The ECSB HydroThane STP design offers maximum process control due to its fully controlled hydraulic mixing by external recirculation pumping. The advantage of this solution compared to some other systems that have internal circulation is its flexible management, which does not depend on “human” controlled parameters or uncertainties such as organic COD load, biogas production, wastewater composition, biodegradability and microbiological activity of available biomass.
The construction of two separators on top of each other creates maximum stability and process capacity. In the highly loaded lower part, the main degradation of organic substances and biogas production takes place, followed by a slightly loaded part where the final treatment takes place. The settling surface in the upper part of the reactor is specially designed for optimal separation of granular biomass from treated water where the best possible outflow parameters of treated water are achieved.
