“…The group of AOPs can be further subdivided manifold in terms of their mechanisms of action and areas of application, with developmental issues and outcomes continuing to evolve (Garrido-Cardenas et al 2019). Other areas of application can be, for example, the treatment of leachate or the treatment of drinking water (Sillanpää et al 2018;Hassan et al 2021).…”

Carrier-bound titanium dioxide catalysts were used in a photocatalytic ozonation reactor for the degradation of micro-pollutants in real wastewater. A photocatalytic immersion rotary body reactor with 36 cm disk diameter was used, which was irradiated using UV-A LEDs. The rotating disks were covered with catalysts based on stainless steel grids coated with titanium dioxide. The dosing of ozone was carried out through the liquid phase via an external enrichment and a supply system transverse to the flow direction. The influence of irradiation power and ozone dose on the degradation rate for photocatalytic ozonation was investigated. In addition, the performance of the individual processes photocatalysis and ozonation were studied. The degradation kinetics of the parent compounds were determined by LC-MS/MS. First-order kinetics were determined for photocatalysis and photocatalytic ozonation. A maximum reaction rate of the reactor was determined, which could be achieved by both photocatalysis and photocatalytic ozonation. At a dosage of 0.4 mg /mg DOC, the maximum reaction rate could be achieved using 75% of the irradiation power used for sole photocatalysis, allowing increases in the energetic efficiency of photocatalytic wastewater treatment processes. The process of photocatalytic ozonation is suitable to remove a wide spectrum of micro-pollutants from wastewater. HIGHLIGHT within the work, reaction rates for the degradation of micropollutants in real wastewater matrix are presented. due to the number of investigated pollutants as well as the practical investigation conditions, a more precise evaluation of the use of photocatalysis and photocatalytic ozonation for wastewater treatment is possible.

“…According to previous studies (Hassan et al, 2021; Rookesh et al, 2022), the condition of pH 6.0 was chosen for biological treatment. At this pH, it was obtained the lowest NH 4 + concentration (270.5 mg/L), moderate COD (662 mg/L), and total phenol concentration (61.5 mg/L).…”

In this study, a hybrid process for leachate wastewater treatment including evaporation and reverse osmosis (RO) membrane or biological treatment systems was suggested. Experiments were performed on a real landfill leachate wastewater. The leachate was subjected to evaporation; as a result, a distillate was obtained containing less organic matter and less substantial amounts of other pollutants, as ammonium salts and total phenols were removed.

“…However, these methods are usually not properly managed, and may present many disadvantages such as infiltration of leachate into groundwater and emission of toxic gases. Unfortunately, liquid and solid waste are released directly into the public sanitation network and uncontrolled landfill, respectively, without any prior treatment 5,6 . Slaughterhouse discharges have negative impacts on the environment, including groundwater, surface water and soil pollution, pathogen generation and disease.…”

Slaughterhouses generate highly polluted effluents, and if not treated before discharge can cause major adverse environmental and public health impacts. Treatment of this waste by anaerobic digestion can reduce those impacts while producing a potentially valuable source of energy. The purpose of this study was to investigate this process efficiency under pilot operating conditions for a more accurate scaling up. Blood waste from a slaughterhouse was treated in a pilot-scale digester of 30 dm 3 total volume under mesophilic temperature conditions. Operating parameters
