Polyluluminium chloride

1. Sagaguation vaega o polylulminium chloride:It is the process of rapid coagulation of the liquid into the coagulation tank and the raw water to form a fine silk flower in a very short time. E tusa lava pe o le vai e sili atu le tuʻinanau. E manaʻomia le tafe vai e faʻaola ai se vevesi. O le polyluminium chloride chloride faʻataʻitaʻiga e tatau ona vave (250-300 r / min) faaosofia 10-30s, e le sili atu nai lo le 2migiga lautele

2. Flocculation vaega o polylulminium chloride:O le faʻagasologa o le tuputupu aʻe ma le mafiafia o lak fugalaʻau. Talafeagai tikeri o le vevesi ma lava le taimi malolo (10-15 min) manaomia. Mai le taimi mulimuli ane, e mafai ona matauina o se aofaʻiga o fugalaʻau fugalaʻau lemu ma fai se laʻau manino. The pac beaker experiment was first stirred at 150 rpm for about 6 minutes and then stirred at 60 rpm for about 4 minutes until it was in suspension.

3. Faʻatulagaina Vaega o Polylulutium chloride:O le tala pepelo lea o le faʻauiga o le faʻasologa i totonu o le sedigenition tane, o lea e manaʻomia ai lemu vai tafe. In order to improve the efficiency, inclined tube (plate type) sedimentation tank (preferably float flocculation is used to separate the flocs) is used to increase the efficiency. It is blocked by the inclined pipe (board) and deposited on the bottom of the tank. The upper layer of water is clarified. The remaining small-sized and small-density alfalfa gradually descends while continuing to collide with each other. The pac beaker experiment should be stirred at 20-30 rpm for 5 minutes, then left for 10 minutes, and the remaining turbidity should be measured.
