  • Understanding Carbon Mesh Size: Smaller granules equal bigger performance

    Full Abstract: Carbon filters for domestic water treatment are increasingly popular, but many water treatment professionals may not realize the impact carbon's 'mesh size' can have on a filter's performance. Mesh size, which indicates the range of particles sizes in a particular carbon product, is an important physical consideration. Other ...

  • Application of chlorine resistant polyamide RO membrane for household water filtration device

    Chlorine attacks the polyamide RO membrane to cause membrane failure as measured by enhanced passage of both salt and water. For this reason, activated carbon pre-filters that remove chlorine are typically placed ahead of RO membranes in home drinking water treatment RO system. A general home drinking water treatment system employing RO is composed of preliminary sediment filter, activated carbon ...

  • Basics of Drinking Water Filtration: How Do Carbon Filters Work?

    How do carbon filters work to remove toxic chemicals in a drinking water supply?Whether you buy a bottle of water or turn on the faucet at home for a drink, the last thing you want to worry about is that it might be contaminated with bacteria or toxic chemicals. In developed countries and cities that have advanced drinking water treatment facilities set up, they have methods for dealing ...

  • Treatment on low carbon-to-nitrogen micro-polluted water by layered biological aerated filter with floating and sunken media

    In order to improve the TN removal efficiency on low carbon-to-nitrogen micro-polluted water, in this study, a layered biological aerated filter (L-BAF) was built. The results showed that the removal efficiency for CODMn, NH3-N, and TN was 71.6–90.3%, 99.8–99.9%, and 57.8–65.7%, respectively, when the C/N ratio was kept at 3 and the volumetric ...

  • What is Activated Carbon?

    Adsorption with activated carbon can apply. The more awareness people have of the Earth, the more applications activated carbons will have. is thus a commonly seen process in applications such as gas masks, space capsules, nuclear plants and so forth, in which the removal of gases is highly needed. ...

  • Advances in String-Wound Sediment Filter Cartridges

    In the mid-1930s, the first string-wound depth filter cartridge entered the U.S. market. It was made from a woven wire mesh core surrounded by a cotton yarn, which was wound to form the depth filtration medium. The yarn itself was a tightly twisted medium and the major filtration essentially took place at the points of crossings of the yarns- which formed a diamond-shaped pat-tern-rather than ...

  • Pharmaceutical / Personal care product manufacturer promotes quality standards

    Challenge Pharmaceuticol manufacturers demand high qualify water with the fewest dissolved solids possible, to promote product consistency. A Canadian manufacturer of pharmaceutical/personal core products was looking to maintain water quality specifications to promote product consistency and improve product shelf life. First the source water for the manufacturing plont comes from ...

  • Getting the lead out — at the faucet

    You might be surprised at where you’ll find a customer’s lead. Lead is making headlines. First, we should note that the current attention is not due to water, air or soil contamination, but from lead contamination recently found in toys and children’s jewelry made in China. This is very frightening for any parent because of the harm lead can to cause in children. How could this happen? How ...

  • CSPC chooses UF/DEMIN/PCC/NCC

    The Facility CNOOC and Shell Petrochemicals Company Limited (CSPC) made petrochemicals history in China by building and operating a USD 4.3 billion petrochemicals complex in Daya Bay, Huizhou Municipality, Guangdong Province. It is the largest capital investment for a Sino-foreign joint venture project to date in the People’s Republic of China. The joint venture partners are ...

  • The Best Ground Water Treatment Methods

    Many homes and businesses depend on ground water or surface water as a vital water source. Unfortunately, much of this water has not been filtered through municipal water treatment and distribution technology. This means that the water many people consume, cook with, and use for basic hygiene can contain potentially harmful particles, including pathogens, tiny organic matter, sediment, ...

  • The impact of organic carbon on the performance of a high rate nitrifying trickling filter designed to pre-treat potable water

    The application of nitrifying trickling filters (NTFs) to potable water treatment is less well understood than their application to wastewater treatment, particularly regarding the effect of low ammonia substrate concentrations and organic carbon loading on filter performance. A large pilot-scale NTF was operated under conditions that simulated the raw water quality of poorly protected catchments ...

  • Identification of bacteria assimilating formaldehyde in a biological activated carbon filter by means of DNA stable isotope probing and next-generation sequencing

    Ozonation followed by a biological activated carbon (BAC) filter is a common process of advanced water purification. Ozone can generate formaldehyde (FA) as a harmful by-product, while the subsequent BAC filter is efficient at removing FA. FA adsorption is limited on activated carbon because of its hydrophilic property and low molecular weight. Thus, biological degradation by biofilms ...

  • Nitrate removal using different carbon substrates in a laboratory model

    Agricultural fields have been frequently identified as major contributors of nitrate leaching into surface and ground waters. Tile drains can act as direct pathways, transferring leached nitrate to surface water. Bioreactor filters are useful for the removal of nitrate from drainage waters; however, these filters require an external carbon supply to sustain denitrification. In this study, four ...
