    Wastewater Treatment

    Many industrial and pharmaceutical processes generate wastewater with volatile contaminants that increase the COD and BOD to a point where discharging to municipal wastewater is very costly or not an option. These contaminants can be removed from the water by distillation, substantially lowering the disposal cost, and, in many cases, the removed components can be further purified and reused in the process. MEGTEC offers the following solutions to remove the volatile contaminants and make wastewater suitable for discharge to most municipal wastewater treatment plants: Stripping columns using direct steam or a reboiler Distillation columns using indirect steam heat sources Our technologies have been applied to a range of processes including wastewater treatment from industries such as Pharmaceutical, Semiconductor, Chemical and Petrochemical.

    Waste to Energy

    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, thermal oxidizers to meet prescribed emission limits and odor levels. In RDF Plants, Syngas, Gasification, Gas Engine and Biogas Upgrading applications, we employ thermal oxidizers, particulate removal and DeNOX systems, for the control of VOC, NOx, CO and particulates to prescribed emission limits.

    Air dedusting for clinker cooler

    e control of clinker fines emissions after the heat exchanger, placed downstream of the clinker cooler is usually a problem for plant managers. The process is characterized by high material abrasiveness, high loads and variable flow rate in normal and maximum conditions.

    The usual dedusting arrangement is achieved through a bag house which is typically associated with high maintenance costs and downtime in production due to frequent filter element replacements.

    Continuous emissions monitoring for CO2 capture

    The process control of a CO2 capture plant needs good and reliable detection of gas phase NH3 and CO2. Measuring NH3 is a challenge due to the corrosive environment and high concentrations of NH3. Several places in the process needs to be monitored and to transport the sample is difficult. A large dynamic range is needed as the NH3 concentration can vary between 15% volume and a few mg/m3.

    Waste water treatment plants Air quality control by TRS MEDOR

    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. At the entrance of the waste water plants, where the waste water arrives, strongly smelling and polluted air is captured and neutralised by a chemical cleaning process called ‘’Stripping’’. The correct amount of chemical products needed to neutralise the polluted air has to be calculated.

    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.

  • Dust collection and odor control in waste management sites

    Th turn key plant is composed by three different wet stages. The first stage is a venturi jet scrubber to collect dust and particles, then the second and third stages are deputed to absorb bad smells, such as H2S, Ammonia and Ammines. The absorption takes place thanks to the injection of chemicals (such as Sulphuric Acid, Sodium Hypochlorite and Sodium hydroxide.

    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 Methylmercaptan increased. Safety of employees on such working sites has therefore become of major problem. To fight this hazardous pollution, air filtering systems have been installed. For the station managers, personal safety coupled with the need for constant air quality control and filter change has been a heavy task.

  • DOCUPAK LLC REDUCES COOLING TOWER CHEMICAL USAGE BY A THIRD

    Docupak LLC, a full service marketing company headquartered in Alabaster, Alabama, has reduced chemical usage by a third and removed all scale from its cooling tower at its plant after installing the patented, award-winning Scalewatcher computerized, electronic water-conditioner from Scalewatcher North America. In addition there are no longer signs of algae growth on the cooling tower louvres. Founded in 1998, Docupak, the operating name of Document and Packaging Brokers Inc., develops and distributes materials for businesses nationwide. In addition to its headquarters in Alabaster, Alabama, the company also operates a further plant in Alexandria, VA and has sales offices in Atlanta, Chicago, Cincinnati, Dallas, Los Angeles, Tampa and Washington, D.C. Aware that health agencies continually draw attention to the risks of limescale and algae in cooling towers and wanting to reduce the use of chemicals in the cooling tower, Plant Manager, Anthony Kinstley decided to install the Scalewatcher electornic water-conditioner through local dealer, Al Chatham of Water Processing and Well Supply in Harpersville, Alabama. An industrial Scalewatcher was installed on to the water-feed line to the building and then a further unit was specifically fitted on to the recirculation line of the cooling tower. “Since using the system the scaling on our cooling tower has been eliminated and we currently use only a third of the original chemicals intended for the water treatment within our system”, said Anthony Kinstley. Many air conditioning and refrigeration plant systems are water-cooled. The heat generated by cooling coils is removed by water, which is passed through a water-cooling tower. These are recirculating systems, which operate at temperatures ideal for bacterial and algae growth, and have plentiful supplies of nutrients. In cooling towers, temperature, water hardness, pH, scale and corrosion are all factors, which increase the chance of biofilms, algae and Legionella colonization. The environmentally friendly Scalewatcher provides a permanent solution to hard water problems without the need of chemicals, salt or maintenance. It works by producing a varying electronically applied force field, induced by a coil wrapped around the outside of the pipework, which keeps the minerals in suspension and thus prevents limescale forming. The water’s increased solubility enables it to dissolve existing scale, which is gradually washed away. “Scalewatcher has proven itself to be highly effective. I would highly recommend this product and service without limitation,” concluded Antony Kinstley. Scalewatcher models are based on continuous research and over 25 years experience and expertise as market leaders in electronic scale control with countless units sold worldwide. The patented Scalewatcher systems are capable of treating pipe sizes from one to 120 inches. All Scalewatcher systems come with a full performance guarantee and are shipped throughout North America.
