Abstract - In this paper, we present a technical
water level are both controlled simultaneously. Due to this, handling the product manually becomes a tedious job, and human errors can result in the processing taking longer than expected, so automation plays an important role in this process. The automation of the process reduces time consumption, increases repeatability and accuracy, and eliminates human errors.
communication in the automation industry which explains the technical aspects of automation control system in water treatment system development, improving management levels, and enhancing process efficiency. Today, most of the water treatment plants in the world are used for water conservation projects, which are enabled by automation control systems, to provide safe, continuous, high-quality water to municipal clients and for multiple applications. The water treatment process is necessary for a variety of processes other than industrial processes (such as gardening, washing, etc.).In India, there are over 50 environmental acts that must be followed by industries. The government requires companies to treat their waste water and to reuse it for other industrial processes, such as gardening. In a water treatment plant, various processes have to be monitored and controlled regularly. Therefore, handling the plant manually becomes a tedious job. Manually pacing a plant becomes a tedious task thus PLCs automate the process to eliminate human error, increasing efficiency and accuracy. This paper describes ways to implement PLCs into existing real-time models of a water treatment plant. PLCs allow for the continuous monitoring and control of parameters, as well as efficient monitoring and control.
1.1 PROBLEM STATEMENT The aim is to implement PLC to the existing model of Water Treatment Plant, which has a capacity of one m3 per hour, i.e. in one hour, we can obtain 1,000 liters of purified water.
1.2 OBJECTIVE
In the industrial sector of water treatment plants, there has been a steady increase in the demand for high quality, greater efficiency, and automated machines. There is a possibility of errors occurring with measurements and at various stages that involve human workers and also a lack of features on microcontrollers. As such, continuous monitoring and inspection at frequent intervals are necessary. In the industrial sector, PLC applications are extensively used to automate repetitive processes such as furnaces, bottle filling plants, elevators, and nuclear power plants. A good example is the automation of water treatment plants using PLC, which is one of these industrial automation applications. Here automation plays a vital role, as high pressure control is a crucial task. There are many fields where pressure and Impact Factor value: 7.529
To improve reliability. To save precious resources.
a)Boiling: Purification of water in this way is one of the earliest methods known to mankind, and it can be used in almost any situation, even in an emergency, without special equipment. Ideally, the water should be allowed to boil for three minutes to kill off any harmful bacteria.

To improve efficiency.
b) Distillation: Water is also purified by distillation, which involves the use of a distilling tank. In this method, water is poured in the bottom of the tank, where it is heated until it reaches its boiling point. A portion of the tank is used to create steam, which is collected there for collection. Once it has condensed, the steam becomes pure water, which is then stored until it is needed again.
A. c) Reverse Osmosis: A membrane separates two parts of a two-part tank that is used in this process to purify water. |
