Ecosoft MO-3 is a fully automated 3…4 m3/h reverse osmosis system. It is pre-engineered and pre-fabricated at the Ecosoft factory for turnkey delivery, installation, and commissioning at your site. The product water is delivered in continuous 24-hour service. System maintenance (see Operation and Maintenance tab) will be required every few weeks in most operating environments.

The main equipment includes:
— Grundfos® high pressure pump
— Dow Filmtec™ membranes
— Ecosoft process controller
— Pressure vessels, valves, and other hardware from EU vendors

Most necessary instrumentation is built-in. Additional plug-in equipment, membranes, and consumables are linked at the bottom of the page. Feel free to reach us out for more detail on this product!

PROCESS FLOW DIAGRAM


Технологическая схема MO33XLWE (en)


Operation:

Feed water goes through sediment prefilters to remove particles.

If using antiscalant for hard water then it is injected before the prefilters, so the chemical is mixed with water more thoroughly. 

High pressure pump feeds the prefiltered water into the membrane array. Inside the membranes, feed water is separated into purified water (permeate) and brine with retained impurities (concentrate). 

Ecosoft RO systems feature built-in concentrate recycle, sending part of the concentrate back to the pump. Recycle flow control and drain flow control work to sustain the operating pressure and the recycle/waste ratio. 

Operating pressure is variable within allowed range. Higher pressure produces higher permeate flow rate and/or recovery. Proper operating pressure and recycle/waste must be set up during commissioning. 

Ecosoft RO system runs in a completely automated fashion. The system stops to standby when pure water tank is full. Automated membrane rinse occurs every time before standby, with preprogrammed intervals during standby and service. 

If any of below conditions occur, the system switches off and displays failure alert: 

iso-exclamation-warning-symbol-is-2002(1).png low feed water pressure
iso-exclamation-warning-symbol-is-2002(1).png high operating pressure
iso-exclamation-warning-symbol-is-2002(1).png high permeate conductivity
iso-exclamation-warning-symbol-is-2002(1).png phase or voltage failure

Maintenance:

  1. changing out expendable filters in pre-filter housings
  2. chemical clean (CIP) the RO membranes when signs of membrane scaling or fouling arise; those include lower permeate flow rate or higher permeate conductivity 10% or more; normally, CIP lasts a few months before another CIP is required
  3. if CIP fails to restore membrane flux, the membrane elements need to be replaced;
  4. whenever an extended downtime is to happen, the membranes should be rinsed and soaked in preservative solution

Important precautions:

  • Carefully read the instruction before operating the unit.
  • Only use piping of equal or larger diameter than the RO system's inlet and outlet ports. Avoid long runs of small diameter pipe.
  • Only use equal or larger diameter point-of-entry filters to provide maximum influent water flow rate. 2,5×10 size filters only have up to 1-2 m³/h capacity (5-10 gpm) and should not be used for this Ecosoft RO system.
  • Membranes are shipped in original packaging and must be installed before operating the system. O-ring seals on the membranes must be on the feed water side of the pressure vessel.
  • Remove plastic wraps from filters before installing them in pre-filter housings.
  • Make sure feed water is supplied to the system at required pressure before starting up the system.
  • Check Lovato protection relay when connecting power to the cabinet. Red light or flashing green light signals phase failure or abnormal voltage conditions as per instruction.
  • Do not use brass, iron, or copper pipe for permeate plumbing.
  • During first run, concentrate flow rate, recycle flow rate, and the operating pressure must be adjusted with the flow control valves. The operating pressure must not exceed 12 bar. The ratio of permeate flow rate to drain flow rate must not exceed 0.75.
  • It is advisable to supply influent water using a feed water tank and pump, and to deliver permeate using permeate tank and pump.
  • Keeping a repair kit is advised.
