Water recycling takes into account all three phases of purifying, reclaiming and reusing resources.
During purification of water, valuable resources, such as nitrogen and phosphorus, are extracted and stored. These nutrients are reclaimed as fertilizer for later use, while the purified water is also reused. Therefore, both water and nutrients are being recycled.
Purification of water using natural methods is made even more environmentally significant by the reclamation and reuse of both water and nutrients.
