1. Circulating Water Scale Inhibitors
Circulating water scale inhibitors are compounded from organic phosphonates, multi-component copolymers, and corrosion inhibitors. These water treatment chemicals deliver excellent chemical stability and thermal stability, with minimal hydrolysis risk. Endowed with superior corrosion inhibition, scale prevention, and scale dissolution performance, they enable circulating water systems to operate safely and stably under harsh conditions: high hardness, high alkalinity, high pH value, and high concentration ratio.
The circulating water system requires long-acting, bacteriostatic solutions. A high dosage of polymer dispersants can be integrated to disperse suspended solids, thereby enhancing overall scale inhibition efficacy. Given the large system volume and open-air operation of circulating water systems, the purity requirements for the inhibitors are relatively low.
Key Benefits: Cost-effective, adaptable to high-concentration environments, ideal for industrial cooling towers and closed-loop water systems.
2. Reverse Osmosis (RO) Scale Inhibitors
RO scale inhibitors are specialty water treatment agents designed exclusively for reverse osmosis systems. Their core function is to prevent scale formation on RO membrane surfaces, improve water production capacity and quality, and reduce long-term operational costs.
Unlike circulating water inhibitors, RO scale inhibitors require rapid reaction with scale-forming ions due to the short contact time in RO systems—high efficiency and fast action are critical. Additionally, the narrow internal channels of RO membranes make polymer dispersants unsuitable, as they can cause membrane fouling and clogging. The scale inhibition process in RO systems involves concentration on the membrane surface; high impurity content in the inhibitor will directly compromise system stability and membrane lifespan.
Key Benefits: Membrane-friendly, high-efficiency scale control, reduces membrane cleaning frequency, suitable for seawater desalination, industrial pure water, and electronic-grade water systems.
