First Flush Stormwater Runoff from Highways

Bridging the Gap, 2001
Stormwater is now receiving attention from regulatory agencies and has become an important component in watershed planning. In many cases, pollutant mass emissions from stormwater exceed those from wastewater treatment plants. Land use has been identified as an important parameter in predicting stormwater quality.

Seasonal first flush phenomenon of urban stormwater discharges

Water Research, 2004
California's climate, typified by winter and spring precipitation and summer drought, is often called a Mediterranean climate, and creates a long period for pollutant build-up. The initial storms of the winter season usually have higher pollutant concentrations, which is called a seasonal first flush.

First Flush of Organics in Highway Runoff

Global Solutions for Urban Drainage, 2002
Stormwaters from three highway sites were monitored over two wet seasons for organics, Chemical oxygen demand, oil and grease and polyaromatic hydrocarbons (PAHs) were measured. The sites exhibited a first flush in most cases for most parameters. The mass first flush ratio (the ratio of the normalized transported mass of pollutant to the normalized ...

Probability mass first flush evaluation for combined sewer discharges

Journal of Environmental Sciences, 2010
The Korea government has put in a lot of effort to construct sanitation facilities for controlling non-point source pollution. The first flush phenomenon is a prime example of such pollution. However, to date, several serious problems have arisen in the operation and treatment effectiveness of these facilities due to unsuitable design flow volumes and ...

Storm Flow from First-Flush Precipitation in Stormwater Design

Journal of Irrigation and Drainage Engineering, 2004
Regulations for mitigating nonpoint source pollution from urban areas often include a requirement for treatment of a first-flush depth of stormwater. When the stormwater treatment technology requires specification of a design flow rate, the first-flush depth must be related to a first-flush flow rate. This paper describes a methodology to determine the

First flush pollution load of urban stormwater runoff

Journal of Environmental Engineering and Science, 2004
In a storm event, a first flush (FF) phenomenon occurs when most of the pollution load is transported in the initial part of the event discharged volume. The objectives of the study were to consider its severity for a number of pollutants as well as to recognize rainfall–runoff characteristics that influence it.

Low-Cost Filtration System to Treat First-Flush Stormwater

Water, Air, & Soil Pollution: Focus, 2009
The aim of this paper is to evaluate the performance of the low-flow filtration system (LFFS) that Kogarah Municipal Council developed for treating and reusing the highly polluted first-flush stormwater (FFSW) while allowing the cleaner subsequent major stormwater flows to be directed to the major street drainage.

Fractional Kinetic Model for First Flush of Stormwater Pollutants

Journal of Environmental Engineering, 2005
By generalizing the urban ground as a fractal surface and revising the classical Fick's formula as a law of dispersion with a fractional-order derivative, a fractional kinetic model is developed for simulation of the first flush phenomenon of urban stormwater pollutants.
