Sludge Treatment Applications

    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.

    Metal Sludge Plants for Oil and Metal Industry

    Grinding-swarf from the metal processing industry may contain metal alloys, stainless-steel and high-alloyed steel, all of which are ideal input-materials VacuDry unit. The absence of oxygen in the VacuDry process prevents any changes in the chemical structure of the oil, emulsions or metals during the treatment. The output material can later be sold at high prices.

    Heat Transfer Equipment for Waste Water Treatment Industry

    For years we are working successfully for environmental protection. Our systems allow to conserve resources through treatment and recovery. For the treatment of wastewater, among other thin film dryers. You can concentrate pastes and sludges, thicken, dry and dehydrate. The good product turnover in the dryer can dry sludge excellent. Process water must often be treated to either be disposed of properly or again recirculate in the process circuit. These combinations of methods are often necessary. In the process of purification solution GIG Karasek thermal processes are the focus. Thin Film Dryer here are the key component.

    Municipal & industrial sludge dewatering

    The waste-sludge generated by primary and secondary (biological) treatment of municipal & industrial wastewater needs to be managed at every plant big or small. In the larger sewage treatment facilities waste sludge thickening and dewatering has always been assumed a necessity without the planners and designers thinking twice about the cost requirements.

    Real-time Control System for Wastewater Treatment Plants

    Wastewater treatment plants (WWTP) are subject to large variation in flow and load, not to speak of uncertainties on the composition of the incoming wastewater. On top of that, the activated sludge treatment process, as used by the vast majority of treatment plants, is difficult to control due to the complex behaviour of the biological process. Nevertheless WWTPs are run 24/7, with operators and management challenged to meet ever tightening environmental regulations.

    In order to meet the operational demands of modern-day plants, a new control system was developed. Proprietary control algorithms were introduced based on a large set of data from nutrient measurements in various WWTPs. The customer`s benefits are twofold: (1) achieving optimum effuent quality and, at th same time, (2) lowering energy needs and dosing of commidity chemicals.

  • Wastewater treatment for the sludge treatment

    The most used techniques to reduce sludge water content include physical-chemical processes, such as flottation or the use of mechanical systems, such as press filters.

  • 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.
