Chlorine in Water Filtration: Why it’s Used and What it Does

July 29, 2013

When it comes to potable water, chlorine has been used in the filtration process for many years. It is a method that is effective in preventing the spread of disease, and has been written about as far back as 1894. The first official use of chlorine water filtration/disinfection on a continuous basis in the U.S. occurred in 1908, and soon became widespread throughout the country.

Chlorine is added to water mains and storage tanks, as well as to the piping, at the end of the filtration process. Its presence kills pathogens that include bacteria, viruses, and protozoans. Uses in certain areas have all but eliminated typhoid fever, dysentery, cholera, and other dangerous diseases from the population, thereby lengthening community lifespans.

As one of the cheapest methods of water disinfection, chorine for purification and filtration is one of the most common. However, there are alternative methods, with varying degrees of success and cost effectiveness. These include ozonation (especially popular in Europe), use of chloramines, UV radiation, and, of course, home filtration.

Residential products such as Brita and PUR filters have gained in popularity in recent years, and are actually used to remove chlorine and its perceived taste by filtering it out. Much of their use is about personal taste and preference.

In general, whatever method is used, the most important thing is that filtration of the highest quality is performed at the very beginning, long before it reaches your faucet.


We’re First – And We’re At The Forefront of Municipal Water Filtration

July 15, 2013

When looking at the municipal water filtration process, where do you start? That would be with the filter media, like we provide here. Getting down to the core basics, and speaking in very general terms, the municipal water filtration process involves several levels and steps:

  • First, dirt and particulates are removed from the water.
  • Next, unwanted chemicals are removed.
  • Additives are added to the water.
  • Then, finally, residential tap filters remove the chlorine.

Not many people talk about what the water looks like at the very beginning of the filtration process… It’s definitely not pretty! The water is usually brown and full of dirt. That’s where the filter media steps in—it takes the particulate out of the water being filtered or treated at the start of the process, right after the municipality has pulled the water from some source – a river, a lake, an underground aquifer, etc.

Then multimedia filters are used at the different levels of the filtration process. Our media, including gravel, sand and anthracite, removes dirt and other particulates from the incoming water. Then the water goes down line to undergo additional processes where chemicals and other undesirable substances are removed.

Cities and municipalities add chlorine to the water to keep it clean as it runs through the piping systems to homes and buildings. By adding residential filters to water taps, the chlorine can be removed from the water to make it “fully clean” for the end customers. It’s as good as bottled water at this point, so drink up!

While this blog post offers a general and basic overview of the municipal water filtration process, you can get more detailed descriptions of the levels of the process and the types of filter media used by reading our previous blog posts. We’re happy to talk about the different water filtration media available today and the logistics of putting filter media to work in cities around the world.

Did we See You in Denver at AWWA’s Annual Conference and Exposition 2013?

June 17, 2013

We were at the American Water Works Association’s (AWWA) Annual Conference and Exposition (ACE) in Denver this year, and we hope you were there too! The event took place June 9th through June 12th at the Colorado Convention Center. The ACE trade show is the largest municipal show in the U.S., and it’s a must-attend event for anyone working in the water filtration and treatment industries. Why? The association sets all of the necessary specifications cities need to meet when purifying the city water.

On the ACE website, the AWWA president says, “If you attend just one professional development opportunity this year, I urge you to make ACE13 that event. At a time when efficiency matters, ACE13 offers a one-stop opportunity to get the targeted training you need, experience all the technology available to help you do your work, and consult with peers from throughout the world.”

cei carbon boothAWWA is the oldest and largest nonprofit, scientific, and educational association dedicated to safe and sustainable water in the world. The organization was established in 1881 and today boasts more than 50,000 members worldwide. The AWWA website states, “AWWA advances public health, safety and welfare by uniting the efforts of the entire water community.”

As an exhibitor at the conference, we were joined by nearly 10,000 other dedicated water professionals working together to define the future of the water industry, and we showcased all of the water filtration media we offer at CEI. We hope to see you again soon!

Here’s to our Company’s 15 Years!

June 4, 2013

Happy 15th anniversary to us! Can you believe it? This past April, we celebrated our fifteenth year in business, and we hope to have another successful fifteen years in our future!

As a company that started with one 5,000 square foot facility and two workers to a larger-scale company with a 21,000 square foot facility in addition to a separate anthracite plant, we can certainly say that we have grown since the beginning. While we began offering limited filter medias for the water filtration world, we can now proudly say that we now are a one-stop shop for all filter media needs, in addition to offering all other services our customers may need handled, including logistics and transportation. What do we have planned for future expansion? Specifically, we are aiming to supplement our current services with the addition of testing and consulting services. Although we have always helped customers in these fields, we have decided to formally offer them across the board, allowing us to be a helping hand for all of our clients. Not only that, but we continue to review new medias and ways in which to raise the quality of our filter media even higher as well.

In the next fifteen years, we want to become a bigger and better company. We pride ourselves on providing a personal touch and high customer service for all of our clients, and we plan on expanding that as we continue to move forward. Cheers to the next fifteen!

Let’s Filter through the Water Filtration Technologies

May 20, 2013

When you hear of water filtration, what jumps to mind first? Is it large municipal pumps cleaning water equipped for an entire town? Or does an image of your personal Brita filter pop to mind? When it comes to water filtration and filter media, both images are correct –there is a plethora of filtration options out there, from the government level down to the residential level. As water filtration experts, we deal with clean water on all levels.

Recently, we attended the WQA AquaTech trade show in Indianapolis, which focuses mostly on drinking water. Although we tend to cater to larger scale projects, our filter media has always been approved for the residential filters as well.

What types of filters are we referring to? Any filter that can be used in a home setting, meaning anything from Brita filters to sink filters. As we exhibited at the show, our entire range of filter media is applicable for residential water cleaning settings. We hadn’t attended the show in the past few years, and we were excited at the chance to show off our products, as well as demonstrate how they can be used in smaller drinking water filters. Essentially, the media is placed in the filter, and then the filter is attached to the water line, allowing for pure, clean water to come through. WQA AquaTech proved to be a rewarding experience, and we are pleased to be a part of the residential water filtration family!

Activate Clean Water with Activated Carbon!

April 23, 2013

Are you looking for a filter media that can be used in water and air filtration systems for the removal of both organic and inorganic contaminants? Does this particular media need to be used in either residential, municipal, industrial, and hazardous waste areas? If so, no need to look any further – activated carbon is a perfect choice for these applications.

How does activated carbon work? The media is able to physically and chemically absorb a number of contaminants from an affected water or air stream. What makes activated carbon so effective? Particularly, the chemical composition and molecular structure play a part, but it also depends on what type of carbon is used. Since activated carbon can be made from coal, coconut, shell, wood, bone, and pear, the size of the pores and surface area differs, affecting the rate of absorption. It depends directly, then, on the specifics of the application when determining which carbon to utilize.

Here at CEI Carbon, we offer a variety of grades and sizes in activated carbon. Specifically, our grades of activated carbon feature high durability, limited back washing, low fines, zero floating materials, and low pH levels. As with our expansive line of filter media, our activated carbon is NSF approved and exceeds AWWA standards. Whether you need a specific type and size, or want specialized logistics and transportation services, we can provide you with the most appropriate activated carbon for your filter needs.

You Can Find Greensand at CEI!

February 4, 2013

CEI Filtration is the place to go when you’re looking for Manganese Greensand™. We are the largest distributor of Greensand™ and have been distributing it since 1998. Even with the manufacturing of Greensand™ ceasing production, we will still continue to carry the product in stock until our inventory is gone, making us one of the few distributors of the product.

What is Manganese Greensand™?

Manganese Greensand™ is a granular filter media that removes iron, manganese and hydrogen sulfide when used in a pressure-type filtration system. Direct contact with the grains causes oxidization which removes soluble iron and manganese. After a service cycle, the unit is backwashed then regenerated with a potassium permanganate solution which restores its oxidative capacity. Manganese Greensand™ also directly oxidizes hydrogen sulfide and catalyzes the oxidation reaction.

What is GreensandPlus™?

Like Manganese Greensand™, GreensandPlus™ is a filter media that removes soluble iron, manganese and hydrogen sulfide, but it can also remove arsenic and radium from well water supplies. GreensandPlus™ has a silica sand core with manganese dioxide coating fused to it, which makes it the better option when dealing with high operating temperatures and high differential pressures.

If you’re interested in learning more about Manganese Greensand™ and GreensandPlus™, visit our website and if you are looking for Greensand™, we are your supplier!
