The Top 5 Problems that Hypochlorite Skid-Mounted Chlorination Systems Solve

A self-contained hypochlorite skid-mounted chlorination system injecting sodium hypochlorite (NaOCl) can solve (at least) 5 major problems afflicting many small commercial, industrial or community water systems.

Hypochlorite Skid-Mounted Chlorination Systems,  or Hypo Skids, as the name implies, are skid-mounted automatic chlorination systems that monitor flow rate and chlorine residuals and inject hypochlorite (liquid chlorine bleach) at a precise dosage.

These systems are used to automatically maintain chlorine residuals in storage tanks, small distribution systems and in a multitude of commercial and industrial applications.

These are the problems solved by the Hypochlorite Skid-Mounted Chlorination Systems:

Problem #1:   Lack of chlorine residual in storage tanks

Water storage tanks that are not used regularly, or sit for long periods with little water being used, can develop dangerously low chlorine residuals.

The Hypo-Skid measures chlorine residuals inside the storage tank and the automatic circulation pump brings water from the storage tank through the skid.  If the chlorine residual drops below a preset low level, fresh chlorine solution is injected until residual is restored.

Problem #2:  Varying flow rates in the pipeline or distribution system make maintaining an accurate chlorine residual difficult.

Some small community and industrial applications have several water sources feeding into a central storage tank or facility.   The flow rates from different sources can vary, with the water flowing slower or faster through the piping.

The Hypo Skid easily solves this problem by sensing flow and chlorine residual and injecting chlorine proportionally, based on varying flow rates.   The result is an even and consistent chlorine residual.

Problem #3:  Small community systems or remote sites lack on-site staff that can operate and maintain a chlorination system and often end up with poor data collection and maintenance records.

Small community systems or remote commercial sites often lack trained operators , or they have operators but are not available to check on the water system daily.

The Hypo-Skid solves this problem because they are fully automatic and collect, store, and/or transmit   data automatically.  The on-board sensor and data-logger track free-chlorine residuals and allow operators easy access so they can see the chlorine residual levels over periods of time.

Internet and network access make it easy to monitor the system remotely by a web browser, or tie into an existing SCADA network.

Problem #4: Gas chlorination can be dangerous and costly to operate.

Selecting a NaOCl liquid chlorine bleach system over a gas chlorine system eliminates the danger of large-scale gas leaks from the high pressure tanks.  No special operators are required (in most states a Grade I or II operator can run a NaOCl system).   Gaseous chlorine has a low pH and it and lower the pH in drinking water.  Liquid bleach might increase the pH slightly or have no effect on pH, depending on dosages, generally there isn’t a significant change in pH using the NaOCl system.

Problem #5:  Chlorination systems often need to be deployed rapidly, with a minimum of installation and wiring done on site if possible, but many chlorination systems require extensive wiring and set-up.

More features of the chlorination system:

The Hypo-Skid chlorination systems install quickly and are up and running in little time compared to many commercial chlorination systems.   Electrical connections are prewired.  Connect piping to and from the storage tank and program unit and it begins to monitor and control chlorine residuals automatically.

Additional Features Include:

Hypo Skids can be used as in-line chlorination to inject directly into distribution systems.

Can be connected to a generator and used in emergencies where rapidly-deployed disinfection is required.

Use with liquid chlorine bleach, OR powdered calcium hypochlorite with water added.
