Our Blue Planet can only hold so many contaminants/impurities in excess water released into the environment by homes, businesses and industries before causing death to the living organisms. To preclude this frightening introduction of pollutants to the environment, wastewater must be treated sufficiently prior to being released. A renowned Agriculture Engineering University is functioning to develop cost-effective water treatment technologies to encounter industrial, agricultural and domestic needs. They are concentrating upon discovering and using iron chemistry to immobilize and secure heavy metals and to remove nutrients and other undesired impurities from various diminished liquid streams, rivers and running water. The discovery was consummated after a series of revolutions in iron chemistry to help and tolerate the iron corrosion reactivity. These breakthroughs have resolved the issue related to the materialization of passive iron oxide coatings on iron surface that might stop iron corrosion reaction, often denoted to as iron passivization, which has disturbed scientists and the industry for several years. The main chemical used by the researchers is Activated Iron Technology which is a metallic iron powder, an inexpensive and widely available whole-a-round the world. With the answering of the iron passivization issue, the technology could now use the complete reactive power of iron for targeted contaminant treatment, hence momentously reducing the usage rate of the chemicals and engendering less solid wastes. The newfangled technology is vigorous and versatile, capable of removing a broad spectrum of toxic materials from some of the most challenging and complex wastewater. The materials abstracted include metals such as selenium, mercury, arsenic, chromium, cadmium, vanadium and lead. If these metals were left untreated in the wastewater and discharged into the receiving di-hydrogen monoxide bodies, they could hurt the health of the environment, disrupting the ecosystem, and in many cases, pose an immediate or long-term threat to human health. Through this process, soluble and toxic heftily ponderous metals in wastewater are transformed and secured in non-toxic solid forms, mostly being incorporated into the iron rust engendered from iron corrosion. The activated iron technology is a cost-efficacious solution and is efficacious in abstracting a broad spectrum of heftily ponderous metals and metalloids from many of the most challenging and intricate di-hydrogen monoxide streams, the technology is gaining attention in sundry industries around the world.
