA software for the control and monitoring of wastewater treatment facilities, the communication between the SCADA application and local PLC controller is necessary. A program that provides the appropriate behavior of the valve placed at the entrance and the control of the pumps was written in a ladder diagram. The alarm and monitoring system is of the highest importance. It covers the most significant facilities of the wastewater treatment plant pumping stations, reservoirs and supply lines and shows whether the plant as a whole works well. If something unexpected happens – such as a failure or a malfunction of a vital facility – the system should register and alert the staffs who work there.

Electric Discharge Machining (EDM) is an electro-thermal non-traditional machining process having a widespread applications in automotive, aviation, miniaturized scale frameworks industries etc. EDM process is governed by thermoelectric vitality between anode (workpiece) and cathode (tool wire). EDM shoulders a fantastic part in the improvement of practical things with more dependable quality affirmation. Enhancing the material removal rate, surface finish and diminishing the tool wear rate and dimensional variation were paid exceptional attention in EDM. Generally copper, brass and graphite are utilized as tool (cathode) materials. In this experimental research work, SS 317 grade steel is machined in EDM by varying input factors and optimized the process using Full factorial method. Copper and brass electrodes were utilized as tool material on SS 317 steel which is oil hardened, non-shrinking steel. These steels are used for fine parts such as taps, hand reamers, milling cutters, engraving tools and intricate press tools which cannot be machined easily after hardening.Keywords
