    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.

  • Biofiltration

    Biological Aerated Upflow Filtration (BAF) for high efficient Waste Water Treatment in Pulp & Paper Industry with more than 20 reference plants and more than 20 years of experience

    By AquaBiotec based in Paris, FRANCE.

  • Wastewater treatment for the paper sector

    Paper companies consume large amounts of water in the production process and hence, produce high dumped flow rates. This type of industry also tends to produce the development of filamentous bacteria. The effluent to be treated from wood industries has high loads with elevated solid matter content.

  • Biodigestor

    Bioaugmentation consists in an increase of selected bacteria that will help naturally the process of biological degradation of organic compounds. BIODIGESTOR can be applied in the biological treatment of an industrial waste-water treatment, like food industry, increasing its efficiency. BIODIGESTOR reduces COD, BOD, FOG, among others.

  • Fat, Oil and Grease treatment

    Industrial and municipal waste contaminated with fat – a frequent problem for companies maintaining wastewater network infrastructure and municipal wastewater treatment facilities. We recommend the use of GREASOLUX fat dissolvent cartridges to avoid the problems of pipeline chocking, equipment damage, offensive odors, formation of filamentous bacteria, poor wastewater treatment results, poor sedimental properties of activated sludge. GREASOLUX – is a cartridge that slowly dissolves in water, enriched with special fat dissolvent microorganisms and enzymes. GREASOLUX – is an especially efficient product for low cost solutions to problems caused by fat: only few strategically placed cartridges will remove or minimize the problems caused by fat.

  • Water treatment systems for liquid food industry

    Liquid foods such as wine, chocolate and fhiit juices cause significant peak loads in wastewater and are often not adequately treated with conventional treatment technology.

  • Residential Areas and Hostelries wastewater treatment

    Residential Areas and Hostelries wastewater, including water generated by domestic use, by shops, restaurants and laundries, must be adequately treated to meet the discharge requirements of public sewers or channel, or reuse as irrigation water mainly.

    This wastewater has the following characteristics:

    • Variations in flow depending on the time of day and season (mainly in tourist areas).
    • High suspended solids content.
    • Presence of oils, fats and detergents.
    • High concentration of easily biodegradable organic matter.
    • Adequate concentration of nutrients.

  • 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.

  • Microbial testing for biological wastewater treatment industry

    Realize a new level of process stability and efficiency! Wastewater operators have traditionally had no choice but to rely on TSS or VSS measurements to quantify biomass in their process. These measurements detect much more than just living biomass and therefore are inaccurate and unresponsive indicators of the living population.

  • Biological wastewater processes for mining

    The mining industry has the potential to use large amounts of wastewater in its operations. Often times these waste streams contain contaminants that require treatment before the water can be re-used or discharged. Biowater has successfully installed highly efficient biofilm treatment processes including our complete mix fixed film (CMFF®) system to remove BOD/COD, and nitrogen from mining waste streams. Biowater’s technologies, such as our CFIC® process, can produce effluent water quality that is acceptable for re-use, reducing the stress on ecosystems in water stressed areas.

  • Wastewater Colour Removal

    The presence of colour in water and wastewater, even a small amount, is highly visible and affects the aesthetic value. Colour is often caused by organic matter. Forms of organic content that cause colour pollution include synthetic chemical dyes, algae species and natural dissolved organics such as lignin and tannins.
