Webflow (usually of water) is monitored by the flow meter, which in turn controls a metering pump. In this way, a chemical can be injected at a rate which matches the flow, for uniform concentration. Flow pacing can be done in one of four ways: • Pulse meter and pulse-responsive pump • Flow meter, counter/timer, and continuous-running pump WebGeneration of chlorine dioxide using 3-chemical sodium chlorite, bleach, and hydrochloric acid chemistry. Chlorine dioxide is very water soluble (more so than chlorine gas), and even at the max 3000 ppm concentration (equivalent to 0.3% by wt. and 99.7% by wt. water), the risk of degradation is low unless concentrated chlorine dioxide gas in air is exposed to a …
