چکیده

residues is applied to the land, it undergoes numerous chemical, physical and biological reactions. In its nitrate form (NO3), it can move down through soil into groundwater. Nitrate can also be a factor in surface water quality problems. In sufficient concentrations, nitrate in drinking water can be toxic to infants. Scientists are also investigating possible links between nitrate and other long-term health effects, though none have yet been demonstrated.

مطالعه حذف نیترات از منابع آبی با استفاده از پودر منیزیم

Background and Objectives: Nowadays nitrate concentrations in surface water and especially in groundwater have increased in many locations in the world. Since nitrates cause many health and environmental concerns, increased nitrate concentrations in groundwater have led to rendered aquifers unusable as water sources. So, as the water demand is still increasing the throughout the world, decreasi...

Nitrate Removal for On-Lot Sewage Treatment Systems: The POINT System

Nitrate-nitrogen (NO3-N) in groundwater is becoming a ubiquitous problem, particularly in rural and suburban areas where domestic water supplies are obtained from individual on-lot water supply wells. Nitrate in groundwater can come from natural sources such as soil, bedrock and organic material; however, the overwhelming loading of nitrate originates from anthropogenic sources, particularly ag...

Sources of Chemical Contaminations and Classification with Emphasis on Drinking Water

Groundwater contamination is a serious problem facing the countries. Because groundwater is vulnerable to contamination from a variety of sources, and, once contaminated, it is very difficult to restore to its original quality. The main objective of this study was evaluation of groundwater quality in Shahrekord aquifer and finding the source of the groundwater contamination. Some of the chemica...
