Overview of MBBR Technology
What is MBBR Technology?
MBBR technology is a highly effective and innovative approach to wastewater treatment. It utilizes a biological process to break down organic pollutants in water, making it safe for discharge or reuse. The technology is based on the use of small plastic carriers, known as biofilm media, which provide a surface area for microorganisms to attach and grow.
