Water Challenges: The challenge of this project was supplying water treatment solutions for the reuse of treated wastewater effluent by removing unwanted ammonium in wastewater treatment pilot plants. Water purification is needed to completely remove harmful substances from the wastewater that has already been pre-treated to reuse for certain applications. Without the necessary treatment, the reclaimed water will remain dirty and polluted, which can lead to health concerns and low-quality performance. While ammonium is not a dangerous element for humans, it does pose a significant threat to aquatic life.


Applied Solution: Pure Aqua manufactures custom-engineered wastewater treatment technology that provide the purification needed to remove unwanted contaminants from the water streams that are used by various industries. Our treatment technologies consist of pilot seawater systems that are designed to eliminate high concentrations of ammonium within treated wastewater effluent. These seawater membranes are also capable of eradicating other substances such as salts, proteins, sugars, bacteria, viruses, and constituents that contain a larger molecular weight of 150-250 Dalton. Pure Aqua’s engineering team are passionate about supplying a comprehensive line of standard and customizable seawater reverse osmosis systems, all of which incorporate cutting-edge 3D computer modeling and advanced features for accurate and tailor-made solutions.


Ammonium Reduction in Wastewater Ammonium salts does not cause an RO scaling problem. The ammonium ion is the result of very soluble gaseous ammonia (NH3) being dissolved in water. Non-ionized ammonia ionizes in water to form the ammonium ion and hydroxide ion. The degree of ionization of ammonia to ammonium is dependent on pH, temperature, and the ionic strength of the solution. At higher pH the ammonia gas is prevalent, and being a gas, will not be rejected by a RO (similar to carbon dioxide gas). At lower pH the ammonium ion is prevalent and is rejected by a RO.
