What do you do when your water treatment plant is no longer fit for purpose?

It’s not uncommon for businesses to have water treatment plants on their premises that are out of sync with their outputs.

This is mainly due to the fact:

  • They’ve inherited their plant
  • Their manufacturing processes have evolved
  • They’ve not maintained or upgraded their system over the years

When it comes to the latter, the cost and hassle of sourcing a water treatment specialist and replacing their system with a newer model, are very often among the key barriers for businesses. And then, of course, there are some business owners who don’t realise that their water treatment is in need of an upgrade until they notice a drop in quality caused by untreated water.

Untreated water contains more contaminants than treated water

And it’s these contaminants that are responsible for causing no-end of issues – from compromising quality levels to generating increased downtime (caused by having to repair or replace tools and equipment or clean hard water deposits off them). System breakdowns aren’t uncommon either.

Repeated system breakdowns were one of the reasons that prompted one of our clients, a property manager for a private high end apartment building, to contact us.

When they came to us they were experiencing multiple issues, which mainly stemmed from the fact their water treatment plant was no longer fit for purpose.

When we inspected their system we discovered it:

  • Was too small to cope with their water flow rates – which meant they frequently ran out of water
  • Had been over engineered for their requirements – so wasn’t geared up to work to their advantage
  • Was costing them too much – they were spending excessive amounts on filling their plant with salt as they couldn’t seem to top it up
  • Was a real chore to use – they were softening the water, then putting it through a Reverse Osmosis (RO) and a series of filtration plant, and then re-mineralising it to make it suitable for drinking

After suffering multiple breakdowns, not to mention the on-going issues above, they contacted us to see if we could provide them with a cost effective and efficient solution tailored to their business needs.

Out with the old… and in with a new nano filtration system

Our team of engineers removed the existing plant and replaced it with an Excel Water EXNF800 8m3/hr nano filtration system.

How nano filtration works

Nano filtration is a membrane filtration-based method that uses nanometer sized through pores. Nano filtration membranes have pore sizes from 1 to 10 nanometers, smaller than that used in microfiltration and ultrafiltration, but just larger than that in reverse osmosis.

The membranes used are predominantly created from polymer thin films. Nano filtration works by removing the total dissolved solids that are present in water. The separation process stems from the naturally occurring phenomenon, known as osmosis, which provides good quality water that doesn’t contain any sodium.

During the process, two waters are separated by a semi-permeable membrane one – with a high concentration of dissolved solids and one with a low concentration. The semi-permeable membrane only allows good quality water to pass through, leaving the majority of the solids behind. When pressure is applied to the water that contains the high concentration of solids, the volume of water on the low concentration side of the membrane is increased and good quality water is produced.

Thanks to our expertise, our client’s operations are no longer being compromised on numerous levels by poor quality water issues that were caused by not having the right water treatment equipment in place.
