Paper Title
Automation On Zero Liquid Discharge Process In Digester Plant

Abstract
Abstract- Anaerobic Digestion (AD) is a biological process that happens naturally when bacteria breaks down organic matter in environments with little or no oxygen. It is effectively a controlled and enclosed version of the anaerobic breakdown of organic waste in landfill which releases methane. This project totally concern with digester plant and its automation in order to minimize labor cost and eliminate the hazards level. The automation is minimize the time require to monitoring the plant. There are many sensors are used for automation in digester plant such as limit switches, pressure gauge, solenoid valve, temperature sensor and ph detector . these all sensor is connected with plc(programmable logical circuit).the Plc monitor all the process automated whenever the signal get to it. And basically the process can monitor a single man, without affecting the plant, and its process.
