What is the main function of KR-0100?

The main function of KR-0100 is as a highly effective antiscalant and dispersant specifically designed for membrane systems, primarily Reverse Osmosis (RO), as well as Nanofiltration (NF) and Ultrafiltration (UF) .

Its primary purpose is to prevent the formation of scale on membrane surfaces, which helps maintain system efficiency, increase water production, and extend the lifespan of the membranes .

Key Functions & Benefits

KR-0100 works by inhibiting and dispersing a wide range of potential foulants. Here are its main functions:

Function Description / Benefit Key Details / Performance

Scale Inhibition Prevents the formation and deposition of common and difficult inorganic scales on membrane surfaces. Effectively controls calcium carbonate, calcium sulfate, barium sulfate, and strontium sulfate scales, often at up to 100x saturation.

Silica Control Retards the polymerization and precipitation of silica, a challenging scale component. Allows for effective operation with silica concentrations up to 290 mg/L in the concentrate stream.

Metal Oxide/Heavy Metal Control Stabilizes metals like iron, aluminum, and other heavy metals in the feed water, preventing them from depositing onto the membrane. Particularly effective in feedwaters with high levels of metal oxides; can tolerate iron concentrations up to 8.0 mg/L in the feed.

Dispersion Disperses suspended particles and colloidal matter, keeping them from agglomerating and fouling the membrane surface. Does not flocculate with dissolved polymers, residual coagulants, or iron/aluminum-rich silica.

Key Features and Usage

Membrane Compatibility: It is compatible with all major brands of CA, TFC, and other RO, NF, and UF membranes .

Operating Conditions: It is effective over a wide pH range of 5.0 to 10.0 . It allows for system operation without acid addition up to a Langelier Saturation Index (LSI) of 2.8 .

NSF Certification: It is certified under ANSI/NSF Standard 60 for use in systems producing drinking water, confirming its safety and compliance with health effects standards .

Typical Dosage: The effective dosage range is generally 1–15 mg/L, with a common recommendation of 3-5 mg/L depending on the feed water quality and system design .

Application Point: It should be injected into the feed stream before the cartridge filters and static mixer .

In summary, KR-0100 is a versatile and powerful tool for ensuring the reliable and efficient operation of membrane-based water treatment systems by preventing a broad spectrum of scaling and fouling issues.
