HL-ROS Brochure

Product catalog summary

Overview: The document describes the HL-ROS Series Fresh Water Makers, which are designed for desalination using reverse osmosis technology. These systems are capable of producing between 3 to 48 tons of fresh water per day.

Specifications: The system utilizes the latest generation TFC® membranes and features a high-pressure axial piston pump that operates without lubricating oil. It includes a variable frequency drive and is designed for 24-hour constant operation. The system is compact, allowing for variable positioning of membranes to save space. Standard features include chemical cleaning fittings, prefiltration filters, and an automatic fresh water flush with an integrated dechlorination filter. The operation is semi-automatic and PLC controlled, with a corrosion-resistant frame and components.

Process Description: The reverse osmosis plant operates as a single-stage, single-pass desalination system. Seawater is supplied by a pump that raises the pressure to approximately 3 bar before entering the pretreatment section. Pretreatment involves a bag filter to remove particles larger than 25 µm, followed by a 3 µm cartridge filter. The treated water is then fed to a high-pressure pump, which increases the pressure to a maximum of 69 bar. The system pressure and product flow rate are controlled by a pressure control valve. Product water is collected from the membranes and delivered to storage tanks. An optional remineralizer can adjust the pH to potable water standards.

Flow Diagram Components: Key components include a fresh water source, carbon filter, 3 µm filter, 25 µm bag filter, optional 200 µm bag filter, cleaning tank, seawater pump, seawater inlet, product water tank, regulation valve for concentrate flow, RO membrane system, high-pressure pump, and concentrate discharge.
