Water filtration is the process of making water pass through a physical barrier to capture or reduce impurities. This is a simple explanation which could be a very complicated process depending on the type of filter used. There are many types of filters that include cartridge, bag, screen, multi-media, ultrafiltration, nanofiltration, and biological filters for example. At Intec America, we offer one of the broadest selections of water filtration systems for whole house and commercial businesses. These water filtration systems are sourced from industry-leading brands and have proven to offer the best benefits to users.

Types of Water Filtration Systems Provided by Intec-America

The following are a few popular water filtration systems provided by us.

  • Air/Ozone Injection Filters: Air injection filters are used to treat water having manganese, sulfur (hydrogen sulfide), and iron in it. In these filters, the air is directly injected into water creating a gas pocket at the top of the tank. The air acts as an oxidizer and the water free falls in an aeration process which assists in precipitating the contaminants.  The media collects sedimentary manganese, sulfur, and iron and purges these contaminants during the self-cleaning cycle.  The sediment-free water is delivered to the riser tube and is purified at this point. The demand for ozone water filtration systems is on the rise as it is a much stronger oxidizer. Enhanced Ozone Generator (EOG) is self-contained and is used to filter water with higher levels of iron, hydrogen sulfide, and manganese while using a similar concept that is mentioned above.
  • Ozonation: This refers to the ozone gas injection into water. Ozonation in water treatment is a process where ozone gas is injected into the water to filter iron and other impurities. This technology is also found effective in addressing biological concerns. The is a separate add-on technology with greater flexibility for concentration levels and flow rates.
  • Cartridge Filters: Cartridge filters are commonly used to remove suspended matter. The filter consists of a housing with a cartridge insert. They are commonly used with a water softener or reverse osmosis systems to remove sand and sediment that could hurt further processes downstream. Cartridge filters are generally small and designed for flow rates of 5-20 GPM. The particulate filters normally range in pore sizes from 200 down to 1 micron. They are distinguished as pleated, string, or depth cartridges. The pleated cartridges usually handle higher flow rates and can be rinsed and reused. However, string and depth cartridges can usually remove smaller particulates at a lower flow rate and cannot be reused. Carbon block filters can also fit in these housings and can remove a wide range of chemicals such as chlorine and pesticides. Fillable canisters can also fit inside these same housings and can hold specialized media and resins for tannins, nitrates, arsenic, and lead for example. The 10ʺ or 20ʺ systems are truly too small to be effective for whole house applications unless they are being utilized as particulate filters to protect equipment downstream.
Whole house cartridge filters essentially function the same as the filters mentioned previously. The larger size allows for higher flow rates as the surface area is increased dramatically. Also, with the larger surface area, smaller pore sizes can be used with less frequent maintenance or replacement. More specialized options are available with these filters as the housings are much larger. Applications include high-flow carbon block filters, microfiltration, Lead removal, PFOA (C8) and PFOS removal.
  • Bag Filters: Bag filters are generally used for commercial applications. These are intended for much higher flow rates than the systems above. The most common use is for the removal of suspended matter. However, some of these filters are highly effective at the removal of petroleum at residential flow rates and are more cost effective than the cartridge filters that would address the same issue.
  • Screen Filters: Screen filters can vary greatly in their size and volumes of water it can treat. These are best utilized for the removal of sand and large sediment. The advantage is that one does not need to throw away disposable cartridge filters, which can cost money over time. Some screen filters work by water flowing through a screen and gravity dropping particulates to the bottom for a manual purge or automated flush. However, others operate by centripetal force and use a continuous flow of water to purge the sediment.
  • Disc Filters: Disc filters are highly effective and are automated to flush when there is an increase in pressure. These are mostly used in commercial and industrial applications. Amiad is an industry leader and their SK2 unit under the Arkal name can be used for a large residence or irrigation for the effective removal of sediment with near zero maintenance.
  • Microfilters, Ultrafilters, and Nanofilters: Microfilters, ultrafilters, and nanofilters are very specific in their application. Watts Water Technologies developed the HydroSafe biological filter all-in-one filter that can remove chemicals and filter out many common microorganisms. This multibarrier approach also uses an internal UV light to kill any remaining bacteria or viruses that could pass through the filter. Enpress offers the PolyUF which can physically remove the smallest waterborne pathogen and reduce tannins without the use of chemicals that can affect the taste of the water. Nanofilters are mainly used in industrial applications to pretreat water going into a reverse osmosis system.
  • Backwashing Filters: Backwashable filters (self-cleaning) offer the widest range of water treatment options and these systems can be customized. They can use a single type of media or a blend of two or more media that can address a wide range of problems such as sediment, chlorine/chemical, iron, manganese, and hydrogen sulfide removal. The valve heads can be customized to allow for the injection of air or ozone to assist in oxidizing metals and gasses. Accessories, such a flow meters, pressure gauges, test points, and microswitches can be added to aid in quality control, remote access, and activating/deactivating other components downstream.

In some instances, aggressive pretreatment may be required before filtration. For example, well water with iron bacteria or high levels of iron may require a chemical oxidant injection with a holding tank of sufficient contact time to aid in the killing of bacteria and oxidizing metals. Ozone is more effective for high organic and inorganic loads as the contact time and maintenance is greatly reduced. If the pH is low, increasing the pH with a neutralizer may be necessary to effectively remove metals present in the water.

There are several types of filtration systems in the market and these are the more common. Intec has relationships with many OEMs and distributors and not all the technologies are discussed appear on this site.

Air / Ozone Injection

Air injection and ozone injection are not new to the industry. However, having the injection take place in the valve head to create and gas pocket for advanced oxidation is. It is highly effective and a more reliable injection process without the cost of additional retention tanks or pumps. Air injection is great for the treatment of elevated iron and manganese as well as moderate hydrogen sulfide. EOG (Enhanced Ozone Generator) is effective on high iron, manganese, and elevated hydrogen sulfide levels.

Ozonation

Over the years, ozonation has emerged as one of the most effective water treatment technologies for rapid oxidation and disinfection. Widely used for bottled drinking water, ozonation is performed by injecting ozone gas, which can be introduced at various points of the treatment depending on what one is trying to accomplish. At Intec-America, we provide ozone water treatment systems from industry-leading brands. Being at the forefront of water treatment technology for several decades, we perfectly understand the requirements and needs of our clients. What is Ozone? Ozone is an inorganic molecule of oxygen that features three atoms of oxygen instead of two. This is why it is depicted by the chemical formula O3. Ozone is formed as a pale blue gas in the environment and it is distinguished by its pungent odor. Ozone is naturally formed in the atmosphere during the lightning and thunderstorm. The air receives its fresh smell after lightening. Ozone is one of the most powerful oxidizing agents found on the earth. It is considered to be 51 times stronger than chlorine, and is also perceived as an alternative to chlorine water treatment in many cases. What is Ozonated Water? Ozonated water is the water that is treated using ozone gas. The ozone gas is introduced through Ozonator and the gas dissolves in water until a reasonable concentration remains. This unstable molecule quickly reverts back to its natural state of O2 and is why ozonated water can be used for drinking. How is Ozonation Performed? Ozonation involves ozone gas, which is produced commercially onsite using an ozone generator. Ozone gas has a short lifespan and cannot be transported or stored for a long time. Typically, ozone gas can be produced from the ambient air. This equipment uses the air (or at times compressed oxygen) present in the...

Backwashable Filters

What Are Backwashing Filters? Whole house backwashing filters are the most common point-of-entry (POE) systems sold today. They are popular because they can be customized for various application just be manipulating the media(s) that are contained inside the vessel or tank. Backwash filter systems are tank-style filters that are capable of self-cleaning by reversing the water flow internally (backwashing) to remove captured contaminants. An electronic control valve controls this flow of water and are programable to backwash on certain days, pressure changes, or volume of water that has passed through the system. They can also utilize a downward flow or upward flow set-up depending on the media utilized.   Generally, one or more types of granular filtration media(s) such as sand, anthracite, carbon, or other minerals are utilized inside the filter tank. Thus, they are sometimes referred to as a mineral tank.  The huge advantage of backwashing filters over traditional cartridge or bag filters is the latter two require manual cleaning or replacement.  Manual cleaning can be an inconvenience especially in cold or bad weather conditions.  A backwashing filter is more of a hands off approach that requires very little maintenance over the course of several years.   Backwashing filters are better designed for applications where pressure drop due to effluent turbidity is expected and cannot be tolerated. Backwashing water treatment systems trigger the reverse flow after specific time laps or pressure changes in order to avoid filter clogging. These filters are suited for the removal of different types of impurities; however, the filtration media differ according to applications.   There are different types of filtration medias that are used for backwash water filters applications. Some popular filtration medias used in backwashing water filters are Pyrolox, Birm, Calcite, Manganese Greensand, and Micro Z.   Let us go through the types...
