Study of HAZOPs in the Screening Unit of the Industrial Gas Wastewater Treatment Plant

The filtration is the final stage of industrial gas wastewater treatment for clean water generation. Filtration an operation separating solid and liquid materials by filter medium. In process driving force such as pressure difference gravitation or rotary power cause feed to flow. parameters in need be monitored controlled because deviation abnormality will operating failures. This condition requires a more in-depth identification so that risks failures can minimized. HAZOPs method identify hazard caused using guide words. Steps research consisted early survey, literature study, filling worksheet determine study node, deviation, parameter, guideword, risk evaluation, control. results show there were four potential deviations from three which flow, pressure, temperature. Risk values analysed medium low. Recommendation system are adding alarm, valve, changing regularly, scheduling routine maintenance.
