  • Page 10: Product Overview

    Product overview Model overview The MLRO 2000 and 3000 RO-system removes (>95%) of salts and minerals from the RAW water. The main system components are fitted on an ‘easy-to-place’ base frame (pump skid), the tank that holds 1000/265 liter/gal are placed the on a separate frame, and are normally placed beside the pump skid. There are two pumps on the pump skid: The RO pump which pumps the raw water through the RO membrane at and into the RO water tank.

  • Page 13: Functional Description Ml Ro

    Functional description ML RO Osmosis is a natural phenomenon which can be defined as the movement of pure water through a semi permeable membrane from a low to a high concentration solution. The membrane is permeable to water and some ions but rejects almost all ions and dissolved solids. Reverse osmosis is a process which occurs when pressure, greater than the osmotic pressure, is applied to the concentrated solution.
