UNESCO/IHE - Photo-activated sludge process
Wastewater treatment by the Photo-activated sludge process combines the advantages of the conventional activated sludge process with those of high rate algae ponds.
In such a symbiotic ecosystem, a consortia of algae and bacteria in well-settling flocs efficiently removes and recovers nitrogen and phosphorous at much lower energy inputs and land requirements than other competing technologies.
