Overview

• Learn about seven of the essential wastewater system components, including tanks, pumps, sensors, and the human operators themselves

• Get information to help determine if your current equipment is working as intended, if it’s stretched beyond its limits, or if it’s overkill

• Find out if your alarm conditions, component failures, and chemical usage are typical or if they are signs of bigger problems

• Receive tips to improve overall operational efficiency and reliability of your wastewater systems

Wastewater Treatment System

Poll Question

What aspect of your wastewater system do you struggle with the

Talking Points for Each Component

• What is it?

• Why does it matter?

• What can go wrong? What should we look for?

Types of Tanks

• Cylindrical

• Rectangular

• Flat bottom

• Conical bottom

• Baffled

Tank Materials of Construction

Plastic

Fiberglass

MetalImage: Burt Process

Tanks: Why Do They Matter?

• Mixing

• Measuring

• Transferring materials

Tanks: What Can Go Wrong?

Unusual Odor

Damage or Structural Failure

Sensors

• Measure parameters

• Provide data

• Examples of parameters to measure:

- Level

- Flow

- Conductivity

- ChlorineImage: Burt ProcessImage: Walchem

Sensors: Why Do They Matter?

Inputs and Outputs

Periodic Maintenance

Sensors: What Can Go Wrong?

Dirty/Fouled

Failure (slow and rapid)

History and trending

Sensors: Maintenance Considerations

Cleaning

Calibration / Verification

Required Supplies

Spares

Control System

• Combination devices

• Power on/off motors

• Activate/deactivate switches

• Hard-coded “brain”

Control System: Why Does It Matter?

It controls everything (or just about) that happens in the process

Control System: What Can Go Wrong?

• Wire connections

• Power surges/fluctuations

• Clicking, chattering

• Sparking/arcing

• Fault lights/horns

• Periodic testingImage: Burt Process

Control System vs. Controller

• What does a controller do?- Supplies powers sensors

- Receives signals from sensors

- Often transmits signals to another device

Controllers

Single-parameter

Multi-parameter

Transfer material from one place to another, often

through a process.

Pumps: Why Do They Matter?

• Affect changes

• Process parameters

• Accurate measurement

Types of Pumps

• Centrifugal

• Self-priming

• Progressing cavity

• Diaphragm

• Submersible

• Metering

• PeristalticImage: Burt Process

Failure

Performance deterioration

Mixers & Agitators

Goal is to keep material (liquid) homogeneous through continuous motion.

Mixers & Agitators: Why Do They Matter?

• Homogenous solution

• Representative reading

• Sensor position

• Solids/Floc

Poll Question

Which of these best

describes your

wastewater

system?

Filters

Types of Filters

• Screens

• Strainers

• Particulate

• Ion exchange resin

• Activated carbon

Operators

• Uptime

• Scheduling

• Collecting & using data

• Regulatory reporting

Operators: Why Do They Matter?

• The human brain

• Make decisions based on inputs

• Can predict an outcome before it happens

• Respond to malfunctions

• Ensure supply of spares

Operators: What Can Go Wrong?

• People first

• Listen to them

• Ask questions

• Share information

How It All Works Together

Summary

• Overview of major components of most wastewater treatment processes

• General purpose of each component

• Common symptoms and the potential problems that they indicate

• How you can tune-in to the system to identify problems early

• Coming together to work together to reach a common goal or output:
