Abstract
Increasingly stricter specifications for plant effluents, may now require tertiary treatment to meet water soluble chemical oxygen demand and biochemical oxygen demand limits. This paper describes a system in which the effluent water from a tall oil plant is treated and recycled to the process instead of being treated and discharged.
