Water quality monitoring for chemical industry

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.

Chromatography systems for food industries

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.

PLAZKAT systems for treatment of printing industry emissions

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.

Water quality monitoring for pulp & paper industry

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.

Air pollution control solution for the NOx and CO2

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 pure CO2 product, making sequestration a more appealing option.

Water-blocking geotextiles

SAF is the key component for a range of geosynthetic membrane fabric technologies – which can be adapted into a wide range of formats – that are used by many industries requiring water-sealant solutions. Such fabrics are designed to act as a barrier to water and help alleviate the problems of flooding. As a fibrous super absorbent it allows for ease of handling, giving rise to exceptionally substantive and even distribution profiles within final fabric construction. As such, geosynthetic membrane fabrics incorporating this technology offer truly unparalleled levels of waterblocking performance. These fabrics have the ability to separate, filter, reinforce, protect and/or drain, and offer many advantages that are extremely important to demanding civil engineering projects. The fact that they can be supplied in rolls is also a huge benefit when being used on large-scale projects.

Measurement solution for CO2 capture by amine absorption

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 CO2 emitted from the power station and so has a real benefit for the environment. Having said this, care needs to be taken to ensure that amine emissions themselves are monitored, managed and prove no extra damage to the environment. Research is on-going to develop new amines or mixtures of amines to reduce emissions. The most common absorber in use in today’s first generation of industrial pilot plants is Monoethanolamine (MEA).
