W2 Systems wastewater neutralization systems are designed to treat influent wastewater with pH from 0.1 to 13.99 pH units. Standard neutralization systems can treat up to 90 GPM with 48 minutes of retention. W2 has over twenty neutralization system installations including at:

Our large range of multi-compartment neutralization systems treat influent streams with wide flow and pH variations.

Standard WN package neutralization systems have simplex, duplex and triplex compartments-

B1 Series - Batch/Simplex Flow, up to 600 gallons retention volume
F2 Series - Duplex Flow, up to 4400 gallons retention volume
F3 Series - Triplex Flow, up to 4700 gallons retention volume

With Acid and Caustic Feed Tank/Pumps systems sized to treat all influent wastewater conditions.

Indicators and Controls

• Pump Hand/Off/Auto switches and running lights
• pH Analyzer in each compartment

• Compartment level control/alarms -
  • Low-low level switch pump shutoff
  • Start pH adjust level switch
  • High level local alarm
• Containment switch activates local alarm
• 2 Acid/Caustic control/alarm levels -
  • Low level switch local alarm
  • Containment switch local alarm
• Optional dry contacts for remote monitoring
  • Effluent pH out-of-spec alarm
  • Acid or Caustic low level alarm
  • Containment level alarm

Control System and Power Supply

The control system monitors the solution pH in each compartment and actuates and controls the caustic or acid feed systems. Course and/or fine feed depends on how far the batch pH is from the setpoint value.

The effluent pH is indicated and recorded, and local alarms are actuated if the pH falls outside the setpoint limits.

• UL-listed NEMA 4X enclosure
• Motor starters with thermal overload relays
• 110 VAC, 208 VAC or 240 VAC 3-phase
• PLC can be field- programmed via RS232 port
• All power and controls pre-wired with FAT
• Main safety disconnect switch by others
