Innodi > About Us

InnoDI – stands for Innovative De-ionization. We are a private limited company established in 2016 as a joint venture between Idropan Dell’Orto Depuratori based in Milano, Italy, AquaSphere Greentech Solutions based out of Bangalore, India and led by IIT Madras through Prof. Pradeep lab.

The three companies have brought in years of experience in water treatment and deep understanding of CDI into InnoDI for large scale commercial production and deployment of this technology in the global markets.

We believe that the power of innovation is felt only when it is delivered to the needy.

We also believe that this power of innovation can sustain only if it can bring a big social, environmental and nutritional impact to the society.

We established InnoDI for this purpose – to continuously research, develop and adapt break-through methods in water treatment using Electro De-ionization technology that supports this belief in delivery and sustenance objectives.

We intend to achieve this goal by developing solutions that are:

  • Decentralized in its deployment, which will ensure we deliver our innovation to the needy – anywhere in the world.
  • Economic in its process and use, which enables us to build a business model that is sustainable and inclusive in nature.
  • Environmentally sustaining in terms of reducing water wastage and energy which otherwise is required – to deliver the healthiest water required for the community.
