Wastewater Treatment Works Flow to Full Treatment - Monitoring and Compliance Assessment Method Development

Many Wastewater Treatment Works (WwTW) have MCERTS flow monitoring equipment at the works outlet only, which poses difficulties for assessing compliance with discharge permit conditions for Flow to Full Treatment (FFT).

We investigated the range of measurement arrangements currently in use, and their implications for FFT compliance assessment. Water companies and Regulators were consulted on their views regarding the potential (and need) for alternative FFT compliance assessment methods.

Two alternative methods (driven by flow and EDM data) were developed and applied. Approach 1 involved comparing durations of storm weir spill events and durations for which associated effluent flows exceed a FFT consent threshold. Approach 2 involved determining the level at which effluent flow reaches a plateau during storm weir spill events.

The feasibility of using static flow surveys to determine FFT compliance is also discussed.

Extending and Updating UKWIR's Pollution Source Apportionment Tool (2)

The SAGIS-SIMCAT modelling system underpins a significant part of the Water Industry’s water quality investment planning through providing the ability to develop effective evidence-based Programmes of Measures whilst maintaining the ‘Polluter Pays Principle’. SAGIS-SIMCAT will serve as the regulatory agencies primary catchment planning tool until at least 2027. This project has delivered improvements to SAGIS in three key areas, namely; (1) functionality enhancements to improve the representation of catchment processes, (2) data enhancements to align SAGIS with the second cycle of River Basin Management Planning requirements, and (3) a series of catchment investigations focusing on Natura 2000 sites that provide an up-to-date view on model performance, an understanding of the sources of chemicals and options to minimise the risk to compliance with water quality objectives.

This report is available in a set with UKWIR's published reports on Chemical Source Apportionment, available for purchase together at a reduced price of £600.

Engineering Biological Wastewater Treatment for The Removal of Hazardous Chemicals from Activated Sludge Plants

Reference: 17/WW/04/19
ISBN: 1 84057 847 5
Published Date: 13/12/2017

The aim of this project was to assess if biological treatment processes at wastewater treatment works could be engineered to improve the efficiency of hazardous chemicals (HCs) removal. 

In this case, the effect of the engineering process parameters Solids Retention Time (SRT), Hydraulic Retention Time (HRT), temperature on microbial diversity were studied to identify those conditions that were most conducive for microbial degradation of HCs.
