Description
What Is a Chemical Dilution System?
A chemical dilution system is a packaged process system designed to combine a concentrated chemical with a controlled quantity of dilution fluid, typically water, to produce a solution at the required concentration.
Depending on the application, the system can incorporate:
- Chemical feed pumps
- Dilution water supply
- Chemical storage or feed tanks
- Mixing systems
- Metering equipment
- Flow measurement
- Level instrumentation
- Pressure instrumentation
- Control valves
- Isolation valves
- Check valves
- Piping and fittings
- Chemical injection points
- PLC-based controls
- Touch-screen HMI
- Safety interlocks
The final arrangement is selected according to the chemical, required concentration, flow rate and process requirements.
Chemical Dilution Skid Applications
Aegis Projects can engineer dilution systems for a range of chemical treatment and process applications, including:
- Disinfection systems
- Fluoride treatment
- Sodium hypochlorite systems
- Potassium permanganate dosing systems
- Sodium hydroxide feed systems
- Sulfuric acid dosing
- Sodium bisulfite metering
- Dispersant polymer dosing
- Alum feed
- Coagulation and flocculation
- Hydrochloric acid metering
The system configuration can be customized depending on the chemical properties and the required dilution and dosing process.
Chemical Dilution Process
A typical chemical dilution system can operate through a controlled sequence:
Concentrated Chemical → Chemical Metering → Dilution Fluid Addition → Controlled Mixing → Diluted Chemical Solution → Process Feed
The dilution ratio and operating sequence are established according to the project requirements.
Automation can be incorporated to control chemical and dilution-fluid flow, monitor tank levels and maintain the required operating sequence.
Chemical-Compatible Materials
Material selection is an important consideration when designing a chemical dilution skid.
Depending on the chemical and operating conditions, systems can be constructed using materials such as:
- PVC
- CPVC
- Stainless steel
- Alloy 20
- Other suitable chemical-compatible materials
Material selection should consider:
- Chemical composition
- Chemical concentration
- Dilution ratio
- Operating temperature
- Operating pressure
- Corrosion characteristics
- Compatibility with wetted components
Pump components, piping, valves, tanks, seals, fittings and instrumentation should be evaluated for compatibility with the specific chemical service.
Automated Chemical Dilution Systems
Aegis Projects can integrate PLC and HMI-based automation into chemical dilution skids.
Automation functions may include:
- Chemical feed control
- Dilution water control
- Automatic mixing sequences
- Flow monitoring
- Tank level monitoring
- Pump start/stop
- Valve sequencing
- High and low-level alarms
- Process interlocks
- Chemical feed monitoring
- Emergency shutdown
- Alarm indication
- Local HMI operation
- Remote monitoring or control where required
Automated operation can reduce manual intervention and provide a more consistent dilution process.
Skid-Mounted Chemical Dilution Packages
Aegis Projects can integrate the complete dilution process onto a common structural skid.
A typical package can combine:
Chemical Feed System + Dilution System + Mixing + Piping + Instrumentation + Automation
This provides a compact and organized solution that can be assembled and tested before shipment to the project site.

Chemical Dilution for Water & Wastewater Treatment
Chemical dilution systems can be incorporated into water and wastewater treatment facilities where concentrated chemicals need to be prepared at a suitable process concentration.
Potential applications include:
- Disinfection
- pH adjustment
- Coagulation
- Flocculation
- Water conditioning
- Chemical treatment
- Process-water treatment
The dilution and feed system can be designed according to the required treatment process and chemical characteristics.
Custom Chemical Dilution System Engineering
Each chemical dilution application has its own requirements. Aegis Projects can develop customized systems based on:
- Chemical type
- Chemical concentration
- Required final concentration
- Required dilution ratio
- Chemical feed rate
- Dilution-fluid flow

- Mixing requirements
- Operating pressure
- Operating temperature
- Materials of construction
- Instrumentation
- Automation requirements
- Installation space
- Site conditions
The system can be supplied as a standalone dilution package or integrated with a larger chemical feed, metering or treatment system.

Safety & Chemical Handling
Chemical dilution systems must be engineered according to the properties and hazards of the chemicals being handled.
For corrosive, toxic, hazardous or reactive chemicals, appropriate provisions may include:
- Chemical-compatible materials
- Secondary containment
- Leak detection
- Pressure relief
- Isolation valves
- Emergency shutdown
- Appropriate ventilation
