Filamentous algae as a nutrient scrubber for agricultural drainage treatment
Filamentous algae nutrient scrubbers (FANS) have potential as a novel on-farm treatment system to remove and recover diffuse nutrients from agricultural drainage water. FANS use attached filamentous algae that grow and assimilate nutrients from the water which are removed when algal biomass is …

Conceptual design of an SOx scrubber system utilizing plant waste
… tower blowdown as possible SO<sub>x</sub> scrubber liquors has been studied. Information on analysis of ash pond water indicates that this method may be feasible. lt was found that ash from the furnace contained salts which could be used to absorb SO<sub>x</sub> in the scrubber. This would. …

Evaluation of the Performance of a Charged Droplet Scrubber (Aerosol, Collection)
The performance of a charged droplet scrubber was examined in terms of the collision efficiency and the adhesion efficiency. Two models, the fixed collector model and the accelerating collector model, were proposed to predicted the collision efficiency. The former finds its application in …

Feasibility of an integrated biogas scrubber for a swine manure digester
Laboratory experiments were conducted to study a scrubbing system for the removal of carbon dioxide (CO$\sb2$) from the biogas produced by a swine manure anaerobic digester. This innovative scrubbing system was included in the original design of an existing full-scale digester, but had never been …

Evaluation Of A Low Corrosion Method To Increase Mercury Oxidation And Scrubber Capture
… and thus, increasing the mercury capture from scrubbers.</p> <p>The proposed technology employed a low corrosion method where brominated activated carbon (ESORB-HG-11) was added to green balls to promote mercury oxidation. In Phase I, mercury oxidation potential of ESORB-HG-11 was established. …

Effect of Scrubber Sludge and Fly Ash on Soil Properties and Crop Growth
… power plants produce large quantities of scrubber sludge and fly ash that must be disposed of responsibly to avoid environmental degradation. Field and greenhouse studies were conducted to determine the effect of land application of these waste products on soil physical and chemical …

A fogging scrubber to treat diesel exhaust: field testing and a mechanistic model
… tested the efficacy of a novel, fog-based scrubber treatment for removing DPM from the air, in a laboratory setting. It was found that the fog treatment improved DPM removal by approximately 45% by number density compared to the control trial (fog off). The previous work stated thermal …

Evaluating The Effectiveness Of Proprietary Additives In Improving Capture And Sequestration Of Oxidized Mercury In Scrubber Systems
… (referred to as green balls) can be captured by scrubber waters if it is in an oxidized form. Consequently, mercury emissions from Taconite facilities can be reduced by oxidation of the mercury released from the green balls, followed by capture in their scrubbers. Moreover, sequestration of the …

Development of an Analytical Method for Distinguishing Ammonium Bicarbonate from the Products of an Aqueous Ammonia Co2 Scrubber and the Characterization of Ammonium Bicarbonate
The link between anthropogenic emissions of CO2 with increased atmospheric CO2 levels and, in turn, with increased global temperature has been well established and accepted. Using aqueous ammonia to capture CO2 and produce an inexpensive nitrogen fertilizer, ammonium bicarbonate (ABC) has been …

A comparison of antichlors used in scrubbing chlorine and chlorine dioxide from bleach plant vent gases
… Work was done on a bleach plant-packed tower scrubber system at a kraft pulp and paper mill. The pilot study was performed at pH's of 10.0 to 12.0 and therefore may have masked the scrubbing potential of two, lower pH, antichlors. Results from the full-scale trials showed that 45% Sodium …
