The Waterwise 4000 is one of the most effective distillers to filter the presence of contamination-causing organisms, like coliform, e. coli virus, and bacterial preservatives in tap water.

When UV disinfection sterilization kills coliforms and filters reduce them, distillers such as

Waterwise simply heat water to the boiling point, which causes it to evaporate, leaving coliforms to remain within the chamber.

There are many different distillation stages; however, you don’t have to know how to take advantage of this Waterwise 4000 feature. 

Add the municipal unfiltered water or well water into the rolling boil chamber, click “start,” and leave the system to do its work.

When unfiltered water evaporates in the chamber, it travels through a tube and into the drinking water supply collector. It condenses and forms municipal water droplets.

Most contamination-causing harmful pathogens found in wells and other unfiltered water sources cannot take on a gaseous form – including bacteria.

It means that the bacteria that cause the water supply with coliform remain at the surface water or chamber.

Waterwise 4000 can produce one gallon of steam distillate in only four hours. If you’ve researched distillers, you’ll see this is quite good.

What Are Coliform Bacteria?

Bacteria, also known as coliforms, are a common type of bacteria growth that typically live in the digestive tracts of human beings and warm-blooded animals.

They pass out in excrement and are found in plants, soil, and other organic matter.

If they are present in the drinking water supply or food items, this is typically a sign of unhealthy conditions.

In addition to being harmful to health risks, they can also signal the presence of dangerous pathogens that cause disease in the food or drink they’re present.

There are three forms of bacteria having three different measurements.

  • Fecal Coliform: These bacteria live in the intestines of warm-blooded animals and fecal matter.
  • E. Coli: Full name is Escherichia coli, present in the intestine and feces of humans and animals.   
  • Total Coliform: Numerous species are included in the total presence of Coliform Bacteria growth. They live in various environments such as groundwater, soil, and even warm-blooded animals‘ digestive tract.

Other microorganisms found in surface water are:

  • Viruses – Norwalk virus, Rotaviruses
  • Protozoans / Parasites – Giardia, Entamoeba, and Cryptosporidium
  • Bacteria – E. coli, Legionella, Enterococci, Shigella, Vibrio, Salmonella,
  • Enteroviruses – coxsackievirus, polioviruses, echoviruses, 

How Can Coliform Bacteria Get Into Water Sources?  

Coliform bacteria levels can be found on surface water sources like rivers, lakes, streams, ponds, and wells.

It can introduce into water conditioner sources after rains wash the animal’s excrement.

Animals and cattle can defecate directly into minor streams, which flow into more giant lakes and rivers.

If humans’ sewer treatment systems can’t cleanse the sewage. Before it can be appropriately discharged, in some cases, water with coliform may be released into natural rivers.

Bacteria may enter your well water supply in many ways. 

Rainwater can flush animal waste into the well if a proper cap is not below the surface level. 

Suppose a casing is damaged or the hole was constructed incorrectly. In that case, contaminated water could get into the well at a lower level.

When the casing is affected or damaged, the septic has a weeping bed that is not sufficiently close to the water. High coliform levels could be observed within the well water.

What Is The Method By Which Bacteria Are Identified?

What Is The Method By Which Coliform Bacteria Are Identified?  

  

Water testing for coliform is relatively easy to acquire within North America. One can obtain it for free or at a low operating cost in numerous countries.

After running the types of water filters in the home for a couple of minutes, take a small amount of bottled water and put it inside a container containing a preservative for bacterial contamination.

The water samples must be immediately transferred to the laboratory and put in a petri dish containing harmful bacterium food.

The dish is kept at a warm temperature to promote accelerated bacteria development.

A large bacteria colony will appear wherever only one microbe is present.

Results of city water testing for bacteria are usually presented in CFU/100ml.

It translates into “colony forming units per 100 milliliters.”

How Can I Filter the Coliform Bacteria Out of the Water I Drink?  

There are various methods to getting rid of bacteria from your water softener, such as coliform.

An ultraviolet System is the most straightforward, economical, and efficient solution for households to protect their water against harmful microorganisms.

A UV system is an aluminum cylinder that has a UV disinfection lamp

The alkaline water flow rate through the chamber made of steel, exposing bacteria to extreme levels of ultraviolet light. The radiation kills germs, making them inert.

What Are the Health Risks of Coliform Bacteria?

Consuming bacteria in beverages or food is like playing the roulette game. You can never know for sure whether the bacteria could cause harm.

A few common drinks of water with coliform discovered in bottled water that has been contaminated are not human-caused.

However, certain strains of E-coli (Escherichia coli), a sub-group within the Fecal coliform bacteria that live in animal fecal matter, may cause serious illnesses

The health hazards associated with E-coli are:

  • Fever  
  •  It can cause nausea.  
  •  Blood in urine  
  • Kidney failure
  • Urinary tract infection
  •  The kidney problems.  
  • Diarrhea and vomiting  
  •  Severe stomach cramps  
  •  Dehydration  

Suppose fecal coliform or E-coli is detected in your water.

In that case, It’s also a sign that other harmful pathogens are also present and can cause viral infections and human diseases such as:

  •  Types of viruses that can are responsible for polio and hepatitis  
  •  Protozoa cause dysentery.  
  • Bacteria that can cause typhoid fever as well as cholera  
  • Helminths such as tapeworms can lead to diarrhea and malnutrition.  

What Should Consider When Buying Best Filter for Bacteria?  

The search for a coliform filtration system isn’t as difficult as some think.

You need a basic understanding of filter bacteria in a water softener and precise information on the features to look out for.

Filtration Technology

Three water treatment methods are leading the way in the elimination of coliforms.

  1. Ultraviolet (UV) or purification with ozone

These methods kill bacteria but can’t remove the bacteria from water. 

That means there are still traces of bacteria in the water you drink. In addition, it needs lots of electricity.

  1. Ultrafiltration eliminates viruses and bacteria.

Ultrafiltration membrane technology is the most recent and best in water purification, removing viruses and bacteria. 

It disinfects and purifies the water to make it great tasting and safe to drink. 

Ultrafiltration eliminates over 99.9 percent of the contaminants and viruses.

The innovative technology allows you to flush your membrane when stuffed with pollutants.

Absolute charged nanofiber filters get rid of viruses and bacteria. 

They have a “charged” high zeta potential that draws ultrafine contaminants such as cysts and pathogenic bacteria smaller or larger. 

The elimination rate of pathogenic bacteria and viruses is higher than 99.99 percent, and over 99.95 percent of cysts.

  1. Reverse Osmosis 

It can remove bacteria; however, it’s not perfect. Reverse osmosis systems are seldom “certified” to remove bacteria. 

Verify that the manufacturer has documentation to confirm that the RO system’s fact certified to eliminate bacteria. 

Due to its size, a reverse osmosis filter can remove bacteria because it cannot traverse the reverse osmosis membrane.

Filter Type

When deciding on the innovative filtering technology, one must choose the device type.

Types of water filters are available in two broad categories: point of entry and point-of-use.

  1. Filter Pitchers

Does Brita filter effective in removing coliform bacterium? What is the situation with Zerowater filter coliform removal capability?

These are valid questions people have. 

Unfortunately, neither Zero nor Brita filter can kill or eliminate bacteria.

To ensure the elimination of coliform, they should have reverse osmosis membrane technology.

UV filters sterilization technology and ultrafiltration membrane.

With the dimensions of pitchers, these two options aren’t feasible. We don’t know of pitchers equipped with ultrafiltration membranes

They typically contain an activated carbon filter.

  1. Under-sink Filter

Under the kitchen sink, a water filter is a popular point-of-use smaller version of whole-house systems for filtration.

You can place a sediment filter under any sink water filter. However, specific models can double as a point-of-entry, whole-house filter.

  1. Countertop Filter

The name implies that the devices are placed on a counter or table. 

Some models require manual water refills, and others a water tank connected to a faucet for the sink filter. 

Make significant changes to their home or go through the installation.

  1. Whole-house Filters

These are systems for point of entry installed after the main water valve in their home, before the water line branches to smaller distribution lines. 

A house filter is perfect for households that require eliminating coliforms from every water faucet and water fixture.

Contaminant Removal or Water Purification Capabilities

It is recommended to verify the coliform-removing capabilities as much as you can purchase one water system.

It can kill or eliminate as nearly 100 percent of the types of coliform bacteria as possible.

For instance, filters with 99.99 percent water with coliform removal efficiency are more effective than those that only remove 90 percent.

Potential buyers might also consider examining other microorganisms and water pollutants the device can eliminate. 

It will be good if it also kills parasites, viruses, and protozoa.

Cost of Operation

Cost of Operation Water Filter For Coliform Bacteria

Ultraviolet purifiers for manual water refills require electricity to provide power to the UV lamp. Some UV filter units operate on 40 watts; however, most need 50 and 60 Watts.

It is essential to remember that this equipment may need to be operated continuously.

Thus, it is most important to calculate the additional costs of the electric bill before buying.

For traditional filters, one must think about the filter’s life span.

Membranes and filters are durable, usually lasting just an entire year in the case of filters and more than two years with other elements.

Regular maintenance can prolong the lifespan.

Coliform Removal or Complete Water Treatment System

It is also essential to decide whether to purchase a specific coliform-eliminating filter or a whole process for treating water.

Families with an established filtering system might decide to buy a UV sterilization technology device and place it in the pre sediment filter.

Select is a multi-stage filtration system if one is looking to remove all waterborne contaminants. They include microorganisms, particles, CTO, toxins, heavy metals, etc.

Choosing one with UV treatment technology and reverse osmosis elements is recommended.

Installation Ease  

Many people don’t like spending more money on professional installation. That is why purchasing a coliform treatment device that can be easily installed is essential.

Specific models come with instructions for installation, including everything needed to get the system running.

Some products are pre-assembled, making it easier to install the system.

However, it is essential to verify the compatibility of the hardware with the existing water fixtures. 

For instance, homes with water pipes of 1 inch should choose the types of water filters with the same sized ports. 

Although buyers can purchase an item of an alternative size, it usually requires adapters.

FAQ

Why isn’t every filter effective in removing the coliform bacteria in the water?

Coliform and E-Coli (Escherichia coli) bacteria are generally smaller than can be taken out using a typical house filter.

The coliform bacterium just passes through the medium with water particles, so more advanced filtering strategies are needed to accomplish the task.

Does boiling water eliminate coliforms?  

Yes, water boiling can get rid of the coliform. The water should come to a boil that is rolling for approximately 1 minute. 

That can be very effective in an emergency but not ideal if you intend to drink water regularly.

Can UV destroy bacteria?  

Yes, a UV bacteria water filter can eliminate contaminants, including coliform and E Coli, and provide safe drinking water. They don’t kill giardia and cryptosporidium.

Is reverse-osmosis able to eliminate coliforms?  

Reverse Osmosis is efficient in removing most microorganisms and coliform bacterium, including E. bacteria and Salmonella.

Can you shower in water containing the coliform?

Technically, it is safer to shower in water with coliform than to drink coliform-contaminated water. However, you must still treat your water whenever you can.

How can I ensure that filter products remove the bacteria in the water?

Check for lab reports on the internet. 

If you cannot locate them, ask the manufacturer to supply you with the report as an accurate report (and not just a copy-pasted report or a screenshot).

Final Thoughts

There are many possibilities if you’re trying to figure out the best water filter for the types of coliform bacteria in the drinking water supply.

You can utilize one of these systems not just for E Coli bacterium and other pathogens but also for heavy metals, arsenic, and many more contaminants.

That can be found in your well water or municipal water.

Nowadays, it is more crucial than ever to take the necessary steps to ensure that you drink healthful and clean water.
