Reverse Osmosis


Reverse Osmosis (RO)

Reverse osmosis (RO) is a water purification technology that uses a semi-permeable membrane to remove ions, molecules, and larger particles from drinking water.

The largest and most important application of reverse osmosis is the separation of pure water from seawater and brackish waters. Seawater or brackish water is pressurised against one surface of the membrane, causing transport of salt-depleted water across the membrane and emergence of potable drinking water from the low-pressure side.

Desalination is a process that removes minerals from saline water. Salt Water is desalinated to produce water suitable for human consumption or irrigation. One byproduct of desalination is salt. Desalination is used on many seagoing ships and submarines. Most of the modern interest in desalination is focused on cost-effective provision of fresh water for human use.

Blue Africa Environmental Solutions specialises in the design, construction and installation of RO and Desalination systems. These units can vary from household to large industrial scale systems.


Reverse Osmosis Applications

  • Domestic Systems: Commonly used on improving water for drinking and cooking.
  • Portable Units: A self-contained water treatment plant that can provide potable water from nearly any water source.
  • Production of bottled mineral water: Complete reverse osmosis system including additional water treatment stages that use ultraviolet or ozone to prevent microbiological contamination.
  • Wastewater Purification: In the industry, reverse osmosis units are designed specially to remove minerals from boiler water at power plants to prevent corrosion.
  • Food Industry: In addition to desalination, reverse osmosis is a more economical operation for concentrating food liquids (such as fruit juices) than conventional heat-treatment processes. Its advantages include a lower operating cost and the ability to avoid heat-treatment processes, which makes it suitable for heat-sensitive substances such as the protein and enzymes found in most food products.
  • Boats, Yachts and Cruise Ships: A typical sailboat RO system consists of three major sections: the seawater supply and preliminary filtration, a high-pressure pump, and the RO membrane. Depending on the design of the system, either manual or electrically operated valves are used to control the flow of water through the system.

Containerized Reverse Osmosis Packages

Systems that are manufactured for plants which has shortage of place or mobile operating units which are designed inside a container.

All the mechanical and electrical equipments related to the treatment system being assembled into a container at ready for commissioning condition known as mobile (container) treatment systems. Can be installed anywhere by connecting the inlet and permeate-reject lines and can be moved to another location by disassembling three pipes.

Inside the container type systems, pre-filtration, brackish water reverse osmosis systems, sea water reverse osmosis systems, ultra-filtration systems and waste water treatment systems can be manufactured.

Apart from the treatment systems air conditioning, heat insulation and lighting can be installed.
