From Patent to Profit: How Anupam Mukherjee Built Prasinos Into India’s Nanobubble Pioneer
Hyderabad, Telangana, (India), November 11, 2025: When Anupam Mukherjee first started exploring nanobubbles, few believed an Indian company could take on international water technology firms. A decade later, his venture, Prasinos Tech Innovations, has become a national name in advanced aeration systems, proving that innovation built in India can compete on a global scale.
An Idea That Grew Into an Industry Benchmark
Prasinos began with a clear purpose: to create efficient water treatment systems that combine high performance with affordability. What started as an experimental patent on controlled nanobubble generation has grown into a business that now serves multiple industries and municipal operations across the country.
The team achieved a major milestone when they managed to produce bubbles as small as 100 nanometres using a flow-through design that allows continuous operation without clogging or energy loss. This design changed the game, making large-scale nanobubble oxygenation both practical and commercially viable.
The achievement established Prasinos as a true technology developer rather than just a system integrator, a distinction that helped position the company at the forefront of India’s growing clean-tech sector.
Winning Trust in a Competitive Market
Breaking into a market dominated by long-established international suppliers wasn’t easy. Mukherjee and his team had to rely on results rather than reputation. Their opportunity came when a major textile manufacturer in Gujarat agreed to trial the technology in one of its treatment plants.
Within weeks, the plant saw a sharp rise in oxygen transfer efficiency and a 40 per cent drop in energy consumption. The numbers spoke for themselves. Soon, other industries, from pharmaceuticals and food processing to chemical manufacturing, began reaching out. Prasinos’ technology was not only more efficient but also simpler to maintain and cost-effective to run.
From Aquaculture to Industry: A Natural Evolution
The company’s first success came in aquaculture, where stable oxygen levels determine productivity. The performance in ponds and hatcheries proved the robustness of the system and opened the door to industrial use.
Today, the same nanobubble technology is being used to revitalise effluent treatment plants (ETPs) and sewage treatment plants (STPs). Operators have reported lower sludge volumes, faster treatment cycles, and reduced chemical dependency, all without needing to overhaul existing infrastructure.
Made in India, Competing With the World
Prasinos has built all its systems under the Make in India initiative, sourcing components domestically and designing every element in-house. Competing successfully with imported systems from Japan, Europe, and the United States, the company has shown that advanced manufacturing and cost efficiency can go hand in hand.
“Our goal was not just to develop new technology,” says Dr. Anupam Mukherjee. “We wanted to prove that cutting-edge engineering can be designed, built, and perfected in India.”
“Innovation for us has always been about solving real, on-ground problems,” says Dr. Aditi Mullick, co-founder of Prasinos. “When we designed our nanobubble systems, our goal wasn’t just efficiency; it was reliability. We wanted technology that could work in India’s most challenging water conditions, run continuously, and deliver consistent results. That’s what makes it meaningful.”
A New Face of Indian Innovation
Under Anupam Mukherjee’s leadership, Prasinos has grown from a single-patent startup into one of India’s most recognised names in nanobubble applications. Its journey from research to real-world impact reflects a broader shift in India’s industrial identity, from technology importer to technology creator.
For Mukherjee, the company’s success is about more than business. It’s a demonstration that Indian science and entrepreneurship, when combined with persistence and purpose, can deliver solutions that rival the best in the world.
