Monoclor^®RCS  Residual Control System

The Monoclor® RCS system utilizes a powerful active mixer to rapidly blend disinfectant into the entire tank volume. The Monoclor® RCS system then samples the homogenized water and determines the appropriate chemical dosing strategy based on the disinfectant levels present in the reservoir. By dosing the right chemical at the right time into a completely mixed tank, the Monoclor® RCS system quickly reaches and maintains the desired residual set‐point.

PAX mixers transfer motive energy to the mass of water in the reservoir, placing it in motion and ensuring a fully homogeneous condition.

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 high energy mixing zone allowing for complete mixing and distribution of the applied chemicals.

If the disinfectant residual drops below a predetermined set point, chlorine only or ammonia is dosed into the reservoir. A Patented algorithm assesses the position of the homogeneous tank chemistry on the breakpoint curve and makes the correct 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.

The Chemlocker® system includes a sophisticated real‐time analytical tool that collects and transmits tank sample data (pH, total chlorine and ORP) to enable timely operator intervention – before an emergency occurs.  Once an operator decides that tank boosting is desired, the chemical reagents are introduced into the tank via a convenient venturi driven hose connection at the Chemlocker® panel.  Powerful tank mixing ensures that the chemical reagents are immediately mixed to start boosting the tank residual level.  

The Chemlocker® Reservoir Dosing Station provides operators and water quality professionals with a simple water quality management tool that can aid disinfectant residual management by providing both reservoir residual level assessment and chemical dosing of hypochlorite and or ammonia to reassert control to a free-chlorine or a chloramine disinfectant regime.

Total Chlorine Sampling and Analysis

• An integrated total chlorine analyzer provides dynamic tank residual analysis based on real-time sampling from the tank itself.
• Data availability for the overall network SCADA system.

Chemical Feed

• Simple eductor system for precise chemical injection of both ammonia (in the case of chloramine boosting) and hypochlorite (chlorine).
• A booster pump is optional where a high pressure water source is unavailable on-site.
• The analog flow information from the tank mixer is available locally at the Chemlocker® panel and also via SCADA for remote monitoring. This flow information provides vital feedback to the operator so as to preclude the possibility of chemical addition without proper simultaneous mixing and dispersion.

Smartboost Free Chlorine Boosting Systems utilize water storage assets as convenient and controllable intervention points for managing distribution network chlorine levels.

Similar to how the Monoclor® RCS chloramine management system maintains a constant disinfectant residual set-point in water tanks, Smartboost systems are used with distribution systems that utilize free chlorine residuals.
