Lighting Solution for Wastewater Treatment Plants

Wastewater treatment plants are vital to public health and environmental protection, but in the treatment process, often accompanied by the production of hazardous gases, so we need to pay great attention to the selection of lamps for this kind of occasion.

Common Gases and Hazards

The wastewater treatment process generates several potentially dangerous gases:

• Methane (CH4): Highly flammable and explosive.
• Hydrogen Sulfide (H2S): Toxic and flammable.
• Chlorine (Cl2): Toxic and corrosive.

Other gases like sulfur dioxide, ammonia, ozone, and chlorine dioxide may also be present in certain plants.

Hazardous Area Classification

To ensure appropriate safety measures, wastewater plants are classified into hazardous zones based on the likelihood of explosive atmospheres. The most common classifications are:

• Class I, Division 1 or 2, Group D: For areas with methane gas.
• Class II, Division 1 or 2, Group G: For areas with combustible dust (less common).

Explosion Proof Lighting

Given the presence of flammable gases, it is crucial to use explosion-proof lighting to prevent fires and explosions. These lights are designed to contain potential ignition sources, making them safe for use in hazardous environments.

Consider using the Explosion-proof series product from AGC Lighting, as it can meet all the requirements for wastewater treatment plants.
