    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. ...

Water filtration provides users with valuable benefits that many don’t realize yet. Here are some of the advantages of water treatment solutions like an arsenic treatment system. Improved Water Quality A good arsenic filtration system ...

  • Extensive Solutions for Removing Arsenic from Your Drinking Water

    You may not be aware that your water supply has unsafe levels of arsenic in it. If testing proves this to be the case, you must immediately find a form of arsenic water treatment to help you have access to clean drinking water again. Arsenic is a poisonous substance that has innumerable negative health effects on humans. There are several methods of performing arsenic removal from ...

  • Why evaluate hydraulic fluid compatibility?

    When introducing a new control fluid to hydraulic systems, it is important to ensure that the new liquid or mixture is of equal or superior quality to the previous fluid. If the new mixture is incompatible, precipitate may form and result in an overall inferior fluid. This can speed up clogging or damage the system. When a manufacturer of construction machinery releases a new line of bulldozers ...

  • 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), ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Whitepaper: Chemical-physical Water Treatment, Filtration and Flocculation

    Introduction In water treatment plants chemical-physical processes play an essential part in the process chain. They are successfully employed in the pre- and post-treatment of waters of different origins, as well as of other process liquids. In this regard the removal of particles by filtration is a central step. Classical filtration processes are used for particles ranging from ...

  • Bypass filtration in open circulating cooling water systems

    An open circulating cooling system is a method to remove process heat and is applied frequently for industrial purposes. In these systems heat is removed by evaporation of water to the surpassing air in the cooling tower. However there are some environmental disadvantages such as addition of chemicals to prevent the cooling water system from microbial growth and corrosion. The application of ...
