How about Zhengzhou AIA pure water equipment?

I bought a set of purified water equipment from AIA, the model number is YB-CJS-00 1. The equipment has been used for 2 years, running well and the effluent is stable. Probably because I use a lot of water, the quality of raw water is poor and the amount of sediment is large. The filter element is replaced once a week, and a new bag filter is installed in the technical proposal. The water quality is good and satisfactory. Durable equipment, energy saving and environmental protection.
