that cotton is very resistant to textile dye; about 60 percent washes off into wastewater. And it's well known by epidemiologists that kids who live near textile works tend to have high rates of leukemia. There's a company, Bennett and Company, that supplies Polo.com, Victoria's Secret -- they, because of their CEO, who's aware of this, in China formed a joint venture with their dye works to make sure that the wastewater would be properly taken care of before it returned to the groundwater. Right now

After a brief description of the French regulation, this document focuses on the origin of nitrogen in domestic wastewater and on the physical and biological mechanisms involved in its treatment. The design and the nitrogen removal efficiency of different

: si on n’avait pas considéré l’auto-aération de l’écoulement, on aurait choisi un remplissage de 55%, ce qui aurait abouti à un débit de 1,79 m3/s pour un DN600. On aurait alors sous-dimensionné la canalisation. 5. REFERENCES Hager W H (1999). Wastewater hydraulics – Theory and practice. Springer. Lautrich R (1971).
