How It Works: pH
Neutralization System
Step 1 The waste stream enters the pH
Neutralization Tank first. Chemicals are added to this tank to adjust the pH
between 8 and 9.
Step 2 The pH adjusted waste stream
is pumped into the Flocculator where polymer is added.
Step 3 The treated, clarified waste
water (effluent) is discharged through the vertical gray pipe with sight
glass, and the metal
hydroxides settle to the bottom of the Inclined Plate Settler.
Step 4 Sludge is pumped to the Sludge
Thickener Tank.
Step 5 In this dewatering phase, the
Filter Press compresses the sludge into a cake.
The process operates itself. Once hooked up to the process tank and
programmed for your application, the unit monitors the bath chemistry while
continuously filtering the suspended solids from the solution. The PLC
computes the bath needs and doses the appropriate chemicals to satisfy the
demand. The screen provides continuous information about the operation of
the system and the condition of the solution. The system notifies the
operator of any abnormal conditions.
The system is designed to meet pH, heavy metals, solids, and other
discharge limits. The system is shipped as modular components for assembly
at the plant.
