Automation of Water filtration plant
Project Area of Specialization Electrical/Electronic EngineeringProject SummaryReverse Osmosis (RO) Water Filtration Plant is a machine that is capable of removing the contaminants from water by using pressure which forces the water molecules to pass through a semi permeable membrane while flushing out the unwanted particles. Attaining the required Total Dissolved Solvents (TDS) parameter is a major challenge due to various complications. The main idea of this project is the development of an entirely automated water filtration system. The second goal is to develop and test the real-time performance (removal of the contaminants and achieving the desired TDS) of the system designed. The reference point will be the Product tank of the system – relying on its feedback the system will operate accordingly. The sensors will measure the various parameters in real-time and the controllers will be implemented on a Programmable Logic Controller (PLC) and a Human-Machine Interface (HMI).
Reverse osmosis can remove many types of dissolved and suspended species from water, including bacteria and is used in both industrial processes and the production of potable water. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side.
Project ObjectivesThe main objectives of the project are as follows:
- Development of a testbed based upon water filtration plant.
- Development of machine to machine communication.
- Development and testing of the PLC controller for filtration process.
- Development and achieving the desired quality/parameters of the filtered water.
- Monitoring and control of water treatment using an HMI.
- Interfacing various sensors and controllers to automate the filtration process.
To implement this whole filtration process, first of all a hardware needs to be implemented following a software program. In this program it must be taken into account that the goal of the project is open-loop and closed-loop control. The Filtration Plant can be operated not only automatically but also manually by a PLC and an HMI respectively using TIA portal dashboard while depending on the feedback from the Level sensor of the product tank. The Level sensor then autonomously activates or de-activates the filtration process via the feedback loop. An Ethernet based network configuration using Siemens Programmable Logic Controller (PLC) S7-1200 will allow the Filtration Plant to communicate with the Human-Machine Interface (HMI). The whole process will be monitored and also be able to controlled manually through the HMI.
