  • 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 ...

  • 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), ...

  • TEP-a major challenge for water filtration

    The latest information about the role of TEP (Transparent exoploymer particles) and their role in biofilm formation in desalination and water treatment plants. Explains why filtration or other means of lowering the levels of TEP in source water are desireable but will not be easy to ...

  • 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 ...

  • 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 ...

  • A brief history of water filtration/sedimentation

    For millennia the search for ‘pure’ water has been pursued by humans. Criteria for purity have become more complex, more rigid, and more quantitative over time; however, the principles, methods, and material for purifying water have remained remarkably similar from the earliest recorded information of 2000 BC. The scope of this paper is to present a brief history of water ...

  • 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 ...

  • 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 ...

  • Crossflow Membrane Filtration High-Purity Water Systems

    INTRODUCTION As the electronics industry continues to provide us with such products as high resolution television, notebook size portable computers and cars with automatic navigation systems, it becomes necessary to produce semiconductors with finer device geometries to allow for efficient placement of more circuits per a given area. This requires increased control of a semiconductor's material ...

  • Evaluation of electropositive filtration for recovering norovirus in water

    The virus adsorption-elution (VIRADEL) technique has been widely used in the recovery of various enteric viruses in water, and an electropositive filter such as 1 MDS has been commonly applied. However, effective methods of monitoring waterborne norovirus (NoV) have not yet been well characterized and optimized. Hence, in this study, the VIRADEL technique was evaluated and optimized for ...

  • 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. ...

  • What are the different types of water filtration systems?

    These days’ people are looking for more and more effective ways to make their lives a little healthier and hygienic than it used to be. One of the simplest and commonest means to obtain this is to research the various ways of treatment systems and to choose the best one according to your budget and lifestyle. It has become hazardously dangerous to drink tap water in the today’s ...

  • Fabrication of catalytic ceramic membranes for water filtration

    The paper describes the use of the layer-by-layer technique to coat ceramic membranes with iron and manganese oxide nanoparticles. The coatings are thin ...

  • 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 ...
