The document is a cover letter from a Water Research Engineer applying to work with Power Tech Water. The engineer developed an eco-friendly catalyst for removing nitrates from water through their master's research. They believe catalyst-based water treatment can replace existing methods while overcoming losses. They are interested in working with Power Tech Water to understand how to commercially apply water treatment technology and help develop and optimize the technology while addressing commercialization challenges.

1. Cover letter
Dear Team,
Congratulations on your success at ‘Clean Energy Trust’ challenge – 2017. I have come to know
about your team and really like your passion to develop and commercialize new technologies to
treat water. I have similar enthusiasm and would love to work with your team.
Who am I?
I’m a Water Research Engineer at Seoul National University, developing bubble based In-situ
remediation technology for ground water treatment. (To remove organic pollutants)
What is my idea of future water treatment technology?
‘Catalysis’. As part of my Masters research I developed an ecofriendly catalyst, improved its
reactivity, by product selectivity, stability and checked it at the real site to remove anions from
water. It worked! All the nitrate (>30 ppm) was removed and catalyst was retrieved for further use.
Why ‘Catalysis’ and not other technologies?
Compared to the other in-situ methods (bio remediation, aeration, flocculation etc) Catalyst based
treatment is fast, has complete removal, easy reaction design to improve selectivity, catalyst can
be easily regenerated, simple maintenance and low cost.
A catalyst can be designed in such a way that it can react with multiple pollutants and make them
to useful products.
What do I want to do with this upcoming technology?
‘Commercialize it’. For the coming years I believe Catalyst based water treatment can replace
existing ion exchange, adsorption and membrane based water treatment methods while
overcoming the loses.
So why ‘Power Tech Water’?
As a technology startup your team is devoted to both development and commercialization of new
water treatment technologies. I always wanted to know how can you make a technology
commercially viable? What could be the challenges here? Making a patent of your research is

2. different from making it being applied. Working with your team, I want to know how can water
treatment technology be made more suitable for commercial application.
What do you want to do at Power Tech Water?
I have chemistry background about pollutants and their properties and how can we design a
reaction with a new catalyst which converts the pollutant to useful product. As an engineer, I can
design the type of reactor optimize the reaction parameters to enhance the removal process. I
believe I can give technological inputs for development of water treatment technology.
But I don’t just want to limit myself to developing technology, I want see this technology being
accepted and applied and what could be the possible challenges during this process, how to
overcome them and being able to provide clean water.
