Optimizing first flush diverter for urban stormwater pollution load reduction by most efficiently utilizing first flush phenomena

Journal of Environmental Management, 2023
In order to find the optimal design of first flush diverter, this study shifts the focus of first flush research from the existence of first flush phenomenon to utilization effect of the phenomenon. The proposed method consists of four parts: (1) key design parameters, which describing key structure of first flush diverter rather than first flush ...

First flush in a combined sewer system

Chemosphere, 2008
Pollutant first flush was examined in an urban catchment with area of 12.7 ha and drained by a combined sewer system located in northern Italy. A total of 23 rainfall-runoff events were monitored and 281 samples were analyzed. The selected quality parameters were biochemical oxygen demand, chemical oxygen demand, suspended solids, settleable solids ...

First flush analysis of urban storm runoff

Science of the Total Environment, 2002
Stormwater runoff was monitored on 13 separate urban watersheds, which were chosen to represent distinct types of residential and industrial development, along with various watershed characteristics. A total of 38 storm events were monitored to investigate the first flush phenomenon.

Quantifying the first-flush phenomenon: effects of first-flush on water yield and quality [PDF]

, 2009
First-flush diversion is increasingly recognised as a useful intervention to reduce both suspended and dissolved contaminate loads in rainwater systems. Such first flush systems rely on the early rain to wash the roof before water is allowed in the store.

Quantifying the first flush phenomenon [PDF]

, 2005
Removing the first millimetres before rainwater is diverted to a store is a much-used method for ensuring high water quality in rainwater harvesting systems. Such first-flush systems rely on the initial rain to partly wash the roof before runoff water is allowed in the store.

The first flush load of urban surface runoff

Water Research, 1998
The treatment of urban surface runoff is steadily becoming common practice. Good management of treatment works requires an understanding of the first flush phenomenon of wet weather flow in urban drainage systems. The objective of this paper is to analyse evidence for the existence and nature of the first flush load of pollution input into drainage ...

Implications of a kinematic wave model for first flush treatment design

Water Research, 2006
A deterministic model was developed to predict pollutant mass first flush and to utilize it for better design of best management practices (BMPs) that focus on treating the first flush. The model used the kinematic wave equation to calculate flow and mass transport, and erosion equations to calculate pollutant concentrations, which were assumed to be ...
