Compact biological solutions to solve the challenges of municipal wastewater

Municipalities all over the world are faced with increased wastewater challenges. These include assuring environmental quality of the receiving water bodies, securing bathing water quality, protecting drinking water resources, and closing the loop by recycling used water for irrigation or as drinking water. 

Plants may now have to remove suspended solids, some organic material, nutrients and micropollutants.  

Cities continue to grow, leaving less space for extending capacity of existing plants or building new ones to meet more stringent effluent quality. This leads to increased demand for reducing Noise and Odor emissions and the optical appearance of municipal wastewater treatment plants. Climate change demands solutions with a low carbon footprint.

AnoxKaldnes developed MBBR as a solution to upgrade existing primary settlers with Biological treatment within existing volumes.

Today, many plants based on activated sludge need to be upgraded either to treat more water or to incorporate nitrification or nutrient removal.

We developed Hybas to solve these issues, and for situations where stringent effluent quality has to be met in a limited space.

MBBR is a compact solution for achieving complete nutrient removal. It has been used for underground installations, situations where poor ground conditions demanding pyling, and fully covered plants allowing the best control of odor and noise.

Biofilm-based technologies do not rely on SRT to assure performance. As such, an MBBR plant consumes less oxygen and produces  sludge with a higher energy content than an activated sludge solution like CAS, MBR or AGS for the same performance.

MBBR or HYBAS technologies offer an Energy neutral or energy positive solution.
