Hyderabad-based scientists at the Indian Institute of Chemical Technology (IICT) have pioneered two indigenous technologies that drastically cut dialysis costs by up to 70%, enhancing access to treatment for patients with chronic kidney disease (CKD), especially in rural areas. Already benefiting nearly 20,000 patients through pilot deployments in Kamareddy and Marredpally, these innovations target key dialysis components: haemodialyser filters and high-purity water systems.
The first advancement features ultra-thin hollow-fibre membranes made from polyethersulfone using a novel spinneret design, meeting global standards while slashing filter costs from Rs 700-1,000 (imported) to Rs 150-200 domestically. These microscopic fibres efficiently filter blood toxins while preserving essential proteins, reducing India’s heavy reliance on costly imports.
Complementing this, the second technology employs advanced reverse osmosis (RO) and nanofiltration (NF) membranes to produce ultrapure water vital for safe dialysis, cutting water and electricity use by 25% compared to conventional systems. IICT researchers highlight how these systems prevent water-borne infections and enable even small rural clinics to deliver high-quality care affordably.
Pilot implementations with private dialysis providers have validated real-world performance, paving the way for broader technology transfer. By lowering consumable expenses and import dependency currently at 80% for medical devices, these breakthroughs align with national goals for self-reliant healthcare, making life-saving dialysis more equitable for millions needing regular sessions.
