    Wastewater treatment upgrades & extensions

    The time comes that a Sewage Treatment Facility Municipal or Industrial may require significant upgrading or even an extension. The upgrade usually concerns improvement process performance (removal rates) and efficiency as well as replacement of mechanical equipment. The plant expansion usually refers to an increase of the capacity or to the extension of treatment ability, ie adding Nutrient Removal.

    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.

    Towns wastewater treatment

    For this propose, AZUD has developed innovative wastewater treatment plants AZUD WW MBBR (Moving Bed Bio Reactor). This techonology is based on the growth of biomass in a plastic supports (carriers) suspended in the bioreactor mixed liquor. This carriers allow more concentreation of microorganisms per unit volume than a conventional system, reaching high quality effluent in a minimum area of implementation. In addition, our exclusive AZUD RC system allows remote management of automation and electromechanical equipment, to ensure a proper operation of all our plants at all times.

    Wastewater treatment for Medium & Large STPs

    DEVISE has developed “Smart Treatment Solutions” for larger capacities plants. Medium size STP’s up to treatment capacity of 2,300 m3/d (11,500 P.E.) are possible to implement with Packaged Systems. DEVISE is currently implementing such a STP using its revolutionary “Ultra-Clear Bio-Plant” technique which would produce an effluent quality suitable for re-use.

    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.

  • 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.

  • 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.
