  • Focus on Microfiltration Part 3: Extending Service Life Using Prefiltration

    Last month we examined filter selection strategies for maximizing service life in continuous use applications.  In this 3rd installment, we will examine the use of prefilters to extend service life. Clarifying liquids with high levels of suspended solids is challenging, especially for applications requiring submicron filtration.  In these applications, filter users who experience ...

  • Basic Principles of Microfiltration

    Microfiltration can be defined as the separation of particles of one size from particles of another size in the range of approximately 0.01 µm through 20 µm. The fluid may be either a liquid or a gas. Microfiltration media are available in a wide variety of materials and methods of manufacture. They can be rated either 'absolute' or 'nominal' depending upon the percentage of capture of particles ...

  • Microfiltration Pilot System, California

    INTRODUCTION In May 2013, Pure Aqua, Inc. successfully manufactured and supplied an microfiltration pilot system to a membrane manufacturer for Title 22 certification. Title 22 is the State of California’s stringent standard for treatment/disinfection of wastewater for non-potable reuse and ...

  • Simulation of particle capture in a microfiltration membrane

    The present study takes an interest in the description of the fouling mechanisms by a numerical approach at the microscopic scale. At first, an X-ray tomography has enabled the modelling of the membrane structure for the numerical simulations. Next, for different particle size, a same volume of particles has been sent in the modelled membrane and the final permeability has been computed. Thus, ...

  • Microfiltration vs Ultrafiltration Processes: What is the Difference?

    Microfiltration (MF) and ultrafiltration (UF) are both processes by which a contaminated liquid is passed through a semipermeable membrane that removes solids too large to fit through the membrane’s pore size, yielding a purified liquid stream. To what degree the stream is purified depends on the contaminants present and the pore size of the membrane. MF and UF are generally ...

  • Reducing the effect of cyanobacteria in the microfiltration of secondary effluent

    Cyanobacterial blooms in the lagoons of sewage treatment plants can severely impact the performance of membrane plants treating the effluent. This paper investigates the impact of Microcystis aeruginosa in a secondary effluent on the microfiltration filterability and cleaning of the membrane. Alum coagulation and dissolved air flotation (DAF) were investigated to remove the algae and so enhance ...

  • What Are the Best Companies for Microfiltration and Ultrafiltration Membrane Systems?

    Whether you are looking for a microfiltration or ultrafiltration (MF/UF) membrane system that will help your facility manufacture safe food and/or beverages, boiler feed water for industrial process, or treat contaminated waste to acceptable effluent standards, it can be overwhelming to search for the MF/UF membrane system that is ideal for your specific application. MF/UF membrane systems solve ...

  • Focus On Microfiltration Part 1: Filter Longevity

    For consumers using disk, syringe, and capsule filters it is a common FAQ: How long will my filter last? Or, to put it another way: How much fluid can I expect to pass through my filter before it clogs? This seems to be a simple and reasonable question for a filter consumer: Would any of us purchase a product without an understanding ...

  • A hybrid flotation: microfiltration cell for effluent treatment

    The investigated hybrid cell combines the advantages of both flotation and membrane filtration, while overcoming their limitations and having as outcome clean water from wastewater. The specific objective of the current paper was to apply the process for the efficient separation of effluents containing toxic metals (zinc cations and chromate anions). The main examined parameters were the sorbent ...

  • Membrane foulants and fouling mechanisms in microfiltration and ultrafiltration of an activated sludge effluent

    Membrane fouling in microfiltration (MF) and ultrafiltration (UF) of an activated sludge (AS) effluent was investigated. It was found that the major membrane foulants were polysaccharides, proteins, polysaccharide-like and protein-like materials and humic substances. MF fouling by the raw effluent was governed by pore adsorption of particles smaller than the pores during the first 30 minutes of ...

  • How Much Do Microfiltration and Ultrafiltration Membrane Systems Cost?

    Microfiltration and ultrafiltration (MF/UF) membrane systems are used in a variety of processes and applications. They can help facilities treat boiler feed water, separate out contaminated waste to acceptable effluent standards, and manufacture safe food and/or beverages, to name a few. If your facility might require MF/UF membrane system technology, you are likely ...

  • Removal of DOM and THM formation potential of tropical surface water by ceramic microfiltration

    Dissolved organic matter (DOM) and trihalomethane formation potential (THMFP) removal by ceramic microfiltration (CMF) under different operating conditions was investigated and compared with the performance of a conventional water treatment plant at Bangkhen, Thailand. The tropical surface raw water for all the experiments was taken from Chaophraya River, Bangkok, Thailand. CMF studies were ...

  • Influence of buoyant media on particle layer dynamics in microfiltration membranes

    This study forms a part of the physical study of the membrane bioreactor in presence of buoyancy media. Kaolin clay suspension with buoyancy media (anthracite) was used as a suspension and the particle layer development on membrane surface with evolution of time was studied. Presence of buoyancy media reduced the pressure development by almost two folds compared to in absence of the media. The ...

  • The recovery of copper from a copper mine effluent in a hybrid flotation/microfiltration cell

    A new hybrid process for cleaning wastewater, combining flotation and membrane microfiltration, was investigated. The hybrid process combined the advantages of both flotation and membrane separation: the flotation cell removed a large proportion of suspended solid particles, while the membrane module produced clean water permeate effluent. The hybrid cell performance has been studied in depth and ...

  • Do You Need a Microfiltration or Ultrafiltration Membrane System for Your Plant?

    Determining whether or not an industrial plant needs a microfiltration (MF) and/or ultrafiltration (UF) membrane system isn’t always as straightforward as it seems. While these systems are not essential for every industrial process, when thoughtfully implemented within an intake, process, or waste stream, they can go a long way in improving a facility’s efficiency and/or cutting ...

  • Microfiltration of vinasse: sustainable strategy to improve its nutritive potential

    The purpose of this article was to evaluate and establish microfiltration (MF) operating conditions for vinasse (ethanol industries wastewater also known as stillage, slop, distillery effluent or dunder) concentration aiming to improve the use of its nutritive potential. The operating conditions influence permeate flux that has been evaluated by monitoring the flow rate profile during the ...
