Multigrade/Pressure/Dual Media

Our company is a prominent manufacturer of multi grade filter and provides engineering services from designing, manufacturing to installation and commissioning. Our Multigrade sand filtration plants are designed to meet specific requirements of our customers; no matter what quality of water you use and what your flow rate requirements are, our engineering team is capable of configuring the same accordingly, we can manufacture and supply any capacity you need.

Note:Lower or Higher flow vessel design will be provide as per demand of Client

Working Principle

A latest concept in the water treatment technology, a Multi Grade Filter consists of vertical or horizontal pressure sand filters that contain multiple layers of coarse and fine sand (pebbles and gravels) in a fixed proportion. It is a kind of a deep filter bed with adequate pore dimensions for retaining both large and small suspended solids and un -dissolvedimpuritieslikedustparticles.As compared to conventional sand water filter, this Multigrade filtration system works on higher specific flowrates.

It is also a low-cost pre-treatment system for ion exchangers (deionizer and softener) and membrane systems such as reverse osmosis etc. With high throughputs, high dirt- holding capacity and capacity to reduce turbidity and TSS (< 20 ppm) from water, it protects ion- exchange resins and membranes from physical fouling due to suspended impurities present in the water. The next and last step is backwashing, a process of effectively removal of captured contaminants from the mediabed.
