Bimbo – Ricolino candy manufacturing plant in Mexico City was discharging wastewater with high amount of fats oil and grease and dissolved sugars. Local regulatory agency requested that suspended solids, oil and grease and dissolved BOD be almost completely removed prior to discharge to municipal plant. The available real estate in Mexico City was very limited. A multistep treatment system was ...

Wastewater was collected from the Dheradun industrial area situated in capital of uttrakhand. Samples were collected between the periods of November 2010 to Aug.2011 determine the following parameters, pH, temperature, turbidity, chemical oxygen demand (COD), Biological oxygen demand(BOD), dissolved oxygen (DO), conductivity, total dissolved solid (TDS), total suspended solid (TSS), sulphate, n...

Nowadays recycling wastewater is a task in progress. New ways of contamination have appeared together with the technology development. Our article deals with the case of wastewater contaminated with dispersed colorants that are used during the decoration of paper boxes for packaging various products. The wastewater treatment is based on the electro-flotation process. The system is fully automat...

Hookworm infection contributes around 700 million infections worldwide especially in developing nations due to increased use of wastewater for crop production. The effective recovery of hookworm ova from wastewater matrices is difficult due to their low concentrations and heterogeneous distribution. In this study, we compared the recovery rates of (i) four rapid hookworm ova concentration metho...

Abstract To solve the problems of unstable chemical oxygen demand (COD), turbidity and suspended solid (SS) removal for electrocatalytic process operation subsequent ultrafiltration membrane–reverse osmosis membrane in a centralised fracturing wastewater treatment plant Inner Mongolia, integrated dissolved ozone flotation (DOF) was proposed to replace original process. Multiple processes, such ...
