  • Top 5 Advantages of Advanced Electrocoagulation Water Treatment

    Coagulation is a common practice in water and wastewater treatment processes, often used prior to filtration or sedimentation. Particles in the solution have a difficult time settling due to their common charges, which cause them to repel one another. To combat the repellant forces, the charges of the particles must be neutralized so that the colloids will cling together and precipitate, which is ...

  • Degreasing Liquid Treatment

    Degreasing is a necessary step before any other processing in mechanical industry, in the steel industry and generally speaking in the transformation of raw materials.  Degreasing is performed with aid of an aqueous solution containing detergents. The detergents emulsify oil present on the material to be treated; for this reason, oil concentration tends to increase in  ...

  • Organic Acid Fermentation Broth Clarification

    Although batch processes are currently used, a number of more advanced techniques have been investigated in order to improve the process efficiency. Promising every result must have been achieved using the tangential flow filtration in the continuous fermentation systems. One of the main advantages of tangential flow filtration is that the higher biomass concentrations are possible because cells ...

  • Four Membrane Cleaning Profiles with Micro-90® Alkaline Cleaning Solution, Micro® Green Clean Biodegradable Cleaner and Micro® A07 Citric Acid Cleaner

    SUMMARY Fouling and cleaning profiles of four types of filter membranes were obtained using MICRO-90®, MICRO® GREEN CLEAN and/or MICRO® A07. Simulated fouling processes were performed by using either a synthetic oil emulsion or a combination of the synthetic oil emulsion and a calcium acetate salt bridge mixture. Excellent recovery of permeate flux was obtained with the lowest to ...

  • RO Membrane Cleaning - explaining the science behind the art

    Introduction Reverse Osmosis membrane cleaning is essential for efficient plant operation and yet there has been very little innovation or development in over 30 years. This paper reviews best practice on reverse osmosis (RO) membrane cleaning. It challenges preconceptions and describes novel approaches for the removal of foulants and scale deposits from membrane surfaces. ...

  • Reclaiming water to Maintain future economic growth - Case study

    The Challenge How do you provide a consistent, high quality supply of water when you have a large volume ethanol distiller located in your backyard? The city of Fargo, ND came up with the perfect solution: reclaim water through the municipal wastewater treatment plant! ...

  • Save Time And Money With Preventative Maintenance

    It’s summer! It’s time to relax and enjoy the warmer weather. Kids are out of school, daylight hours are long, families flock to beaches and it seems like just about everyone takes a vacation. ...

  • Containerized MBR Plant for a motorway station in Austria - Case study

    For the Austrian motorway station at Murau, a membrane bio reactor with an AQQA®80 was installed by Wastewater Solutions Group in order to meet the stringent effluent requirements for discharge into a small river. The key factor in the choosing AQQA® for this project was the fact that the load of BOD, COD and Ammonia is high but nevertheless the membrane filter must perform without ...

  • How do I Choose the Best Detergent for My Cleaning Application?

    It’s easy to see that you have a dirty surface that needs to be cleaned. Figuring out what type of cleaner to use can be tricky! Choosing the right product from the outset will make your cleaning task easier, quicker and more efficient. So, how do you know which detergent to use? Dirt is Dirt, Right? Absolutely not! All soils are different and need to be treated properly. A detergent that ...

  • Electrodeionization is a Continuous Process

    Unlike mixed bed DI, electrodeionization (EDI) is continuous. Because electrodeionization is continuous there are no spikes in quality as when mixed beds are changed for batch regeneration. An additional benefit for EDI users is that there is no concern about the timing of changing batches, or planning for the eventual breakthrough of ions in the bed like silica, sodium, or general conductivity. ...
