How to distinguish process water from soft water
Thread Content
Pipeline numbering was carried out recently. May I ask: 1. How can process water and soft water be distinguished? For example, the soft water (slightly acidic) recovered in the system is used as washing water – should the code for such washing water be PW or SW, or something else? 2. The condensate water from the heat exchanger is used as the circulating water for the water ring vacuum pump – what is its code? Thank you
I think it is based on the source of the water; recycled water should be collected in tanks before being used as washing water. We classify it as WW2 according to wastewater standards. Similarly, based on its source, it should be classified as CW
