PO-143 Phosphorus-Free Reverse Osmosis Membrane Scale Inhibitor

Product Performance

PO-143 reverse osmosis membrane scale inhibitor is a high-efficiency compound phosphorus-free alkaline liquid scale inhibitor/dispersant. It is used to control scale deposition in membrane separation systems and reduce the possibility of particulate re-fouling on the membrane surface. Meanwhile, it can effectively inhibit the scaling of carbonates, sulfates, calcium fluoride, metal oxides and other substances on the concentrate side.

Product Features

It complies with ANSI/NSF 60 Certification standards for drinking water applications.

Its phosphorus-free formula largely mitigates microbial contamination in the first stage of RO systems.

It is suitable for all major reverse osmosis and nanofiltration membranes, allowing a wide feed water pH range and high temperature tolerance.

It boasts excellent performance, is environmentally friendly, contains no phosphorus and ensures high safety for reverse osmosis systems.

It is compatible with various types of reverse osmosis CA and TFC membranes, nanofiltration (NF) membranes and ultrafiltration (UF) membranes produced by major global manufacturers.

Technical Specifications

Application Method

Dosing Point

To achieve maximum efficiency, it is recommended to add PO-143 phosphorus-free scale inhibitor before the mixer or cartridge filter. Stir thoroughly for 5–10 minutes when preparing the chemical solution, and clean the dosing tank regularly to prevent bacterial growth.

Dosing Amount

The required dosing amount is determined according to the operating conditions of individual units. A suitable dosing amount shall be calculated based on such conditions as feed water salinity, temperature, system recovery rate and the type of RO membrane. The recommended dosing amount is 2–6 ppm.

Please consult Prio technical engineers to determine the dosing point and dosing amount for your specific system conditions. Specific dosing points and injection equipment are required in some systems.

Dilution

PO-143 phosphorus-free scale inhibitor is a standard solution that can be dosed directly or used after dilution. RO product water or demineralized water shall be used for dilution. The recommended dilution ratio is 10 times, and the dilution ratio shall not exceed 20 times.

Packaging, Storage, Transportation and Precautions

Packed in plastic drums, with specifications of 25kg/drum, 200kg/drum or customized as per customer requirements. Store in a cool and dry place with a shelf life of 12 months. Pay attention to labor protection during operation; avoid direct contact with skin, eyes and other mucous membranes. In case of contact, rinse the affected area thoroughly with plenty of clean water.
