    Wastewater Treatment for Municipalities

    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.

    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. In the smaller and decentralized STP’s where available investment is always lower, the on-site waste-sludge management (thickening & dewatering) maybe compromised due to the high cost of investment, largely due to the comparative high cost of facilities (building, equipment, piping, auxiliaries, etc). The DEVISE “Containerized Sludge Dewatering Plant” (CSDP) provides a first class solution for the small STP’s at a reasonable cost and most importantly it comes in a fully automated package unit that is ready to “plug & play”.

  • 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.

    Environmental dewatering solutions for municipal sewage and wastewater treatment

    TenCate Geotube technology dewaters primary, secondary and overflow sludge from the sewage treatment plants’ digesters and lagoons. This municipal dewatering solution is used in water and wastewater treatment applications including lagoons, tanks, and digester cleanouts.  The containers can provide dewatering and containment in one operation, with 85% to 90% reduction of BOD in the effluent. Most of the time, the dewatered effluent is clear and safe enough to be returned to the sewage treatment plants.

  • 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.

  • Filamentous Bulking Control with Hydrogen Peroxide

    Basis of Control with Hydrogen Peroxide Hydrogen peroxide may be used to correct a serious filamentous bulking situation or, preferably, to prevent one from occurring until adjustments can be made to remove the cause. When applied to the return activated sludge, hydrogen peroxide supplies dissolved oxygen which helps restore the microbial activity necessary for effective operation, while selectively oxidizing the filaments which retard settling. The effective dose of hydrogen peroxide is a function of time and concentration, and varies from plant to plant. To correct a serious bulking problem, immediate results may be obtained by adding 100 - 200 mg/L H2O2 to the biosolids recycle line. Once control of bulking is obtained, the dose may be reduced to 25 - 50 mg/L H2O2 to prevent re-occurrence. Practical Considerations Filamentous bulking of municipal activated sludge is not a normal occurrence, and suggests more fundamental problems may be at work (e.g., low dissolved oxygen, high sulfide input, heavy organic loading, nutrient imbalance, improper sludge age, or rapid changes in influent characteristics). Consequently, the use of chemicals such as hydrogen peroxide to control bulking should be pursued in concurrently with more fundamental corrective measures.

  • Gas infusion technology solutions for the water treatment industry

    Every municipality in the developed world has some form of water and wastewater treatment system. This varies from simple outfalls direct to the ocean to very sophisticated activated sludge plants with multiple unit processes dedicated to converting human waste, industrial effluents and storm runoff into clean water discharges and solids acceptable for some form of reuse. inVentures using its gas inFusion technology, has developed the gPRO system for the prevention and remediation of major algae blooms that negatively affect the water quality for millions of people. The company is currently working with several major water authorities on algae prevention programs by efficiently oxygenating specific regions of the water storage areas. Target Oxygenation prevents the build up of algal masses. Algal masses often require expensive treatment remedies and cause major taste and odor issues within drinking water supplies.
