For customers, we often face to these problems such as we spent a higher price for goods which not comparable with the others. From our experience, we will give some suggestion for select high quality PAC with competitive price.

And solid PAC granulate appears flaky and power with light yellow color. And have not sticky pieces. Secondly, by touch. If the result of deliquiesce or evaporation of water is not so clean and clear. The good solid PAC will easily get wet when explored with room temperature. Bewared when storage the products wiht this matter. Thirdly, by testing. Have raw water purification experiment to water which ned to be purified according to the instructions and observe the result. After these three observations, on can clearly knows the PAC whether is good quality, and high efficicent or not.
