When considering a new irrigation filtration system, there are several factors you should look at, mainly a combination of a large, effective filtration area with high cleanability, as well as other key features and overall performance.
How many times have you heard about someone buying a knockoff phone charger, only for it to stop working after a month? Ever bought a gadget from an obscure manufacturer that promised you all the bells and whistles for half the price, but once you got it, you realized it doesn’t do what was promised, or even causes damage?
Now, imagine that happening to your irrigation system. Think of all the time and money literally gone down the drain. It's not just wasted water, but a blocked (or partially blocked) system can have a devastating effect on your crops. Ask yourself if that's a risk worth taking, just to try and save a few bucks on the new filtration system? Is you and your family's financial future worth risking like that?
Before you decide what kind of water filtration system you’re going to choose, consider these 5 essential insights on what specs you should look for and what to avoid.
1. Filtration Quality
The most important aspect of a filter is how well it does its job
Avoid: low-grade filters , that can’t back up their alleged promises with actual facts and results.
Look for: A tried-and-tested filter that can guarantee your desired level of filtration and its integrity. Remember – filtration is your irrigation system’s first line of defense. You want to keep it clean and working, reliably and efficiently.
2. Large Filtration Area
Size matters! Particularly the effective surface area of the filter element.
Avoid: Misleading measurements can imply a very large cylinder filtration element, but in reality, the effective filtration area can sometimes be less than 50% of the cylinder surface. A smaller filtration area means a filter that clogs faster and results in frequent flushing. This translates into large amounts of wasted water and energy loss at higher costs. It might even partially/entirely fail to handle the flow.
Look for: A filtration system with a large and effective filtration area. Filters are designed to support a certain flow rate at a given water quality. The larger the effective filtration area, the higher the flow of poor-quality water can pass through it and be filtered.

3. Cleaning Efficiency
Cleaning efficiency is as important as filtration quality. Poor cleaning capability will eventually cause any filter to clog.
Avoid: An inefficient cleaning mechanism with a large diameter that requires higher pressure and flow to rotate, not leaving enough energy for thoroughly cleaning the filter, increasing the likeliness of clogging. All these may also result in continuous flushing.
Look for: A proven cleaning mechanism with precise controlled movement and high suction forces for optimal performances at minimal pressure, wasted water and energy.
4. Utilization of Water & Energy
The less you use – the more you save.
Avoid: Hydraulic filters that require a higher pressure for flushing, or inefficient turbines that require more water and energy to operate.
Look for: An efficient, automatic filter that flushes at a lower pressure, requires less energy and smaller pumps. It also uses less water for flushing, and when combined with a turbine that needs a small amount of water and pressure to spin the suction-scanner shaft, will ensure efficient, thorough cleaning of the filter screen. These factors translate into lower monthly costs and will end up saving you money.
5. Corrosion resistant materials
If you use the filter in corrosive environments – because it’s not just about water...
Avoid: Metal filters and screens made of low-quality materials or low-grade stainless steel with poor protective coating that corrodes and rust.
Look for: High quality engineering. You can either go for a polymeric body and accessories, or high-grade stainless steel with anti-corrosive coating. If your system requires a metal filter, make sure that the manufacturer pays close attention to the coating process. At Amiad, we are very stringent both about the quality of our anti-corrosive paint, and the application process to the filters themselves. These features will allow you to run salty/aggressive water and chemicals through the system.
When it comes to water filtration, a lower purchase price can very quickly end up being much more expensive. A malfunctioning irrigation system can destroy years of carefully cultivation of trees, result in poor crop yields and even prompting you to buy a whole new system. Any of these risks will end up costing you even more money. The best way to save is to invest in the initial stages, acquiring the most suitable equipment for the job, and in the long run this can turn into considerable savings.
Please note that, if your irrigation system handles corrosive water, or is located in a challenging environment, Amiad’s experts can guide you through the process of finding the best filtration solution, based on the level of salts, chemicals, and acids that will go through your system. With over 57 years of filtration experience, we can help you protect your hard work and investment.
