Water reclamation & phyto -technologies

Abstract

In this paper conventional and innovative phyto-technologies, applied on different kinds ofpolluted waters to obtain their safe reuse, are showed. Today, the last frontier ofenvironmental recovery in the world is: Water Reclamation. Most important targets of waterreclamation are: recover and reuse wastewaters in safety, freshwater aquifer recharge, publichealth protection, and new economic viable source. There are a lot of technologies to treatdifferent kinds of wastewaters (urban, industrial, zootechnical, etc), but conventionaltechnologies able to treat, recover and reuse wastewaters in the same time, are very few and soexpensive that the cost of recovered water is no sustainable by public administrations; overallin the developing countries in Africa, Asia, South and Centre America (F AO-WHO).In the latest years, phyto-technologies proved their efficiency in the wastewater reclamationand their cheap and easy way to be built and maintained. The phyto-technologies experiencesshown in this paper are applied on polluted waters from industries and agroindustries, pigfeedlot, towns, and polluted water of rivers and/or lakes. The paper is completed withanalytical data and results; compared with national and/or international (F AO-WHO) lawlimits for reclaimed waters; and building and maintenance costs, compared with conventionalactivated sludge systems.We speak about projects financed by public administrations or international organizations(F AO-European Union) and realized to reclaim and reuse treated wastewaters usingconventional and/or advanced phytoremediation technologies. All this has opened a newcheap and easy way, to reuse in safety treated waters, to protect environment, and to controlfresh water pollution.
