    Hazardous waste treatment solutions for metal industry

    Sludge by-products from the metalworking industry have a high potential for recycling. Prolonged grinding processes can generate large amounts of highly valuable, alloy-rich sludge; consisting of metal powder and cooling lubricants. Inside our VacuDry system, the thermal separation of the liquids (hydrocarbons, eventually water) and solids (metal powder) takes place in an oxygen free atmosphere. This absence of oxygen ultimately eliminates material degradation by oxidation, and self-ignition or explosion risks. Operation under a low vacuum ensures the possibility to recover the cooling lubricants for later reuse. After the thermal treatment, for appropriate handling in the melting process, the metal powder is pressed into briquettes. With the econ VacuDry technology, 100% recycling of all ingredients is possible.

    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.

  • Waste gas treatment for the LED industry

    Market analysts predict sustained growth in demand in the LED industry. After LED backlighting for the small LC displays of mobile phones and the LC displays of larger screens in the television market, the next potential growth market is the lighting industry: Sales of LEDs in this market in 2012 are almost USD 3.5 billion – thus nearly doubling since 2010. Analysts are expecting a growth of more than USD 7 billion in 2014 and believe that the total market for LEDs should peak at USD 17.7 billion.* A mass market of this scale for LEDs also means increasing emissions that need to be abated by specific waste gas treatment systems at the point of use. In the manufacture of products based on innovative light emitting diode (LED) technology, ammonia and hydrogen are used in large quantities as process gases. The environmental engineers at DAS have recognised this market trend and developed new solutions such as LARCH for waste gas treatment in MOCVD processes.

  • Waste gas treatment for the semiconductor industry

    In the early 1990s no appropriate and comprehensive technical solution had been available for waste gas treatment in the semiconductor industry. Back then as well as today many industrial and research production procedures use process gases and generate waste gases. These waste gases, considered greenhouse gases, are toxic and/or highly flammable and very often pose a significant risk to production facilities and the environment. The semiconductor industry, for instance, uses perfluorocarbons, whose global warming potential is extremely high and therefore requires an efficient waste gas treatment. Combining and transporting different gases into a fab’s central waste gas system might produce highly flammable and highly explosive gaseous mixtures, which in the past has occasionally caused the total loss of entire production facilities. Particles contained within gases may also cause exhaust blockages. To eliminate these risks, process waste gases need to be treated at the “Point-of-Use” (POU) where harmful exhausts are abated immediately.

  • Oxygen Generating Systems for Waste Gas Treatment in the Semiconductor, PV and LED Industries

    Waste gas treatment is an often overlooked but important function of Semiconductor, PV and LED fabrication. Several serious accidents have taken place in factories where no abatement was installed. Even today waste treatment is often seen as a cost rather than a safety issue. There are three main reasons why waste gas treatment is installed in factories: health and safety, environmental factors, and quality control.

  • Water treatment systems for chemical industry

    The effluents that accrue in the cleaning process of silo vehicles and containers for transportation of raw materials for the chemical industry, are highly complex and constantly changing in the composition of wastewater. Flocculation as the prior art of treatment for chemical waste water can not remove many of the completely dissolved invisible substances. Thus, the residual stresses are evident despite high claritv of the `Treated effluent` is often well above the levels witch are applicable for wastewater in domestic environments.

  • EPR waste minimisation monitoring for wastewater treatment industry

    The EPR regulations have replaced the IPPC regulations and are effective from May 2009 for qualifying companies within the industrial sector and October 2009 within the water sector. They will progressively require industry to minimise waste, reduce product loss and implement improved process control. The legislation will require the operator to self monitor processes and discharges, to demonstrate effective control with particular emphasis on EPR compliance and prevention. The regulating Agency will operate a point scoring system to assess operators under the OMA-3 program and this will be used to identify how well a company is managing their processes and possibly identify areas for improvement. The Environmental Permitting Regulations require industry to install instrumentation (MCERTS approved where available) to report water quality. EPR compliance monitoring may include automatic water sampling, flow measurement, pH, turbidity and TOC water analysis. Industry will need to identify point of source emissions, take steps to correct inefficient control and alarm unacceptable process deviations. Although the legislation focuses on environmental improvement, good housing keeping also makes a lot of sense. Optimisation of process control minimises waste, reduces treatment costs and ultimately saves money.

    Waste water treatment plants Personnel Safety & H2S filter management

    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.
