Industrial Applications using Wastewater Treatment using PLC
Journal Title: GRD Journal for Engineering - Year 2018, Vol 3, Issue 0
Abstract
Many industries have a need to treat water to obtain very high quality water for demanding purposes. Industrial wastewater treatment covers the mechanisms and processes used to treat waters that have been contaminated in some way by commercial activities prior to its release into the environment or its re-use. This is most commonly done by manually controlled devices. With the development in technology, this process can be automated. In this paper, we have described the automated industrial wastewater treatment process using PLC technology. This process involves treatment in two phases namely, primary and secondary stages. Here the steps are made automatic using sensors and timers of a PLC. The wastewater is first primarily treated where solid wastes settle down and lighter debris and grease rise to the surface to form a crust. In the primary stage, the working is based on the principle that when the water level drops enough so that the Low Level float switch is off (down), the PLC will open the valve to let more water in. Once the water level raises enough so that the High Level switch is on (up), the PLC will shut the inlet to stop the water from overflowing. The secondary stage involves biological treatment using the same principle. This treatment gives a new dimension for the automation of such manual processes.
