The basic principle of ultra-fine filtering membrane technology is the use of pressure to separate dissolved ions from water through a semi-closed membrane. It operates under different hydraulic specifications which is also known as vertical flow filtration, in contrast to the clog filter theory.
Most of the microfiltration membranes are composite materials and are manufactured in a helical design rather than flat membranes. Like the prevailing model today, which represents the best methods used for industrial plants, it is the use of helical design membranes.
Microfiltration in water treatment, or nano-membrane reverse osmosis membranes. It is sometimes referred to as a reverse osmosis membrane or a bottom reverse drainage. It may also be called ultra-filtration, as the size of the pore size of the nanoparticle ranges from 0.01 to just under 0.001. In general, the nanofiltration membrane system enables less salt passes than the reverse osmosis membrane. In addition, the nanofiltration membrane component will produce the same amount of product at 50 to 70% of the applied pressure as the reverse osmosis water treatment system.
The 75% salt infusion ratio is from 95% to 99%, especially when this is achieved using only half the energy. In contrast to the reverse osmosis membrane, the manufacturers' nanofiltration offerings of the membranes differ completely in performance from one company to another. Comparison ب ، Any sample NaCl rejection ratio is less than 99.5%, especially with seawater membranes, and is considered less important. Compared to nanofiltration, there are differences for any membrane with a NaCl rejection rate of 40%, or more. Nanofiltration is also called a resistive membrane, while the salt discharge may be 80% or less, the salt rejection often remains above 90%. Like reverse osmosis, and unlike ultrafiltration, nanofiltration systems will recover a proportion of the desalinated water. Most of the nanofiltration membranes are spiral-shaped.
Other uses of a microfiltration system are:
إزالة المبيدات من المياه الجوفية
Soften water and remove nitrates
Ramdoun Group designs and manufactures an integrated line of industrial nanofiltration devices and systems, or so-called microfiltration systems, which are designed using the latest advanced technology for 3D computer programs and a design process for precise and specialized solutions.

Industrial Nanofiltration systems from Ramdoun, which are based on the use of the latest membranes for very fine filtration, and are often used to reduce the group of dissolved solids in water such as surface water and fresh groundwater, as well as for the purpose of water hardness (removal of large positive ions with double valence) as well as for the removal of organic matter. Natural and synthetic organic materials.
