disadvantages of biological wastewater treatment
How does biological wastewater treatment affect aquatic animals?
Biological wastewater treatment produces some unwanted microorganisms that produce gases and bad odor. This treated effluents containing water cannot be released into water bodies as it can cause a change in physicochemical properties of water, which ultimately leads to a decrease in the aquatic animal population.
What are the limitations of wastewater treatment?
Although various methods for wastewater treatment have been explored in the last few decades but their use is restrained by many limitations including use of chemicals, formation of disinfection by-products (DBPs), time consumption and expensiveness.
What is biological treatment of wastewater?
The treatment of wastewater subsequent to the removal of suspended solids by microorganisms such as algae, fungi, or bacteria under aerobic or anaerobic conditions during which organic matter in wastewater is oxidized or incorporated into cells that can be eliminated by removal process or sedimentation is termed biological treatment.
