How Damo PV Membrane Technology Works

Damo PV membrane is a high-efficiency separation technique that enables molecular separation. Small molecules selectively pass through the membrane, while larger molecules have difficulty permeating it. This results in efficient separation between molecules. In this project, water molecules (0.29mm) are smaller than the organic solvent molecules (ether), and the inorganic membrane pore size is between these two sizes. This allows for efficient separation of water molecules from the organic solvent mixture, yielding ultra-low water content organic solvent products.

Benefits of Pervaporation Membrane Separation Solution

High efficiency and energy-saving

The technology boasts a high single-pass recovery rate, with permeate recovery and utilization reaching over 99%. Compared to traditional distillation and adsorption technologies, it can save 30-50% more energy.

Environmentally-friendly

No third component is required, and the permeate can be recycled and reused, minimizing waste and reducing environmental impact.

Safe and simple

The process is controlled and monitored automatically through PLC and HMI systems, with a safety interlock protection system ensuring a high level of automation and safety.

Skid-mounted equipment

The technology takes up minimal space, is easy to install and maintain, has low equipment height, and features a modular design for simple maintenance without the need for extensive infrastructure.
