Qualified

1. According to the situation of raw water, do a small test before using to obtain the best dose. Small test solution configuration by weight ratio (W / W), generally 2-5% with good. Assembled with 3% solution: said polyaluminum chloride PAC solid 3g, into a 200ml measuring cylinder, add about 50ml of water, to be dissolved and then diluted with water to 100ml scale, shake it.

2. When producing polyaluminum chloride PAC for production, mix and dissolve according to polyaluminum chloride PAC solid:water=1:9 to 1:15 weight ratio. Solutions with a content of alumina less than 1% are prone to hydrolysis and can reduce the effect of use. Concentrations are too high to be easily added evenly.

3. Dosing according to the best dosing amount obtained by small test. For example, if sedimentation tanks are found to be less, if there are large amounts of turbidity, the dosage will be too small. If the sedimentation tank is large and upturned and the remaining turbidity is high, the amount of dosing is too large and adjustments should be made.
