Successful Replacement of sodium Hypochlorite with
Ferrocid® 4555K
Background
The chlorine unit cooling tower at a major Saudi Arabian facility previously relied on sodium hypochlorite for microbial control. However, this method posed several challenges, including high corrosion risk due to aggressive oxidation, inconsistent microbial control, and persistent biofilm issues.
Additionally, the system required high chemical consumption (around 110,000 kg/year) and faced difficulties with storage and handling, such as decomposition and damage to dosing lines. These factors led to increased operational costs, inefficiencies, and safety concerns for plant personnel.
Objectives
- Improve microbial control and biofilm formation.
- Reduce corrosion and extend equipment life.
- Lower chemical consumption and simplify logistics.
- Enhance operational reliability and safety.
- Align with environmental compliance by reducing harmful byproducts.
