Use biocides safely. Always read the label and product information before use. WTP PAA undiluted is a powerful oxidising agent. It is heat sensitive above 60ºC – spontaneous decomposition may occur. Contact with brass, bronze, chromium, copper, iron, lead, manganese, nickel, silver, zinc and other catalytic metal will accelerate decomposition. Contact with concentrated acid, alkalis reducing agents, dirt, ash, rust or metal dust will also cause spontaneous decomposition. Therefore these materials must be absent in transfer pumps and pipework. (Please refer to Material Safety Data Sheets for detailed handling and storage information).


WTP PAA treatments are shipped in 25 litre vented drums.  


Field Representatives will work closely with customer personnel to assure the effective application of the water treatment programme. Regular service calls can be provided by qualified personnel.
