Lithium Refinery Leverages Dilute Process Solution for Production of Lithium Carbonate with SAMCO High Pressure RO System

Project Overview

At a leading lithium refinery in Quebec, Canada, lithium carbonate production lines demanded a consistent supply of concentrated lithium bicarbonate solution. Applying seawater filtration membrane technology, SAMCO delivered a high pressure reverse osmosis (RO) system to reliably support client production.


Concentrate dilute lithium bicarbonate solution to near saturation for downstream lithium carbonate production. Specifications:

  • Input rate of 130 GPM
  • Output rate of 40 GPM

Scope of Service

SAMCO delivered a turnkey RO system, with services comprising comprehensive process, mechanical, and electrical design and engineering, system fabrication, commissioning, startup training and support.


  • Produce highly concentrated solution
  • Integration with existing distributed control system (DCS)


In line with the client’s needs, SAMCO designed and delivered a high pressure RO system to produce a highly concentrated solution for downstream lithium carbonate production. The design made use of high pressure seawater filtration membranes to sustain both long term reliability, and efficient 40 GPM output of a nearly saturated lithium bicarbonate solution. The project solution entailed a prepackaged design and comprehensive support, ensuring quick delivery and fast startup. Entailing a backwashable tubular filtration unit, RO unit with seawater membranes, and peripherals, the system also included terminal boxes for optimal integration with the client’s existing DCS.


Project deliverables and equipment included:

  • Backwashable tubular filter unit
  • RO unit with seawater membranes
  • Pipe rack assemblies
  • Instruments and valves
  • High pressure pump
  • Auxiliary tanks and pumps
  • DCS-ready terminal boxes
