Nitrate/Nitrite Removal Applications

  • Total Reactive Nitrogen (NOy) monitoring

    NOy (total reactive nitrogen) is defined as the sum of NOX plus the compounds produced from the oxidation of NOx which include nitric acid. NOy component species include NO, NO2, NO3, HNO3, N2O5, CH3COO2NO2(PAN), and particulate nitrate.

  • Industrial water demineralisation

    Deionized water, also known as demineralised water, is water that has had its mineral ions removed, such as cations like sodium, potassium, calcium, magnesium, iron, and anions such as chloride, nitrate, sulfate, bicarbonate and even silica. Deionization is a chemical process that uses specially manufactured ion exchange resins which exchange hydrogen ion and hydroxide ion for dissolved minerals, which then recombine to form water. Because the majority of water impurities are dissolved salts, deionization produces a high purity water that is generally similar to distilled water, and this process is quick and without scale buildup.

    Industrial solutions for cooling water contamination

    Problem: Large quantities of water are used for cooling in industrial manufacturing. To prevent scaling, corrosion and biofilm in the cooling system, inhibitors and biocides are regularity dosed. Make-up water is continuously added to the system to balance the loss of water from evaporation. As water is added, the concentration of chemicals is diluted and the quality of water changes.

    Water Treatment Solutions for Nitrate Removal

    Most nitrogenous materials in natural waters tend to be converted to nitrate, so all sources of combined nitrogen, particularly organic nitrogen and ammonia, should be considered as potential nitrate sources. Primary sources of organic nitrates include human sewage and livestock manure, especially from feedlots. The primary inorganic nitrates which may contaminate drinking water are potassium nitrate and ammonium nitrate both of which are widely used as fertilizers. According to the Toxics Release Inventory, releases to water and land totaled over 112 million pounds from 1991 through 1993.

  • Water intake protection monitoring for wastewater treatment industry

    Intake protection systems have been extensively installed to protect water treatment works, from ingress of polluted water and waste-water plants from toxic chemical loads. A suitable system typically comprises a suit of instrumentation, measuring key chemical, physical and indicator parameters dependant upon the identified risks, associated with the individual site activity or discharges from neighbouring industry.

  • Industrial water Nitrate removal from drinking water

    Since nitrates are very soluble and do not bind to soils, they have a high potential to migrate to groundwater. For the short-term, excessive levels of nitrate in drinking water have caused serious illness and sometimes death. The serious illness in infants is due to the conversion of nitrate to nitrite by the body, which can interfere with the oxygen-carrying capacity of the child’s blood. This can be an acute condition in which health deteriorates rapidly over a period of days. Symptoms include shortness of breath and blueness of the skin.

  • Industrial and commercial water filtration for process water

    Filtration for Process Water is a widely used term and has a great number of uses dependent on the operation. Filtration for process water or water purification is a process where any undesirable contaminants are removed from the water to ensure it’s suitable for its intended use. The filtrat0ion of process water does not always have to be for drinking water for humans but can also refer to water purification for the use of industrial or commercial applications in a variety of industries include pharmaceutical, chemical, Paper and Textiles, Steel,  Food and Beverage, Plastics, Automotive and many more.

    Drinking water solutions for the nitrate monitoring

    Problem: Nitrate, the most stable form of nitrogen in water, is found in both ground and surface water and originates from both natural and anthropogenic sources. Due to its high solubility in water, nitrate is not filtered out from groundwater like other contaminants. Removing nitrates from source water is important as elevated levels in drinking water can cause serious health effects when ingested.

  • Continuous Monitoring of Nitrates and Other Water Quality Parameters

    Nitrate is one of the most important parameters in assessing surface and ground water quality. Nitrates are naturally present in surface and ground waters in low concentrations, but are harmful to humans and livestock and cause aquatic ecosystem degradation in high concentrations. Nitrates enter the environment as human-induced pollution from a variety of sources, but the largest source is from agricultural fertilizer runoff . Other sources include wastewater treatment discharge, septic systems, and from pet waste. Nitrate is highly soluble in water and therefore readily leaches into water sources, whereas other human associated pollutants, such as phosphates and ammonia, are not transported as easily. This ability to be quickly transported into ground and natural waters such as drinking water wells, aquifers, reservoirs, lakes, and streams, coupled with its health and environmental implications make nitrate pollution and monitoring of major concern.

    In-Situ Groundwater Remediation for the Site Remediation Industry

    In-situ groundwater remediation method is based on injection of Fe(0) nanoparticles through application wells directly into the contaminated water. nZVI injection is very fast, reaching significantly lower operating costs compared to commonly used remediation methods (expensive construction of reactive barriers, building of pump&treat stations, excavation of contaminated soil etc.). In comparison to other in-situ technologies a far lower quantities of injected chemical is needed due to high efficiency of the product and thus the time and cost of remediation is reduced.
