1、 Process selection for large and medium-sized pure water equipment:

According to the customer's water regulations, suitable water production and manufacturing processes can be selected.

If the water body is specified to be less than 10us and the pure water output is less than 3T, reverse osmosis large and medium-sized pure water equipment or ion exchange large and medium-sized pure water equipment can be selected.

If the regulations for water bodies are less than 10us and the total flow rate of purified water exceeds 3T, it is necessary to choose large and medium-sized reverse osmosis pure water equipment. If choosing ion exchange large and medium-sized pure water equipment, its application cost is too high.

If the water body regulation is below 5us, regardless of the total flow rate, two stages of reverse osmosis must be selected for the entire process.

If the pH value is high, it is suggested that ion exchange is not necessary. Ion exchange will change over time, and pH values will also change. Reverse osmosis does not have this problem.

2、 Common problems in selecting large and medium-sized pure water equipment after clarifying the process

If choosing a reverse osmosis process or a two-stage reverse osmosis process, attention should be paid to the construction of the preparatory treatment and the selection of the reverse osmosis membrane. The water flow rate for pre-treatment must be twice that of pure sewage.

If ion exchange technology is applied, high-quality epoxy resin must be selected, and epoxy resin collection equipment must be used to avoid leakage of recycled epoxy resin.

3、 The key process of large and medium-sized pure water equipment:

1. Process steps for reverse osmosis large and medium-sized pure water equipment

Water tank - sewage lifting pump - multimedia system filtration - activated carbon filter - softened water filtration - reverse osmosis server - pure water tank

2. Process of secondary reverse osmosis large and medium-sized pure water equipment:

Water tank - sewage lifting pump - multimedia system filtration - activated carbon filter - softened water filtration - primary reverse osmosis server - primary water tank - high-pressure water pump - secondary reverse osmosis server - pure water tank

3. Ion exchange technology for large and medium-sized pure water equipment:

Water tank - sewage lifting pump - multimedia system filtration - activated carbon filter - cation bed - anion bed - pure water tank
