Micropollutant removal by advanced oxidation of microfiltered secondary effluent for water reuse

Real-time control of micropollutant removal from secondary effluent by ozonation

Ozonation has shown to be a promising technology in removing micropollutants from wastewater effluent but current basic control strategies still result in sub-optimal ozone dosing. This work aimed at applying novel, yet simple, surrogate models (based on delta UVA254), to assess the micropollutant removal on pilot-scale as a proof-of-concept. Different events and fluctuations in effluent condit...

Advanced Oxidation Process for Haloacetic Acid Removal in Tehranpars Water Treatment Using CuO Nanocatalyst

Potentially harmful disinfection byproducts (DBPs), as a significant challenge in water treatment, are formed when oxidizing disinfectants react with natural organic matters (NOM). Unfortunately, an  unwanted  side  effect  is  the  formation  of  harmful by-products,  such  as  THMs  and  HAAs, following the chlorination stage. DBPs  cause a variety of diseases like cancer in humans.  In this ...

advanced treatment of sahebgharanieh secondary effluent by ozonation

chemical oxidation is one of the most suitable treatment methods for reducing organic pollutants and the number of pathogens remaining in secondary effluents. ozone is the most powerful oxidizing agent commonly used because of it's many advantages over chlorination. in this study the efficiency of ozonation in advanced wastewater treatment of sahebgharanieh plant has been determined. ozone gene...

A hybrid process of biofiltration of secondary effluent followed by ozonation and short soil aquifer treatment for water reuse.

The Shafdan reclamation project facility (Tel Aviv, Israel) practices soil aquifer treatment (SAT) of secondary effluent with hydraulic retention times (HRTs) of a few months to a year for unrestricted agricultural irrigation. During the SAT, the high oxygen demand (>40 mg L(-1)) of the infiltrated effluent causes anoxic conditions and mobilization of dissolved manganese from the soil. An addit...
