The activated sludge process is one of the most widely utilized waste treatment technologies. It is used not just in home systems but also in big sewage treatment plants. A bio-zone chamber and a settlement chamber are the two basic components of these systems. The activated sludge process is more than just a wastewater treatment system. It's an advanced waste disposal method that is used in sewage plants and other environments where large amounts of liquid require treatment. It's also an extremely efficient way to handle waste — even the most toxic substances can be treated using the activated sludge process.
