In addition to the urea system contains what dosing equipment

Liquid dissolution and dispensing system, metering and dosing system, safety system, control system. In the biochemical treatment system, usually wastewater before entering the biochemical tower to adjust the relevant indicators, urea can be used to adjust the nitrogen content, supplement the nitrogen source, in the biochemical pool of the proportion of the value of C: N: P = 100: 5: 1. Urea dosing device dosing equipment system mainly includes liquid dissolution system, metering dosing system, safety system and control system and other four parts. In the sewage treatment process, the need to add urea to adjust the ratio of nutrient solution in the sewage, C: N: P, the ratio adjustment.
