Ideal for power plants, petrochemical facilities, and other steam-intensive industries, GreenPebble Technologies' CPU helps recycle condensate effectively, promoting sustainability and cost savings.

Features and Benefits of GreenPebble's CPU
GreenPebble Technologies' Condensate Polishing Unit is designed with innovative and sustainable membranes and ion exchange resins to deliver reliable performance under high-flow conditions. Below, we highlight key features and their associated benefits, emphasizing our differentiation;
​
Advanced Membrane Technology
Features ultrafiltration (UF) and reverse osmosis (RO) membranes with enhanced pore structures and anti-fouling properties.
​
-
High Rejection Rates: Achieve up to 99% removal of silica and other dissolved impurities, preventing boiler tube fouling.
-
Energy Efficiency: Low-pressure operation reduces energy consumption by 20-30% compared to traditional systems.
-
Durability: Chemically resistant membranes withstand high temperatures and pH variations, extending service life with proper maintenance.
-
Benefit: Minimizes turbine blade erosion and improves overall system reliability, leading to reduced maintenance costs and extended equipment lifespan.
High-Performance Ion Exchange Resins
Integrated mixed-bed ion exchange resins, featuring strong acid cation and strong base anion types, target ionic contaminants with precision. These resins are regenerated externally or in situ, ensuring continuous operation.
​
-
Superior Ion Removal: Effectively eliminates cations and anions - achieving sodium and chloride levels below 2 ppb.
-
Filtration: Resins capture corrosive components, preventing deposition on heat transfer surfaces.
-
Benefit: Enhances boiler efficiency by preventing under-deposit corrosion, resulting in fuel savings of up to 5% and compliance with industry standards like EPRI guidelines.
