SpectraGuard antiscalants are a good choice for preventing scale formation in reverse osmosis water treatment systems. All products are phosphate-free, which makes them more sustainable than products containing phosphates.
SpectraGuard 100 is the most economical option, but may require frequent dosing in very hard water.
SpectraGuard 111 is a more concentrated option than SpectraGuard 100, which makes it more effective and reduces the need for dosing.
SpectraGuard 250 is a high performance product that is effective in a wide range of conditions.
SpectraGuard 311 and SpectraGuard 360 are high-performance products that are designed for specific applications.
The best choice for a specific application will depend on specific factors, such as water type, water hardness and budget.
Characteristics:
- Prevents the accumulation of minerals, such as calcium carbonate, calcium sulfate, barium sulfate, calcium fluoride and silica.
- It is compatible with all types of membranes and their components.
- It has a concentrated formula that reduces freight and inventory costs.
- It is easy to use and apply.
Benefits:
- Prolongs the life of reverse osmosis membranes.
- Improves the quality of the water produced by the reverse osmosis system.
- Reduces the need for membrane cleaning and maintenance.

Description of each of the reverse osmosis membrane antifoulants
SpectraGuard 100
It is a high quality, ready-to-use antiscalant / dispersant liquid approved for pretreatment of water supply for reverse osmosis systems. This product is capable of handling high levels of carbonate, sulfate and silica scale, as well as low iron concentrations, which stabilizes the chemical control performance of the water supply. In addition, the SpectraGuard™ 100 formula does not contain phosphates/phosphonates, which helps reduce its negative impact on the local environment. This product can be mixed with other pretreatments, such as PWT’s BioGuard™ and OrganoGuard™, which reduces equipment dosing and makes it ideal for use in seawater, well water and surface water supplies.
SpectraGuard™ 100 is Kosher and Halal certified.
Advantages and Features:
- Its phosphate-free formula contributes to the preservation of the environment.
- Its resistant molecular structure maintains its effectiveness even under conditions of high pH, high temperatures and high salinity.
Antifouling applications:
- Controls the formation of calcium carbonate, calcium sulfate, barium sulfate, calcium fluoride, silica, as well as iron and aluminum hydroxide.
- It can be mixed with other PWT formulations for pretreatment, which reduces the amount of product needed.
SpectraGuard 111
SPECTRAGUARD™ 111 is a high quality 11x ultra-concentrated antiscalant approved for RO (reverse osmosis) pretreatment. With its ability to descale high levels of carbonate, sulfate and silica scale, as well as low iron concentrations, SPECTRAGUARD™ 111 stabilizes performance through control of water supply chemistry. The 11x Super Concentrated formula significantly reduces shipping and storage costs, making it ideal for small installations and international shipments. SPECTRAGUARD™ 111, with its phosphate/phosphonate-free formula, minimizes its impact on the environment. It can be mixed with other pretreatment products such as BioGuard™ and OrganoGuard™, reducing equipment dosage. Suitable for seawater, well water and surface water supply.
