TERTIARY TREATMENT
{"Image DocumentName": "TERTIARY TREATMENT", "Image ImageDescription": "Oxidation ponds can provide complete treatment and a sufficiently large oxidation may be the only treatment step for a small waste flow. When the rate of oxidation in a pond is too great and oxygen availability becomes limiting, the pond may be forcibly aerated by either diffusive or mechanical aerators. Such ponds are called aerated lagoons and are widely used in treating industrial effluent. 4. BOD may also be removed by activated carbon adsorption, which has the added advantage of removing some inorganic as well as organic compounds.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
