Reverse Osmosis Systems

Residential Reverse Osmosis Systems


If you are looking for a solution to treat water in your home, our company will always provide you with several options that suit all conditions, whether the water entering the treatment plant is from river water or from well water, or the incoming water is provided through the local water filtration system, the solution is with the corner stone company Fits all conditions

Reverse osmosis systems for Residential use are designed with capacities suitable for saving water for all house uses. Our systems are characterized by a design that suits the content of salts and organic materials in Iraqi waters. Residential systems are manufactured according to the geographical region, because the water quality varies from one region to another. Our company also has reverse osmosis systems for treating well water for Residential use. There are systems suitable for all levels of salinity (TDS: 1000-25000)

Residential Reverse Osmosis Systems for the City of Basra


Our company has special systems for treating the salinity of the water of the city of Basra, which is characterized by:

  1. high level of organic pollution
  2. And increase the percentage of salts in it beyond the permissible limit for potable water.
  3. High percentage of compounds and chemical elements that cause hardness in the water
  4. The level of salts in the water fluctuates with the seasons of the year

Cornerstone Company produces different sizes of systems that are suitable for the water of Basra to provide potable water.

We also have special systems for treating well water, which is characterized by high salinity

Commercial and Industrial Reverse Osmosis Systems


Reverse osmosis systems for commercial and industrial use are capable of producing under all conditions. Large commercial and industrial systems are designed according to the chemical analysis of the water available for use in the system such as:

  • Systems for producing pure water from well water
  • Systems for producing pure water from river water
  • Systems for the production of pure water fed through the local water supply network
System Name Capacity (L/hr) TDS In (mg/L) TDS Out (mg/L) Dimensions Operation
IND-20 3,000 20-350 1000 – 25000 3 X 0.5 X 1.2 automatic

Potable Water Treatment Plants


Our company designs, manufactures and installs Potable water treatment plants in various sizes. Plants of this type can be built in sizes suitable for supplying water for an entire city.

These plants are designed upon request and according to the specifications of the incoming and outgoing water and the type of treatment required


Water Clarifier


In river water treatment, suspended matter is first removed from the water, which is the first stage of treatment. The process takes place in basins of size and shape that suit the specifications of the water entering the treatment plant and the requirements of the treatment process.

Our company uses different shapes in the design of the clarifier to make the treatment process efficient and economical.

One of the factors that determine the shape and nature of the clarifier :

  1. production capacity
  2. The quantity, size and nature of suspended matter in the water
  3. Method for disposing of sedimentary materials
Conventional Clarifier
Clarifier for the removal of suspended solids that is hard to settle

Demineralized water systems


  • With its ability to produce pure water for laboratory uses and high-pressure steam boilers.
  • These systems operate automatically and reactivate the filter material automatically
  • In these systems, ion exchange resin granules are used to purify water, which are characterized by their ability to remove unwanted materials without consuming these granules.
  • The ion exchange material for each system is chosen according to the nature and level of salts to be removed from the water
  • Ion exchange systems are designed according to the need and capacities that suit the required work
  • Reverse osmosis systems are often used before ion exchange systems to obtain water of very high purity.
  • Whether it is water required for industrial use or for the use of chemical or medical laboratories, our company has the ability to respond to your request and achieve the required specifications.
  • Ion exchange systems can be available in small sizes starting from 500 liters per hour
  • All ion exchange systems operate automatically and do not require intervention in daily operation or reactivation of ion exchange granules.
