Harn R/O Systems, Inc. has forty years of experience in the design, manufacture, installation and maintenance of reverse osmosis water treatment systems, producing systems for numerous applications, with capacities of up to 12 million gallons per day. Our success with these large, sophisticated systems is due in large part to our ongoing commitment and involvement with pilot systems.

Harn R/O Systems, Inc. has designed and manufactured numerous pilot systems, including brackish R/O, membrane softening, membrane filtration (micro and ultra filtration) and seawater desalination. From 1,000 gallons per day (GPD) production capacity to over 20,000 GPD, pilot units can be provided to test single elements or full scale system design utilizing full length vessels in two or three stage configurations. Our understanding of the goals of pilot studies and our experience with the operation of pilot systems makes us uniquely qualified to design and manufacture pilot systems that are reliable, “operator-friendly”, and provide quality data.

Pilot studies are invaluable to establish and optimize design parameters such as feed pressure, recovery, flux, chemical dosages, and recommended cleaning frequencies. Pilot studies may also be necessary to fulfill regulatory requirements such as the EPA Information Collection Rule.

Pilot unit installation and start-up services are available. Technical assistance and data evaluation will be provided during the study. Harn R/O staff has many years of experience in pilot studies, design and manufacturing of reverse osmosis and membrane softening treatment systems. Our technical staff will be personally involved during the study, enabling the customer to utilize the resources of our experience for the benefit of the project.

Please allow us to support you in evaluating your pilot study requirements. Please contact us if you like to lease or purchase a pilot unit.
