Thesis Topic/Title:
Forward Osmosis Technology for Resource Recovery


Typical supernatant from anaerobic digestion of waste activated sludge and primary sludge contains 100-200 mg/L COD, 300-400 mg/L ammonia and 80-100 mg/L phosphorus. After dewatering, this supernatant is normally recycled to the head of the wastewater treatment plant which puts an additional load on the waste activated sludge process. An alternative to this is to concentrate the supernatant using forward osmosis membrane which is a natural process requiring no energy input. An increase in concentration of soluble ammonia and phosphorus by a factor of 10 will facilitate without any doubts their recovery via precipitation as struvite or apatite. Recovery of nitrogen and phosphorus as solid fertilizer is a great concern worldwide as these elements are highly valuable in agriculture
