With the revolutionary ByoFlex® system nitrogen is recovered from highly contaminated substrates. The ByoFlex® system is a one-of-a-kind ammonia stripping unit. Through years of experience, the (ammoniacal) nitrogen stripper has been developed for highly concentrated difficult substrates such as digestate or heavily polluted waste water. Compared to traditional ammonia strippers the system is robust and has a patented, unique design that ensures there hardly is any clogging of the internal parts. Therefore, the stripper can also treat substrates up to 15% dry matter (suspended and dissolved solids) without separation or filtration. Cleaning the ammonia stripper is easy and requires little labour and time.
