Product Performance
Reverse Osmosis Membrane Scale Inhibitor PO-100 is a high-efficiency compound-formulated reverse osmosis (RO) scale inhibitor. It delivers excellent scale inhibition performance and has a wide application range, providing effective scale inhibition and dispersion effects for conventional water quality. It is particularly suitable for preventing scaling caused by precipitates of carbonates, sulfates, calcium oxide, magnesium oxide, and iron oxide. With high scale inhibition efficiency, it does not coagulate with residual coagulants or aluminum-rich/iron-rich compounds, and no coagulates will be formed. It prevents scaling in reverse osmosis (RO), nanofiltration (NF), or ultrafiltration (UF) systems without ion exchange pretreatment, thereby improving water production volume and quality.
Product Features
- Effectively controls inorganic scaling within a high concentration range, with a maximum allowable Langelier Saturation Index (LSI) value of 2.8 without acid addition.
- Does not coagulate with iron-aluminum oxides or silicon compounds to form insoluble substances.
- Compatible with various RO membranes (cellulose acetate (CA) and thin-film composite (TFC) membranes), nanofiltration membranes, and ultrafiltration membranes produced by major manufacturers worldwide.
- Effective when the feed water pH ranges from 5 to 10.
Usage Method
- Dosing Point: For optimal performance, PO-100 scale inhibitor should be added before the mixer or security filter. When preparing the chemical solution, stir thoroughly for 5–10 minutes. Clean the dosing tank regularly to prevent bacterial growth.
- Dosing Amount: The required dosing amount is determined by the operating conditions of individual devices and should be calculated based on factors such as feed water salinity, temperature, recovery rate, and type of RO membrane. The recommended dosing amount is 2–6 ppm.
- Please consult Puniao's technical engineers to determine the dosing point and dosing amount based on your specific system conditions. In some systems, specific dosing points and injection equipment are mandatory.
- Dilution: PO-100 scale inhibitor is a standard solution that can be dosed directly or used after dilution. RO product water or demineralized water should be used for dilution. The recommended dilution ratio is 10:1, and the dilution ratio should not exceed 20:1.
Packaging, Storage, Transportation, and Precautions
- Packaging: Packed in plastic barrels, available in 25kg/barrel, 200kg/barrel, or customized packaging according to user requirements.
- Storage: Store in a cool and dry place. The shelf life is 12 months.
- Precautions: Pay attention to labor protection during operation. Avoid contact with skin and eyes. In case of contact, rinse thoroughly with plenty of clean water.
