MBBR Wastewater Treatment Basin Sizing And Aeration Calculations

MBBR Wastewater Treatment Basin Sizing And Aeration Calculations

Wastewater treatment is very important for our environment and public health. Here, let’s explore the delightful world of MBBR wastewater treatment. MBBR systems use microorganisms attached to plastic media to eliminate organic material and pollutants from water, resulting in clean effluent.

These systems have become popular recently due to their efficiency and compactness in treating various types of wastewater. They can handle a high organic load and adapt to different conditions. That’s why MBBR systems are a favorite for industries, municipalities, and even residential areas looking for sustainable wastewater treatments.

The MBBR process involves specialized plastic media, which give a surface area for active microbial growth. When wastewater passes through the system, microorganisms attach to the media and form biomass. This biomass breaks down organic matter in the water naturally, leading to a reduction in pollutants.

An interesting part of MBBR technology is its origin. It was developed in the late 1980s by Professor Hallvard Ødegaard from the Norwegian University of Science and Technology (NTNU). Initially, it was called “biofilm carrier technology.” Through research and improvements, it evolved into the MBBR technology we know today. MBBR systems are now essential for any modern wastewater treatment plant.
