In part two of our interview with Marwan Nesicolaci, Sr., we find out more about the CAPITAL CONTROLS ® Ozone Generators.
Q: How do the water challenges and conditions differ in Singapore and in other SE Asian/ Asian countries?
MN: Singapore’s challenges will be to continue to be at the forefront of implementing new technologies. They have done tremendously well over the past few years and they have become an example to many municipalities around the world, in terms of adapting new technologies.
The challenges really are whether they continue to encourage the development and implementation of new technologies in a sustainable way.
We are one of the very first ones in Asia to implement brine electro-chlorination as an alternative method for disinfection for potable water. And we are very pleased to be there from the beginning when we piloted the technology for PUB when they were looking at various alternative disinfection technologies and because of its success, we sold a number of different brine electro-chlorination systems.
The adoption of newer and alternative technologies to meet their water needs is really something Singapore need to sustain moving forward and that is something that in the past differentiated them from the rest of Asia.
Q: What are the newly improved technologies and features found in the CAPITAL CONTROLS® Ozone Generators?
MN: The biggest improvement is really to use more updated electronics and console that can be remotely monitored. The digitalisation of components is an ongoing task which everyone is tackling now.
The other thing is localisation and regionalisation of the products. In China, ozone has a very important place in their water treatment industry. We are managing our infrastructure there by including local cross-engineers and local cross-institutions expertise to not only bring products into the market, but to deliver them together with the support team that is within the country.
What we do very well is transferring the knowledge and technology from our centres of excellence to the regional areas. To be able to support the product at local and regional level is very important, and in any market, providing support is critical to sustain the growth of the market in that country. We have been developing and strengthening our after-sales capabilities globally for at least seven years.
Years ago, we were more in a reactive mode in terms of after sales, so we were basically reacting to what the market needed. But we realised that our customers needed continuous support to be able to get the full life expectancy and value out of the products and the only way to meet this requirement was to be a lot more proactive in working with them. It is not only about making good business sense, but also to ensure that the customers are satisfied with their purchases over the whole life of the asset they purchased.
Q: What is the cost difference: Ozone versus Chlorine Gas?
MN: Ozone is a little expensive on the capital expenditure (capex) side, but it is not very expensive on the operational expenditure (opex) side, because you produce ozone from air or oxygen, so you don’t have chemicals to add. Other disinfection technologies have lower capex but higher opex.
That is why some end users look at the whole life cost instead when they analyse the different technologies, because sometimes the right technology is the one that has the least life costs rather than just looking at the capex of it.
Life costs include the power required, raw chemicals required, the storage required, the maintenance time, the complexities of the maintenance etc… there are a lot of things to look at, but it usually can be the best way to analyse various disinfection technologies.
