Automatic Blowdown System for Cooling Towers – Smart Water Quality Control Solution

Why Do Cooling Towers Need Automatic Blowdown?

Blowdown (bleed-off) is the process of removing a portion of the circulating water to control the concentration of Total Dissolved Solids (TDS) and dissolved minerals. Cooling towers that are not blown down or are rarely blown down will cause several problems such as:

• Scaling (crust) accumulates in fillers, pipes, and heat exchangers → efficiency decreases.

• Corrosion increases → damaging metal components.

• Uncontrolled bacterial & algae growth → risk of Legionella.

• Water & chemical treatment costs increase due to waste.

Manual blowdown is inaccurate → can be too much (water waste) or too little (risk of scaling).

1. Automatic Blowdown System – An Automatic & Efficient Solution

Our device replaces manual blowdown with an automatic TDS & Timer-based system, providing:

✔ Water & energy savings (more controlled).

✔ Stable water quality (reduced risk of scaling & corrosion).

✔ More precise control (Two operating modes: TDS-based & Timer-based).

2 Operating Systems

1. TDS-Based Mode (Water Quality Control)

• Advanced TDS sensors monitor dissolved mineral concentration in real-time.

• Automatically opens the blowdown valve when TDS exceeds the set point.

• Advantages:
  

  • Only discharges water when necessary → Saves water & chemicals.

  • TDS concentration is always optimal → Prevents scaling & corrosion.

2. Timer-Based Mode (Time-Based Control)

• Blowdown runs according to schedule (e.g., 5 minutes every 2 hours).

• Suitable for applications with low or high TDS fluctuations.

• Advantages: Simple & reliable for all water conditions.
