Up Flow - Anaerobic Sludge Blanket Reactor (UASB)
About Anaerobic Wastewater Treatment Anaerobic Wastewater Treatment is a wastewater treatment system using biology that without using of air or oxygen. It aimed to remove organic pollution in wastewater, slurries and sludge. Anaerobic microorganisms convert organic pollutants into a “biogas” which contains methane and carbon dioxide.1 About Up flow-Anaerobic Sludge Blanket Reactor ...

Trautwein winery - Biological sewage treatment plant for rinsing waste generated during beverage production - Case Study
The Trautwein winery, located in Lonsheim, Germany, produces a wide range of wines and juices. The production process generates rinsing water, which has to undergo treatment before it can be discharged into the sewage system. A Biomar® ASBx anaerobic wastewater treatment plant was installed for this purpose. Performance data Capacity:: 150 m³/d (max. 10 m³/h) Inflow into ...

What Is Industrial Wastewater Treatment?
Industrial progress has helped economic and social growth to a large extent, whereas, it has also created the major problem of environmental pollution at the same time as well. Industrial pollution is one of the major concerns of industries and environment protection agencies worldwide. The technical advantages have assisted the industries to reduce water pollution to a certain level. The ...

Effect of triclosan on protozoa in wastewater treating bioreactors
The effect of antimicrobial chemical, triclosan (TCS) on protozoa present in aerobic and anaerobic bioreactors for wastewater treatment is reported in this study. Bioreactor sludge ciliated protozoa such as Spirostomum, Cyclidium and Colpoda and flagellated protozoa Mastigella were exposed to TCS at 1 mg/L level in batch cultures. The response of TCS on protozoa was followed by microscopic ...

Practical BM Respirometry for biological wastewater treatment
Three different operation modes While most of the respirometers on the market offer only one operation mode, the BM respirometers have three different operation modes: OUR mode, Cyclic OUR mode, and R mode. Each mode develops different respirograms for automatic parameters including D.O., Temperature, and pH (in BM-Advance) from where specific applications can be made. In a single batch ...

New framework for standardized notation in wastewater treatment modelling
Many unit process models are available in the field of wastewater treatment. All of these models use their own notation, causing problems for documentation, implementation and connection of different models (using different sets of state variables). The main goal of this paper is to propose a new notational framework which allows unique and systematic naming of state variables and parameters of ...

Applications of two-phase anaerobic degradation in industrial wastewater treatment
Prospects for the phased anaerobic treatment of wastewater are extremely promising. With the variety of reactor designs available and the amenability of reactors to modification, existing treatment systems may be replaced or upgraded as required to achieve increased stability, higher loading capacities and greater process efficiencies than single-stage systems. In recent times, various reactor ...

Upgrading effluent quality with a plastic media based process
Wastewater treatment plant retrofits worldwide are motivated by two main developments: changes in effluent quality regulations, population growth in certain areas. In recent years, the EU (under directive EEC/271/91) and US (Section 304A of the Clean Water Act) have launched programs for nutrient removal in all existing wastewater treatment plants, originally designed for BOD and TSS ...

BM Respirometry a state of the art technology
BM respirometery is a technology where the traditional and most advanced respirometry techniques are gathered in one exclusive design developed by SURCIS Company. BM Respirometry makes use of a single reaction vessel, that in certain modes, can replicate the actions that occur at a treatment plant within the conditions set for the test. The BM-respirometers, using powerful software, provide a ...

Towards a low complexity carbon removal model for the optimal design of compact decentralised wastewater treatment systems
On-site decentralised wastewater treatment systems can provide a financially attractive alternative to a sewer connection in locations far from existing sewer networks. Operational problems and shortcomings in the design of these systems still occur frequently. The aim of this paper is to provide a low complexity (i.e. easy to calibrate) but still accurate mathematical model that can be used to ...

What is biological wastewater treatment?
Biological wastewater treatment harnesses the action of bacteria and other microorganisms to clean water Biological wastewater treatment is a process that seems simple on the surface since it uses natural processes to help with the decomposition of organic substances, but in fact, it’s a complex, not completely understood process at the intersection of biology and biochemistry. Biological ...

Cyclic activated sludge technology
Cyclic activated sludge technology was selected for the Potsdam Wastewater Treatment Plant (90,000 p.e.). The cyclic activated sludge facility comprises four modules integrated into two circular basins. Construction was commenced in February 1998 with seeding of the plant for start up taking place in October 1998. Process performance has been met since Spring 1999 at 80-90 percent of design load. ...

BM Respirometry applied to a novel control strategy of nitrification in a wastewater biological treatment
Abstract In wastewater treatment plants, the biological nitrogen removal (BNR) has acquired critical importance, which makes that in the majority of the cases the overall process control largely depends on the control of this treatment. The normal aerobic process of nitrification is performed by specific aerobic living microorganisms and a lack of information on their bioactivity may be cause of ...

Integrating anaerobic processes into wastewater treatment
Over the past decade, the concept of anaerobic processes for the treatment of low temperature domestic wastewater has been introduced. This paper uses a developed wastewater flowsheet model and experimental data from several pilot scale studies to establish the impact of integrating anaerobic process into the wastewater flowsheet. The results demonstrate that, by integrating an expanded granular ...

Hydraulic retention time influence on azo dye and sulfate removal during the sequential anaerobic–aerobic treatment of real textile wastewater
In the present study, we evaluate the behavior of real textile wastewater treatment using a system composed of two sequential pilot-scale reactors (anaerobic followed by aerobic) during 622 days. The work focused on the competition between color and sulfate removal processes, when the hydraulic retention time (HRT) was increased in the anaerobic/aerobic reactors from 16/12 hours in phase I ...

Scaling-up of a zero valent iron packed anaerobic reactor for textile dye wastewater treatment: a potential technology for on-site upgrading and rebuilding of traditional anaerobic wastewater treatment plant
Anaerobic digestion (AD) is a cost-effective technology for the treatment of textile dye wastewater with clear environmental benefits. However, the need to improve process feasibility of high treatment efficiency as well as to shorten hydraulic retention time has raised interest on several intensification techniques. Zero valent iron (ZVI) packed anaerobic digesters have the potential to ...
