  • Problematic algae in the sedimentation and filtration process of water treatment plants

    Problematic algae, species that do not settle or are not easily removed by water treatment processes, are common in many water treatment plants (WTPs). We recorded algae in the water that overflowed from sedimentation basins (SBs) to filtration basins of WTPs in South Korea. Diatoms were common and other algae were not discernible in the flocs. Our field observation indicated that long and ...

  • What is a storm water filtration?

    Water is the main source of living for human beings on this earth. Water is not only essential for human life but also it is a fundamental natural resource for sustaining of wildlife and environment. It is the main substance for surviving a healthy life. There are many vital resources which contaminate the water and many death implications occur. Due to many natural calamities, the water source ...

  • Drinking Water Treatment Process

    Most drinking water comes from a surface water source, such as a lake or river, or a groundwater source, such as a well or spring. This water requires treatment before it can be safely consumed; the level to which the water is treated depends on the source of the water and also on federal regulations. In the United States, for example, the Safe Drinking Water Act was created by the Environmental ...

  • Impact of polymeric membrane filtration of oil sands process water on organic compounds quantification

    The interaction between organic fractions in oil sands process-affected water (OSPW) and three polymeric membranes with varying hydrophilicity (nylon, polyvinylidene fluoride and polytetrafluoroethylene) at different pHs was studied to evaluate the impact of filtration on the quantification of acid-extractable fraction (AEF) and naphthenic acids (NAs). Four functional groups predominated in OSPW ...

  • How to install water filtration system?

    To ensure good quality water for consumption, the clients greatly prefer the use of different water filtration systems. The water filtration systems mainly filter the water and remove the harmful chemicals or impurities present from the water. The industrial, municipal, and commercial clients greatly demand efficient water filtration system as water is one of the essential components, which ...

  • Peristaltic pumps for moving filtration water

    The Eversburg sewage treatment plant is designed to serve 250,000 population equivalents and is one of three plants operated by the city of Osnabrück in northern Germany. But in 2005, its actual load was closer to 309,000 population equivalents (COD 80 mg/l), pushing the nitrogen input level above the plant's capabilities. To deal with this situation, engineer Peter Sikora organized a team ...

  • Membrane filtration

    Membrane is a thin layer of material that is capable of separating compounds as a function of physical and chemical properties when a driving force is applied across the membrane, which has been widely used in a wide range of applications in water industry [1]. Membrane can be classified by the range of compounds separated and the driving forces employed. For example, microfiltration (MF), ...

  • Different Biological Water Filtration Systems

    Do you know what’s in your water? Most people don’t. It’s recommended that you drink at least a half-gallon of water each day. If it’s not purified or filtered, that water could be causing unseen damage to your body. Arsenic, salmonella, streptococcus, and influenza viruses could all be present in your tap water. There are many different forms of biological filtration that ...

  • Industrial membrane processes in the treatment of process waters and liquors

    A review on pulp and paper industrial membrane processes using a variety of modules and processes is presented. Membranes are mostly used today to purify process waters and to recover coating colours. Ultrafiltration using tubular membrane modules or cross-rotational (CR) filtration has been widely applied for the purification of process waters. The reuse of UF membrane permeate has decreased the ...

  • City Water International explains The Basics of Water Filtration

    The Basics of Water Filtration Most of us know that filtered water is healthier than tap water because of its purity, but how does water filtration work? The basic principle is that filtered water has passed through a filter which removes contaminants through one of several methods, depending on the type of filter. Most water purification systems work in one of three ways ­ by running water ...

  • The Filtration Spectrum

    Reverse Osmosis. Microfiltration. Distillation. Deionization. With so many types of filtration and purification systems on the market today it is difficult to determine which type of technology is best for your needs. The filtration of liquids is performed at many levels. To understand how to maximize your filtration needs, one needs to consider the size range of the particles. Once this is ...

  • Computational fluid dynamics simulations of membrane filtration process adapted for water treatment of aerated sewage lagoons

    The aim of this study is to apply the membrane bioreactor technology in an oxidation ditch in submerged conditions. This new wastewater filtration process will benefit rural areas (<5,000 population equivalent) subject to chronic water shortages by reusing this water for irrigation of green areas. For this purpose, the membranes developed without support are immersed in an aeration well ...

  • Performance of a novel recycling magnetic flocculation membrane filtration process for tetracycline-polluted surface water treatment

    A recycling magnetic flocculation membrane filtration (RMFMF) process integrating circulating coagulation, magnetic enhanced flocculation and membrane filtration was investigated for the treatment of surface water micro-polluted by tetracycline, a typical pharmaceutical and personal care product. A bench-scale experiment was conducted and several water quality parameters including turbidity, ...

  • Development of a model-based control system for membrane filtration process

    Reduction of operational cost and certification of safety for treated water are required for the membrane filtration process for drinking water. Therefore a model-based control system is developed to reduce operational cost. A process model is used for the model-based control system that calculates the transmembrane pressure (TMP) in the future. This allows the model-based control system to ...

  • Treating Your Water with a Biological Filtration System

    Poor-quality drinking water can be an enormous hazard to your health. News stories in recent years have reported experiences of unfortunate individuals who have unknowingly consumed tainted or otherwise unsafe drinking water that included high levels of lead, calcium, arsenic, and other chemicals that have serious negative health effects. Before you take another sip of your water supply, consider ...

  • Biological Filtration: Future of Drinking Water Treatment

    Water is essential for all human life on the planet, but the fresh water supply is limited and is susceptible to being contaminated by all manner of toxins like arsenic, calcium, and mercury. There are many techniques to remove contaminants, including popular methods that add chemicals to balance others out, but one that not many people understand is biological water system filtration. ...

  • Produced water filtration optimization case study

    Pentair Porous Media has worked with a major global oil & gas producer to optimize the performance of the filtration and separation at their United States mid-continent operations located in the Wind River Basin of Central Wyoming. Their operations cover more than 42,500 net acres in Wyoming. Net gas production averages greater than 100 MMSCFD from multiple formations ranging in depth from ...

  • Water filtration media: Talking about a revolution?

    Developments in any field of endeavour are nearly always evolutionary, not revolutionary. It is normal to expect advances in manufacturing equipment, process control and chemical science to facilitate product improvements. In the field of liquid filtration there is frustration at the seemingly unbreakable linkage that exists between increasing pressure drop and lower flow rates as gains are made ...

  • Sedimentation Processes

    Sedimentation is the process of allowing particles in suspension in water to settle out of the suspension under the effect of gravity. The particles that settle out from the suspension become sediment, and in water treatment is known as sludge. When a thick layer of sediment continues to settle, this is known as consolidation. When consolidation of sediment, or sludge, is assisted by mechanical ...
