    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.

    Hazardous waste treatment solutions for oil and gas industry

    There are a wide amount of applications for our VacuDry® process within the oil and gas industry. A large variety of wastes and by-products that are generated in the oil & gas production chain can be treated effectively and sustainably. In past decades, numerous thermal desorption processes have been implemented worldwide, using a variety of heating chamber designs to separate hydrocarbons from the mineral solids. Such standard TDUs work under atmospheric pressure which can lead to safety risks, high energy consumption, larger emissions and limited flexibility regarding altering feed materials. Due to its unique design, the complications outlined above are avoided throughout the VacuDry® process. When it comes to treating standard oily wastes, mercury-containing waste streams, NORM, and especially for the recovery of highly valuable drilling fluids from drill cuttings; our vacuum thermal desorption process (i.e. vacuum distillation) is economically unbeatable.

  • Filtration in waste water treatments. disinfection

    The cost and efficiency of the waste water treatment is directly linked to the amount of suspended solids in the water.
    The addition of an AZUD System allows:

    • Increased efficiency of the treatment equipment.
    • Decreases the quantity of chemicals used.
    • Avoids the “shadowing effect” created by larger particles in UV disinfection systems.

    Reliable Shredding Technology for Hospital Waste

    Our shredding machines are perfectly suited for the chemically aggressive material in your hospital waste. After the shredding process, the material can be optimally utilised thermally or disposed of together with municipal solid waste once it has been sterilised. The shredding is so effective that the granulate does not give any indications of the source material. Hospital waste consists of very different types of waste and requires special treatment during disposal due to the presence of infectious and highly contaminated materials. Depending on the waste type or classification, the hospital itself might need to specially treat the waste or store it in dedicated plastic containers or drums on-site.

  • Using evaporation to dewater Reverse Osmosis reject waste streams

    Reverse Osmosis (RO) technology has been used for years in various industries to separate dissolved solids from water by forcing the water through a semi-permeable membrane. RO is also commonly used to purify drinking water and desalinate seawater to yield potable water. The water and other molecules with lower molecular weight (specific weight of molecules allowed to pass through is dependent on the selected membrane) pass through the micropores in the membrane, yielding a purified water stream called the permeate. Larger molecules are retained by the membrane as well as a portion of the water that does not pass through the membrane. This concentrated stream is called the concentrate or RO reject.

  • Odour and corrosion treatment solutions for wastewater treatment industry

    Odour emissions form a serious problem for many people that live near or work in places which produce odours. These places can be factories, wastewater treatment plants, farms like pig and poultry breeders, solid waste disposal facilities and landfills. As some odourous compounds can be harmful for the health of humans other are simply unpleasant and can cause health problems when exposed to on a continuous basis. In either case something needs to be done about it.

  • Waste management for hotels and resorts

    Yet, while the people living in today’s wealthy societies can easily escape their every day life and enter the pristine world of unspoiled nature, they cannot escape their propensity for generating garbage. On average, a person generates about half a kilogram of solid waste plus approximately 300 liters of wastewater per day. Tourists frequently generate more waste than the average. Thus, a resort that hosts about 300 guests and staff will generate over 50 tonnes of solid waste and 30,000 tonnes of wastewater per year. Where does a resort located far away from any conventional waste treatment facility dispose of all this waste?

    Industrial Solution for incineration & thermal treatment

    Waste incineration, including solid municipal and hazardous waste, biomedical waste and hazardous liquid are all continually under more stringent scrutiny by regulators. Macrotek has designed and supplied many integrated systems to meet most guidelines. In several installations, hazardous waste has been combined with radioactive waste, requiring nearly non-detectable emission levels for many of the contaminants. Macrotek has installed and tested systems for these processes with the results significantly better than required standards.

  • Headworks Odor and Corrosion Control Using Hydrogen Peroxide

    Hydrogen Peroxide typically controls odors and corrosion at treatment plant headworks by direct oxidation of hydrogen sulfide (H2S) within the wastewater. In the direct oxidation mode, H2O2 is applied to the wastewater 5-30 minutes prior to the point where the odors are being released, generally as the wastewater line enters the plant boundary. The efficiency of hydrogen peroxide treatment depends upon the available reaction time, the level of iron in the wastewater (reaction catalyst), wastewater pH and temperature, and the initial and target levels of H2S odor. Under optimal conditions, effective dose ratios are 1.2 - 1.5 parts H2O2 per part dissolved sulfide, and can be reliably estimated through beaker tests. H2O2 + H2S → S0 + 2H2O Frequently, control of odors through the primary clarifiers is wanted. In such case, the mechanism of control is both direct oxidation of H2S (as it rises from the solids blanket), and prevention of odor generation (by supplying dissolved oxygen). Control is typically achieved with a booster dose of 1-2 mg/L H2O2 added to the clarifier influent. Higher doses or alternate modes of addition may be required in cases where: 1) hydraulic retention times are > 2-3 hours; 2) solids blanket depths are > 1-2 feet; 3) soluble BOD levels are > 200-300 mg/L; or 4) waste activated sludge is co-settled with the primary solids. 2H2O2 → O2 + 2H2O
