Frequently Asked Questions About Commerical Water Treatment

Why are my boilers scaling up?

Hardness salts are the cause of scale inside a boiler; if they are not prevented or removed regularly they will cause overheating.  This can lead to tube failure (explosion risk) and/or a reduction in the heat transfer properties of the transfer surfaces.  This in turn leads to reduced efficiency and increased energy costs.

Hardness salts must be removed before they enter the boiler system, using a Water Softener.

Should I be running Soft Water to my ice machine?

Without Soft feedwater, you will most definitely experience scale formation in your ice machine. Most of the time, we think of scale in relation to things that are heated. But in a commercial ice machine, scale forms as the water freezes on an evaporator plate. Since pure water freezes first, it leaves behind any dissolved minerals. When those minerals reach saturation, they precipitate on any surface that comes into contact with the water. Often, the scale forms on the walls of the water sump or on the distributor over the ice machine evaporator plate. When scale forms on the distributor, it causes an uneven water flow over the plate and creates “white ice”. This can lead to “freeze-ups” of the ice machine. The results are poor-quality ice and loss of ice production. In the end, the ice machine will require de-liming with an acid cleaner. Multiple cleanings with acid will eventually destroy the plating on the evaporator, resulting in ice sticking to the evaporator during the ice-making process. And, since most evaporator plates are made from plated copper, repeated acid cleanings will corrode away the copper, and the establishment must buy a new ice maker.

Are there water treatment alternatives?

Yes. In some applications, a Parafos Water Treatment System can replace the need for, and the use of, a Water Softening System. With a Parafos Water Treatment System, capital and installation costs are only a small fraction of that of Water Softeners. Operation and maintenance costs are also greatly reduced. Water use for backwash and regeneration is eliminated. Salt costs and labor intensive handling are eliminated. A Parafos Water Treatment System provides excellent protection from scale build up and also provides additional protection from corrosion. Replacing Water Softeners with Parafos Water Treatment Systems saves water and may qualify you for rebates from your local municipal government. What’s more, a Parafos Water Treatment System is an eco-friendly product!

What are the differences between multiple tank (Duplex, Triplex, etc.) Systems versus a single tank (Simplex) Water Softener?

Simplex Water Softeners are best suited to consistent demand applications of moderate total water consumption. The regeneration process is controlled by the multiport valve head assembly located at the top of a single vessel which is connected to a separate brine tank. Timer clock controlled or meter controlled Water Softeners can either be set for an immediate or delayed regeneration, preferably when water demand is low. During the regeneration process, the single vessel control valve will bypass hard water to service unless a bypass lockout facility is specified. The correct sizing of Simplex Water Softeners is crucial as the system will need to give at least one days softened water output before regeneration.

In comparison, Duplex Water Softeners give a 24 hour supply of Softened Water. Duplex systems use two resin vessels, one in service, the second on standby. The water flow to service is metered and when the service column is exhausted, the control valve automatically switches, allowing the second unit to go online. The exhausted resin in the first column is fully regenerated and remains on standby until the second column is exhausted, then the control valve switches back to the first column again. Parallel systems with both vessels on line at the same time are also available. A Duplex Water Softener is better suited for applications where a 24 hour constant supply of softened water is required or where times of water flow are varied. Using two smaller resin vessels as opposed to a large single Simplex system can reduce the height of your softening system dramatically.

Do you offer Backflow installations and testing?

Yes. Canadian Water Conditioning Inc. offers both installation and testing services for all Backflow Prevention Devices. As per municipality Bylaws, all commercial buildings must have, at the very least, a Premise Backflow Prevention Device installed after the water meter. As recognized by all surrounding municipalities, Canadian Water Conditioning Inc. is a trusted partner in this specialized division. Contact us today to schedule your appointment.
