MIEX® Pretreatment to Micro & UltraFiltration

There are currently (in 2006) four full-scale membrane plants in operation where the MIEX® Process pre-treats water prior to the membrane process. Two plants use Microfiltration (MF) and two use Ultrafiltration (UF). This technical note highlights the benefits of MIEX® Treatment prior to MF and UF based on operating data and experience at these facilities. In particular, data is provided from the ...

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 ...

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 ...

Microfiltration and Ultrafiltration Membrane Systems: Common Problems and How to Fix Them

Microfiltration (MF) and Ultrafiltration (UF) are membrane-based filtering technologies that use thin layers of semipermeable material to separate out contaminating particles, such as organic material, bacteria, suspended solids, and other pollutants. In industries such and dairy, pharmaceutical, and chemical, the separated material may be a product they are recovering, and more facilities ...

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 ...

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 ...

Respirometric assays of two different MBR (microfiltration and ultrafiltration) to obtain kinetic and stoichiometric parameters

A comparison of two different medium scale MBRs (ultrafiltration and microfiltration) using respirometric methods has been achieved. The ultrafiltration membrane plant (0.034 µm pore size) maintained recirculation sludge flow at seven times the influent flow, and membranes were backwashed every 5 min and chemically cleaned weekly. The microfiltration membrane plant (0.4 µm pore size) maintained ...

A Practical Approach to Controlling the Fouling of Ultrafiltration Membranes: A Case Study of the Successful Development of a Commercial Soy Protein Application

Introduction Ultrafiltration (UF) membrane technology has been successfully applied to food processes for more than 20 years. Opportunities abound for new UF food applications. Some of these opportunities are described in previous literature1 and in a comprehensive report of possible UF applications in several food industries by the US Department of Energy in 1989.2 UF can save ...

The significance of interactions between organic compounds on low pressure membrane fouling

Fouling of hollow fibre microfiltration and ultrafiltration membranes by solutions of pure organic compounds and mixtures of these compounds was studied with a backwashable membrane filtration apparatus. Small molecular weight compounds resulted in little fouling, while their polymeric analogues resulted in more severe fouling. Neutrally charged dextran resulted in minor, irreversible fouling, ...

Analyzing the spatial and temporal characteristics of membrane fouling

Fouling characteristics of crossflow flat-sheet membranes for two Nanofiltration (NF), one Ultrafiltration (UF), and one Microfiltration (MF) membranes were analyzed using 12.5 parts per million (mg/L) FeCl3 solution and 350 mg/L copper nanofluid. FeCl3 solution represents dissolved contaminant whereas copper nanofluid simulates particulate contaminant. The spatial and temporal fouling ...

Validation of the Goreangab Reclamation Plant in Windhoek, Namibia against the 2008 Australian Guidelines for Water Recycling

Australia has had Guidelines in place for water recycling (for all uses other than the augmentation of drinking water supplies) since 2006. These Guidelines were extended to cover potable reuse in May 2008 and have been applied to two potable reuse projects in Australia – one a trial plant in Perth, Western Australia and the second for a large AUD$2.6 × 109 scheme in ...

Prediction of permeate flux decline in crossflow membrane filtration

Microfiltration (MF) and ultrafiltration (UF) are pressure-driven membrane processes which are widely used in order to remove colloidal particles and microorganisms in water and waste water treatment systems. The filtration performance is, however, often hampered by the buildup of retained particulate matters on the membrane surfaces, which causes the deleterious permeate flux decline. ...

Using Nanofiltration in Beverage Production

The following article is based on a paper presented in August, 1990 at the 21st Annual Meeting of the Fine Particle Society in San Diego. Soft drink manufacturers, not to mention manufacturers of other beverage products, have always had a keen interest in the water that goes into their products. After all, it is the water that typically makes up 80%-90% of the product. In the past the water has ...
