Multi grade filters are water purification filtration systems employed in removing solid particles, dirt, sand, and other physical contaminants from water. This involves the use of different grades of filtration media with varying sizes of particles in order to ensure efficient depth filtration. These filters find great application as pre-filtration systems in water treatment plants and industrial RO plants, among others.
A multi-grade filter (MGF) is a pressure filter with several layers of filtration media within it. Water is passed through the media, and particles are trapped at different levels of the filter. The media can be sand, anthracite, garnet, or supporting gravel. The filter has multiple layers, allowing more contaminants to be effectively treated without affecting the water flow rate.
When functioning normally, water passes into the Multi-Grade Filter from above downwards through various layers of filtration media. Large particles are caught by the upper layers of the media, whereas smaller particles are trapped by the lower layers. In the course of filtration, the impurities start accumulating in the media. Once the pressure drop reaches the desired point, the backwash cycle starts. In the process of backwashing, water runs in the opposite direction to clean the media from impurities.
Thus, the ability of the Multi-Grade Filter to carry out filtration is restored.
Our industrial multi-grade filters are intended to provide reliable filtration and extended service life. These features are:
The filtration unit can be customized for water quality, flow rates, operating pressure, filtration requirements and other conditions.
Multi-grade water filters are frequently used as a pre-treatment system in industry and commercial water treatment applications. The multi grade water filter is ideal to be used in Industrial RO systems, water treatment plants, cooling water treatment systems, process water treatment systems, and general filtration purposes. Industries including pharmaceuticals, chemicals, food and beverages, textiles, power generation industries, manufacturing industries, and engineering sectors can utilize a multi-grade filtration system to minimize suspended impurities in water before other water treatment processes.
The choice of Multi Grade Filter is dependent upon many parameters, including but not limited to quality of source water, concentration of suspended particles, desired flow rate, pressure of operation, filtration velocity, and further processing needs. Our Multi Grade Filters have been developed keeping in mind the following aspects of the filtration process: efficiency, ruggedness, simplicity of operation, and reliable performance.
The multi-grade filters represent a feasible way to eliminate suspended particles and turbidity from the water. In addition, using multi-stage filtration medium, efficient backwashing, and customized configuration, these systems may act as a pre-treatment stage in the water treatment process at the industrial level. A well-designed multi-grade water filter will help improve the quality of water, protect the equipment downstream, and ensure the effective performance of water treatment systems.
