  • Explore the capabilities of nanofiltration and ultrafiltration. Filters have similar looks, different applications

    Introduction Even if you’re an expert in reverse osmosis (RO) membrane technology, you may be overlooking some applications using often neglected cousins of RO: nanofiltration (NF) and ultrafiltration (UF). Although virtually identical in looks to RO membranes, NF and UF membranes serve distinctly different separation functions. Dramatic levels of resource recovery, efficiency ...

  • Co-epuration of winery and pesticides effluents, activated sludge with tertiary nanofiltration, two new technologies for pesticides effluents treatment

    Wine-related activities produce significant volumes of wastewater characterized by high concentrations in organic matter. The term of pesticides effluents defines the water coming from the emptying and the rinsing of the equipment used to pulverize the phytosanitary products on the vines. Pesticide pollution of surface waters from vineyards applications represents a considerable hazard for the ...

  • Caustic Recovery Using Membrane Filtration

    Abstract Food and beverage processors that use dilute caustic solutions for cleaning process equipment have shown increased interest in recovering the used caustic. The primary reason is that the price of caustic has increased significantly in the past year or so. Membrane filtration technology can be used to remove suspended solids (clarify with microfiltration) and/or dissolved ...

  • Estimated costs of implementation of membrane processes for on-site greywater recycling

    Greywater reuse inside buildings is a possible way to preserve water resources and face up to water scarcity. This study is focused on a technical-economic analysis of greywater treatment by a direct nanofiltration (NF) process or by a submerged membrane bioreactor (SMBR) for on-site recycling. The aim of this paper is to analyse the cost of recycled water for two different configurations (50 and ...

  • 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. ...

  • High purify water systems for utility use

    Companies in the utility business have a need for high purity water for their operations such as in diesel generator cooling systems and in turbine generator makeup water. Often, utilities can not depend on the city water as the quality is not pure enough and purchasing local water may be expensive. To gain operational and economic advantages, water purification equipment can be added. These ...

  • Treating Industrial Water with Membrane Technology

    A variety of industries are finding that it makes sense to reevaluate the way they treat industrial process water, both to improve the quality of their products and increase the efficiency of their processes. Purification systems utilizing crossflow membrane filtration, such as reverse osmosis (RO), nanofiltration (NF) or ultrafiltration (UF) can be a good alternative to traditional filtration ...


  • Achieving Stringent Effluent Limits Takes a Lot of Energy!

    Enforcement of increasingly stringent effluent limits, and application of more sophisticated treatment processes for reduction of chemicals of potential concern, increases the energy consumed in municipal wastewater treatment processes. Energy consumption factors (ECFs) have been developed for wastewater treatment plant configurations based on the quantity of electrical energy used per cubic ...

  • Integrated approach for biofouling control

    Despite extensive research efforts, past and present strategies to control biofouling problems in spiral-wound nanofiltration and reverse osmosis membranes have not been successful under all circumstances. Gaining insight in the biofouling process is a first necessity. Based on recent insights, an overview is given of 12 potential complementary approaches to solve biofouling. Combinations of ...

  • Advanced treatment of Membrane Bioreactor (MBR) effluents for effective wastewater reclamation

    One of the two main objectives of this work is to oxidize MBR effluents with ozone/peroxide in high pH conditions in order to improve oxidation of pharmaceuticals, which could efficiently be rejected by the nanofiltration (NF) stage. The other main objective is to effectively oxidize of dissolved organic carbon (DOC) in MBR effluents in order to decrease fouling in the filtration stage. In this ...

  • Understanding Crossflow Filtration

    There's a lot of attention being given to water availability and purity, with good reason. Obtaining enough water is a struggle in some areas. In others, water is tainted with contaminants. It is therefore predictable that regulations and economics will force careful water treatment and stress water re-use. Fortunately, there are water treatment methods that can help you meet the water quality ...
