CrestoGuard 462

CrestoGuard 462 – Antiscalant for Reverse Osmosis and Membrane Systems

• Type: Antiscalant / Dispersant

• Application: Reverse osmosis (RO), nanofiltration (NF), and ultrafiltration (UF) membrane systems

• Appearance: Clear to slightly yellow liquid

• Solubility:  Completely water-soluble

• Typical Dosage: 2–6 mg/L, depending on feedwater chemistry

Application :

• Prevents formation of calcium carbonate, calcium sulfate, barium sulfate, strontium sulfate, and silica scale

• Effective in high-recovery membrane systems

• Suitable for municipal, industrial, and seawater desalination applications

Description:  
CrestoGuard 462 is a high-efficiency liquid antiscalant designed to inhibit the precipitation of common scaling species in membrane separation systems. It enables extended membrane life and optimal performance by reducing the frequency of chemical cleaning and maintaining consistent permeate flow. CrestoGuard 462 is compatible with a wide range of membrane materials and system configurations.

Key Features:

• Broad-spectrum scale control, including silica

• Compatible with leading membrane brands

• Reduces operating and maintenance costs

• Performs effectively across a wide pH and temperature range

• Non-aggressive formulation – safe for long-term membrane contact
