Filtration-Membrane-Technology Services

Membrane technology is a mechanical separation process utilized to separate gaseous or liquid mixtures and solutions using specialized membranes. Depending on the membrane type, it caters to various separation requirements, offering both economic and ecological benefits through physical separation. The core structure of a membrane involves a support body with a microporous surface, topped by the membrane layer that dictates filtration fineness. In a closed-loop system, the impure mixture flows over the membrane layer, which filters particles larger than its pores, allowing the purified medium to pass through. Different geometries exist for different needs, with elements available as mono or multi-channel with varying diameters, providing up to 211 channels per element in some cases. Membrane processes are classified into microfiltration, ultrafiltration, nanofiltration, and reverse osmosis based on particle size. Various polymeric plastics and ceramics are used as membrane materials, with ceramics often preferred for their longevity and superior mechanical and chemical properties, achieving separation limits from 1 to 1400 nanometers. Applications span environmental technology, water technology, the food and dairy industries, and bio and fine-organic chemistry. Key benefits include definable process separation limits, durable and inert membrane materials, potential chemical-free operation, low operating costs, modular and expandable construction, compact systems with minimal filling volumes, high automation levels, and scalable system capacities, ensuring rapid amortization. For unknown filtration properties, testing is available via laboratory or pilot scale units, aiding in the design of industrial filtration plants.
