Chemical Feed Systems
Chemical feed systems play an important role in water treatment, wastewater treatment and industrial processes where chemicals must be introduced accurately and consistently. From pH adjustment and disinfection to corrosion control and polymer feed, a properly designed chemical feed system helps maintain process control while improving reliability and efficiency.
At CEJCO, we provide solutions designed around the requirements of each application. By combining metering pumps, chemical storage tanks, controls, piping and other system components, chemical feed equipment can be configured as an integrated system rather than a collection of individual components.
What Is a Chemical Feed System?
A chemical feed system stores, meters and delivers a controlled amount of chemical into a process. The exact design depends on the chemical being handled, required flow rate, operating pressure and level of automation needed.
A complete chemical dosing system may include:
- Chemical metering pumps
- Chemical storage or day tanks
- Piping, valves and fittings
- Flow measurement and monitoring equipment
- Control panels and instrumentation
- Containment and safety components
- Skid-mounted equipment and fabricated assemblies
Selecting compatible components is especially important when handling corrosive or aggressive chemicals. Pump materials, piping, seals, tanks and accessories should all be evaluated for the specific chemical and operating conditions.
Chemical Metering Pumps
The metering pump is at the heart of many fabricated skids. These pumps are designed to deliver precise, repeatable quantities of chemical into a process.
Depending on the application, chemical metering pumps can provide manual or automated flow adjustment and integrate with process controls to vary chemical dosage based on changing conditions.
CEJCO represents chemical metering and dosing equipment for a wide range of flow rates, pressures and chemicals, allowing the pump to be selected around the application rather than forcing the process around a standard solution.
Common Chemical Feed System Applications
Chemical feed and dosing systems are used throughout municipal and industrial facilities for applications including:
- Water and wastewater treatment
- pH adjustment and control
- Chlorination and disinfection
- Polymer feed
- Corrosion and scale control
- Chemical neutralization
- Cooling water treatment
- Boiler water treatment
- General process chemical dosing
Each application requires accurate and consistent chemical delivery to help maintain proper treatment levels, process performance and reliable operation.
Skid-Mounted Chemical Feed Systems
For applications requiring multiple components, a skid-mounted unit can provide a compact and organized solution.
Pumps, piping, valves, instrumentation and controls can be assembled onto a common skid, reducing the amount of field assembly required and providing a system designed to work together.
CEJCO’s in-house fabrication and controls capabilities allow us to support chemical feed projects beyond individual equipment selection. Systems can be engineered and fabricated around the process requirements, available space and control needs of the facility.
Chemical Storage and Handling
Reliable chemical dosing begins with proper chemical storage. Tank material, capacity, containment and connections should be selected based on the chemical and application.
CEJCO offers chemical storage solutions including Poly Processing tanks for demanding chemical applications. These systems can be paired with pumps, controls and other equipment to create a more complete chemical storage and feed solution.
Controls and Automation
Modern chemical feed systems can incorporate controls that help operators maintain consistent dosing and monitor system performance.
Depending on the application, controls may integrate signals from flow meters, level sensors and other process instrumentation. Automated chemical dosing can then adjust pump output as process conditions change.
With in-house controls capabilities, CEJCO can help integrate chemical feed equipment with control panels and instrumentation for a more complete system approach.
Building the Right Chemical Feed System
There is no single chemical feed system that works for every application. Chemical compatibility, required dosing rate, pressure, storage capacity, redundancy, controls and installation environment should all be considered during system design.
CEJCO works with municipal and industrial customers to select, engineer and integrate chemical feed equipment for their specific processes. From an individual metering pump to a complete fabricated chemical feed skid, our team can help develop a solution built around the application.
