“…Numerous studies have shown that the removal of COD obtained by ozonation is around 50%-70% [100,101] and many of these studies have applied the process as a tertiary treatment before discharging the treated effluent into sewage or surface water. Using O 3 /H 2 O 2 as an oxidizing agent has been reported with organic matter removal efficiencies around 90% [133,134], while with a combination of persulfate and hydrogen peroxide (S 2 O 8 2− /H 2 O 2 ), under optimum operational conditions, 81% COD and 83% NH 4 -N removals were achieved [102].…”

Abstract:Municipal solid waste final disposal represents an environmental burden worldwide since landfilling, or open dumping, is still the preferred solution for the end of life of solid discarded materials. This study aims to review the technological innovations applied for landfill leachate treatment, taking into consideration the experiences obtained during the past years and the solutions which have been implemented. The review showed that both biological and physiochemical treatments are not able to achieve the requested water quality level, according to the limits established by regulations, whether applied in a single treatment or multiple treatments. In order to respect sustainable release limits to guarantee environmental protection, the construction of depuration systems and combining biological and physiochemical treatment methods is considered of the utmost importance. The review looks at possible joint applications of different treatment techniques reviewed by other studies and considers the state of the art of current research. Combined technical solutions suggested within the 2016 peer-reviewed papers are presented and discussed as a sustainable way to effectively treat landfill leachate, giving particular attention to feasible solutions for developing countries.

“…Haapea et al 2002 reported, that electrical power consumption to produce pure ozone from air is 17-30 kWh/kgO 3. Considering that Salutaguse Yeast Factory has daily 350 m 3 /d of wastewater to be treated using ozonation process it could be proposed that up to 495 gO 3 /d is required.…”

Abstract. The effluents, which are formed from the waste in the process of production of yeast and molasses, contain a large amount of colouring substances (melanoidins, etc.) and can give dark brown painting to the effluent leading to high organic load on the wastewater treatment plant. The purpose of this study was estimation of the process of coagulation as possible method for the post-treatment of effluents of yeast industry. The experiments on the coagulation were carried out using biologically purified effluents of Salutaguse yeast factory. This effluent had relatively high residual content of COD (with the effectiveness of treatment -90%) and brown colour. Different coagulants and flocculants were studied under laboratory conditions. The most effective coagulants FeCl 3 ·6H 2 O and Al 2 (SO 4 ) 3 were studied additionally. The results of this experiment showed a significant decrease of colour and also concentration of COD. Economic analysis for the possible application of coagulants and ozone for the post-treated effluents of yeast factory was also made. The obtained data showed that coagulants and ozone could be used in the process of the post-treatment of effluents of yeast industry for the purpose of decreasing the colour and general concentration of pollutants, however, these processes are very expensive.

Abstract. In this study, the application of ozonation and ozonation with hydrogen peroxide processes for landfill leachate treatment was investigated. The effluents were characterized by COD 710 mgO2/dm 3 and BOD5 72 mg O2/dm 3 . According to the adopted indicators, the determined BOD/COD ratio of 0.1 in raw leachates indicates a stabilized landfill. Ozone was applied at doses of 0.15 -0.6 gO3/dm 3 , and hydrogen peroxide at such doses to keep the weight ratios of H2O2/O3 0.4 -1.6. The maximum COD and UV absorbance removal was respectively 29% and 51% by applying a high ozone dose of 0.6 gO3/dm 3 . After oxidation, the ratio of BOD/COD was increased from 0.1 up to 0.3. It has been shown that by using hydrogen peroxide in ozonation, organic compounds expressed as COD can be efficiently removed from the effluents. The best conditions for the H2O2/O3 process were obtained with a H2O2/O3 ratio of 0.8 and ozone dose of 0.6 gO3/dm 3 . Under these conditions, the removal efficiency of COD was 46%.
