    • A particle separating apparatus for fluids containing particulate material, treatment system for treating effluent from a processing plant, and a method of separating particles from fluid. A treatment vessel has an inlet for Injecting fluid containing particulate material, and a plurality of outlets for separately discharging separated supernatant on the one hand, and separated particles on the other hand, from the fluid. An outer annular treatment region receives fluid Injected tangentially into said treatment vessel from the inlet and directs the fluid into a transverse, laminar flow within the vessel about a central axis. An Inner particle separating region communicates with the outer treatment region but Is separated therefrom by a baffle to permit Ingress of the Injected fluid gradually from the transverse flow in a radially converging manner that maintains the laminar flow for fluid. The fluid eventually reposes centrally of the treatment vessel for optimum residency in the inner particle separating region. The baffle mitigates the effects of the angular fluid motion in the outer annular treatment region on fluid within the inner separating region. A lower particle collection region communicates with both the lower portion of the outer treatment region and said inner particle separating region for receiving separated particles from the fluid having a higher specific gravity. An upper supernatant separating region communicates with the top of the inner particle separating region for egressing supernatant from the fluid for extraction. The baffle has a recess opening from the depending thereof behind the inlet and spanning a sector of approximately 90°.

    • The invention relates to a method for controlling biological waste purification plants, especially those using an activated sludge tank with a final sedimentation tank (1) attached thereto. Sludge, preferably from the overflow of the activated sludge tank (13), especially in front of the mouth of the overflow, is fed to the final sedimentation tank (14). On the basis of the supernatant collected in the sedimentation tank, measured values characterizing said supernatant are detected such as chemical concentrations (i.e. oxygen, nitrate, ammonium, phosphate), physical parameters (i.e. pH value, redox potential, color) and totalizing parameters, i.e. chemical oxygen requirement (CSB), biological oxygen requirement (BSB), total content (TOC) of organic carbon either by taking and analyzing samples or by irradiating the vessels or conducting in situ measurements. The measured values thus obtained are used for controlling sludge feeding and/or recirculating the activated sludge (from the final sedimentation tank) and/or recycling oxygen into the activated sludge tank and/or operating an effluent compensation tank and/or proportioning additives (i.e. nutrients, sedimentation additives, precipitating agents, pH regulating agents) and/or controlling denitrification and/or proportioning non-continuously emerging currents, i.e. resulting from pit evacuation or the attached industrial plants or water recycled during sludge pressing.

    • Fluorescence in situ hybridizations were used to identify and determine the abundance of nitrifying bacteria and Anammox bacteria (recycling bacteria) in freshly settled sludge of biological nutrient removal (BNR) secondary clarifiers. An uneven distribution was observed for recycling bacteria in two BNR systems. Settling patterns suggest microcolony formation processes are sensitive to the internal recycle rate, which allow for rapid recycling bacteria microcolony growth by increasing circulation of flocs through the aeration and anoxic basins. Sludge containing high levels of recycling bacteria are selectively collected and separated from the remaining sludge, uncoupling the solids retention time (SRT) of the recycling bacteria from the wasting bacteria. Elevated recycling bacteria SRTs increase concentrations of nitrifying bacteria in the aeration basin and Anammox bacteria in the anoxic basin, improving nitrification and anaerobic ammonium oxidation. Uncoupling the SRT enhances aeration and/or anoxic basin utilization and reduces the overall hydraulic residence time.
    • 荧光原位杂交用于鉴定和确定生物营养物去除(BNR)二次澄清池新鲜沉淀的污泥中硝化细菌和厌氧菌(循环细菌)的丰度。 观察到在两个BNR系统中回收细菌的不均匀分布。 沉降模式表明微生物形成过程对内部循环利用率敏感,这允许通过增加通气和缺氧盆地的絮凝物的循环来快速回收细菌微菌落生长。 选择性收集含有高水平回收细菌的污泥,并从剩余的污泥中分离出来,从循环细菌中分离回收细菌的固体滞留时间(SRT)。 升高的循环细菌SRTs增加了无氧盆地曝气池和厌氧细菌中硝化细菌的浓度,改善了硝化和厌氧氨氧化。 解耦SRT增强了曝气和/或缺氧池的利用率,并降低了整体的液压停留时间。
