About the Client
A meat packaging plant in Co Waterford Ireland
Industry: Meat packing, part of a group of 22 sites
The client is a major supplier to McDonalds and supermarkets in Ireland and the UK.
The Challenge
The client was pursuing the use of a borehole for the supply of make-up water to two large Evapco condensers. Site already had an existing water treatment supplier treating the condensers whom had recently submitted a large quotation for dosing/control equipment for a third new condenser to be installed.
The local Feedwater consultant was invited to attend a meeting with a view to providing consultancy regarding the new site borehole and to supply a price for the supply of the dosing/control equipment for the new condenser tower.
Feedwaters’ advice was sought to ensure that site were not being advised to purchase any equipment that was not required, to attain good value for money and also to ensure that the galvanized condenser coils on the new tower were passivated according to the manufacturers specification.
Feedwater was approached for their expertise after a referral by an adjacent site. Feedwater was one of two companies who submitted a technical specification/costs for the project.
Feedwater was very quickly able to prove that the competitor was trying to sell the site equipment that they did not need to buy and in the end Feedwaters’ equipment quotation was €13500 lower than that of the competitor and the specification for the treatment program and dosing/control equipment turned out to be higher as well.
The Solution
Due to work at the neighbouring site, the Feedwater consultant had gathered historical water analysis data over 2 years from the same borehole source and had established that it never varied in content, the results were identical to the client and the consultant was able to establish that the water did not need to be softened prior to being fed to the tower as they could attain 5 cycles of concentration minimum after taking into account Chlorides and Alkalinity without ever exceeding Evapcos’ maximum limits. The consultant contacted Evapco for their commissioning specification to be used in discussion meetings as proof of Feedwaters’ analytical data/recommendations.
NB; The existing supplier had insisted on softening from 70ppm to 0ppm total hardness and re blending back to 50ppm which was not needed. This would have been a waste of resources as hardness was not the factor limiting cycles of concentration it was chlorides.
Instead Feedwater proposed a Coolguard regime with only two chemicals, CG401 and single Bromine Biocide. The existing supplier had suggested that a secondary biocide was needed for compliance and that Bromine alone was not a compliant program. To refute this the consultant sent the client the relevant pages from the HPSC2009 ACOP/Guidelines for Legionella control as proof this was not a requirement. As a result Feedwaters’ solution only needed to supply one pump and a biofeeder instead of the incumbent who quoted two pumps and a biofeeder.
Several meetings were held with the site engineer, the group project engineer and eventually with the buyer where it was decided that the Feedwater proposal was much more appropriate for the application and solution to the problem.
Once Feedwater were awarded the equipment supply the client asked the consultant provide quote for the annual water treatment contract on the new tower.
The Results
Upon the implementation of the Feedwater Coolguard/Bromine treatment regime site testing showed an excellent level of passivation. System control also improved as Feedwater incorporated redox for superior control compared to the previous system which had only used timed dosage.
Immediate Benefits
- A saving of €14,000 over the initially quoted outlay.
- Peace of mind that the new galvanised condenser coils were passivated correctly.
Long Term Benefits
- Longevity of plant life due to superior protection & clean condenser tubes
- Condenser tubes remained clean and unfouled.
- Excellent Legionella compliance
The Conclusion
Winning the site business on price and technical merit Feedwater was able to prove that the existing supplier was not acting in the best interests of its clients, concentrating more on sales than recommending the most appropriate solution.
The customer saw significant savings and much improved system treatment using the Feedwater Coolguard treatment regime and as such the group project engineering team were eager to ensure Feedwater would be in the run to quote for the remaining 21 sites when the tender opens.
