Most, if not all chemical industry generates waste water from its processes. This waste water is often pre-treated and then disposed to water courses as agreed with the appropriate authorities. The focus of attention has usually been on the environmental hazards of waste water. This paper illustrates that process safety hazard from waste water treatment can also pose significant risks. Five serious events are described associated with the pre-treatment, storage, re use or treatment of waste water from chemical production. They are from four different countries and from a variety of businesses. These include one detonation, two confined vapour cloud explosions, one over-pressure from gas evolution and one thermal runaway and fire. In particular, often waste water sumps span an entire plant and have developed explosions over extensive areas. The paper describes the events, lessons learned and some methods and procedures that can be used minimise the risks.
Key words: Waste water, Chemical processing, hazards and risks
