At IFAT India 2026, high-TDS water treatment emerged as an important solution addressing India's evolving water-treatment needs.
Held in Mumbai from September 9–11, IFAT India 2026 brought together more than 500 exhibitors and 20,118 business visitors from across the water, wastewater, waste management, and recycling sectors. Among the technologies showcased was a solution specifically designed for high-TDS water treatment, with a focus on increasing water recovery while reducing energy use and operating costs.
This focus points to a practical challenge facing water-treatment systems: as TDS increases, treating and recovering water can become more demanding.
High TDS Changes the Treatment Challenge
High-TDS water is not simply another water-quality issue.
Higher concentrations of dissolved solids can create more demanding operating conditions for treatment systems. As the concentration of salts and other dissolved substances increases, maintaining water recovery, controlling energy consumption, and managing operating costs can become more challenging.
For industrial water treatment, this shifts the focus beyond simply achieving a target salt-rejection rate.
The bigger question becomes: Can the membrane maintain stable performance under demanding feedwater conditions while supporting efficient water recovery?
This is where membrane performance becomes increasingly important.
High TDS → Demanding Conditions → Membrane Performance → Water Recovery → Energy Efficiency → Operating Cost
From Water Treatment to Water Recovery
The high-TDS solutions presented at IFAT India 2026 reflect a broader direction in water treatment: the goal is increasingly not only to treat water, but also to recover more usable water from challenging sources.
This makes membrane technology an important part of the equation.
For RO systems, performance under demanding conditions can influence:
Salt rejection
Permeate flow
Operating pressure
Water recovery
Fouling control
Cleaning frequency
Long-term operating stability
The right membrane therefore needs to do more than deliver high rejection under ideal conditions. It needs to support stable and reliable performance throughout real-world operation.
Designed for High-Salt Water
HJC develops RO membrane solutions with demanding water conditions in mind, across residential, commercial, industrial, seawater, and TFN membrane series.
A key technology across HJC's membrane portfolio is its exclusive 4-layer membrane technology. The multi-layer membrane structure is designed to enhance membrane durability and provide greater resistance under demanding operating conditions, supporting more stable and durable performance when treating high-salt water.
The HJC 3G Series for residential RO systems, for example, can handle feedwater with TDS levels of up to approximately 4,500 ppm, providing a solution for applications where conventional residential RO membranes may face more challenging feedwater conditions.
By applying its 4-layer membrane technology across different membrane solutions, HJC continues to develop membranes built around the demands of real-world water conditions.
This approach reflects a simple principle: Higher-TDS water requires membrane technology built for greater demands.
Built Around Real-World Water Conditions
The discussion around high-TDS treatment at IFAT India 2026 highlights an important direction for the water-treatment industry: improving water treatment is not only about removing salts, but also about achieving reliable performance, efficient water recovery, and sustainable operating costs.
For HJC, this reinforces our continued focus on membrane technology engineered for challenging water conditions.
