Features

  • Capacities from 18,000 to 270,000 gallons per day and above suit a wide variety of applications.
  • Spiral wound, thin film composite membranes provide superior salt rejection and product flow at low operating pressures.
  • Computerized system design accurately projects system operating characteristics for each application.
  • Multistage centrifugal pumps supplied with stainless steel and Noryl wetted parts for corrosion resistance and and offer quiet, high-efficiency operation.
  • Cartridge pre-filter – all polypropylene or stainless steel for corrosion control. Five or one micron filter elements included.
  • Control panel – NEMA 4 control panels include digital conductivity monitor, programmable controller, tank level control, fuses, motor starter, switches and control transformer. ORP, pH and totalizing flowmeters optional.
  • Control valves – pump and reject throttle valves are included for flow and pressure control.
  • Automatic flush reduces corrosion potential and membrane fouling.
  • Liquid-filled pressure gauges assure pulse-free readings and long gauge life.
  • Line-mounted flow meters offer consistent accuracy and corrosion-free performance.
  • Convenient layout – all gauges, meters and controls are located next to the control panel for ease of operation.
  • Feedwater control valve automatically shuts off feedwater when system is not operating.
  • Low pressure switch protects the pump from damage caused by inadequate pump inlet pressure.
  • Fiberglass frame assembled with stainless steel hardware for total corrosion control.
  • Standardized system design allows for quick shipments, yet adaptable to suit individual application requirements.
  • Expandability – systems can be expanded to meet future requirements.
  • Quality after-sale support – field service personnel assure your system is properly installed and that you remain on-line.

Total system capability

Lakeside Water offers a complete line of options and accessory equipment to complement the LTF2, LTF3, and LTF4 Series RO Systems. They include the following:

  • Ultra low pressure membranes - reduce power consumption by 30% or more,
  • Membranes - alternate membranes including nano-filtration (NH), seawater (SW), cellulose acetate (CA) and softening membranes are available,
  • Two-pass RO - produce ultrapure water at low cost.
  • Pretreatment equipment - filters, softeners, chemical feed systems, UV sterilizers, ultra-filtration (UF) and microfiltration (MP) systems are available to prevent scaling and fouling the RO membranes.
  • Post treatment equipment - degasifiers, chemical feedsystems and UV sterilizers are provided to assure that the product water is within specifications.
  • Deionizers - polish the RD product water to meet application specifications including ultrapure water.
