Bod and cod ratio
Webthe ratio of BOD:COD is less than 0.1, which means the presence of high organic matter and is it difficult to biodegrade, and it can be toxic (Andrio et al.,2024) The lowest ratio of BOD:COD for water to be easily biodegradable is 0.4 (Lee & Nikraz,2015) and that the best value is greater than 0.5 (Samudro & Mangkoedihardjo,2010). ... Web– High BOD/COD is indirect indicator of the organic content – Ammonia is inorganic and creates an oxygen demand • As it is converted to nitrate . Aerobic Biotransformation • Dissolved oxygen is consumed in the process of convert organic matter into inorganic matter
