Chemical treatability of dairy wastewater, originating from a dairy and dairy products plant at Istanbul was investigated on the basis of chemical oxygen demand (COD) parameter as a pre‐treatment alternative. FeCl3, FeSO4 and alum were used as coagulants in the jar‐test experiments of four sets of daily composite ,wastewater, samples taken once every month.

FeCl 3 is also produced as an atmospheric salt aerosol by reaction between iron-rich dust and hydrochloric acid from sea salt. This iron salt aerosol causes about 5% of naturally-occurring oxidisation of methane and is thought to have a range of cooling effects.
