72 m³/day reverse osmosis for SAIV’s agribusiness
We designed, supplied, installed and commissioned a microfiltration, ultrafiltration, softening and reverse osmosis system that turns deep well water into 5 to 7 µS/cm water for agro-industrial processes.

1,200 L backwash and CIP tankUltrafiltration, softening and osmosis
Well water with salts and hardness, turned into low-conductivity water
SAIV needed to treat 4.5 m³/h of deep well water with high dissolved solids, hardness and conductivity, and obtain a continuous supply of 72 m³/day of permeate with a conductivity of 5 to 7 µS/cm.
- High hardness177.8 mg/L of total hardness, which scales the membranes if it isn’t removed first.
- Dissolved salts285 mg/L of total dissolved solids and 559 µS/cm of conductivity.
- Continuous supply72 m³/day of permeate with a conductivity of 5 to 7 µS/cm.
From the well to treated waterconductivity on a logarithmic scale, in µS/cm
Ultrafiltration and softening prepare the water so the reverse osmosis membranes work without fouling or scaling.
- 108 m³/dayultrafiltration
- 72 m³/dayreverse osmosis
- 75 %net reverse osmosis recovery
- 5 to 7 µS/cmtreated water conductivity
Treatment train: from the deep well to permeate
Five stages: three pretreatment barriers protect the reverse osmosis membranes, and a daily backwash keeps the ultrafiltration clean.
- MicrofiltrationPolypropylene cartridges in an SS304 stainless steel housing that protect the following stages.From 25 to 1 µm
- UltrafiltrationThree 2860 membranes that retain colloids, viruses, bacteria and suspended solids.108 m³/day
- SofteningTwo fiberglass tanks with SaniExchange +Na resin that remove calcium and magnesium hardness.Membrane protection
- Backwash and CIP1,200 L conical tank on an SS304 stand and a 316L stainless steel vertical multistage pump.Daily backwashes
- Reverse osmosisLow- and high-pressure pumps, automatic antiscalant and pH stabilizer dosing, and 8″ SS304 membrane housings.72 m³/day, 75% recovery
Automation and control
- Horner PLC with 2.2″ HMI screen and IP65 protection rating.
- Online conductivity, pH and ORP at key points in the process.
- Ultrasonic flowmeters, pressure gauges, pressure switches, actuated valves and solenoids for flows and flushing cycles.
- Level alarms
- Motor thermal protection
- Pressure variations
- Out-of-spec ranges
