Membranes & Membrane Housings

Membranes and membrane housing play pivotal roles in the water industry, serving as integral components in water treatment systems. Membranes act as selective barriers, allowing the passage of water molecules while effectively blocking impurities, contaminants, and other undesirable particles.

Membranes & Membrane Housings

These specialised membrane filters are crucial for achieving high-quality purified water, making them indispensable in processes such as reverse osmosis and ultrafiltration.

The membrane housing provides a secure enclosure for these membranes, ensuring their protection and proper functioning within a water treatment setup. These housings are designed to withstand the demanding conditions of water treatment processes, offering durability and longevity. Together, membranes and their housing contribute significantly to the efficiency and reliability of water purification systems, addressing the stringent quality standards required across various sectors of the water industry, including potable water supply, industrial processes, and wastewater treatment.

Hydranautics’ & Nitto’s experience in membrane technology spans five decades. They remain committed to delivering innovative membrane technologies to meet the growing demand of the separation industry. As a result, they design and manufacture a broad spectrum of reverse osmosis, nanofiltration, ultrafiltration and microfiltration membranes in various configurations and chemistries.
