Description and Use
aqualead MF788 Plus, a multi-functional reagent, conditioning water against deposits and corrosion in the water supply and the steam generator.
aqualead MF788 Plus is suitable for boilers supplied with softened water that has not been thermally deaerated and for flooded boilers.
Typical Applications
Phosphorous derivatives prevent scaling by sequestering Calcium and Magnesium cations, thus ensuring a clean exchanger surface for maximum coefficient of heat transfer.
Phosphorous derivatives act as corrosion inhibitors by passivation of metallic surfaces, ensuring long term plant life and availability.
Polymeric dispersants prevent blockages by keeping any particles or precipitates in suspension, such as Ca and Mg salts and iron oxides.
Powerful oxygen scavenger prevents corrosion by reducing the presence of dissolved oxygen.
As a one-shot treatment, aqualead MF788 Plus simplifies addition and facilitates easier stock control.
Treatment and Feeding Requirements
aqualead MF788 Plus should be dosed according to the oxygen content dissolved in the supply water. Dissolved oxygen content is a function of water temperature.
The generally recommended dosage is 63 g/m3 of nondeaerated supply water per mg/L of dissolved oxygen in

Please contact us via:
www.veoliawatertechnologies.comorder to maintain an oxygen scavenger and P2O5 residuals in the boiler, variable according to the pressure, type of boiler, and the manufacturer’s standards.
aqualead MF788 Plus is designed to be added as supplied. The product should be dosed via a positive displacement pump ahead of the degassing circuit. This allows the oxygen scavenger sufficient time to react and eliminate dissolved oxygen.
In all cases our engineers and technicians are available to carry out an in-depth study to recommend the optimum dosage and conditions of use.
In addition to the purification and observance of standards in the boiler as recommended by the manufacturer, treatment by aqualead MF788 Plus only requires the evaluation of the oxygen scavenger excess.
Storage and Handling
During manipulation, it is necessary to wear at least protection glasses and adapted clothing and gloves. It is imperative to refer to the safety data sheet.
aqualead MF788 Plus should be stored in its original packaging in a cool, dry location (10-25 °C).
aqualead MF788 Plus has a shelf life of at least 24 months when stored under the recommended conditions.
