Temperature in the wastewater industry affects biological and chemical processes essential for water treatment.

Wastewater

Tel-Tru temperature sensing and monitoring instruments offer reliable solutions to ensure these processes operate within optimal temperature ranges, enhancing the efficiency and effectiveness of water and wastewater treatment facilities.

Temperature significantly influences the activity of bacteria in wastewater treatment systems. These bacteria thrive within a specific temperature range, typically between 68° and 95°F (20°–35°C). At lower temperatures, bacteria may slow down and at higher temperatures bacteria can become ineffective or cease to function, leading to system upsets. These upsets are characterized by deflocculation, where bacterial floc breaks apart, resulting in higher levels of total suspended solids (TSS) in the effluent.

Wastewater Temperature Control Applications At-a-Glace

Critical Monitoring: Temperature monitoring and control in water and wastewater treatment for managing bacterial activity and overall process efficiency.

Preventing Upsets: Proper temperature monitoring helps prevent bacterial stress and ensures effective treatment processes.

Industrial Design for Harsh Environments: Tel-Tru provides a range of temperature monitoring instruments, including RTDs, digital thermometers, and monitoring systems, to meet the diverse needs and environments in the water and wastewater industry.

Regulatory Compliance: Our accurate and reliable temperature monitoring ensures compliance with environmental regulations, preventing fines and penalties.

Major Signs of High Temperature-Related Bacterial Stress

  1. Deflocculation and High Effluent TSS: Elevated temperatures cause bacterial floc quality to deteriorate. This leads to higher TSS levels, indicating poor water quality and treatment issues.
  2. Reduced Bacterial Activity: At high temperatures, the efficiency of bacteria in breaking down organic matter decreases significantly, disrupting the wastewater treatment process.

Accurate temperature monitoring is crucial because temperature changes impact other measurable parameters such as pH, conductivity, and dissolved oxygen. These changes affect water density, the ability to support aquatic life, and the capacity to absorb gases and nutrients. Higher temperatures can increase the solubility of certain chemicals and promote the growth of algae blooms, which consume oxygen and harm aquatic ecosystems.
