Boiler Feed Water
Innovative Ceramic Membrane Filtration for Industrial Boiler Feed Water

Why Nanostone for Boiler Feed Water for Power Generation?
Approach & Benefits
Our Ceramic Ultrafiltration Membranes provide an innovative solution to challenges such as source water variability, high turbidity, constrained footprints, among others, in treating boiler feed water, offering several key benefits:

- Compact Footprint: Our solution can fit into the small spaces that are typically available for water treatment equipment in these facilities. This is essential for retrofits and expansions where space is limited.
- Simplified Treatment Scheme: Competing approaches typically use multimedia filtration and polymeric UF membranes. We replace both in a single-unit operation, simplifying the treatment process and reducing the overall footprint and complexity of the system.
- Robust Operation: Our solution is robust against the variability inherent in surface waters often used to supply boiler feed, ensuring consistent performance and quality despite changes in feed water.
- Increased Recovery: Our system achieves higher recovery than competing schemes, resulting in increased uptime and lower overall operational expenses (OPEX). This is achieved through efficient contaminant removal and reduced fouling of downstream RO systems.
- Extended Membrane Life: Our ceramic membranes deliver a longer lifespan, reducing replacement frequency and associated costs.

Common Questions
About our Boiler Feed Water Application
How does Nanostone’s technology improve boiler feed water treatment?
How does Nanostone’s technology improve boiler feed water treatment?
Nanostone’s ceramic membrane technology significantly improves boiler feed water treatment by offering superior filtration performance, even in challenging water conditions. Their membranes effectively remove suspended solids, organic matter, and other impurities that could cause scaling and corrosion in boilers. Unlike traditional polymeric membranes, Nanostone's ceramic membranes are more resistant to fouling and can operate in harsher feedwater conditions without frequent cleaning, reducing maintenance costs and downtime.
How do your membranes help reduce scaling and corrosion in my boilers?
How do your membranes help reduce scaling and corrosion in my boilers?
Nanostone’s ceramic membranes effectively combat corrosion by delivering high-purity feedwater with minimal suspended solids, dissolved gases, and other corrosive contaminants. Their advanced filtration technology ensures that particulates, which could indirectly promote corrosion by interfering with de-aeration or chemical treatment processes, are thoroughly removed. Furthermore, the membranes' superior performance enhances the effectiveness of downstream treatments, such as de-aeration and chemical dosing, providing additional protection against corrosion.
