Biological Audit

Service Description: The ABS Biological Audit is a survey, which evaluates the health of the biomass in the secondary wastewater treatment system.

Features: ABS carries out both microscopic and microbiological analysis at each trophic level including, rotifera, protozoa, algal, bacterial and fungal. The ABS Biological Audit identifies problems caused by biomass which result in:

High effluent BOD

High effluent TSS

Poor settleability and low RAS concentrations

Excessive polymer operating costs

Benefits: The information from the Audit can be used to improve process efficiency and reduce operating expenditure. The ABSWastewater System Audit has many benefits including:

1) Minimizing operating costs.

2) Optimizing process efficiency.

3) Defining operational short-comings.

4) Eliminating biomass settleability problems.
