WATER CONSERVATION

THROUGH DIGESTER HE CONDENSATE RECOVERY IN SOUTH AFRICA

In the journey towards sustainable water usage, every drop counts. With this ethos, Anssum embarked on an initiative in South Africa centered around the Digester Heat Exchanger (HE) Condensate Recovery system. This article delves into the project’s objectives, the measures employed, and the commendable outcomes achieved.

Project Overview

  • Focus Area: Water Conservation
  • Country: South Africa
  • Description: Digester HE Condensate Recovery
  • Status: Completed
  • Timeline: July 28, 2022 – August 23, 2022

The Objective

The primary goal was clear: optimise the Digester HE system to enhance condensate recovery rates. However, this broad objective was broken down into specific actionable measures, ensuring a structured approach to achieving the desired results.

The Anssum Strategy

To realise the project’s objectives, Anssum implemented the following measures:

  • Counter-Current Configuration: Ensured that the HE configuration was counter-current across all digesters. This configuration is known to enhance heat exchange efficiency, crucial for optimal condensate recovery.
  • Operational Excellence: Ensured the flawless operation of the sample coolers. These coolers play a pivotal role in maintaining system efficiency and ensuring condensate recovery.
  • Sensor Calibration: Undertook precise calibration of the conductivity sensors and the condensate collection tank level sensors. Accurate sensor readings are crucial for monitoring and optimising system performance.
  • Parallel Ball Valve Installation: Addressed the sample cooler challenges by installing a parallel ball valve. This strategic addition mitigated issues previously faced, enhancing system reliability.

Outcomes

Anssum’s meticulous approach yielded noteworthy results:

  • Condensate Recovery Boost: Achieved an impressive 10% improvement in condensate recovery rates.
  • Sensor Longevity: Process changes were implemented ensuring that the conductivity sensor replacements were not affected, thereby increasing their operational lifespan.

In Conclusion

The Digester HE Condensate Recovery project exemplifies Anssum’s dedication to efficient water usage and conservation. Through detailed planning, technical expertise, and a commitment to excellence, Anssum continues to lead the way in water conservation efforts, ensuring a more sustainable future.
