Some have leaves that float on the water surface, while others grow completely under water. The oxygen content is also affected by certain factors such as the rate of photosynthesis by aquatic plants; the metabolic rates of aquatic organisms; and the sensitivity of organisms to toxic wastes, parasites, and diseases.
To treat the upland reservoir with pH of 5. Later, when this was seen to cause serious water pollution, step by step mechanical wastewater treatment plants, biological treatment for the degradation of organic substances, and tertiary treatment for the removal of nutrients were The first stage is separating solid waste from the water.
This statement may lead you to believe there is no need for concern, but there is a big pink elephant in the room. Major sources of BOD include leaves and wood debris; dead plants and animals; animal manure; effluents from pulp and paper mills, wastewater treatment plants, feedlots, and food-processing plants; failing septic systems; and urban storm water runoff.
For example, low concentration addition of Krebs cycle intermediates, glucose, amino acids and vitamins, such as alanine and nicotinic acid, to the sludge can accelerate the rate of oxidation of specific components.
Advanced treatment technologies include a wide range of physical, chemical, and biological methods, with nutrient removal rates of 90 percent or greater depending on the specific technology.
Organic farming is the ultimate source to reduce such pollution and to protect the water bodies as well as all living organisms and the environment.
