Stanrose® BWT Coagulant

Stanrose® BWT Coagulant prevents the formation of deposits on boiler internal surfaces. Sludge is kept dispersed in small particles and conditioned to be removed by normal blowdown. In this way tube overheating due to deposits is avoided. The product is a liquid so is easy to feed to the affected area. The treatment is primarily used in conjunction with Hardness Control, but also with other Stanrose® chemical treatments. Stanrose® BWT Coagulant can also be used where minor oil contamination has been experienced, the oil being required to be coagulated for removal by blowdown.

Recommended Uses

Stanrose® BWT Coagulant prevents the formation of adherent deposits and sludges in boilers and thereby reduces clean-downs.

Method of Application

Stanrose® BWT Coagulant is a physical dispersant product that prevents the formation of large particles in liquid. It functions by keeping solids as small particles and prevents agglomerations from forming.
Stanrose® BWT Coagulant is primarily used in conjunction with HARDNESS / PHOSPHATE CONTROL. The solids can be removed by the blow down as usual.
In addition Stanrose® BWT Coagulant can help to remove small amounts of oil contamination if it arises, by blow down. Oil contamination must of course be stopped if it has arisen.
Normal dosage is 20ml daily/tonne of boiler water capacity. Typically this equates to 0.1-0.3 litres/day. This is the recommended initial dose.
Stanrose® BWT Coagulant should be dosed directly to the boiler via the bypass pot feeder installed in the boiler feed water line.

Storage and Handling

Keep away from heat, sparks and open flame. Ensure that the working area is well ventilated.
Store at moderate temperatures in dry, well-ventilated area.
