  • 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 Pre-Filtration for RO Membrane Systems

    ABSTRACT A few years ago physical processes could only remove suspended solids from a water stream. Recent advances in technology now allow the removal of selected molecules and ions from a water stream by physical means using membranes. The membrane process has recently become very efficient and economically feasible for many industrial, commercial, municipal and even residential customers. ...

  • 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 ...

  • 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 ...

Arlat has received numerous call from sales representatives and ...

  • New Style Automatic Self-Cleaning Filters for Mill Cooling Water (Phase 1)

    ABSTRACT Replacement of hot-mill rolls is expensive and often requires production to cease during the process. Surface deterioration of rolls escalates as cooling water quality decreases. This manuscript will describe the installation and performance of a new cooling water filtration system in a northeast Ohio hot-roll mill that incorporates well proven suction scanning technology with ...

  • Smoke Factory Chooses Automatic Self Cleaning Filter for Efficient and Effective Chiller Protection

    BACKGROUND Cooling towers dissipate both ambient and process heat in most large manufacturing facilities.  These structures facilitate the transfer of unwanted energy (heat) from a transport liquid (usually water) to the atmosphere.  Problems with efficient heat transfer, equipment protection and pathological risks to employees can most often be traced back to an issue with suspended ...

  • Reduction of Solvent Use in Cleaning of Printing Screens: Cutler Brands

     The installation of new cleaning equipment at Cutler Brands printing works in Adelaide, South Australia, has resulted in a 40 percent reduction in cleaning solvent used and an annual saving of almost $165,000. Not only was the investment of $45,000 recouped in 4 months through savings and increased productivity, but exposure of employees to hazardous fumes and chemicals substantially ...


  • Effective Removal of Zebra Mussels with Amiad Screen Technology

    Introduction The zebra mussel, native to the Black and Caspian Seas, has spread in the past few decades to waterways throughout the world mostly via ballast water. Zebra mussels, when non-indigenous to the environment, pose a serious threat to intakes of facilities that rely on fresh and brackish surface water. The mussel colonies obstruct the flow of water through the pipelines eventually ...

  • How to Choose the Right Machine for Screening Silica Sand

    Quickly and accurately screening silica sand is an important priority in a number of manufacturing processes. Your choice of screening machine will have a significant impact on the quality of product you deliver and, as a result, on your bottom line and long-term financial viability. There are a number of silica sand screening ...

  • Screen Filtration Technology as Applied to Pretreatment of Reverse Osmosis and Ultra-Filtration Systems

    Summary New developments in the manufacturing technology of stainless steel weavewire screens enable mechanical style self-cleaning filters to be utilized as the primary pretreatment device for R-O and U-F systems. These systems are more cost effective and feature lower O&M requirements, than multimedia ...

  • Columbia River Gets a Vertical Fish Screen - case study

    The Columbia River is huge and runs past deserts, towns, major cities and numerous recreation areas. It is a major fishery, as well. So this screen had to protect and exclude fish, handle natural and urban debris, and operate in a constricted space.  We designed and installed large vertical fish screens with hoods. Now the irrigation canal is clean and clear of river debris. The fish are ...
