The electrochlorination<\/strong> system is a highly effective solution for preventing marine fouling in seawater intakes, piping, and heat exchangers<\/strong> aboard vessels and offshore units. Based on a process that involves the electrolysis of seawater<\/strong>, the system generates active chlorine compounds that inhibit the growth of biological organisms along internal saltwater lines. <\/p>

How the process works<\/strong><\/p>

Seawater is drawn directly from the discharge of a standard pump or a pump dedicated to the MGPS system and fed into a generator chamber (electrolyzer)<\/strong>. In this chamber, using specially designed titanium electrodes, the saltwater undergoes electrolysis, resulting in the formation of active chlorine<\/strong> (primarily sodium hypochlorite). <\/p>

This agent is then injected at strategic points in the system, such as seawater intakes and filters<\/strong>, where it mixes with the incoming water and protects internal surfaces against the growth of marine organisms such as barnacles, mussels, and algae.<\/p>

Major chemical reactions<\/strong><\/p>

  1. Formation of Chlorine (at the anode):<\/strong> 2Cl\u207b \u2192 Cl\u2082 + 2e\u207b<\/li>
  2. Hydroxide Formation (at the cathode):<\/strong> 2H\u2082O + 2e\u207b \u2192 2OH\u207b + H\u2082<\/li>
  3. Hypochlorite Production:<\/strong> 2NaOH + Cl\u2082 \u2192 NaOCl + NaCl + H\u2082O<\/li><\/ol>

    Sodium hypochlorite (NaOCl)<\/strong> solution acts as a powerful oxidizing agent, preventing the attachment of fouling organisms and eliminating microorganisms present in the water.<\/p>
