Our client relies on a steam boiler 24/7 to operate their machinery, due to expansion additional machinery & processes were required which resulted in increasing water consumption.

A coarse filter was already installed, however, after carrying out water sampling our engineer noticed that the recycled water was not clean or safe and would cause serious issues with the steam boiler if not rectified.

We recommend installing an AFM® Filter (Activated Filter Media) as an alternative, safer solution which could fulfil the clients; new water demands.

The full unit offers a stable 1-micron filtration rate without flocculation, lower operating cost and less backwash water used.

The Filter was installed, commissioned and programmed and Our engineer noticed the difference in water quality immediately, within 8 months the site recorded 500,000L of water has been recycled safely within in the system.

Manufacturing Facility in Co. Cavan

OVERVIEW

Our clients rely on their steam boiler to ensure their facility is fully operational. After expanding their building and increasing the number of plant and equipment on site their water consumption increased.

To help with the increased water flow they decided to recycle the water from the condensate line to put back through the steam boiler. While this was a good plan the coarse filter installed was not sufficient for the job.

Our engineer was carrying out routine sampling in could visibly see that the recycled water was not clear, suspended soils were still in the water which was being put back into the system. If not rectified this could have damaged the system and caused massive issue at a later stage as the dirty water was already starting to clog the filters.

After speaking with our clients, we recommended that an AFM® Filter unit was set up as this a high performing filtering system with long lasting results.

• The filter media is made up of broken green/ brown glass which has mechanical filtration up to 1μm particles (95% removal)
• Absorption of organic substances including Hydrocarbon and Microplastic
• Increased surface area for superior filtration, the large surface area provides for superior mechanical filtration

The filter unit size was agreed and installed. We then commissioned and programmed the unit to ensure maximum efficiency.

Positive results were immediately noted, suspended solids is a minimum of >95% removal.

Within 8 months 500,000 Litres of water has safely been recycled back into their system.

Saving water, time and money.

WHAT WAS DONE?

After it was realized the water being recycled was not fit for purpose our clients and ourselves sat down to discuss other options to help the systems cope with the increased water consumption while trying to recycle as much as possible to help the environment and save on time, labour and costs.

We recommended an AFM® Filter unit was installed so that the water in the condensate line could be thoroughly filtered and put back through the system.

• 3 different quotes were sent, all for different sizes of units. Once agreed on size and price the system was ordered.
• Within a month the unit was installed, without any disruption and no downtime
• The unit was commissioned and programmed accordingly

We started to notice the difference in water quality immediately. Visually the water clearer and passing through the filtering system with ease.

Full training was provided to maintenance staff.

CONSIDERATIONS

• The steam boiler is an integral piece of equipment in the facility and so we had to ensure it remained operational at all times
• All maintenance staff has to be fully trained on the new unit and how the process works
• There are further plans for expansion so consideration had to be taken for this

RESULTS

We were delighted to be able to provide our clients with a relatively simple solution to their problem. Within a month of confirming what filter was required, our clients were able to recycle water in a safe manner meaning their steam boilers’ lifespan will be elongated.

We were able to help our clients recycle over 500,000 Litres of water within 8 months, this water would have been going down the drain and wasted otherwise.

CONCLUSION

It is important, especially in this climate, that everything that can be done to recycle water is done but this must be done safely. By installing the AFM® Filter Unit our clients were able to recycle a substantial amount of water safely so that an increased water consumption can be accommodated.

It is particularly important that steam boilers use the best quality water due to their importance. You should always speak your water treatment consultants when you are looking to make changes to your water systems or if you are trying to improve its’ efficiency.
