Due to the continuous rise in the waste volumes worldwide it is essential constantly to seek alternatives to landfills and waste incineration: one suitable approach is bio-mechanical waste treatment. Apart from waste management, applications for air purification systems in this field range from soil remediation to sewage sludge drying in waste water treatment, as well as to the recycling of resources and their possible re-introduction.
Keeping the water in our lakes, rivers, and streams clean requires monitoring of water quality at many points as it gradually makes its way from its source to our oceans. Over the years ever increasing environmental concerns and regulations have heightened the need for increased diligence and tighter restrictions on wastewater quality. Control of water pollution was once concerned mainly with treating wastewater before it was discharged from a manufacturing facility into the nation`s waterways. Today, in many...
We can treat the air streams from waste management plants, MBT (Mechanical Biological Treatment) reception and composting areas, Waste Water Treatment Plants (WWTP), Refuse Derived Fuel (RDF) Plants, gasification of waste, syngas, torrefaction, gas engines and biogas upgrading.
In waste management plants and WWTP, we remove the odors that may be causing a nuisance to neighbors, with bioreactors using Biomass to degrade odorous components and where odors are particularly intractable or VOC emissions higher,...
MEGTEC’s experience and application know-how are at your command for tough drying and web handling applications such as slow-drying coatings and materials or thin film coating and laminating. Dryers can be equipped with a wide variety of nozzle configurations ranging from simple slot nozzles to sophisticated Coanda-style air bars and patented air foil systems. A full range of heat sources are available including steam, direct and indirect gas-fired, thermal oil, electric, hot water and IR. In addition, the air...
Evaporative gas cooling and conditioning systems help protect your downstream equipment, enhance air pollution control performance, reduce gas volumes, and increase production capacity. Central to our systems are Turbotak atomizing nozzles, which introduce a controlled amount of finely atomized water into the hot gas stream to reduce and/or maintain gas temperature. The water evaporates, while absorbing heat from the gases, for free-flowing dust, zero liquid discharge, and minimal or no wall buildup.
Context & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers high meteorological solutions. As a result of the confinement of the waste water stations, toxic components such as H2S and...
The ability to collect useful data about sediment transport and other pollutants closely coupled to SSC (such as nutrients, e-coli, phosphates and nitrates) is dependent on the timing and frequency of manual grab samples during run-off events. Most sediment and pollutant is transported during a small number of storm events which are infrequent and unpredictable. When they do occur, trained personnel or the proper equipment may not be available to collect grab samples. An automated pump sampler can eliminate the...

Accurate estimation of the spatial distribution of rainfall is critical to successfully model hydrologic processes. OneRain has worked with engineering firms and those with responsibilities in Stormwater and Wastewater Management across the U.S. to provide radar rainfall data to help characterize storm events or flow problems in collection systems and as a basis for both real-time and design-oriented modeling. OneRainware products and services offer:
*Real-time gauge-adjusted radar rainfall (GARR) data
The evaporative gas cooling and conditioning system uses a finely atomized water spray to cool EAF, BOF off-gases from over 2,400°F (1,315°C) to as low as 240°F (115°C), protecting ductwork and downstream air pollution control equipment from high temperature and sparks, while providing rapid cooling for dioxin and furan control. By optimizing humidity levels, it helps electrostatic precipitators because the water spray completely evaporates while cooling the gases. There is no free water and no...
The analysis of volatile organic compounds at low concentration levels is fundamental to pollution monitoring and control.
Hiden’s Hydramass spectrometer is a multi-stream gas analysis system for analysis of volatile organic compounds to the sub ppm level.
In sea water the analysis of volatile organic compounds is used for both pollution monitoring and ecological studies.
Hiden’s HPR 40 dissolved species analyser provides ppb sensitivity
Water pollution from airport run-off is increasingly coming under public and government scrutiny. As environmental regulations tighten, the ability to monitor for aviation fuel contamination from runway run-off has become essential.
Monitoring sites at airports can be extremely challenging often with no power or telephone lines available and with limited access for maintenance. Chelsea’s robust UviLux Hydrocarbon Sensor with its low power consumption and high accuracy is ideally suited for this application....
Environmental monitoring is becoming more important every day in local, national and international policies, showing the environmental awareness demanded by society.
This fact gives rise to an increase in the amount of legislation that obliges companies to law enforcement. Thus, the necessity of making more pollutants controls means high analysis expenses to the companies, which need to subcontract this service.
Although applications in this area advance, there is still a clear demand to get new portable and...
