MICROORGANISMS & CHEMICALS WORKING TOGETHER
Microorganisms, particularly bacteria, play a pivotal role in chemical waste treatment plants. These microbes help break down various waste materials into harmless byproducts, reducing pollution and making water suitable for reuse. Initially, wastewater passes through screens and grit chambers to remove solids. To accelerate bacterial activity, some treatment plants pump sewage sludge into aeration tanks, where bacteria multiply rapidly.
While bacteria can't eliminate all chemicals, pre-treatment and other techniques are used to address specific contaminants. The benefits of using bacteria in sewage treatment include cost-effectiveness, energy efficiency, reduced sludge formation, and the removal of nitrogen and phosphorus from wastewater.
Different types of bacteria are employed in these processes, including aerobic and anaerobic bacteria, nitrifying and denitrifying bacteria, and phosphorus-accumulating and sulfur-reducing bacteria. Each type has a unique function in breaking down waste and controlling the concentration of specific elements.
To summarize, harnessing various bacterial species and sustainable recycling methods enhances the efficiency of waste breakdown in treatment plants, making the process safe, energy-efficient, and environmentally sustainable. Plants can also use chemicals to improve effluent quality before releasing it back into nature.
