Types of Commercial Water Filter

A commercial water filter is a great way to ensure that your employees have easy access to clean, safe drinking water. It also helps to reduce costs that would be incurred by buying bottled water.

There are many different types of commercial water filters, including both physical and chemical filtration. Here are some of the more common options:

Reverse Osmosis

Reverse Osmosis is a very thorough water filter that can reduce many contaminants, Commercial Water Filter including lead, chlorine and fluoride. It also filters out dissolved minerals that can affect the taste of food and beverages like coffee, tea, and pasta. Some systems go beyond RO filtration by adding an advanced post-tank filter to address specific chemicals, heavy metals and other contaminants.

This type of filtration system works by using a semipermeable membrane that allows only the smallest molecules of water to pass through, while trapping larger ions and organic materials. This process can be compared to Saran wrap that keeps everything sealed in, and it’s a great way to purify water for industrial uses like printing and other processes that require mineral-free water.

Aside from removing harmful contaminant molecules, reverse osmosis also makes your tap water taste better. Blind taste tests have shown that reverse osmosis water is preferred over regular tap water for its clean and fresh flavor. It gets rid of traces of sulfur, chlorine, nitrates and other molecular compounds that cause unpleasant and even toxic tastes.

Unlike other water filtration systems that require you to change filters often, a reverse osmosis system is permanent and fits under your sink. The best systems use an app to monitor the status of your water quality and let you know when it’s time to replace a membrane. This way, you never have to worry about finding a replacement cartridge and reduce plastic waste.

Carbon-Based Filtration

Activated carbon has a knack for absorbing toxins and impurities. Swallow a charcoal pill, and it’ll detoxify your gut; add a carbon water filter to a home system, and it’ll remove bad tastes and smells and reduce chlorine levels. Carbon filters work through a process known as adsorption, where organic compounds stick to the surface of carbon like Velcro. Chlorine, however, does not adhere to the carbon and is instead removed by a chemical reaction called catalytic reduction.

The type of carbon used in a filter determines the quality of its filtration. Coconut shell carbon, for example, is more sustainable than bituminous coal and doesn’t contain traces of arsenic, which is why it’s frequently used in backpacking water filters and other portable products. In larger-scale products, carbon is often combined with other elements to create a complete water filter system.

Two types of carbon filters are commonly used in commercial water filters: granular activated carbon (GAC) and carbon block. GAC is made up of loose granules that allow water to flow easily through the system. GAC is typically injected with heat or steam to “activate” the carbon, which opens up pores on its surface and increases its adsorption capabilities. A disadvantage of GAC is that channeling can occur when water flows through the system, where it bypasses the carbon particles and carries contaminants straight to the water supply.

Membrane Filtration

Membrane Filtration is an advanced water purification technology that uses thin barriers to selectively allow certain substances to pass through, while blocking others. It is commonly used in a wide range of industries to filter liquids and gases. It is a non-thermal process, meaning both feed and product streams remain in liquid water dispenser for business form. This allows for higher filtration efficiencies than other types of industrial filtration processes. It also has the advantage of being able to operate at very low temperatures, which prevents protein denaturation and other unwanted changes in product sensory qualities.

It is also a very sustainable solution, as it minimizes energy consumption and waste water production. It also helps meet strict drinking water standards, making it a safe and reliable choice for industrial or residential use.

The design of a membrane filtration system can be customized to fit the specific application using the appropriate membrane material, pore size, and configurations. The optimum performance of the system is determined by testing the permeability and flow rate at the desired plant operation. Once this information has been established, it is programmed into the membrane systems control logic.

The most important benefit of membrane filtration is its ability to separate a wide range of particle species by molecular size. This method is highly accurate and sensitive, especially when it comes to determining the presence of bacterial colonies in samples. It can even detect very low levels of microbes that are difficult to identify with other testing methods, such as Most Probable Number (MPN) and Pour Plate tests.

Backwashing Filters

Backwashing filters use a tank filled with one or more types of granular filtering media. Depending on the type of water treatment you need, the filtering media may be sand, anthracite, carbon, or other minerals. Untreated water enters the tank and passes through the filtering medium, which removes or changes contaminants in order to produce clean, safe drinking water. Backwashing removes dirt particles from the filtration medium and resettles the bed for another filtration cycle.

When the contaminant level is high enough that the filter medium is saturated, the control valve initiates a backwash. During backwashing, water moves rapidly backward through the filter at a rapid rate. This rapid upward flow washes away the collected contaminant, rinses the filter, and eliminates channels that form within the filtration medium.

Generally, the most popular backwashing filter is made with granular activated carbon. This is a very efficient contaminant removal medium that can also enhance taste and odor, as well as remove chlorine, organics, pesticides, and other volatile chemicals. US Water carries several different carbon systems including Centaur which is specifically designed to remove chloramines.

These backwashing filters can also be configured with calcite which is a sacrificial or consumable type of media that increases the pH of acidic water. This type of media must be refilled or replaced periodically. US Water also offers FloMag and Corosex, which are magnesium oxide medias that can be used in conjunction with calcite or on their own to raise the pH of hard water.
