Sustainable operation of a biological wastewater treatment
The sustainable operation of a biological wastewater treatment plant is significantly linked to its removal efficiency, cost of sludge management, energy consumption and monitoring cost. The biological treatment offers high organic removal efficiency, it also entails significant sludge production, which contains active (live) and inactive (dead) microorganisms and must be treated prior to final disposal, in order to prevent adverse impact on public health and environment.
In this regard, the control system of biological wastewater treatment of pulp and paper production pays great attention to biomonitoring.One of the most effective methods of wastewater treatment
Development of the First Russian Anammox-Based Technology
The above-described pilot setup with a 20-m 3 bioreactor was intended for ammonium removal from the filtrate of dewatering centrifuges of digested sludge from the Lyuberetskie wastewater treatment plant (LWWP), Moscow, Russia. The reactor was inoculated by anammox sludge from the reactor, described earlier [10, 11, P. 9].During first days of reactor operation filtrate supply was 3–4 m 3 /d
The goal of biological wastewater treatment is to create a system in which the results of decomposition are easily collected for proper disposal. Biological treatment is used worldwide because it’s effective and more economical than many mechanical or chemical processes. Biological treatment usually is divided into aerobic and anaerobic processes. “Aerobic” refers to a process in which oxygen is present, while “anaerobic” describes a biological process in which oxygen is absent.
Trickling Filter for High Efficiency Treatment
The average efficiency of DAF treatment was 59.3% for BOD, 49.0% for COD and 80.0% for TP, while the average treatment efficiency of TF was 87.3%, 78.3% and 27.9% without recirculation and 95.2%
The process of biological wastewater treatment in a mixing aeration tank for the purpose of its intensification is studied. Two variants of intensification It is proposed a calculation method of partitioning of aeration volume of the mixing aeration tank, and it is shown that partitioning can increase its performance by 1.8 times and reduce power consumption of the aeration system.
Wastewater Treatment | Water | Howden
High efficiency blowers and compressors and innovative digital solutions for advanced, efficient smart aeration systems. Wastewater treatment is required to manage effluent from municipal sewage systems and from many industrial processes where liquid organic effluents are produced as a by-product.
High-rate anaerobic technology offers high COD and BOD wastewater removals in a highly loaded anaerobic system, based on a granular sludge process, with minimized footprint. Nijhuis AECOMIX TM -EGSB/UASB/IR includes a simple and efficient internal piping design and improved granular sludge retention offering a more compact, robust treatment system.
Alfa Laval - Biological wastewater treatment
Alfa Laval technologies for biological wastewater treatment are ideal for removal of nutrients, organic matter, fats, oil and grease (FOG), and other undesirable micro particles and substances. They are characterized by high efficiency, flexibility and small footprint and have all steps in the same tank.
We provide high-performance water, wastewater, and sludge treatment solutions for any size population and virtually any influent condition. We are involved in every stage of a project, from process design to equipment supply to operations training.

of metazoan microorganisms coincided with high efficiency of wastewater treatment. With their de-crease, the treatment efficiency drops as well. In order to characterize wastewater and the behavior of activated sludge, the respirometric method has recently become widespread [Cokgor et al. 2007]. Using respirograms, the consecutive

- Does anionic polyacrylamide biodegrade?
- ent only.1 BACKGROUNDAnionic polyacrylamide is the copolymer of acryl mide and acrylic acid. No studies on the environmental fate of polyac ylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biode rade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concer
