Outflow of water from a pulp or paper mill. Government regulations restrict the impact of effluents on the receiving waters with respect to solids, oxygen demand, toxicity and color. Mills control these factors by re-using or recycling water used for the various processes and by treating it in their own plants before discharge.
Waste liquid discharge from the paper-making process, usually including a small amount of suspended solids and dissolved chemicals. Biological effluent treatment plants at paper mills neutralise the effluent so water can be returned to the environment and effluent solids can be re-used as a soil conditioner.
Waste material being discharged into the environment, either treated or untreated. Effluent generally is used to describe water discharges to the environment, although it can refer to stack emissions or other material flowing into the environment.
Sewage, water, or other liquid, partiallyor completely treated or in its natural state, flowingout of a septic tank, subsurface wastewater infiltra-tion system, aerobic treatment unit, or othertreatment system or system component.
(1) Something that flows out or forth, especially a stream flowing out of a body of water. (2) (Water Quality) Discharged wastewater such as the treated wastes from municipal sewage plants, brine wastewater from desalting operations, and coolant waters from a nuclear power plant.
(Effluent) Residual fluid of agricultural, industrial or urban origin, treated or not, released directly or indirectly into the environment.(Translated from Dictionnaire de l'environnement. Conseil international de la langue française, 1992.)
