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 - degasifies, chemical feed systems 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.

Lakeside Water for pure water technology

The LTF2, LTF3 and LTF4 Series RO Systems are just part of the family of water treatment products available from Lakeside Water. We offer complete system capabilities including evaluation and design services, state of the art equipment utilizing membrane and ion exchange technology and expert field service.

Features of Lakeside Water Reverse Osmosis Systems:

  • Capacities from 10,000 to 250,000 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 – stainless steel wetted parts for corrosion resistance and offer quiet, high efficiency operation.
  • Cartridge pre-filter – all polypropylene or stainless steel for corrosion control, 1 micron filter elements included for better membrane protection.
  • Control Panel - NEMA 4 control panels include digital conductivity and flowmeters, programmable controller PLC, touchscreen display, fuses, motor starter and control transformer.
  • Control systems – adaptable to suit customer specifications.
  • Control Valves – pump and reject throttle valves are included for flow and pressure control.
  • Automatic Flush – permeate or feed water flush system (AFS) reduces corrosion potential and membrane fouling.  Permeate flush can extend membrane cleaning frequency and membrane life.
  • Liquid filled pressure gauges – liquid filled gauges assure pulse free readings and long gauge life.
  • Flowmeters – in-line and/or paddlewheel to PLC 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.
  • Feed water control valve – automatically shuts off feed water when system is not operating.
  • Low pressure switch – protects the pump from damage caused by inadequate pump inlet pressure.
  • High pressure switch – protects the 8” membranes from high membrane feed pressure.
  • Standardized system design – allows for quick shipments yet adaptable to suit individual application requirements.
  • Design for expandability – systems can be expanded to meet future requirements.

Optional Reverse Osmosis System Features

  • Fiberglass frame – constructed of structural fiberglass assembled with stainless steel hardware for corrosion resistance and reduced maintenance.
  • Automatic product diversion – directs product water to drain if out-of-spec.
  • Temperature – temperature indicator to monitor the RO feed water.
  • Product pressure switch – protects the 8” membranes from potential high product pressure.
  • Percent rejection conductivity – product conductivity/feed conductivity equals salt passage.
  • Instrumentation – feed water ORP and pre-treat or post-treat pH digital display.
  • Silt Density Index (SDI) – SDI kit determines the suspended solids in the feed water.
  • Clean-In-Place membrane cleaning systems – integral to the RO or portable systems are available.
