Membranes

Membrane separation technology is a new type of separation and purification technology that utilizes the principle of screening and cross flow filtration. It has the characteristics of low-temperature operation, energy saving, high efficiency and precision molecular level separation. The products are divided into various types according to their structural forms, such as roll, tube, ceramic, hollow, etc.;

Separation precision includes microfiltration, ultrafiltration, nanofiltration and reverse osmosis, which are widely used in metallurgy, environmental protection, pharmaceuticals, chemicals, food and others..

Advantages of SmarSEP’s ceramic Membrane product

1. Complies with FDA certification and EU 3A sanitary material certification.

2. High separation precision, one-step ultrafiltration, to replace the traditional ceramic MF + organic UF processes, resulting in a 1-2% increase in product yield.

3. The traditional ceramic membrane filtration layer is uneven and cause filtration permeate’s quality is bad, which leads to frequent cleaning and regeneration of subsequent organic membranes and resins process, and a short lifespan. The use of high-quality ceramic membranes can significantly prolong the service life time of subsequent nanofiltration membranes and resins.

4. The average flux of membrane is high, and the single unit installed filtration area is large, which can significantly reduce unit energy consumption and reduce the water consumption for cleaning and regeneration.

5. High quality ceramic are preferred for their high mechanical strength and long service  life time.

Spiral wound nanofiltration membrane element

The filtration precision of NF membrane is between reverse osmosis and ultrafiltration membrane, and the molecular weight cutoff is about 200-800MW. There are three common specifications of membrane tubes: 2540, 4040, and 8040. Nanofiltration membrane materials mainly include: polyamide (PA), polyether sulfone (PES), polypropylene (PP), polyester (PET), and polyurethane (PU). Polyvinylidene fluoride (PVDF), mainly NF element material is polyamide.

NF process can be widely used in industrial fields such as decolorization, concentration, separation and purification.
