  • Self-Cleaning Filtration for Pretreatment of Membrane, UV and Ozone Water Treatment Systems

    Recent field data has shown the effectiveness of automatic self-cleaning filters in removing suspended solids down to less than 3 microns in size without flocculents, pre-coats or granulated media. Pre-treatment of ozone systems is often needed to remove organic solids that would utilize high amounts of ozone during oxidation leaving little for complete disinfection. Selfcleaning screen filters ...

  • Removing Solids with Automatic Self-Cleaning Filters

    Introduction The “art” of filtration utilizes many methods for separating solid particles from fluids. There is often no right or wrong method. Water quality and customer requirements usually determine the “best” method for each unique situation. Ridged screens, pleated cartridges, string wound cartridges, melt blown cartridges, woven fabrics, non woven fabrics, sintered metals, granular ...

  • Self-Cleaning Filters for Pretreatment of Membrane and UV Water Treatment Systems

    The removal of suspended solids is necessary to protect membrane systems and prevent the “shadow effect” in ultraviolet (UV) treatment systems. Recent field data has shown the effectiveness of automatic self-cleaning filters in removing suspended solids down to less than 3 microns in size without flocculants, pre-coats or granulated media. Tests have demonstrated the complete removal of particles ...

  • 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 ...
