Chemical Dosing System for Cooling Towers
In industrial cooling tower systems, controlling water quality is a critical factor to ensure optimal cooling performance, extend equipment lifespan, and reduce operational costs. The automatic chemical dosing system provided by REECHEM offers a comprehensive and effective solution for water treatment in cooling towers.
1. System Components
The standard chemical dosing system for cooling towers includes:
-
Three chemical storage tanks:
-
Maxtreat 2500: Prevents scaling and corrosion in the cooling system.
-
Maxtreat 6910: Effectively eliminates microorganisms, algae, fungi, and biofilm.
-
Maxtreat CL5: Disperses microbial contaminants and inhibits metal corrosion.
-
-
Three dosing pumps: Each connected to a respective chemical tank to accurately inject the required chemical amount into the system.
-
Control panel: Configured with a timer and dosing parameters, ensuring consistent and automated operation based on real-time system conditions.
-
Online conductivity sensor: Monitors water quality in real time and triggers the automatic blowdown system to maintain conductivity within preset limits.
-
Valves, piping, and accessories: All integrated into the tower's circulation line.
-
Support frame: Holds the entire system securely and ensures easy maintenance access.
2. Operating Principle
The three chemicals—Maxtreat 2500, Maxtreat 6910, and Maxtreat CL5—are loaded into their respective tanks. Using precision dosing pumps, these chemicals are injected into the cooling tower pipeline system.
The dosing schedule is pre-calculated and configured using a timer by REECHEM's technical engineers based on:
-
Actual system conditions
-
Water quality control parameters
-
System circulation flow rate
The conductivity sensor continuously monitors water quality and sends real-time signals to trigger the automatic blowdown, ensuring the conductivity level remains within the optimal range.
3. Recommended Cooling Tower Chemicals
Below are some recommended chemical products designed specifically for cooling tower water treatment. These chemicals are highly effective in removing impurities and are widely endorsed by industry experts.
Maxtreat 2500
Key functions:
-
Prevents scale formation and corrosion
-
Deodorizes cooling water
-
Contains high-diffusion polymers and organic compounds that inhibit mineral deposition
This chemical is free from heavy metals such as zinc or chromates, making it safe and environmentally friendly.
Application: Dosed directly into the cooling tower using a metering pump or manually.
Maxtreat 6910
A best-selling chemical used to:
-
Control biological growth (algae, mold, bacteria)
-
Prevent microbial contamination and biofouling
Safety note: Avoid direct skin contact; store in a cool, dry place away from direct sunlight.
Maxtreat CL5
Specialized in:
-
Preventing the formation of slimy bacterial films
-
Inhibiting metabolic activity of harmful microorganisms
This chemical ensures high cleaning performance and is highly effective in biological control.
Safety note: Avoid skin contact; store in a dry environment for best preservation.
4. Safety Guidelines for Chemical Handling
To ensure effective water treatment and operator safety, follow these guidelines:
-
Choose chemicals that provide anti-scaling, anti-corrosion, and biocidal properties.
-
Consult specialists before combining chemicals to avoid dangerous reactions.
-
Always follow proper labor safety protocols:
-
Shut down the cooling tower
-
Display maintenance signs
-
Wear full protective equipment
-
-
Use chemicals in correct concentrations and as per instructions.
-
Monitor chemical circulation time to prevent corrosion of system components.
