  • Seawater Reverse Osmosis (SWRO)

    Seawater Reverse Osmosis (SWRO)

    Sea Water Reverse Osmosis (SWRO) is a reverse osmosis desalination membrane process that has been commercially used since the early 1970s. The typical single-pass SWRO system consists of the following components: Intake, Pretreatment, High pressure pump, Membrane assembly, Remineralisation and pH adjustment, Disinfection, Alarm/control panel. Pretreatment is important when working with RO and nanofiltration (NF) membranes due to the nature of their...

  • Brackish Water Reverse Osmosis

    Brackish Water Reverse Osmosis

    Reverse osmosis (RO) is a filtration method that removes many types of large molecules and ions from solutions by applying pressure to the solution when it is on one side of a selective membrane. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side. To be 'selective,' this membrane should not allow large molecules or ions through the pores (holes), but should allow...

  • Ion Exchange

    Ion Exchange

    Ion exchange is an exchange of ions between two electrolytes or between an electrolyte solution and a complex. In most cases the term is used to denote the processes of purification, separation, and decontamination of aqueous and other ion-containing solutions with solid polymeric or mineralic 'ion exchangers'. Ion exchange resin beads. Typical ion exchangers are ion exchange resins (functionalized porous or gel polymer), zeolites, montmorillonite, clay,...

  • Glass Lined Tanks

    Glass Lined Tanks

    Glass-fused-to-steel is the premium technology in the tank market. Glass coating's physical properties are specially suited to municipal and industrial storage applications. The factory-applied silica glass coating on tanks forms a hard, inert barrier for both the interior and exterior tank surfaces to guard against weather and corrosion. Glass-fused-to-steel is impermeable to liquids and vapors, controls undercutting caused by corrosion and offers...

  • Steel Tanks

    Steel Tanks

    Large diameter carbon steel storage tanks are constructed from strip metal wound in a helical path in which the tank is built upwardly. The strip is fed to a support assembly arranged circularly on a base, and the upper edge of the strip that is fed to the support assembly is aligned with the lower edge of the helical turn immediately thereabove so that the edges are spaced apart in a vertical plane from each other and then butt welded together. The...
