  • Integrated real-time gas analysis solution for moisture in ammonia industry

    The highest purity of ammonia is a requisite chemical gas for the production of flat panel displays and for LEDs; the purity issue is one of achieving moisture levels at the ppb level, as in the case of epitaxial reactor applications. However, the problem requiring a solution derives in part from the fact that the FTIR spectra for moisture and ammonia overlap to the degree that the moisture peaks are masked by the ammonia peaks at high concentrations. As a result the moisture peaks cannot be used for quantitative...

    Determination of organic acids in beverages

    The method allows determination of organic acids, in soft drinks (juices, fizz drinks) and alcoholic drinks (wines, beer). 

    The capillary electrophoresis method for evaluation of cations concentration is based on differential migration and separation of cations in electric field due to the difference in their electrophoretic mobility. Identification and quantitative determination of the analyzed cations is performed by indirect detection measuring UV absorption at 254 nm (for “CAPEL®...

  • NH3 Monitoring in Air

    NH3 (Ammonia) is a colorless gas with a distinctive pungent smell. Ammonia monitoring is essential in coal-fired power plants, where NH3 is used to reduce NOx emissions. The ammonia consumes all of the NOx, but its high concentration that is needed for these purposes also starts reacting with other things and in the process can clog up filters and cause premature failure of expensive SCR equipment and pre-heaters. Not to mention that these high levels create an irreparable damage to the environment.

  • Odour Monitoring

    Measurement of odours from pulp & paper, feedlots and natural sources is challenging and requires careful selection of instrumentation. Ecotech offers a complete monitoring solution designed for this application. Odours are one of the most common sources of air pollution complaints and may be due to a wide variety of sources from rotting vegetation, animal feedlots, pulp and paper manufacturing, sewerage treatment facilities etc. The measurement of odours is extremely difficult due to the variety of sources...

  • Landfill Leachate Treatment

    Effluents from waste (leachate) are highly polluted and must be treated efficiently before they can be discharged into a municipal sewage plant or a local watercourse. Conventional treatment technologies do not suffice. Chemical processes are not economic due to the high pH buffer capacity of the leachate. Hardness and chlorides in the leachate are a problem for many plant components. Besides, process knowhow and operating experience are indispensable for an effective elimination of the harmful ammonia nitrogen....

  • Waste water respirometry solutions for toxicity based consents

    Water companies, water authorities or publicly-owned treatment works (POTW) need to have some knowledge of the composition of the wastes they it receive. In addition to testing for ammonia and BOD or COD levels, treatment works can license industrial discharges on the basis of concentrations of some of the known toxic compounds. However, it is recognised that very many non-regulated toxic materials still enter the treatment works and reduce the efficiency of biodegradation, and may cause toxic shock. The way is...
