    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.

    Water Testing for Environmental Applications

    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 cases, there are restrictions on wastewater that is discharged to city sewer systems or to other publicly owned treatment facilities. Many jurisdictions even restrict or regulate the runoff of stormwater — affecting not only industrial and commercial land, but also residential properties as well.

    Compressed air, gas and vacuum solutions for water and waste water treatment

    There are many options to apply methods to avoid damaging the environment. In the case of wastewater e.g. the ventilation of the sediment tank or the pressure ventilation of biological wastewater treatment systems. The oxygen introduction is important, for deep wastewater tanks, wastewater treatment systems with standard aeration tanks or natural clarification ponds alike. If the wastewater has already entered the natural cycle, ventilating lakes and rivers prevents additional contamination. When treating drinking water, rinsing the filters with compressed air ensures that perfect water is provided and natural water reserves are not used excessively.

    Advanced water treatment equipments for deionization

    Deionized water, also known as demineralized water (DI water or de-ionized water; can also be spelled deionised water), is water that has had its mineral ions removed, such as cations from sodium, calcium, iron, copper and anions such as chloride and bromide. Deionization is a physical process which uses specially-manufactured ion exchange resins which bind to and filter out the mineral salts from water. Because the majority of water impurities are dissolved salts, deionization produces a high purity water that is generally similar to distilled water, and this process is quick and without scale buildup. However, deionization does not significantly remove uncharged organic molecules, viruses or bacteria, except by incidental trapping in the resin. Specially made strong base anion resins can remove Gram-negative bacteria. Deionization can be done continuously and inexpensively using electrodeionization.

    Argos Sequencing Batch Reactor (SBR)

    The Argos® Sequencing Batch Reactor (SBR) is a True Batch SBR system that combines capabilities of anaerobic, anoxic, aerobic, and secondary clarification into one basin. A True Batch SBR, unlike a Continuous Flow SBR, provides a consistent cycle structure within a circular, rectangular, or square basin. A Continuous Flow SBR requires a long rectangular basin to avoid pollutant “short circuiting” and has unpredictable cycle times since it is dependent on the flow. All components provided with the Argos® SBR are accessible from the surface. View our website for details: https://www.aireo2.com/products/argos-sequencing-batch-reactor/

    Ultraviolet disinfection systems for the total organic carbon (TOC) reduction sector

    Total Organic Carbon (TOC) is found in all water supplies as naturally occurring organic matter. Over many years of experience, medium or low pressure UV treatment has become recognised as an effective process step in the breakdown and reduction of TOC in water intended for use in pharmaceutical, health care, power generation and micro-electronics applications. In the latter case, ultra-pure water is used to wash silicon wafers on which even small deposits of carbon compounds on the wafers can severely affect their performance.

    Solutions for the wastewater sector

    Conventional wastewater treatment systems are focused on efficient removal of polluting components. This is commonly done through aeration and separation of formed biomass from the cleaned water. After treatment the water would be discharged onto surface waters or subsoil irrigation. Introduction of polishing steps after these treatment systems opened up the possibilities to reuse water for either irrigation or even potable water. DMT Environmental Technology also implements these solutions with its MemBioRex membrane bioreactor. Nowadays novel technologies enable reuse of saline water within industries such as unconventional oil and gas, industry, agriculture, and mining. DMT Water Technology develops and realises innovative products to enable our customers to meet these challenges.

  • Sulfide Oxidation with Hydrogen Peroxide (H2O2)

    Sulfide Odor Control Sulfide is found throughout the environment as a result of both natural and industrial processes. Most sulfide found in nature was produced biologically (under anaerobic conditions) and occurs as free hydrogen sulfide (H2S) - characterized by its rotten egg odor. We are most likely to encounter biogenic H2S in sour groundwaters, swamps and marshes, natural gas deposits, and sewage collection/treatment systems. Manmade sources of H2S typically occur as a result of natural materials containing sulfur (e.g., coal, gas and oil) being refined into industrial products. For a variety of reasons - aesthetics (odor control), health (toxicity), ecological (oxygen depletion in receiving waters), and economic (corrosion of equipment and infrastructure) - sulfide laden wastewaters must be handled carefully and remediated before they can be released to the environment. Typical discharge limits for sulfide are < 1 mg/L. Sulfide Treatment Alternatives There are dozens of alternatives for treating sulfide laden waters, ranging from simple air stripping (for the low levels present in groundwaters) to elaborate sulfur recovery plants (used to treat several tons per day at refineries and coal burning power plants). There are processes based on biology (using compost filters, scrubbing media, or inhibition/disinfection), chemistry (oxidation, precipitation, absorption, and combination), and physics (adsorption, volatilization, and incineration). Each process occupies a niche which is often defined by the scale and continuity of treatment, whether the sulfide is in solution or is a gas, the concentration of sulfide involved, and the disposition of the sulfide containing medium. However, for reasons relating to convenience and flexibility, chemical oxidation (using hydrogen peroxide) continues to grow in its scope of application. Treatment with Hydrogen Peroxide While other peroxygens such as permonosulfuric (Caro’s) acid, peracetic acid, and persulfates will oxidize sulfide, their use for this application is overkill. Hydrogen peroxide (H2O2) is considerably simpler and more cost-effective. H2O2 may control sulfides in two ways, depending on the application: Prevention - by providing dissolved oxygen which inhibits the septic conditions which lead to biological sulfide formation; and Destruction - by oxidizing sulfide to elemental sulfur or sulfate ion.
