FAQs
Will installing Hydroxyl upstream of a carbon tower or RO membrane void the manufacturer’s warranty?
No — installing Hydroxyl upstream of a carbon tower or RO membrane should not, by itself, void a manufacturer’s warranty. Hydroxyl is installed as an external pretreatment device and does not modify the carbon vessel, membrane housing, membrane element, controls, pumps, or internal components. It is designed to operate within the customer’s existing flow, pressure, temperature, and water-chemistry specifications. Under U.S. warranty law, a manufacturer generally cannot deny warranty coverage merely because a customer used a third-party product or add-on.
Where is Hydroxyl installed in an RO system?
Hydroxyl is typically installed upstream of carbon towers, filters, RO feed pumps, or RO skids to improve the pretreatment environment before fouling reaches the membrane.
Does Hydroxyl replace existing pretreatment chemistry?
No. Hydroxyl is designed to enhance existing RO pretreatment programs, not replace the entire treatment train.
Does Hydroxyl require external gas or consumable media?
No. Hydroxyl systems do not require external gas feed systems, salt, resin, membranes, or sacrificial treatment media.
Can Hydroxyl be used in potable water applications?
Hydroxyl systems can be specified with NSF/ANSI 61 and NSF/ANSI 372 compliant wetted components for potable water and high-purity industrial RO applications.
Is Hydroxyl skid-mounted or integrated into existing piping?
Hydroxyl systems can be supplied as complete skid-mounted packages with properly specified pumps or integrated directly into existing RO infrastructure.
Does Hydroxyl require major plant modifications?
No. Hydroxyl is designed for retrofit installation into existing RO pretreatment systems. Depending on site conditions, systems can typically be installed with minimal piping modifications and minimal disruption to plant operations.
Is Hydroxyl designed for continuous operation?
Yes. Hydroxyl systems are designed for 24/7 operation in industrial water treatment environments with minimal maintenance requirements.
Is Hydroxyl a membrane-contact oxidant injection system?
No. Hydroxyl is designed as an upstream pretreatment enhancement system, not a membrane-contact oxidant injection system. The goal is to improve the pretreatment environment before fouling reaches the membrane.
What operating data is typically reviewed during a Hydroxyl deployment?
Typical performance indicators include RO differential pressure, permeate flow, feed and permeate TDS, rejection percentage, cleaning frequency, cartridge filter changeouts, chemical usage, membrane condition, and downtime related to fouling.
