Can Plants Help Outdoor Air Quality? We often hear that planting more trees is the answer to polluted cities, but is greenery really a solution, or just a comforting idea? ...
What are some of the environmental and health issues surrounding nitrate in groundwater, and options to resolve them? Nitrogen is a naturally occurring element that is essential for life on Earth. ...
With a reliable nitrate monitoring system from Real Tech and a solid management strategy, the plant is securing water quality for their community. ...
A FIRST FOR MANY Millbrook hatchery represents Octaform’s first endeavor into Aquaculture, after numerous successes in containment tanks since 1997. The aquaculture operation was the dream of Millbrook First Nation, a Mi’kmaq community that calls Nova Scotia ...
Bill Campbell and his team published a peer-reviewed journal article in Analytical Chemistry on the construction and characterization of Nitrate Reductase-Based Amperometric Electrode and Nitrate Assay of Fertilizers and Drinking Water. ...
New generation of UV Nitrate Sensors Nutrient monitoring is becoming more important as time goes on – as human activity increases the natural amount of nitrate in water, plants and organisms are more and more negatively affected. ...
Its water was not suitable for human consumption due to high levels of salts and nitrates. The Cyprus Water Development Department (WDD) awarded Fluence a Build-Own-Transfer (BOT) contract to implement a cost-effective solution to relieve the water shortage without disturbing the local population. Challenges The aquifer’s location in the middle of a neighborhood meant ...
On Herøya in Porsgrunn, Yara has an ammonia plant, three nitric acid plants and a calcium nitrate plant. Together the plants produce a wide range of fertilizers that meet the requirements for fertilization of crops under varying climatic conditions and on different soils. ...
A combined system of ion exchange (IX) and advanced biophysical treatment of a recirculating regenerant was tested for nitrate removal from groundwater with minimal brine discharge and chloride addition to the product water. Using well water containing 21.5 ± 1.4 mg NO3−-N/L, optimal IX operation was found at a service cycle of 500 bed volumes (BV). Product water nitrate concentrations (7.4 ± ...
The results showed that the most obvious consequence of ammonia addition was an overall increase in ammonia content and decrease in nitrate content in all tissues of fertilized plants. The activities of nitrate reductase and glutamine synthetase were inhibited by long‐term ammonia addition. ...
The effect of major cation activity (Ca2+, Mg2+, Na+, K+) on Ni toxicity, with dose expressed as exposure (total dissolved Ni concentration [NiTot]) or free Ni ion activity (Ni2+ in solution) or as tissue residue (Ni concentration in plant tissue), to the aquatic plant Lemna minor L. was examined. In addition, Ni accumulation kinetics was explored to provide ...
The results showed that silver content in plant tissue increased significantly with higher concentrations of AgNPs and AgNO3. Silver nanoparticles and AgNO3 significantly decreased plant biomass, caused colonies of S. polyrhiza to disintegrate, and also resulted in root abscission. Physiological analysis showed that AgNPs and AgNO3 significantly decreased ...
Chinese cabbage and Korean radish were selected as seeding plants in two sets of field irrigation experiments with various portions of the effluent. ...
A major manufacturer has developed an innovative ion exchange system for the removal of nitrate from groundwater sources. These systems have become the leading nitrate removal technology in the United Kingdom, with over 50 percent of nitrate removal plants installed in 2006-09. ...
The nitrification and denitrification process used can start with a number of nitrogen sources, but the simplified inorganic oxidation and reduction reaction sequence is commonly written as Ammonia (NH3-N)> Nitrite (NO2 -) > Nitrate (NO3 -) > Nitrogen N2 (off gas). Until now, the technologies to measure the two nitrogen species of greatest interest in such ...
In the N0 treatment, no N was applied, but in each N fertilization strategy, 180 kg N ha–1 were applied as (i) polymer-coated controlled-release urea placed 20 cm below the soil surface before planting (NLu); (ii) ammonium nitrate split-applied to the surface before planting and at V6 (early application, NEa), or (iii) ammonium ...
Helens, Ore., they produce three -urea, ammonium nitrate and ammonia. Plant drain water is discharged into the Columbia River, and although oily residues are minuscule because of a concerted program to keep oil off the floors, some is present - drippage from ammonia compressors, vehicles and machine maintenance chores. ...
Because the soils were high in nitrate-N and plant-available P, concentrations of these were high in herbage, resulting in >150 kg N ha–1 yield in seven of the entries and >20 kg P in eight entries during a high-rainfall year. ...
These technologies raise questions about plant-to-plant competition for targeted fertilizer N applications. This study evaluated the extent to which fertilizer N applied to an individual corn (Zea mays L.) plant might be intercepted by adjacent plants in the row. Depleted 15N ammonium-nitrate was injected under ...
Parameters that are essential to ensure the cleaning process on a waste water treatment plant like pH and DO Parameters that shows the efficiency of the plant like BOD and COD Parameters helping to optimise the plant like DO, ammonium, nitrate, nitrite and phosphorous Parameters that are essential to run a waste water ...
