1. A method for pretreatment of wastewater for reduction of total suspended solids (TSS), chemical oxygen demand (COD) and turbidity, wherein the wastewater is from olive oil mills, wineries, piggeries, cowsheds, dairy effluents, slaughterhouses, fruit and vegetable processing industry, or soy or coffee bean industry, and includes charged colloidal particles suspended therein, said method consisting of treating the wastewater in one single step, wherein said single treatment step comprises treating the wastewater with a nanocomposite consisting of an anchoring particle and one or more polymers, at least one of said polymers being a polyelectrolyte polymer, whereby neutralization of the charged colloidal particles suspended in said wastewater occurs while bridging between charged colloidal particles and anchoring the charged colloidal particles to the anchoring particles, thus enhancing their aggregation and precipitation and achieving a reduction of TSS and turbidity in a time within the range of minutes to tens of minutes. |
