OptiClean™ S

OptiClean™ S by PWT (USA) is a low pH (acidic), powdered membrane cleaner developed specifically for the removal of silica and other inorganic scales from RO, NF, UF, and MF membranes. Silica is one of the most difficult foulants to remove, but OptiClean™ S effectively targets and breaks down stubborn silica deposits, restoring membrane performance and prolonging membrane life.

During system operation, membrane elements often accumulate foulants, especially silica scaling — known for its resistance to conventional cleaning. If not cleaned regularly, silica deposits can reduce membrane performance, increase operating costs, and shorten membrane life.

To solve this issue, OptiClean™ S was specifically designed with a phosphate-free formula to aggressively remove silica scale while maintaining membrane integrity and system performance.

2. Uses of OptiClean™ S

Maintaining optimal performance in membrane water treatment systems requires regular clean-in-place (CIP) procedures to remove accumulated foulants. OptiClean™ S not only removes silica scaling but also eliminates other inorganic compounds in membrane systems, helping to ensure efficient and stable operation. Key uses include:

Removes silica and other inorganic scale, restoring membrane performance.
Prevents water flow decline, maintaining system efficiency.
Prolongs membrane lifespan, reducing the frequency of replacements.
Minimizes inorganic buildup, ensuring stable long-term system operation.
Compatible with various membrane types (RO, NF, UF, MF), offering flexibility in application.

3. Key Advantages of OptiClean™ S

OptiClean™ S offers not only powerful cleaning performance but also a range of outstanding advantages, helping to optimize system maintenance in water treatment operations:

Specialized formulation breaks down silica scale, quickly removing even tightly bonded deposits.
Rapidly dissolving powder, easy to mix and apply with minimal downtime.
Phosphate-free composition minimizes environmental impact.
Safe for membranes and equipment; does not damage membrane materials.
For enhanced removal of non-silica inorganic scaling, consider using OptiClean™ A+, or pair with OptiClean™ B+ for comprehensive system cleaning.
NSF/ANSI 60 certified – safe for applications in the food and beverage industries.
