Sludge precipitated in HP Dosing (TSP) stainer
Today we found some kind of slurry sludge in the HP dosing pump stainer.
What can be the issue related to this?
Attached few photos.
COMMENT BY WATER NETWORK ADMIN (In HP Dosing Phosphate especially Tri sodium phosphate is added at the boiler drum which is operating at high pressure (so called HP dosing system) through HP dosing system. If it is dosed at feed pipe, it may react with impurities and sludge may be deposited at the feed line.)
