Municipal Water Treatment Solutions
Chemical feed, storage, and disinfection systems for municipal water utilities — material compatibility documented against sodium hypochlorite before equipment is specified, not after it fails.
Match the Chemistry Before You Match a Model
Sodium Hypochlorite Disinfection Feed
Sodium hypochlorite is the most common municipal disinfection chemical — and one of the most aggressive on the wrong valve or tank material. Material selection here is not optional.
Chemical Storage Tank Material & Containment
XLPE vs HDPE isn’t a preference question on a hypochlorite line — it’s a documented field-failure-timeline question. Get the resin and containment spec right before the tank ships.
Isolation Valves & Lockout/Tagout
A properly lockout-capable, correctly specified ball valve is what prevents a corroded, tagged-out valve from becoming a safety incident during service on a disinfection line.

Diaphragm pumps for backwash, sludge and chemical transfer
On a water treatment plant, one 3-inch air-operated diaphragm pump can cover sludge and backwash transfer and bulk chemical unloading. The FTI Air FT30P has polypropylene wetted parts, passes solids up to 0.50 in and moves up to 300 gpm at 120 psi air, with no seal to maintain.
Check the chemical first: FTI rates the housing excellent for ferric, alum, caustic and dilute acids but not for sodium hypochlorite (see the AODD chemical compatibility chart). Check the duty point and plant air with the diaphragm pump sizing calculator.
Frequently Asked Questions
What chemical is most commonly used for municipal water disinfection?
Sodium hypochlorite (NaOCl) is the most common municipal disinfection chemical. It is also one of the most aggressive chemicals on incorrectly specified valve seats, elastomers, and tank resins — material compatibility has to be confirmed before equipment is ordered, not after a failure.
Why does tank resin matter for sodium hypochlorite storage?
Standard HDPE tanks degrade faster in sustained sodium hypochlorite service than crosslinked polyethylene (XLPE) tanks. LibertyCES specifies XLPE as the standard for hypochlorite storage based on documented field-failure timelines, not just resin datasheets.
What valve feature matters most for a chemical disinfection feed line?
A true union body (service without cutting the line) and a built-in lockout/tagout point on the valve body itself — not a bolt-on accessory — are the two features that most directly affect both downtime and operator safety on a hypochlorite line.
Does LibertyCES supply full disinfection feed systems, or individual components?
Both. LibertyCES specifies complete chemical feed systems — tank, metering pump, valves, and monitoring — for municipal utilities, and also supplies individual replacement components matched to an existing system’s exact specification.
Specifying a disinfection feed system?
Send LibertyCES the chemical, concentration, tank size, and current equipment — we'll confirm the material spec before anything ships.
