sludge treatment plant Applications

  • Ozone Water Treatment for Activated Sludge Process Plants

    Ozone breaks up filaments and improves settling characteristics of the sludge... Filamentous sludge is a common problem at activated sludge plants. With ozonation of the return sludge flow it is possible to reduced the amount of filamentous bacteria in the sludge and significantly increased the settling properties of the sludge.This in turn means better performance of the activated sludge process. When a bioreactor is connected to the sludge line the removal of the damaging filamentous bacteria means higher quality sludge in the bioreactor, which leads to higher biogas production.

  • Waste water treatment / Sludge management

    PBS Velká Bíteš develops and manufactures machines for the separation of solid and suspended particles from liquids. The so-called "Decanter Centrifuges" can be used for a wide range of applications: from separation of municipal and industrial sludge in waste water treatment plants, through food and chemical industries up to agriculture. In the area of separation, we offer not only the decanter centrifuges themselves, but also the related services, including servicing of third-party equipment.

    Metal Sludge

    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. Find more information and the benefits of VacuDry® metal sludge plants on http://www.econindustries.com/applications/metal-sludge

    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.

  • Wastewater treatment solutions for controlling filamentous microorganisms

    Wastewater treatment plants can on occasion experience problems with settling of the biological sludge in the secondary clarifier. Often this problem is caused by the abundant presence of filamentous microorganisms.

    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.

  • Enhanced Biosolids and Bio Sludge Dewatering with Wilsa EWC

    IMPROVED BIOSOLIDS/ BIO SLUDGE DEWATERING WITH WILSA® CONDITIONING The WILSA ElectroWave™ effect can be used to condition polar fluids to alter their physical properties, improving several chemical and physical processes. - Reducing surface tension to improve the ability of water to repel solids - break physical / chemical emulsions - Increasing the contact angle of water - improve coalescing of solid particulate toaccelerate phase separation - Lowering the viscosity of water - reduce friction of flocculated solids dropping through less viscous water - Lower viscosity, reduced surface tension and increased contact angle of water - improve aeration of wastewater Installation of WILSA® ElectroWave Conditioner upstream of a belt press at a wastewater treatment plant resulted in polymer usage dropping by >50% while achieving much dryer solids.

  • Anaerobic Digester for Biogas Plant

    Glass fused to steel tank is made by a special process, called vitreous enamel coating ,which is an advanced technology for anti-corrosion purpose of steel plate. Tanks are coated both inside and outside with enamel .Today, glass fused to steel tank is widely used in wastewater treatment projects as aerobic and anaerobic reactors of UASB,EGSB,SBR,BAF,USR,CSTR, and equalization tank, clarifier, and sludge holding tank. It has proven its superior resistance to thermal and chemical when facing water with extremes in pH and temperature.

  • Waste water respirometry solutions for monitoring activated sludge health - sour test

    Respiration rate monitoring of Antwerp treatment works showed periods when the activated sludge was up to 40% inhibited, with resultant sludge washout episodes. Using the Health monitoring test, a pattern of ‘normal’ respiration rates for a plant can be determined. Lower respiration rates will alert the treatment works to a chronic toxicity problem, allowing corrective actions to be taken. Toxicity monitoring can now be carried out on a routine daily basis, at all treatment works receiving potentially toxic wastewaters. This is especially important if there has been a history of poor plant performance.

    Wastewater Treatment for the Bioenergy Industry

    The waste (water) streams from the production of (bio) ethanol or ethanol spirits are generally very suitable for anaerobic treatment, due to their organic compounds. 

    The effluent streams produced by the different production processes are influences by a great number of parameters such as, process design, milling process, type of raw material, etc. This requires special attention in the design of the treatment plant for this type of industry. 

    Typical streams from these industries that can be treated are, whole stillage, thin stillage, spent wash, vinasse and condensate from evaporator. The Upflow Anaerobic Sludge Blanket (UASB) process and the External Circulation Sludge Bed (ECSB) process from HydroThane are worldwide proven processes for the treatment of this type of waste water.
