Membrane systems provide state-of-the-art technology for many applications in surface treatment and metal finishing where the separation of solids/oil water is required.
A semi-permeable membrane is used to remove solids and dissolved substances with a specific molecular weight from the contaminated liquid. Belmar utilises the advantages of different membrane materials and available pore sizes to achieve a maximum of process performance and reliability. Our membrane systems utilise cross flow filtration in which the flow of contaminated liquid is parallel to the membrane surface. This allows the clean water phase (permeate) to pass through the membrane while minimizing fouling of the membrane surface. The result is a long lasting filtration surface that is cleanable and can be reused many times.
Ceramic Membrane Systems
Our membranes systems use two main types of membranes, Ultrafiltration & Microfiltration Membranes. Belmar’s ceramic membrane filter elements are made of pure α-Al2O3, the chemical stable variant of alumina and the membranes consist of Al2O3, ZrO2 or TiO2, depending on pore size. The ceramic membrane filter elements can be produced with a wide range of pore
sizes covering the whole range of micro- and ultra filtration.
The tube shaped mono- and multi channel filter elements are suitable for applications under abrasive and chemical aggressive conditions. Belmar filter elements have an outstanding filtration efficiency at high flux values, e.g. for oil water separator applications.
