 I. Product Overview

Product Name: Reverse Osmosis (RO) Scale Inhibitor

Product Description: This product uses a composite formulation of nitrogen free and phosphorus free water soluble polymers and polycarboxylic acid substances, which overcomes the shortcomings of single component agents. Through synergistic effects, it enhances scale inhibition performance, effectively extends membrane device service life, and reduces membrane module maintenance costs.

 II. Product Applications and Production Capacity

Application Fields: Electric power, petrochemicals, environmental protection and energy, seawater desalination, food and beverage, biopharmaceuticals, municipal drinking water, electronic chips, textiles and papermaking, etc.

Scope of Application: Suitable for processes using reverse osmosis and nanofiltration membrane systems, such as boiler feedwater, desalination of high salinity wastewater, seawater desalination systems, wastewater reuse, ultrapure water production, and mine water treatment.

Production Capacity: The facility is equipped with various production processes including constant temperature reaction, polymerisation, modification, compounding, purification, and concentration, with an annual production capacity of 12,000 tonnes. An in house quality inspection centre and modern logistics ensure the quality of end products.

 III. Product Performance Advantages

Highly efficient scale inhibition, reducing membrane module maintenance costsby 15%–30%.Phosphorus‑free, green, and biodegradable.Broad pH tolerance.Wide membrane compatibility.Wide operating temperature range.Suitable for complex water quality conditions.

Chelation and Solubilisation Technology: The negatively charged groups dissociated from the scale inhibitor molecules chelate with scale forming ions (Ca²⁺, H₄SiO₄) in the solution, generating stable chelates that increase the solubility of sparingly soluble salts.

Dispersion Effect: The anions dissociated from the scale inhibitor in water collide with calcium carbonate microcrystals, imparting a negative charge to the crystal surfaces, thereby causing dispersion. Through micro interface regulation technology, calcium silicon particles are dispersed, reducing particle growth.

Chelation and Solubilisation Technology: The negatively charged groups dissociated from the scale inhibitor molecules chelate with scale forming ions (Ca²⁺, H₄SiO₄) in the solution, generating stable chelates that increase the solubility of sparingly soluble salts.

Synergistic Protection System: By combining two or more scale inhibitors, their synergistic effects improve scale inhibition performance, compensate for the deficiencies of single agents, and strengthen the capability to handle complex water qualities and mixed fouling conditions.

 IV. Intellectual Property

A phosphorus free environmentally friendly reverse osmosis scale inhibitor and its preparation method, Patent No.: ZL202512018415.2
