System Performance Specifications:

The pHASE family of pH Adjustment Systems are small, compact, packaged pH neutralization systems designed to neutralize acidic and alkaline wastewater discharges from any source.

The pH system displayed here is an example of our pHASE family of pH systems and is capable of treating wastewater flows of up to 10 GPM continuous and 20 GPM intermittent. With the use of an influent equalization system, which is standard on all of our pH systems, periodic flows in excess of 50 GPM can be handled.

The pHASE family of pH systems are well suited to neutralize wastewater streams from any source including highly acidic or highly alkaline effluent streams.
Influent Characteristic: Flow 0-20 GPM, 10 GPM average / 600 GPH max. Influent pH: 0 < pH < 14. Temperature 32-140F. (High temp units available for temperatures up to 212F.

Effluent pH Range: typical 6.5 < pH < 8.5 (note: the effluent pH range is fully programmable through the operator interface).

Effluent Monitoring: As mandated by the local controlling authority and by most discharge permits continuous monitoring of effluent flow and pH is provided on a circular chart recorder, paperless recorder, or via a data logger. Additionally SCADA systems are available with automatic report generation.

Controls: All of our pH Adjustment Systems are fully automated with PLC based controls (typically Allen-Bradley) with no operator intervention required.

Utilities, Weights, Dimensions:

All of our pH neutralization systems are supplied as complete "turnkey" packages. Prior to shipping all piping and electrical connections are complete and the pH system undergoes extensive burn in testing in our QC area including a wet / hydro test.

The Main Control Panel (MCP) is equipped with an optional main disconnect providing OSHA Lock Out / Tag Out (LOTO) and UL 508 compliance. Electrical requires a single point connection.

All of our pH adjustment systems utilize a fail safe valve on the discharge that immediately halts flow in the event of a discharge contravention, alarm, or a loss of power. This valve requires a small air supply. If air is not available the same function is provided in an all electric configuration.

480VAC, 3 phase, 60 Hz, 15 amp. Disconnect not required (a disconnect is provided on our MCP).

Air: Less than 1 SCFH @ 80 psig.

Dimensions: 48" x 120" x 120"(H) - Including the optional influent equalization system.

Weight: Approx. 850 lbs. dry (not including shipping crate).


All systems are built to the applicable standards: ASTM, ASME, ANSI, NEC NFPA 70 & NFPA 79, UL 508A, etc.

All systems undergo an extensive documented Factory Acceptance Test (FAT) with GAMP validation available.
Tanks: PP, PE, XLPE, FRP, and all stainless alloys.

Pipe, Valves, and Fittings: PVC, CPVC, PP, PE, PVDF, and all stainless alloys.

Main Control Panel: All of our pH systems are controlled by an programmable logic controller (PLC) typically Allen-Bradley. All panels are built to NEC, UL 508 and OSHA standards.
