Wastewater treatment is the process of purifying the effluent water by removing some of its containment. This process’ purpose is to make wastewater either suitable to reuse or to discharge back to the environment. Wastewater reuse projects utilize effluent water for beneficial purposes other than the initial use.
UN Water (2015) estimates that globally, 80% of wastewater flows back into to ecosystem without being treated or reused. Wastewater reuse technologies help optimize water costs, minimize environmental impact and protect biodiversity.
Wastewater is the only water resource of which volume increases proportionally with economic development. Reuse projects offer an affordable and sustainable way of obtaining an additional source of water. Reuse systems also positively control saline ingress and recharges aquifers to sustain fresh water resources.
