nitrate water pollution Applications

  • 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.

    Pollutant Decontamination for the Wastewater Treatment Industry

    All described properties of Fe(0) nanoparticles can be even used for decomposition of pollutants contained in the waste water, mainly for treatment of industrial sewage and hutch water. The usage of nanoiron can represent a significant qualitative step in the classical technologies of water treatment including drinking water. The extremely reactive iron nanoparticles thus offer a possibility to solve long-lasting problems with a high content of uranium and arsenic in a variety of localities in the Central Europe. They can be also used for a reduction of the content of heavy metals, nitrates and phosphates in the drinking water. Just these inorganic pollutants, which are hardly or expensively removed by standard technologies, are effectively removed by Fe(0) nanoparticles.

  • Agricultural, Storm and Highway Runoff

    The ability to collect useful data about sediment transport and other pollutants closely coupled to SSC (such as nutrients, e-coli, phosphates and nitrates) is dependent on the timing and frequency of manual grab samples during run-off events. Most sediment and pollutant is transported during a small number of storm events which are infrequent and unpredictable. When they do occur, trained personnel or the proper equipment may not be available to collect grab samples. An automated pump sampler can eliminate the need to sample manually, but for the expense of a rechargeable power system, the autosampler, and possibly a datalogger and a typical turbidity probe, you’re no better off. With an automated pump sampler driven by the DTS-12 digital turbidity sensor and controlled by the Axiom H2 datalogger, you obtain a better understanding of the water’s quality, while taking a minimum number of samples, reducing site visits and saving lab analysis costs.

    Water quality monitoring for environmental industry

    Maintaining the quality of natural waters provides numerous economic benefits by preventing severe deterioration of water resources that would require expensive treatment operations to protect public health and the environment. For instance, monitoring nitrates in surface waters can possibly prevent algal blooms from happening by facilitating the necessary steps to stop pollution sources from discharging nitrogen nutrients into the water system.
