  • 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 ...

  • Assessment of an ultrafiltration pre-treatment system for a seawater reverse osmosis plant

    The seawater reverse osmosis system requires extensive pre-treatment in order to ensure reliable performance. The conventional pre-treatment system involves dosing of chemicals, which requires frequent monitoring of raw water quality, and also involves adjusting the dosage. Besides being cumbersome, there is a lot of time lag involved in carrying out these measures. This calls for pre-treatment ...

  • Ultrafiltration and Reverse Osmosis for Landfill Leachate Treatment

    Lanchester Landfill serves Eastern Lancaster County and Western Chester County in PA for disposal of household and construction waste. The facility produces around 10,000 gals per day of leachate. The Problem The facility ran a single basin sequential batch reactor (SBR) and a filter press to dewater the solids for many years, but found that they first, could not sustain a ...

  • Effect of enhanced coagulation by KMnO4 on the fouling of ultrafiltration membranes

    Pre-coagulation enhanced by KMnO4 before ultrafiltration (KCUF) was compared with normal pre-coagulation by alum (CUF) in the ultrafiltration of water from the Songhua River, China. The trans-membrane pressure (TMP) with KCUF was much lower than that when alum alone was used. With KCUF a slower increment of TMP occurred, even under conditions of high river water turbidity. The results also showed ...

  • Ideal treatment of laundry wastewater with ultrafiltration installations

    Treatment of very dirty work clothing also produces heavily polluted, oily/greasy wastewater. It is the aim of laundry wastewater treatment to reduce fresh water consumption and to minimise the volume of residuals. At the same time, adherence to the limit values according to appendix 55 of the General provisions on hydrocarbon, heavy metal and AOX contamination in wastewater must be guaranteed. ...

  • 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 ...

  • Predictability of fouling-potential of raw water for ultrafiltration membranes

    The public drinking water supply of southern Germany is characterized by a rather decentralized network. Due to the hydrogeological setting in these parts of Germany many of the small water works with an average capacity of 50 m3/h have to treat raw water extracted from karstic or cliffy aquifers. These raw waters tend to be contaminated with particles and pathogens acquired during snowmelt or ...
