ABSTRACT

The nutrient recovery from wastewater is a sustainable method for wastewater management. This process accomplishes via reclaiming nutrients from the wastewater and their transformation into the valuable products for multiple applications. Several treatment processes are known for the recovery of nitrogen and phosphorus form the wastewater streams. These processes include biological treatment, chemical approaches, membrane technology, and advanced integrated systems. Membrane technology is the gold standard process in water purification as well as nutrient recovery, but conventional pressure-based membrane technologies have several limitations such as high fouling, high power consumption, and low nutrient recovery. This leads to develop the new efficient membrane-based process forward osmosis (FO), membrane distillation (MD), and electrodialysis (ED). These technologies show better performance compared to conventional pressure-based systems due to the absence of hydraulic pressure. The advantages and the limitations of existing treatment systems are discussed in this chapter and the gap areas are highlighted for the future research and developments.
