4 Facts About Amiad Automatic Screen Filters

If you are looking for the newest, most advanced water filtration system, Amiad automatic screen filters are the market leaders.

With sources of high-quality potable water diminishing, there is a huge demand for clean potable water. The problem is the easily available water is non-potable fresh and reclaimed water, commonly used in irrigation. This water is clogged with silt, sand, organic matter and clay particles. Attempts to filter this type of water can easily clog up your filtration system and render it useless or curtail its performance. The result is an uneven distribution of water to your crops. At worst, it can grind your entire irrigation system to a halt.

Not so with Amiad automatic filters.

A manually maintained filtration system is time and labour intensive. The solution is an automatic filtration system such as Amiad, which in addition to self-cleaning capabilities is highly water-efficient since it applies the exact amount of water. The result is reduced water and labour costs. Besides, as opposed to a manual filtration system, you don’t have to waste copious amounts of water to manually clean and flush your filtration system.

And why should you adopt the Amiad filtration systems? Why do I think they are the best in the market? To answer these questions, let’s look at some features of Amiad automatic screen filters that make them a cut above the rest.

1. The Filtration Process

Raw water enters through the filter’s inlet. As it goes through the coarse screen, it arrests sediments and large debris. The water continues to flow past this filter and through the inner fine screen. Smaller particles that passed through the coarse screen are arrested at this point. If there is pressure caused by debris that has accumulated on the inner screen, a differential pressure switch (DPS) initiates the self-cleaning process, an internal cleaning mechanism that gets rid of debris buildup.

2. Amiad’s Self-Cleaning Process

As mentioned above, Amiad’s self-cleaning process is activated by a differential pressure switch that reacts to pressure build up on the inner screen. Once activated, the flush valves open to cause a strong back-flush stream that activates a powerful suction force at the scanner nozzles, sucking out the remaining dirt particles from the screen and ejecting them out of the filter. As the backwash water flows through the hydraulic turbines, they force them to rotate and the scanners to spin.

Consequently, the dropping pressure of the pistons compels the suction-scanners to move axially. The combination of axial movement and spinning forces the suction-scanners to move upward. As they do this, the nozzles thoroughly clean the fine screen’s inner sides; and as water is sucked backwards, any filter cake remaining on the screen is driven out via the flushing valve.

3. What Makes Amiad’s Suction-Scanning Technology Unique?

Amiad self-cleaning filters feature a unique suction-scanning technology that uses less than 1% of water but cleans 100% of the screen area. Depending on conditions of application, no other automated self-cleaning water filtration system in the market can match this efficiency.

4. Economical and Cost-Effective

Another attribute that sets Amiad automatic screen filters ahead of the rest is their efficient use of water. The self-cleaning mode is activated only when debris accumulates to form a filter cake on the surface of the screen. Upon detecting the filter cake, the differential pressure switch activates the self-cleaning process. This means cleaning is done “as needed”, a factor that saves a lot of water and energy. You can channel the resultant savings to other core areas of your operations.

The suction-scanning technology that Amiad uses features a self-cleaning cycle that does not require filter isolation. Besides, since this system requires minimal exhaust, the self-cleaning process is activated whenever debris build-up is detected.
