Many thanks for sharing your knowledge. Very good video. I am new to chemical Dosing on water treatment plants so very useful indeed. We have two 27m3 tanks to make up a lime slurry for a 135 MLD water treatment plant.
Thanks for the video. I understand how hydrated lime can lose it's water and get "burned", but what is the processus of drowned lime ? What is the effect of too low a temperature in the mixture and how does it affect/ prevent the full hydratation process of quicklime ?
Drowning lime is a process that is highly undesirable. "Drowning" the reaction adds cold water before the reaction has fully completed. Lower temperatures lead to larger particles, less surface area and poor utilization of the lime. Bottom line is, with cold water you use +10% more lime and you increase your sludge production. It doesn't cost any more money to operate at a higher temperature so the question really is, "why use cold water at all ?"
Excellent demonstration of lime slaking reaction. As a chemical engineer I liked the entire exercise....!👆👍👏😊🌹

Very nice
What is ideal residence time for lime slaking reaction with 65% available CaO in quick lime and water with 80deg C temp..?
using this precise mixing method to make 4% slurry to dose a home reef tank for alkalinity, calcium and high ph effect :)
