Water filters and their effectiveness in reducing water contamination

Water filters are the most efficient way of reducing water contamination and removing contamination in your water. Contaminated water contains sediments and disease-causing microorganisms such as bacteria, protozoa, and viruses. There are filters specialised for filtering certain water contaminants, and there are generalised ones that filter many contaminants. Modern filters come in various shapes and sizes and are capable of filtering chlorine, fluoride, heavy metals and other sediments. The following are some of the types of water filters and how they operate.

Reverse Osmosis (Osmotic Membrane Technology)

This is the most efficient filtration technology, and it’s capable of filtering nearly all the water contaminants including heavy metals, fluorine, chlorine, sediments, and excessive nutrients and minerals. The technology applied here is the use of semi- permeable membrane combined with a pressure of about 35- 40 psi. The membrane has tiny pores, which can only the tiny water molecules to pass through.  All other particles are left behind, washed and piped out to the main drain.

The semi-permeable membrane is usually fitted with other filters in a system known as Reverse Osmosis Water Filtration System. 5 stage reverse Osmosis System uses a total of 5 filters to ensure that the water is completely purified. The filters which are usually combined with this membrane include sediment pre-filter, carbon pre- filter and a carbon post- filter.  The pre-filters protect the osmotic membrane from damage while the post-filter is meant to polish the filtered water to ensure it is of high quality. This water can then be stored in filtered water coolers, office water coolers and let out in water cooler dispensers, faucets or drinking water fountains.

Activated Carbon Filters

Just as the name suggests, these water filters are made up of special carbon. The type of carbon used here is the one that has been activated to attract a large number of impurities present in water. Activated carbon filter can be found as a complete stand-alone filtration or in complex systems like the reverse osmosis system. Its design technique allows it to have large bonding sites for organic impurities.

These filters work by a process known as adsorption. This is the process through which the impurities found in water chemically bond with the activated carbon. After water enters the filter, these impurities typically attach themselves to the activated carbon. The level of filtration depends on some factors such as the speed of water flowing through the filter and the concentration of carbon.

Alkaline/Water Ionizers

The alkaline water ionizers water filtration technology works through a process called electrolysis, which raises the water PH. Usually, water is subjected over electrically charged plates that separate it into its acidic ad alkaline components. The negatively charged electrodes attract the positive ions hence leading to reduction. The positively charged electrodes attract the negatively charged ions hence resulting to water oxidisation. The reduced water is ideal for cooking and drinking while the oxidised water can be used for laundry, cleaning utensils, cleaning wounds and even for sterilisation.

UV Filters

UV filters make use of ultraviolet radiation to get rid of pathogens that may be present in your water. In this process, water is usually exposed to UV rays which are then absorbed by the microorganisms found in water. The UV rays alter the DNA of these microorganisms hence destroying them and leading to their death. This is the best way of eliminating waterborne diseases to provide safer drinking and cooking water.

Infrared Filters

Infrared water filters are commonly used for water softening. They depend on light and heat to give water a softer feel. Soft water is usually free from heavy metals and excess minerals and nutrients.


The type of water filter you choose depends on the level of water contamination. When purchasing a water filter, you should consult an aquafil expert since different water filters come with different filtration technologies.

Methods of Water Softening

Water is an important resource that is required by all living organisms for survival. We all depend on it for purposes such as laundry, washing and cooking & drinking. It is usually available in two forms; hard water and soft water.

What is Hard Water?

The simple definition of hard water is ‘water that contains a large amount of minerals in it’. The minerals predominantly found in hard water are calcium, magnesium carbonate and manganese. These minerals that make water hard tend to bring negative effects to the water. Hard water can stain bathtubs and utensils, prevent proper lathering, leave some scale deposits on the coffee maker as well as make laundry generally dingy. It can also affect the proper function of your electrical appliance that use water like electric kettles and give a pale appearance to you clothes, skin and even hair.

Hard water can come from different sources where minerals can easily dissolve into the water. It therefore usually has different levels of hardness, depending on where it comes from. The hardness of water is measured in GPG (grains per gallon) or PPM (parts per million of mineral). 17.1 PPM are usually the equivalent of 1 GPG.

Soft Water

Soft water is the opposite of hard water. It is basically water that has a minimal amount of the minerals that cause water hardness, magnesium and calcium. The major source of soft water is rain. Rain water is usually collected from roofs and then stored in tanks. It sometimes can also be obtained from specific drainage basins that are formed by hard impervious rocks that lack calcium. It can then be dispatched using water bubblers.

Soft water is also obtained from hard water. This is through a method called water softening. The water obtained through this process is then usually referred to as softened water. Though lacking significant magnesium and calcium ions, it may contain high levels of sodium and bicarbonate ions.

What is Water Softening?

As already stated, this is simply the process of removing magnesium and calcium ions from water. The process helps us to get rid of the problems brought about by hard water, especially at home. Softened water can then be stored in water cooler dispensers from aquafil  water coolers Sydney. Since there are different efficient methods used to carry out this process at home, I will take you through them.

Types of Water Softening Methods

Ion Exchange

Ion exchange is the oldest and most common method of water softening. Generally, it entails exchanging the magnesium and calcium ion contained in hard water for sodium ions. Since each calcium and magnesium ion has a positive charge of 2, each ion is exchanged for two sodium ions.

The sodium ions mostly come from a brine solution, with the displacement of sodium taking place due to the more powerful charge of magnesium and calcium. The exchange therefore frees water of free magnesium and calcium ions, making the water soft.


This is where water is heated inside a container till vaporisation starts. This vapour is then fed to a container with a cooling unit, through a tube. The vapour then condenses, changing back into its liquid state, water. This distillate is usually pure of all impurities, not only minerals.

Though cheap, it’s only used for the production soft water that is only needed in low quantities, especially for drinking and cooking purposes. It is also a method of water purification.

It however produces water that lacks even the essential minerals needed for the body, and therefore is not advisable for drinking every day. Alkaline filters can however be used to re-mineralize the water, before putting it in office water coolers.

Reverse Osmosis (Membrane Technology)

This is an effective method for both water purification and water softening. It uses a number of stages to produce highly purified water. Calcium and magnesium ions are eliminated at the reverse osmosis membrane chamber where a pressure of about 35 psi is applied. Only water molecules are able to pass and therefore the product is usually softened water. The unwanted water is usually piped out to the drainage and then the softened water can be directed to filtered water coolers.


Water softening is usually important at home, especially if you live in area where hard water is the readily available type of water. Softening the water provides you with numerous benefits and helps you avoid complications that would otherwise have been a result of excessive consumption of minerals.

Lead in your Water; Causes & Removal Techniques


There are different water contaminants such as heavy metals, lead, excessive minerals, and nutrients. The various water contaminants have various methods of finding their way into the water. In this article, we are going to look at lead as one common and dangerous water contaminant.

What is Lead?

Lead is a naturally occurring metal that exists almost in all parts of the world. It is classified in the group of carbons and contained in most of the equipment we interact with and use in our day to day activities and functions. It is a threat to both the health of children and even adults, though children are the most to its effects.  Children affected by lead suffer from constipation, fatigue, learning difficulties, slow growth rate, and development, vomiting, and loss of appetite among other health problems. For an adult, you may experience abdominal pains, memory loss, headache, muscle pains, reduced sperm count in males, joint pains, high blood pressure among other symptoms.

How do you know that your water is contaminated with lead?

Unlike chlorine, lead does not have a taste or smell, and neither can it be seen. The best way of determining the presence of lead in your water and the level of contamination is by testing your water. This is the only reliable way to enable you to protect yourself and your family members from consuming lead-contaminated water.

How does Lead get into the water?

Plumbing is the primary source of lead contamination in water. In most cases, the pipes used in transporting water are usually the cause of lead contamination. Older homes are likely to suffer from lead contamination in their drinking and cooking water. This is because some of the pipes used in transporting water in these homesteads were laid several years ago before the community realised the dangerous health effects of the substance.

How to remove lead from water

It is important to know the level of lead contamination in your water before deciding on the best method of lead removal. The following are some effective methods of removing lead contamination from water. They can be used alongside your office water coolers, water drinking fountains and home water cooler dispensers.

Using a Lead Water Filter

Lead water filter is the best way of protecting yourself and family members from lead ingestion. Filters can be installed in water cooler dispensers, office water coolers, drinking fountains and water bubblers. A water filter can be placed under the sink, on top of the counter, on water pitches or you can just attach it to the faucet.  Filters come in various types and forms including water filter coolers, water cooler filters, and others. Before purchasing any water filter, always ensure that it is NSF certified for Lead Removal.

Replacing Lead Water Pipes

Most of the plumbing lines, especially water pipes that were laid several years ago, have high levels of lead. Knowing the type of pipe that supplies your domestic water is imperative when it comes to protecting yourself from lead. You can determine the presence of lead in your water supply system by yourself using very simple methods. One of the best ways of detecting the presence of lead is by using a coin to scratch the pipe and then check the colour. Pipes made of copper have the colour of a penny while those made of lead have the colour of nickel. It is easier and cheaper to replace lead water pipes that have been used for private home plumbing. However, for public plumbing, it is relatively expensive and arduous, and you may resort to other methods like water filters.

Flushing out Water before usage in the morning

Though it is a wasteful practice, it may act as a short term solution to lead contamination. If you rely on public plumbing for your water supply, you may opt to flush water in the morning. Flushing out is meant to get rid of the water that has stayed in the lead pipe overnight hence increasing chances of lead leaching from the pipe into the water. This method may not be very effective, but it reduces the level of lead contamination in water.


Lead contamination poses great health dangers. It is, therefore, important to detect the presence of lead contamination in your water then reduce it, or remove it altogether.

How to Remove Chlorine from Water

Chlorine is a chemical commonly found in water. It’s most common in areas that are supplied with municipal water. Municipalities make use of chlorine for the treatment of water to kill microorganisms contained in the water. These are disease causing microorganisms like protozoa, bacteria, and viruses. It is usually effective in destroying these pathogens and making water safe for drinking and other family chores.

Chlorine, however, does have its side effects. Its long-term exposure can adversely affect people that suffer from asthma, skin irritability and other skin related disorders.

How harmful is chlorine in tap water?

Chlorine easily gets into the human body. This is through drinking chlorinated water or taking a shower using this water. It also gives a strong unpleasant odour and taste to water. This then affects the taste of certain foods and coffee, if used for cooking purposes. It also affects the skin, hair and general wellbeing of a person. It makes the skin irritable and makes your hair dry out. It can also bring bladder and intestinal complications, especially through the exposure of chlorine by-results, trihalomethanes (THMs) and halo acetic acids (HAAs).
Drinking water that contains this by-product increases the risk for liver, kidney and central nervous system complications, as well as cancer.
However, there are several methods to remove chlorine from water that you use for your family water have been devised. These are methods you can use, instead of having to buy single use plastic bottle water that is expensive in the long term, as well as environmentally unfriendly.


Chlorine is a gas. It therefore readily escapes from water, when left in the open. You should put the water in a container that has a large opening, then leave it in the open air to ‘breathe’.  Though a decent and inexpensive technique, this method requires a lot of time. The water should be left for around 24 hrs.


This method takes far much less time than off-gassing. It simply involves heating water in a container and letting the chlorine contained in the water escape. For efficiency, this should be done for around 15-20 minutes. However, this method can only ensure that you get a few litres of water, just for drinking.
After boiling, you can then put the water in a water cooler dispenser for drinking purposes.

Using De-Chlorination tablets

Another method of de-chlorinating water is by use of dechlorination tablets. It’s a simple technique that only needs you to add the tablets to chlorinated water. These tablets contain vitamin C (ascorbic acid) and usually react with the chlorine, forming a compound that will then free water from chlorine.


This is one of the most effective methods of water purification. Whether you are using water from a municipal source or a water bubbler, we all need an appropriate water filter for the removal of chlorine. There are many and different types of filters today that include whole house water filter, water cooler filters, faucet filters, etc. To filter chlorine, you have to choose properly since not all filters can.

The best chlorine filters are carbon filters. When chlorinated water is passed through the filter, the carbon absorbs chlorine contained in the water, freeing the water of the smell, odour and other negative effects of chlorine.

Reverse Osmosis

This is a variation of a filter, but far more advanced and effective than the general filters such that it can be termed as a method of its own. You can use it whether your water comes from the municipal supply or from a personal well through a drinking fountain. These systems use a 5 stage filtration system for production of highly purified water.

It is at the second of these stages where chlorine is gotten rid of. This is the carbon water filter stage. After water advances from this filter, all other elements larger than water molecules are filtered at the osmotic membrane chamber. There’s then another post-filter that contains carbon. This gets rid of any remaining chlorine that may still be in the water. The water produced by this system is of a very high quality and free of chlorine.


It’s highly advisable to get a water dechlorination method for your home, in order to keep your family safe from the dangers posed by long-term usage of chlorine. After de-chlorination, you can then use cool water dispensers or water coolers Sydney for your drinking water from aquafil.
