BIO MEDIA


The first MBBR process for municipal wastewater treatment was put into operation in Norway in the early 1990s. Today, with more than 200 municipal installations, the MBBR is one of the most well documented biological solutions for treatment of municipal wastewater. Which is very flexible and versatile technology, the bio media process can be designed for different municipal applications and levels of treatment. And typically applicable mode is divided two different types as below
