Product Description
PAPEMP is a next-generation organophosphonate water treatment chemical featuring excellent chelating, dispersing, scale inhibition, and calcium tolerance properties.
It is particularly suitable for demanding water treatment systems operating under high hardness, high alkalinity, and high-pH conditions.
PAPEMP can be used as a combined scale and corrosion inhibitor for industrial circulating cooling water systems and oilfield water treatment.
It provides excellent inhibition of calcium carbonate, calcium phosphate, and calcium sulfate scale, while also offering effective control of silica scale formation.
PAPEMP also has a strong ability to stabilize metal ions such as zinc, manganese, and iron, helping improve the overall performance and stability of formulated water treatment programs.

Application Scenarios
1. Industrial Circulating Cooling Water
PAPEMP can be used as a scale and corrosion inhibitor in industrial circulating cooling water systems.
It is particularly suitable for systems with:
· High water hardness
· High alkalinity
· High pH
· High concentration cycles
· High mineral scaling potential
PAPEMP provides comprehensive control of carbonate, phosphate, sulfate, and silica-related deposits.
2. Oilfield Water Treatment
PAPEMP is suitable for oilfield water treatment and water injection systems, particularly where high hardness, high mineral content, and difficult scaling conditions are encountered.
Its high calcium tolerance makes it suitable for challenging water chemistries where conventional scale inhibitors may have limited performance.
3. Reverse Osmosis Membrane Systems
PAPEMP can be used as an antiscalant for reverse osmosis (RO) membrane systems.
It helps control the formation and deposition of sparingly soluble mineral salts on membrane surfaces, helping maintain membrane performance under demanding feed-water conditions.
4. Multi-Stage Flash Desalination
PAPEMP can be used in multi-stage flash (MSF) desalination systems and other high-salinity water treatment processes.
Its scale and corrosion inhibition properties make it suitable for applications involving:
· High salt concentrations
· High temperatures
· High turbidity
· High mineral scaling potential
