Water treatment plant RO membrane filter cartridge elements Reverse osmosis membrane replaced
Product Description
Each membrane element is housed in a durable, chemical-resistant wrap that ensures stability under varying pressures and temperatures. With consistent salt rejection rates (up to 98.5%) and a high permeate flow rate, our RO membrane cartridges are ideal for applications that demand purity, efficiency, and reliability.
STARK provides a wide range of configurations—including 4040 and 8040 sizes—suitable for small commercial RO systems to large-scale municipal water plants. Each membrane undergoes quality control testing to ensure performance consistency before shipping.
Whether used as a replacement cartridge or as part of a new installation, STARK’s membrane elements are designed to integrate smoothly with standard reverse osmosis systems, offering minimized downtime and easy replacement procedures. The membranes are suitable for brackish water, tap water, and pre-treated seawater systems.
Industries we serve include pharmaceutical manufacturing, food & beverage processing, electronics production, and municipal drinking water treatment. The cartridges also support custom OEM/ODM requirements to match specialized RO system designs.
