Effluent Treatment Plants
There are a vast array of effiuent treatment technology available. Industrial waste water treatment covers the mechanisms and processes used to treat waters that have been contained in some way by industrial or commercial activities prior to its release into the environment or its re-use.
Pollutants are substances that have the potential to have negative effects on the natural environment, to cause damage to infrastructure or harm to human health.
Pollutants in industrial waste water contain a mixture of organic and inorganic substances, in solution, as solids in suspension, as a separate phase (e.g. starch or clay).
Some pollutants are toxic and/or harmful and can have a direct impact on the receiving environment e.g. heavy metals, mineral oils, solvents, strong acids and alkalies.
|Preliminary||Removal of large solids such as rags, sticks, grit and grease that may damage equipment or result in operational problems||Physical|
|Primary||Removal of floating and settle able material such as suspended solids and organic matter||Physical and Chemical|
|Secondary||Removal of biodegradable organic matter and suspended solid||Biological and Chemical|
|Teritary||Removal of residual suspended solids/desolved solids||Phusical,chemical and biological|
