Cost-effective remineralisation of purified sea water that reduces corrosive effects on water infrastructure


A Singapore water technology startup has developed a process to quickly and cost-effectively remineralise purified water under controlled conditions. The process enriches purified water with calcium and magnesium, reducing its corrosive effects on water infrastructure. The startup is seeking commercial or technical partnerships with SME of all sizes, MNEs (Multinational Enterprises) or government organisations.

Partner sought

The type of partner desired would be a government organisation or an SME of any size or MNE in the water treatment industry. Interested types of partnerships include commercial agreement with technical assistance or technical cooperation agreement where partner can engage the Singapore startup for its support and services,


In places that lack low-cost and reliable access to fresh water sources, purification of water from seawater is required to produce potable water. Reverse Osomosis (RO) for desalination seawater strips the water of minerals. Such poorly buffered water is aggressive to the infrastructure used for the storage and transport of water, as well as to plumbing systems, increasing costs required to maintain and replace these systems. Purified water can be remineralised by blending the purified water with treated source water from seawater. However, this requires construction of additional pipe networks, provides less control over the final mineral content and ratio and leaves an undesirable salty and rusty taste in drinking water. The technology developed by the Singapore startup is able to remineralise demineralised water with Calcium, Magnesium, Potassium and Sodium and reduce corrosive effects on water infrastructure. The startup is seeking commercial or technical cooperation agreements with SMEs of all sizes, MNEs or government organisations. The partner can engage the support and services of the Singapore startup for its own organisation or customers.

Advantages and innovations

The technology can be implemented in water purification plants as part of the post-filtration treatment process to enrich purified water with Calcium and Magnesium. The startup is able to provide a means to create a proper balance of Calcium and Magnesium in drinking and cooking water. It has demonstrated a Proof-of-Concept that Low Value RO water can be valued-added into High Value Mineral Water. The technology can also provide a unique combination of features, elements, processes components and design to attained a desired minerals level. The startup has also devised a way to circumvent the dangers associated the Calcium and Magnesium chemical processes. The reduced corrosive effects of remineralising purified water on water infrastructure with the technology can also contribute to: i) improved health ii) better-tasting drinking water and iii) precise control of minerals levels in treated water.

How it works

  • Tell us about yourself
  • We’ll discuss with you
  • We put the right partners in touch

EEN help you find the right partner, rather than you going it alone.

Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.

These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.

Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
