PLC & SCADA based automation of filter house, a section of Water Treatment Plant

Rajasthan is an arid state and hence making available drinking water is a government priority. Under Bhageri Ka Naka (Rajasthan) Rural water supply scheme, there is a transmission system of a capacity to produce and deliver 16.21 MLD of treated water in the clear water reservoirs near treatment plant. This water supply scheme is divided mainly into three sections namely: (1) Intake Pump House (IPH), (2) Water Treatment Plant (WTP) & (3) Clear Water Pump House (CWPH). Water Treatment Plant Section Involves: 1. Turbidity Measurement and Alum Dosing. 2. PH Measurement and Lime Dosing 3. Clarifloculator for Clarifying the Alum dosed and Lime dosed Raw Water 4. Filter House for further filtering the Clarified Water. 5. Chlorination This paper describes how automation of Filter House (section 4 of Water Treatment Plant) is done for this project using PLC & SCADA.
