We live in a true water world, with over 70% of the life-giving liquid covering the planet. Yet with all that H20, only about 2.5% of the world’s water is freshwater (drinkable) – and two-thirds of it is frozen in the world’s glaciers.
There is a premium on clean, healthy drinking water and there are certain steps necessary for ensuring a constant flow of this vital resource. For the companies and organizations serious about meeting health standards and procuring high quality drinking water, there are several methods of filtration they ought to consider.
Types of water problems in Minnesota.
Southeastern Minnesota’s water is notorious for having an unusually high concentration of iron. Apart from that, a looming problem of excessive nitrogen in lakes and streams is also a cause for concern.
To stay ahead of health hazard and headache, it helps to have a proper filtration plan in place. Part of that plan starts with recognizing which filtration type is right for your organization.
To choose the commercial filtration system that’s best for your business and budget, you will need to know your system’s flow rate and backwash rate requirements. Likewise, it will help to know the specifications and limitations of each. A certified filtration systems expert can help you choose the best possible option.
Types of Water Filtration.
Iron Curtain Filtration
Designed to remove ferrous and ferric iron without the use of chemicals like potassium permanganate, chlorine or salt, an iron curtain filtration system can lower operating costs and problems associated with hazardous chemicals. It can help omit iron stains, an iron taste to your water, and that rotten egg smell.
By forcing mineral rich water through the pressurized tanks, tiny particles are created which grow large enough in size to be easily removed by the filter system. The iron curtain filtration system is rated for continuous flow rates from 2.7 gpm to 476gpm at 5/gpm/sq. ft.
This type of filter allows for much faster flow rates than a conventional sand filter. Through an almost reverse-like process, lighter weight particles float to the top and the more coarse particles go to the bottom.
An upward flow of water through the filter bed allows for catching contaminants and providing a greater quality and quantity of water. Smaller diameter tanks can be used for greater flow rates.
Sand Filter Systems
This type of depth filter system uses sand to capture the free radicals and pollutants.
The more conventional means of residential filtration, a slow sand filter system can help remove disease-causing organisms and keep water clean for usage. A biolayer typically forms at the top of the sands and gravel layers, which contributes to the cleaning process. Over time, it is possible for the flow rate to decrease so it’s important to have a routine maintenance visit in place.
Standard filter systems are available from 10’’ – 72’’ diameter vessels, with both single and multiple tank configuration options. Hellenbrand system designs include: Single Tank Top Mount or Side Mount; Available with 1.25″, 1.5″, 2.0 ” and 3.0″ Smart Controllers
This type of filter relies on a special granular media called Birm, which causes iron particles in the water to rust when ample oxygen is made present. Birm allows for the reduction of iron and manganese compounds. This system only requires periodic backwashing and can deliver a quality end product.

A Filter-Ag is used for suspended solids reduction. The larger particle size in the system allows for less pressure loss and ultimately, a high quality water filtration. Its lightweight and economical process allow for some substantial savings in operation and maintenance costs.
