1. PROCESS DESCRIPTION

1.1. Sump Tank (T-SUMP)

1.1.1. Industrial wastewater enters the Sump Tank (T-SUMP). The submersible mixer (M-SUMP) continuously stirs the Sump contents to create a homogenous mixture. Transfer Pumps P1-SUMP and P2-SUMP pump the wastewater from the Sump to the ProDELTA-Plus pH Adjustment System based on tank level and operational status of the downstream equipment.

1.2. ProDELTA-Plus 200-GPM pH Adjustment System

1.2.1. Industrial wastewater enters the first Reaction Tank (RT-1) from which the wastewater gravity flows to the second Reaction Tank (RT-2). Each Reaction Tank is equipped with a mixer (agitator) that continuously stirs the wastewater to maintain a homogenous environment within each Reaction Tank. Two (2) pH Probes are installed in each Reaction Tank. The PLC-based control system automatically adjusts the pH within the Reaction Tanks using acid and/or caustic based on the pH readings from the pH Probes. After the wastewater is neutralized in the Reaction Tanks it gravity flows to the Monitoring Pipe Spool (MPS). If the pH in the Monitoring Pipe Spool is within dischargeable limits the wastewater is discharged to the sewer. If the pH is out of range, the wastewater is returned to the Sump for additional treatment.

2. EQUIPMENT DESCRIPTION (SUMP)

2.1. Transfer Pumps (P1-SUMP, P2-SUMP)

2.1.1. Transfer Pumps P1-SUMP and P2-SUMP are submersible pumps that transfer wastewater from the Sump to the ProDELTA-Plus pH Adjustment System. The pumps operate in an alternating lead/lag operation.

2.1.2. Transfer Pumps P1-SUMP and P2-SUMP are each rated for 200 GPM @ 35’ TDH. The transfer pumps operate using VFDs (VFD-1, VFD-2) which regulate the speed of the motor to maintain a user-adjustable speed based on the liquid level in the sump.

2.1.3. The PLC-Based Control System automatically alternates between the two transfer pumps (P1-SUMP or P2-SUMP) as the lead pump for each pumping cycle. The Control System will automatically start and stop the lead pump based on the liquid level in the Sump Tank (T-SUMP) measured by the Level Transmitter (LT-SUMP), whenever the Hand-Off-Auto (HOA) switch for each pump is set to AUTO. The operator may also select the lead pump manually.

2.1.4. When the pump HOA switch is set to HAND, the pump will operate regardless of the level measured in the tank. If the pump is left ON, it may run dry, causing damage to the pump.

2.2. Mixer (M-SUMP)

2.2.1. Mixer (M-SUMP) is used to continuously stir the wastewater to maintain a homogenous environment within the Sump Tank. The mixer operates automatically when the Process Switch is ON.



2.3. Level Transmitter (LT-SUMP)

2.3.1. The liquid level in the Sump Tank (T-SUMP) is monitored by a pressure-based Level Transmitter (LT-SUMP) with the following user-adjustable set-points:

The Low-Low-1 (LL1) level set-point disables the mixer when the set-point is dry.

The Low-Low-2 (LL2) set-point enables the mixer when the set-point is wet.

The Low-Low (LL) set-point disables both transfer pumps when the set-point is dry.

The Low-1 (L1) level set-point enables the lead transfer pump at the user-adjustable low speed when the set-point is wet.

The Low-2 (L2) level set-point enables the lead transfer pump at the user-adjustable medium speed when the set-point is wet.

The Low-3 (L3) level set-point enables the lead transfer pump at the user-adjustable high speed when the set-point is wet.

The High (H) level set-point enables both transfer pumps at 100% speed when the set-point is wet.

The High-High (HH) level set-point activates an auditory and visual alarm to warn that the tank may overflow and disables the influent permissive signal.

2.4. High-High Level Switch (LSHH-SUMP)

2.4.1. The liquid level in the Sump Tank (T-SUMP) is monitored by a redundant High-High level switch that acts as a backup to the Level Transmitter. When wet, the switch enables both transfer pumps (P1-SUMP, P2-SUMP) at 100% speed, activates an auditory and visual alarm to warn that the tank may overflow and disables the influent permissive signal.

2.5. Low-Low Level Switch (LSLL-SUMP)

2.5.1. The liquid level in the SUMP Tank (T-SUMP) is monitored by a redundant Low-Low level switch that acts as a backup to the Level Transmitter. When dry, the switch disables the sump mixer (M-SUMP) and the submersible transfer pumps (P1-SUMP, P2-SUMP).

3. EQUIPMENT DESCRIPTION (PH ADJUSTMENT SYSTEM)

3.1. Reaction Tanks (RT-1, RT-2)

3.1.1. The Reaction Tanks (RT-1, RT-2) each have a capacity of 1900 gallons and are fabricated from fiberglass.

3.2. Mixers (M-RT1, M-RT2)

3.2.1. Mixers M-RT1 and M-RT2 are used to continuously stir the wastewater to maintain a homogenous environment within the Reaction Tanks. The mixers operate automatically when the Process Switch is ON.

3.2.2. Chemical addition is disabled in a reaction tank if the mixer HOA is placed in HAND/OFF mode or if a motor fault occurs.



3.3. pH Probes (AE1-RT1, AE2-RT1, AE1-RT2, AE2-RT2)

3.3.1. pH Probes AE1-RT1, AE2-RT1, AE1-RT2 and AE2-RT2 measure the pH of the solution in the Reaction Tanks (RT-1, RT-2). Transmitters AT-1, AT-2, AT-3, and AT-4 receive signals from the pH Probes.

3.3.2. The PLC-based control system starts and stops the chemical metering pumps as needed to adjust the measured pH in each Reaction Tank. The Control System adjusts the rate of delivery of the chemical metering pumps, depending on the deviation from the target set-point (i.e. the metering pump operates at a reduced delivery rate for a small deviation and at an increased delivery rate for a large deviation). Chemical addition is disabled in a Reaction Tank in case of a pH transmitter or mixer fault.

3.3.3. The pH control set-points are user-adjustable for each Reaction Tank. The system will adjust the gains of the pH loops based on the flow rate through the system. The factory settings are noted below. These may be changed after system commissioning to adjust to actual operating conditions.

3.3.4. Reaction Tank RT-1 settings:

CP-1 operates when pH < 6.25

AP-1 operates when pH > 8.75

3.3.5. Reaction Tank RT-2 settings:

CP-2 operates when pH < 6.25

AP-2 operates when pH > 8.75

3.3.6. In each reaction tank, one pH Probe will be online (user-defined) and control pH adjustment and alarms. The other will be on stand-by and serve as a deviation monitor for the online pH Probe. If the pH measurements from the two probes drift apart by a user-defined value an alarm will be activated. If the measurements drift apart beyond a second user-adjustable value, chemical addition to the corresponding Reaction Tank will be disabled. In the event that the online pH Probe experiences a fault condition, the stand-by pH Probe will automatically assume online status.

3.4. Control Valves (AFV1-MPS, AFV2-MPS)

3.4.1. Control Valves AFV1-MPS and AFV2-MPS are pneumatically actuated two-way valves that direct the flow of wastewater to the sewer and to the Sump for additional treatment. When the pH of the wastewater inside the Monitoring Pipe Spool (MPS) is within dischargeable limits the valves are energized and open to the sewer. When the pH of the wastewater is outside dischargeable limits, the valves are then de-energized and open to the Sump for additional treatment.

3.5. Discharge pH Probes (AE1-MPS, AE2-MPS)

3.5.1. pH Probes AE1-MPS and AE2-MPS measure the pH of the wastewater in the monitoring pipe spool installed on the discharge piping of the system. Transmitters AT-5 and AT-6 receive signals from the pH probes.

3.5.2. In the monitoring pipe spool, one pH Probe will be online (user-defined) and control pH related alarms and system responses. The other will be on stand-by and serve as a deviation monitor for the online pH Probe. If the pH



measurements from the two probes drift apart by a user-defined value an alarm will be activated. If the measurements drift apart beyond a second user-adjustable value the system will disable discharge to the sewer. In the event that the online pH Probe experiences a fault condition, the stand-by pH Probe will automatically assume online status.

3.6. Air Compressor (CDA-1)

3.6.1. Air Compressor CDA-1 supplies clean dry air to Pumps P1-CAUSTIC and P1-ACID and pneumatic control valves AFV1-MPS and AFV2-MPS.

3.7. Pressure Switch (PS-1)

3.7.1. A Pressure Switch (PS-1) is installed on the CDA supply line to confirm CDA pressure is available to the system. If low pressure is detected by the Pressure Switch an auditory and visual alarm is activated.

3.8. High-High Level Switch (LSHH-RT1)

3.8.1. The liquid level in the first Reaction Tank (RT-1) is monitored by a single-point level switch. When wet, the switch activates an auditory and visual alarm to warn that the tank may overflow and disables the Sump Transfer Pumps.

3.9. Flowmeter (FE/FT-MPS)

3.9.1. Flowmeter FE-MPS is a magnetic flowmeter that measures the flow rate of wastewater discharged from the system. The system uses the position switch feedback from the control valves on the discharge to monitor whether the system effluent is discharged to the sewer or recirculated to the sump for additional treatment. Both the total flow to the sump and the total flow to the sewer are data-logged via the HMI’s integral Data Logger.
