Revealing secrets about natural water purification WATER PURIFICATION: An Essential Ecosystem Service We All Need Water to Survive Water Purification is one of the many services provided by ecosystems. Pollutants such as metals, viruses, oils, excess nutrients, and sediment are processed and filtered out as water moves through wetland areas, forests, and riparian zones. This purification process provides clean drinking water and water suitable for industrial uses, recreation, and wildlife habitat.
Manual constructed wetlands treatment of municipal wastewaters. Artificial Recharge - building, sea, important, system, source, human. Water-supply development is challenging. Increasing demands for water joined with concerns for environmental protection require a variety of new water management tools. Such a tool for the conjunctive use of surface water and groundwater supplies is the artificial recharge (AR) of groundwater. Application and benefits are worldwide. Artificial recharge of groundwater is the process of adding water to an aquifer through human effort. Many different techniques and purposes exist for causing AR, but this discussion focuses on augmentation of a water supply for later use. Aquifer storage and recovery is a special type of artificial recharge of groundwater that uses dual-purpose wells for both injecting water into the aquifer and recovering (withdrawing) it later.
Artificial recharge and aquifer storage and recovery are valuable water management tools that effectively help to offset increased demands for water. Artificial Recharge Injection techniques use wells to accomplish AR. 1998_40_02_wetlands_pdf_hand.pdf (application/pdf Object) Constructed wetland. Vertical flow type of constructed wetlands A constructed wetland or wetpark is an artificial wetland created as a new or restored habitat for native and migratory wildlife, for anthropogenic discharge such as wastewater, stormwater runoff, or sewage treatment, for land reclamation after mining, refineries, or other ecological disturbances such as required mitigation for natural areas lost to a development. Biofiltration[edit] Newly planted constructed wetland Same constructed wetland, two years later Vegetation in a wetland provides a substrate (roots, stems, and leaves) upon which microorganisms can grow as they break down organic materials.
This community of microorganisms is known as the periphyton. The periphyton and natural chemical processes are responsible for approximately 90 percent of pollutant removal and waste breakdown.
