スタンドアロンまたはROと組み合わせた電気脱イオン。
樹脂ベースのイオン交換システム
UVおよびコロナ放電オゾン衛生システム
In power generation, boiler feedwater purity is a matter of operational survival. Impurities like silica (SiO2), total hardness, and iron are the primary enemies of high-pressure utility boilers. Under extreme temperatures and pressures, even trace amounts of silica can carry over into steam, crystallizing on turbine blades and causing catastrophic equipment failure.
According to ASME Guidelines, as boiler operating pressure scales up toward power plant standards, allowable impurity levels drop to near-zero. Virtually all dissolved solids must be eliminated. ROTEK’s advanced reverse osmosis (RO) technology serves as the critical first line of defense, providing the ultra-low conductivity water required before electrodeionization (EDI) or mixed-bed polishing.

High-Purity RO Feedwater System for Cogeneration Power Plant
Project Overview
A local cogeneration power plant operating high-pressure water-tube boilers required a continuous supply of high-purity makeup water. The raw water contained elevated levels of silica and hardness, threatening to violate strict ASME water quality guidelines and cause scale buildup in the boiler tubes.
To secure the power plant’s continuous power generation and protect the steam turbines, ROTEK engineered a reliable KSRO parallel reverse osmosis system. Serving as the essential pre-treatment stage, the system consistently delivers low-silica, low-conductivity water to ensure safe, stable, and high-efficiency energy production.
Performance & Results
-
Uncompromised ASME Water Quality Compliance
The KSRO system successfully reduces silica and mineral hardness to ultra-low levels, preventing scale-induced hot spots in boiler tubes and protecting expensive steam turbines.
-
Enhanced Downstream Demineralizer Efficiency
By feeding high-quality RO permeate to the downstream polishing demineralizers, the chemical regeneration frequency was cut by 70%, drastically lowering plant operating costs.
-
Continuous 24/7 Power Generation Support
Our smart parallel configuration allows individual KSRO units to undergo routine maintenance or membrane cleaning one-by-one without interrupting the continuous flow of feedwater to the plant.
-
Significant Reduction in Boiler Blowdown
Cleaner feedwater means fewer boiler blowdowns. This saves thousands of tons of high-temperature water and fuel annually, lowering the plant's overall carbon footprint.
