Water softener and more!

We have a wide selection of water treatment systems for all your water problems. Each system is tailor-made to precisely meet your needs.


Water softener

A water softener is primarily used to remove hardness (limestone) from your water as well as other minerals such as iron and manganese. When water is too hard, it can cause early deterioration of your home’s faucets and plumbing. Hard water can also cause problems like stains in the shower, toilet and more.

Do you have these problems? A water softener is a wise choice! A water softener is installed at the water inlet of your home. Your water passes through a resin-filled cylinder before being distributed throughout your home. At Purco, we custom build your water softener system and choose the resin best suited to your water.

The softener has an average life span of 12 to 20 years depending on the condition of the water and its use. The water softener requires the purchase of bags of salt in order to function. The amount of salt consumption depends on the water conditions and usage.


A conditioner could be the right choice for you! A conditioner is very similar to a water softener and works in the same way. Its clear advantage is that the conditioner can use specific resin combinations to treat a wider spectrum of water problems than the softener. A conditioner can also treat hardness, iron, manganese and tannin.


But what is resin?

Resin is formed from millions of tiny beads. As the water passes through the resin in the softener, the beads, which work with an ionic charge, will attract and store hardness, iron and manganese from your water, leaving only clean, softened water for your home.

Then the salt does its work. Salt is actually the soap of the resin. During the softener’s cleaning process (regeneration), the salt water is used to dislodge the impurities accumulated in the resin and send them to the drain. Note that the salt water does not go into the house, but only into the drain during its regeneration period. Your water will not taste of salt.

However, the water must not contain any sand or solid matter. But we have solutions for this problem too.



The activated carbon filter is used to remove chlorine, chemicals and bad tastes. The carbon filter is installed under the kitchen sink or elsewhere, as needed. It should be replaced annually or as needed.

The strainer is used to remove sand. The strainer is installed at the water inlet of the house. This filter is cleaned manually.

The sediment filter is used to capture sediment of various sizes ranging from 0.5 microns to 50 microns. The smaller the micron, the more small sediments are captured.


Ultraviolet lamp

Your bacteriological analysis turned out not to be non-compliant? An ultraviolet lamp will be able to eliminate bacteria such as E. coli, enterococci, etc. from your water. A UV lamp is a non-invasive ultraviolet disinfection system that does not use chemicals and completely eliminates bacteria. This method is gaining popularity for its effectiveness and easy maintenance, and does not alter the taste of water.

How does a UV lamp work? Water enters the stainless steel reactor and circulates around a glass tube called the quartz. The UV lamp is inside the quartz and is not in direct contact with the water. The UV rays pass through the quartz to eliminate harmful bacteria. For this reason, it is mandatory to do a physico-chemical analysis to check if there are any minerals that could dirty the quartz and prevent the UV rays from reaching the water. Quartz contaminated with iron, manganese, sulfur, hardness or tannin can affect the efficiency of the UV lamp or even render the UV system useless.

The UV lamp has a one-year span of radiation efficiency. Therefore, you should plan to change the UV lamp annually.


Reverse Osmosis

Reverse osmosis is used to remove up to 99% of the elements in water to produce very pure, tasteless water for drinking. Reverse osmosis uses no chemicals, only pre-filters, a semi-permeable membrane called reverse osmosis and a post-filter.

How does the semi-permeable membrane work? The water passes through the pre-filters and most of the minerals are caught. The water then reaches the osmosis membrane. Driven by your house pressure, the water enters on one side of the semi-permeable membrane and is forced through it. The holes in the reverse osmosis membrane, being smaller than the water molecule, force the molecule to squeeze through. In this way, all the other molecules (iron, hardness, etc.) attached to the water molecule are detached and remain on the other side of the membrane to be sent to the drain, leaving behind nothing but very pure water. The water then passes through the post-filter to remove the last small impurities that may have made it through.

Reverse osmosis can have several pre-filters, at least one sediment filter and one activated carbon filter (replaced annually). The reverse osmosis membrane should be replaced every 1 to 5 years depending on usage. The reverse osmosis water treatment system is installed under the kitchen sink with its own pure water faucet installed on the sink.

pH neutralizer

A pH neutralizer is used to increase the pH level of the water and to neutralize its acidity. A pH neutralizer is different from a water softener because it does not contain resin. It contains a sacrificial neutralizing agent, which means that it will be consumed with your water usage. It will need to be replenished depending on your water conditions and usage. This system is often required before using another water treatment device. In the case of acidic water, it would be a good idea to replace the sacrificial anode in the hot water tank with an impressed current anode.

Catalytic carbon

Do you smell an unpleasant odour when you turn on the faucet? Is your toilet stained with rust? Catalytic carbon can solve your problems.

Catalytic carbon has a great absorption capacity thanks to the porous surface on each of its small grains of carbon. This water treatment system does not need salt to wash, only water. Catalytic carbon is mainly used to remove hydrogen sulphide (sulfur, H2S), which can be recognized by its rotten egg or petroleum product smell. Catalytic carbon is also used to oxidize and capture iron and manganese through an air injection option. Lastly, catalytic carbon can remove chlorine and other chemicals as well as any undesirable taste.

The catalytic carbon inside the water treatment system should be replaced when its absorption capacity has reached saturation depending on the water usage and condition. Its average life span is 7 to 10 years.

Activated carbon

Does your water smell and taste like chlorine? The high porosity of the carbon grains in activated carbon means that its absorption capacity is very high. Water is enough to wash this water treatment system, no salt is needed. Activated carbon is often used in city water to remove chlorine and other undesirable tastes. It captures a large amount of chemicals. The activated carbon inside the water treatment system must be replaced when it has reached saturation.


An ozonator is used to oxidize iron, manganese and sulfur, to kill bacteria and organic matter, and to eliminate bad tastes. An ozonator works with a contact tank and a filter, depending on the application. An ozonator does not produce harmful by-products. Ozone is 1.5 times stronger than chlorine.


A booster is used to increase the rate or level of reaction of certain forms of oxidation. A booster eliminates or reduces the need for a contact tank.

Dosing pump

The dosing pump is used to inject chlorine at the water inlet to sterilize the water and/or oxidize iron, manganese or sulfur, or eliminate bad tastes. The dosing pump is part of a set of equipment that includes a contact tank, an activated carbon filter (to be replaced annually) and other equipment as needed or used.
