A new algorithm standardizes biostability curves to predict and control bacterial regrowth in drinking water. This method helps water utilities manage disinfectant residual and substrate levels for improved water quality.

Area of Science:

Environmental Science
Microbiology
Water Treatment

Background:

Biological stability in drinking water is crucial for limiting microbial regrowth.
It depends on disinfectant residual concentration and microbial growth substrate availability.
Bacterial regrowth in distribution systems is influenced by disinfectant inactivation and substrate-driven growth.

Purpose of the Study:

To present a standardized algorithm for generating biostability curves.
To enable water utilities to apply biostability curves for site-specific needs.
To assess the algorithm's applicability in controlling bacterial regrowth.

Main Methods:

Development of a standardized algorithm for biostability curve generation.
Application of pilot-scale studies using the algorithm.

Main Results:

The algorithm successfully generated biostability curves.
The approach was effective in controlling HPC regrowth in chlorinated systems with Assimilable Organic Carbon (AOC) as the limiting substrate.
The algorithm controlled AOB regrowth in chloraminated systems where ammonia was the limiting substrate.

Conclusions:

The standardized algorithm provides a practical tool for water utilities to assess and manage biological stability.
Biostability curves are a valuable graphical approach for understanding and mitigating bacterial regrowth in drinking water distribution systems.
The algorithm is applicable to different disinfection strategies and limiting substrates.
