  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Coal cinder filtration as pretreatment with biological processes to treat pharmaceutical wastewater

    This study aims at coupling coal cinder filter with biological process to improve pharmaceutical wastewater quality and reduce the disposal cost. In the coal cinder filter, the removal efficiencies of COD, BOD5, SS and color were 90±2%, 72±2%, 95±2% and 80±2%, respectively. The results attribute to the big specific surface area and strong adsorption ability. Coal cinder filter removes a large ...

  • What water filtration system do I need?

    Water is abundantly available on the surface of the Earth. But do you know only 10% of the water is consumable, and the rest of the water is not usable? As the population is rapidly growing, the need for the consumable water is also growing. This increasing need for water has resulted in a scarcity of water in different regions. In such cases, the only solution is to reuse the ...

  • 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, ...

  • 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 ...
