High TDS RO 300 to 9,000 GPD

HL SERIES – HIGH TDS RO SYSTEMS 300 TO 9,000 GPD

  • 300 to 9,000 Gallons/Day Reverse Osmosis Systems
  • For Feed Water TDS 1,000 to 5,000 PPM

Designed to produce low dissolved solids water from higher TDS tap or well water, these Small Commercial RO systems use high efficiency, thin film reverse osmosis membranes and FRP membrane housings. The RO product water is used in applications such as water stores, whole house, ice makers, humidification, misting, and a wide variety of other applications.

Part of the L-series family (other systems include L and XL series), these complete, high TDS RO systems use corrosion resistant materials for all high pressure lines and components. The operating pressure is between 200 and 250 psi. Careful design steps are taken to minimize the highly corrosive nature of these brackish waters.

These reverse osmosis systems use the proven, reliable components and are mounted on a sturdy powder-coated metal frame. There are numerous design details learned from years of experience that are incorporated in our water filtration systems. Our process and fluid design ensures an optimum membrane life and minimizes the membrane fouling.

Notes and Voltage/ Ordering Information

  • All dimensions and weights are approximate.
  • Capacity Basis: 24 hrs/day
  • Systems rated at: 77°F (25°C) using 1000 to 5000 ppm sodium chloride solution operating at approx. 200-225 psi pressure.
  • Minimum feed pressure to RO System: 40-60 PSI. System capacity changes significantly with water temperature
  • Chlorine must be removed with a carbon filter prior to the RO system, if present in feed water.
  • Pretreatment for water hardness using a softener or antiscalant injection should be added to avoid scaling the membranes.
  • Feed water turbidity: Less than 1 NTU; Feed water silt density index (SDI): 3 maximum. If exceeded, pretreatment with media filter recommended. All pretreatment equipment and SDI test kits are available from Applied Membranes.
  • Voltage: Please add our voltage codes to the end of the model number when ordering.
    Example: HL-12521-116 = 110v, 1 ph, 60 hz.
  • Voltage Codes:
  • 116 = 110v, 1ph, 60hz (up to L-24A only)
