The gap between industrial demand and treatment performance has made advanced oxygenation technology a priority. Cleaner discharge, lower power use, and reduced sludge generation now directly influence operational costs and compliance reliability.
The Challenge with Conventional Aeration Systems
Most ETPs and STPs in India still rely on conventional aeration methods that achieve only about 20 percent oxygen transfer efficiency. As a result, many operate at roughly 60 percent of their design performance.
To compensate, operators extend runtimes, increase energy use, and add more chemicals, yet still face unstable dissolved oxygen levels, odour issues, and high sludge production. The combination makes both compliance and cost control difficult.
Nanobubbles Offer a Practical Alternative
Hyderabad-based Prasinos Tech Innovations, India’s pioneer in providing one-stop solution for water and wastewater treatment offers its patented “Make in India” nanobubble technology that addresses these challenges directly.
The company’s aeration units generate nanoscopic bubbles, less than 100 nanometres in size, that remain suspended in water for extended periods. This allows oxygen transfer efficiency to reach nearly 85 per cent, over four times higher than conventional systems. The result is stronger biological activity, faster treatment cycles, and significantly reduced energy consumption.
Proven Gains Across Industries
Industrial users across the textile, chemical, pharmaceutical, and food processing sectors have reported notable improvements after implementing Prasinos systems. Energy use has dropped by up to 40 per cent as aeration runtimes shortened, and overall treatment times have fallen by as much as 40 per cent.
At a textile plant previously struggling with colour removal and COD reduction, chemical oxygen demand dropped by about 70 per cent, while colour removal exceeded 90 per cent. The facility also reduced monthly chemical costs by ₹4–6 lakh and cut sludge generation by nearly one-third.
In the pharmaceutical sector, plants dealing with complex organic compounds reported improved biodegradability indices from 0.2 to 0.45, making wastewater easier to treat biologically instead of relying on costly chemical oxidation.
Municipal and Food Sector Success Stories
The technology’s impact extends beyond industry. Municipal STPs operating at around 1 MLD capacity have reported annual savings of ₹10–12 lakh in operating costs while maintaining BOD levels below 20 mg/L, comfortably within discharge norms.
Food processing units have reduced cleaning frequency by 40 per cent and eliminated persistent odour problems that once affected nearby communities.
Retrofitting Without Major Infrastructure Changes
One of the key advantages of the Prasinos system is its compatibility with existing infrastructure. The technology can be retrofitted into most treatment plants without the need for civil modifications.
The design has no moving parts, minimising mechanical wear and downtime. Built under the “Make in India” initiative, these systems cost three to five times less than imported equivalents, making advanced oxygenation accessible to mid-sized facilities.
Redefining Water Treatment Economics
By combining energy efficiency, lower chemical use, and improved discharge quality, nanobubble aeration is changing how industries view wastewater management. Plants that previously operated near non-compliance are now meeting standards comfortably while reducing costs.
“Facilities that once struggled to meet environmental norms are now well within compliance and saving money in the process,” said Dr. Aditi Mullick, founder of Prasinos Tech Innovations. “This shift turns water treatment from a regulatory burden into a business advantage.”
A Shift Towards Sustainable Industrial Operations
With regulatory pressure rising and freshwater resources under strain, efficient wastewater treatment is becoming a strategic priority. Technologies such as nanobubble aeration demonstrate that environmental performance and economic efficiency can align.
As more facilities adopt these systems, India’s manufacturing sector is beginning to treat water management not as an afterthought, but as an integral part of sustainable growth.
