Nereda technology is the new modern standard for sustainable and cost-effective biological treatment of urban and industrial wastewater. Unique to the Nereda process is that the bacteria used to purify the wastewater
grow in fast-settlinggranules. All biological treatment processes take place simultaneously in these granules.
The Nereda technology is basedon a simple 3 step cyclic operation and takes place in one or
moreNeredareactors.Theduration and the process parametersfor thevarious stages of each cycle are automatically adjusted to guarantee optimum and efficient performance,even when the wastewater quantities, composition and temperature fluctuate.
- Infeed of the untreatedwastewater and simulta-neous decanting (displacement) of the purifiedwastewater.
- In the aeration phase, the simultaneous biological removal of organic, nitrogen and phosphorous compounds takes place.
- Fast settling phase during which the biomass isseparated from the wastewater and the Nereda plant is readyfor a newcycle.
