  • Why choose the fiber glass filter bag with PTFE membrane treatment?

    The reasons to choose the fiber glass filter bag with PTFE membrane treatment: 1. the high tensile strength: The tensile strength of the fiber glass filter fabric is more than 4000N/50mm as usual, which is much higher than chemical fiber filter materials and the blended filter materials, that is very suitable for the long filter bags sewing. 2. Anti-corrosion Fiber glass filter bag can keep a ...

  • SALLANCHES, France: Skid–Elimination of turbidity and microbiological retention

    The Doran catchment (at an altitude of more than 1500 m) is the main resource of Sallanches. It is subject to wide variations in turbidity without a conjugate change in other parameters. Direct treatment by Ultrafiltration membrane was ...

  • MBRs and Membranes for Industrial Water Reuse in California

    ABSTRACTOver the last few years, membranes have become the preferred treatment technology in municipal water and wastewater treatment. However, industrial treatment processes have continued to rely on conventional techniques. With recent improvements in membrane technologies, and with more stringent discharge requirements for industrial systems, membranes are becoming the preferred treatment ...

  • Assessment of the value of NOM treatment processes based on a matter-element model

    Research into natural organic matter (NOM) removal in drinking water treatment processes is mostly independent, distributed, disconnected and unable to meet the needs of technology application; therefore, an assessment of the value of NOM treatment processes is necessary. In this paper, a hybrid evaluation model based on rough set theory and a matter-element model was used to evaluate the ...

  • Does the antibacterial activity of silver nanoparticles depend on the shape of the nanoparticle? A study of the gram-negative bacterium escherichia coli

    In this work we investigated the antibacterial properties of differently shaped silver nanoparticles against the gram-negative bacterium Escherichia coli, both in liquid systems and on agar plates. Energy-filtering transmission electron microscopy images revealed considerable changes in the cell membranes upon treatment, resulting in cell death. Truncated triangular silver nanoplates with a {111} ...

  • Small Community Treatment Plant Expansion While In Operation Using Advanced Technology

    The Viejas Indian Reservation in Eastern San Diego County owns and operates a gaming casino and outlet shopping mall that recently underwent a large expansion. At the same time, the Viejas Reservation Tribal Government completed the infrastructure project to provide a new water supply distribution and wastewater collection system to serve the entire reservation in addition to the casino and ...

  • Electrocoagulation: Effective Treatment of Silica Removal from Water

    What is Silica? Silica, the second most abundant element on earth after oxygen, can be found in almost every water supply across the globe. Often known for being a hard and glassy mineral substance, this element can be found in numerous forms including sand, quartz, and granite. The mineral can be found in natural groundwater supplies in the forms of colloidal silica or reactive silica. While ...

  • Wastewater treatment using bioreactor with dual functional ceramic membrane

    A novel bioreactor including a group of dual functional ceramic membranes was developed and used for wastewater treatment. The ceramic membranes could be used for both aeration and filtration alternately, so fouling to ceramic membrane would be palliated effectively as its dual functions. For 100 days operation, COD removal ratio was 88∼97% for influent COD of 154∼1389 mg/L, and NH4+-N removal ...

  • Suitability of cationic flocculants for RO membranes performance improvement

    Abstract As it has already been published and demonstrated, one of the main causes of membranes failures is related to a poor plant pre-treatment. Data from more than 600 autopsies demonstrated that both biofilm and colloidal matter are the most common components on RO (reverse osmosis) membranes fouling, therefore, main lack on membranes pre-treatment is related to disinfection and small size ...
