Evaporative gas cooling and conditioning systems use specially engineered atomizing nozzles that introduce a controlled amount of finely atomized water into the hot gas stream to reduce and/or maintain gas temperature. The water evaporates completely while absorbing heat from the gases, which results in free-flowing dust, zero liquid discharge, and minimal or no problems with scale buildup on the walls.
Bentonite can be mixed with pesticides and fungicides as a support carrier to fix the product to the leaves. In organic farming, the action of fungi and parasites is inhibited by bentonite – a natural product – thus replacing chemical products. In particular, this process is employed in biodynamic cultivation of wine grapes, where bentonite is mixed with other elements to fight oidium. In liquid and solid fertilizers, it is used as a fixing carrier and to control the release of nitrogen, potassium,...
Food samples exhibit a challenge to analytical chemists to determine pesticide residues to meet food safety regulations in USA and EU. Therefore, more careful sample preparation is needed to successfully identify and quantify these compounds in food. Dikma offers SPE columns with different absorbent phases and QuEChERS method for sample pre-treament.
Chemical plants that produce high quantities of phenols (plastics, pesticides and pharmaceutical industries) and other aromatic organic compounds are excellent candidates for wastewater characterization via spectral analysis. Chemicals that contain conjugated double bonds absorb UV radiation remarkably well. The benefits include higher precision in process control as well as optimization of wastewater treatment.
During production of printed materials the ambient air in the working area absorbs a lot of gaseous pollutants (contaminants) that have so-called `paint smell` - solvents of various kinds (alcohols, ketones, aromatic hydrocarbons, etc.). The presence of these substances in the working area ambient air produces harmful effect at least on the personnel. In addition, solvent emission into the air is penalized in compliance with current regulation.
Pulp and paper waste streams are exceptionally well suited for spectral analysis due to the high concentration of UV/Vis light absorbing organics in their process water and waste streams. Continuous monitoring of the organic load by means of COD/BOD correlations will help ensure the treatment process is carried out in the most efficient way possible by optimizing aeration rates and nutrient dosing while also making sure that all the regulatory goals are met.

A regenerative thermal oxidizer (RTO) is a piece of industrial equipment used for the treatment of exhaust air. The system is a type of thermal oxidizer that uses a bed of ceramic material to absorb heat from the exhaust gas. It then uses this captured he
Specific industrial applications require wet end of pipe treatment for NOx or CO2. Macrotek offers absorbers utilizing various reagents for neutralization of NOx or CO2. NOx scrubbing is particularly suitable in situations where Nitric Acid can be utilized elsewhere in the plant, as it is a scrubbing product. As CO2 regulations become more stringent, methods for reducing emissions are continually being evaluated. Macrotek offers CO2 scrubbing technology which isolates CO2 in a contaminated stream to produce a...
The act of capturing and storing CO2 produced from large scale combustion plants such as power stations is becoming more and more favourable and feasible. One of the most common post-combustion CO2 capture methods is by absorption. The absorption plant can be added on to the existing combustion process, with the flue gas first passing through an absorption column where the CO2 reacts with an absorber. Amines of different types are used as the absorber. An amine CO2 capture plant can capture as much as 90% of the...
