Hydraulic Retention

Time Study

Service Description: The ABS Hydraulic Residence Time (HRT) Study is designed to identify short-circuiting in a wastewater treatment system, which can result in reduced operating efficiency, treatment capacity and potential NPDES permit violations.

FeaturesUnlike other companies, ABS has the experience and ability to successfully apply dye, metal and biological tracers for HRT studies.

The ABS Hydraulic Residence Time Study includes:

• Selection of the most applicable tracer

• Ability to apply dye, metal and/or biological tracers

• Innovative methods of identifying short-circuiting

• A cost-effective approach

• Solutions to hydraulic short-circuiting problems

Benefits The HRT Study can result in improving removal efficiencies, capacity and avoiding potential NPDES permit violations. The ABS Hydraulic Residence Time Study has many benefits:

1) Economical biological tracer options.

2) Identifies short-circuiting.

3) Provides solutions to short-circuiting.
