Monoclor® RCS Chloramine Management and Smartboost® Free Chlorine Management Overview


Monoclor<sup>®</sup> Trailer

Monoclor® RCS Pilot Trailer

The Monoclor® RCS chloramine management system generates a constant and reliable chloramine residual within the reservoir by creating a homogeneous mixture, introducing chemicals rationally and monitoring the equilibrium with control logic in real time. SmartBoost® systems accomplish the same result for distribution systems that utilize free chlorine residuals. These systems accomplish all of this automatically with many on-line reporting and alarm options.


Tank Shark® or PAX mixers transfer motive energy to the mass of water in the reservoir, placing it in motion and ensuring a fully mixed vessel. Mixers move colder dense water from the base of the reservoir up to and on top of the warmer stratified layers. In addition to removing temperature stratification which can hinder consistent disinfectant residual distribution, a fully mixed tank ensures accurate process feedback control in the dynamic environment of a water storage tank. Chemical injection occurs in the violent area of the nozzle discharge allowing for complete mixing and distribution of the applied chemicals.


If the disinfectant residual drops below a predetermined set point, chlorine and/or ammonia are injected into the upward flowing stream of water for dilution and mixing within the tank volume. Sophisticated dosing and analyzing algorithms assess the position of the homogeneous tank chemistry on the breakpoint curve and make the correct reagent dosing decisions. The Monoclor® RCS process is completely compatible with gas chlorine, bulk hypochlorite and on-site generated sodium hypochlorite. When chloramine delivery is a requirement, liquid ammonium sulphate (LAS) is the feedstock of choice.

A sample line is connected from the Tank Shark® mixer to a rotary gear pump located outside of the tank that is capable of drawing 10 GPH of representative water from the tank. The sample is then driven to a chlorine residual analyzer where a determination of water quality is made on a continuous basis.
