Importantly, Fe addition was found to mitigate these adverse effects when introduced by impregnation, significantly suppressing NH3 oxidation and reducing N2O formation by up to fivefold.Water vapor played a beneficial role by shifting the equilibrium of active sites from oxo to hydroxo forms, as confirmed by DFT/FPT modelling and operando IR spectroscopy. This transformation ...
Location: Germany Background: Stephan is a well known high end breeder of freshwater Angelfish, Pterophyllum scalare, in Germany with over 35 years ...
Location: Ecological-Asia, Singapore Background: Exporters and trans-shippers of ornamental fish have always faced the problem of maintaining fish health and well being as fish are shipped around the globe in plastic bags. During transport, the water in these closed containers may become oxygen-depleted asphyxiating the fish or it may accumulate excessive carbon dioxide reducing pH to toxic ...
Determination of nitrogen content Nitrate is reduced by nitrogen alloy in alkaline medium and then distilled out ammonia; or nitrate is reduced into ammonium salt in acid medium, and concentrated sulfuric acid is used to digest organic nitrogen or amido nitrogen into ammonium salt, distilling nitrogen out of alkaline solution. ...
Nitrogen is difficult to eliminate due to cyanobacteria’s ability to absorb it from the water and atmosphere and fix it into nitrites, nitrates and ammonia. To reduce those nutrients, phosphorus is targeted and removed by introducing aluminum sulfate or aluminum substitutes to the water. The use of aquatic dyes allows for wavelengths of light used during ...

Nitrate is a sneaky molecule that is difficult to remove and can migrate quickly into groundwater. This leads to concerns for elevated nutrients in waterways and can compromise drinking water. Wastewater treatment plants often don’t have strict removal requirements for nitrate, and when they do have limits, the focus is typically on total nitrogen, rather than nitrate specifically. So why ...
Continuous monitoring of nitrate enables you to keep a real-time pulse on nitrate concentrations from source water to finished water, offering many benefits: Compliance with drinking water standards for nitrate Optimized blending ratios to maximize water use Efficient nitrate treatment with ion exchange or reverse osmosis ...

Agriculture in the UK is responsible for 9% of total greenhouse gas emissions, with that number rising to 30% of worldwide total emissions.1 There are a variety of sources for such gases in agriculture, including methane production from livestock, carbon dioxide release on soil disturbance, and emissions from farm machinery.2-4The question is how to reduce such emissions. Under ...
Reducing Methane Production Finding ways to reduce methane production from cows is currently a highly active area of research. ...
Efficient use of water in commercial agriculture applications enabled by the GroGuru solution keeps fertilizer in the root zone of the crop, reducing Nitrate usage and leaching into the groundwater, and providing improved management capabilities for sustainable ...

Although the European Union’s effort to curb nitrogen pollution was put into effect 30 years ago, countries are seeking to do more to comply In 1991, the European Union (EU) initiated its Nitrates Directive (ND) to reduce nitrate water pollution from agricultural sources, which is responsible for harmful algal blooms that can decimate ...
The use of dairy wastewater (WW) for irrigation is subject to concern because of the possible nitrate contamination of domestic water supplies and health hazards from the pathogens in WW. ...
Overview Denver uses ChemScan analyzers to monitor its centrate and RAS reaeration basin (CaRRB) process, ensuring nitrate and ammonia are reduced before mainstream aeration. Challenge The Denver Metro Wastewater Reclamation District wanted near real-time nutrient analysis for a very challenging headworks wastewater aeration process. ...
In situ bioremediation was implemented to reduce the on-going cost of ground water extraction and treatment. One of the key factors in CL-Out cometabolism of perchlorate at this site was that CL-Out organisms were able to reduce sequentially the oxygen and nitrate prior to perchlorate. The initial nitrate concentrations were ...
The application of chemical fertilizers in agricultural production can increase the yield of crops, but it will cause soil compaction, the quality of agricultural products will decline, and the nitrate content in fruits and vegetables will be too high. Bio-organic fertilizers are increasingly used in agricultural production. ...
Phosphorus has been recognized as consistently reduced to the 1 mg/l limit or below, and has often been non-detectable. ...
In addition, mixed liquor is recycled from the top of the SBR tank, for removal of scum by a proprietary flow and scum control sub-system. Nitrates are recycled to the SAM tank for denitrification, with reactions said to be accelerated in the presence of unreacted carbon from the raw sewage entering that tank. Aeration and energy requirements are said to be ...
However, the plant was easy to overload, even after extensive repair work was performed on creek crossings, and after system I/I was reduced from over 1 million GPD down to 700,000 GPD. Meanwhile, during its 33-year service life, the customer base had grown from 250 residences and two small schools to 665 residences and three large schools, plus six restaurants. ...
