Water Technology magazine reports that many customers in both the laboratory and industrial sectors are now looking for sustainable options when it comes to water treatment, including reverse osmosis (RO) systems.Professionals cannot dispute RO’s effectiveness, but they are also aware of the technology’s drawbacks, such as high energy requirements, and product water to wastewater ratio.


Assuming a quality system is purchased and installed by a trained professional, an RO unit’s performance and energy demands should only slightly vary through the course of its life in most standard applications. However, there are certain variables that impact RO technology, including the quantity of permeate water produce, the quality of the water being treated, pressure applied to water/flow rate, water temperature, and total dissolved solids (TDS), among others.


Pressure, measured in psi, is required to push water through an RO membrane in typical residential and light commercial applications. A standard of 60 psi is recommended for these settings and at that flow rate, about 18 gallons of water per day is able to pass through the system. However, new low energy membranes for the residential market are capable of handling up to 150 gallons.


AQUA SOLUTIONS offer various reverse osmosis (RO) pretreatment systems that are based on years of sustainability research. They are available with RO production rates of 10-60 Liters/hour for standard bench top systems, and 1-2 gallons/minute for High Capacity frame mounted systems. The systems remove 95-99% of the contaminants in tap water, representing a cost-effective technology for pre-treating tap water prior to final purification by a DI system.


They operate on tap water with up to 1,000 PPM total dissolved solids (TDS), and most systems include built-in pre-filters. A variety of storage tank options are available including pressurized tanks that prevent the risk of airborne contamination and eliminate the need for additional feed pumps.


Although a highly effective technology, RO’s energy and wastewater drawbacks have the potential to concern some customers. AQUA SOLUTIONS recognizes these, and developed RO systems with minimal impact on the environment.
