The te-cycTM process incorporates an anaerobic selector zone, which suppresses the growth of bacteria that cause sludge bulking and includes internal recycling of the biomass to the main reactor zone to create the formation of ‘macroflocs’.

The te-cycTM process, with over 500 reference plants around the world, is at the forefront of biological phosphorus removal, an enhanced biological treatment process for effective nutrient removal and sludge stabilisation.

The te-cycTM process is a cyclic activated sludge process achieving simultaneous carbonaceous, nitrification, denitrification and biological P removal. te-cycTM is an advancement on conventional wastewater treatment technologies providing efficient enhanced treatment with low energy consumption and a small overall footprint when compared to traditional activated sludge (AS) or conventional sequencing batch reactors (SBRs).

Process Description

The te-cycTM process incorporates an anaerobic selector zone, which suppresses the growth of bacteria that cause sludge bulking and includes internal recycling of the biomass to the main reactor zone to create the formation of ‘macroflocs’.  

Macrofloc cropped

In the te-cycTM configuration these larger macroflocs form an internal anoxic zone and external aerobic zone and contain polyphosphate accumulating organisms or PAO’s.  On the macrofloc surface, bacteria act to convert ammonia to nitrate whilst the PAO's take up phosphorus from the surrounding liquid. Inside the macrofloc, anaerobic bacteria convert the nitrate to nitrogen gas, which escapes harmlessly to atmosphere.

These macroflocs promote enhanced biological phosphorus removal and very low sludge volume indices and the simultaneous carbon oxidation and nitrification / denitrification in one basin enables shorter cycle times and eliminates the need for a separate denitrification treatment stage. The te-cycTM process provides enhanced phosphorus removal to achieve more stringent phosphorus effluent values without the need for an additional solids removal treatment stage.

The te-cycTM technology is a simple low operational cost solution available as a bespoke design or in a range of standard prefabricated package treatment units for effective nutrient removal, enhanced biological treatment and sludge stabilisation in multiple applications.
