In a major breakthrough for kidney care, scientists at the Indian Institute of Chemical Technology (IICT) have developed two indigenous technologies that can significantly reduce the cost of dialysis. These innovations aim to expand access to life-saving treatment, especially in rural areas and smaller healthcare centres. Notably, pilot studies have already benefitted nearly 20,000 patients.
Targeting the Key Cost Drivers
As reported by TOI, the researchers focused on two critical components of dialysis—haemodialyser filters and high-purity water systems—which together account for a large share of treatment expenses. By addressing these elements, the team has created solutions that could cut consumable costs by nearly 70%, making dialysis far more affordable for patients with chronic kidney disease.
Affordable, High-Performance Haemodialyser Filters
First, the team developed ultra-thin hollow fibre membranes used in haemodialysers. These membranes act as artificial kidneys by filtering toxins from the blood.
Traditionally, India has relied heavily on imported filters, which has driven up treatment costs. However, IICT’s novel membrane design matches global performance standards while remaining far more cost-effective. While imported haemodialyser filters typically cost between ₹700 and ₹1,000, the indigenously developed versions can be manufactured for as little as ₹150 to ₹200. As a result, patients undergoing regular dialysis could experience substantial financial relief.
Efficient and Sustainable Water Purification Systems
In addition, the scientists tackled another essential requirement for safe dialysis—high-purity water. They developed advanced reverse osmosis (RO) and nanofiltration (NF) membrane systems to ensure effective removal of contaminants.
Moreover, these systems improve operational efficiency by reducing both water and electricity consumption. This makes them not only safer but also more sustainable for long-term use in healthcare settings.
Successful Pilot Deployments
To validate these innovations, researchers conducted pilot deployments in Kamareddy and Marredpally. In collaboration with private dialysis providers, they tested the systems in real-world conditions. Encouragingly, the technologies delivered consistent performance across nearly 20,000 patients.
Scaling Up for Wider Impact
Following the success of these trials, IICT is now in the process of transferring the technology to private service providers for broader adoption. This step will help accelerate the integration of these solutions into routine dialysis services.
Reducing Dependence and Expanding Access
Ultimately, these innovations could play a crucial role in reducing India’s reliance on imported medical devices. At the same time, they can help extend high-quality dialysis services to underserved and remote regions.
With lower costs and improved efficiency, IICT’s technologies have the potential to transform long-term kidney care—ensuring that more patients receive timely, affordable, and effective treatment.
