Ordering Information for HL Series High TDS Commercial RO Systems

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.

Softeners & Media Filtration Pre/Post Treatment

AMI Media filters feature fully automatic backwash or regeneration for easy, trouble free maintenance. Ensure superior system operation and extended membrane life by providing proper pretreatment to the incoming feed water on a continuous basis. Common pretreatment or post-treatment methods include:

• Single or Twin Water Softener to remove hardness and scale.
• Multi-Media Filter for sediment filtration to approximately 10 microns.
• Carbon Filter to remove chlorine.
• Calcite Filter to neutralize the pH of the RO product water.
