L Series
- 300 to 19,000 Gallons/Day
- For feed water TDS 500 to 1000 PPM
Designed to produce low dissolved solids water from tap or well water, these Small Commercial RO systems use high efficiency reverse osmosis membranes. Part of the L-series family (other systems include XL and HL series), these RO systems are designed to work at pressures of 200-250 psi for higher TDS water and use TW reverse osmosis membranes. The TW RO membranes offer higher salt removal and the higher operating pressure overcomes the loss of membrane flow due to higher TDS level.
AMI L Series 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.
- Over 40 years of experience is reflected in our quality
- Compact, Heavy Duty, Powder Coated Frame
- Proven components used throughout the system
- Conservatively engineered for reliable long term performance
- Factory tested to ensure trouble-free operation

Notes and Voltage/ Ordering Information
- Recommended Pre-Treatment Equipment: All pretreatment equipment and SDI test kits are available from Applied Membranes.
- Carbon Filter: Chlorine must be removed with a carbon filter prior to the RO system, if present in the feed water.
- Water Softener: Hardness must be removed if present in feed water prior to RO to avoid scaling the membranes.
- Multimedia filter: If feed water exceeds <1 NTU turbidity, or silt density index (SDI) of 3, media filter pretreatment recommended.
- Capacity Basis: 24 hrs/day
- Systems rated at: 77°F (25°C) using 1000 ppm sodium chloride solution operating at approx. 200 psi (14 kg/cm²) pressure. For feed water with higher TDS refer to our Series HL brochure.
- Minimum feed pressure to RO System: 40-60 PSI. System capacity changes significantly with water temperature
- All dimensions and weights are approximate.
- Voltage: Please add our voltage codes to the end of the model number when ordering. Example: L-12521-116 = 110v, 1 ph, 60 hz.
