    Opis:
    The effectiveness of co-treatment of leachates from an old site of municipal landfill with a dairy industry wastewater in a membrane bioreactor has been investigated. The subjects of the study were leachates collected at the municipal landfill in Tychy and dairy wastewaters from Dairy Plant in Bieruń. The determination of the most effective technological parameters of the process, i.e. activated sludge load and its concentration and types of COD fractions in the reactor influent was made. It was shown that the activated sludge load at the level of 0.06 g COD/(gDM·d) was the highest permissible one among all the investigated loads and the process run effectively within the whole investigated range of concentrations of activated sludge in a bioreactor. It was found that in the treated wastewater, the fraction of easily degradable organic compounds was the dominant one.

    Opis:
    The advanced oxidation process with Fenton’s reagent can be used in industrial wastewater treatment, especially for the degradation of not easily biodegradable contaminations. Chemical oxidation of industrial wastewater or other substances as a pre-treatment before biological purification is the most effective method of wastewater treatment. However the Fenton process requires low pH of wastewater and final neutralization with a big amount of iron-containing precipitate. Thes paper presents laboratory experiments dealing with the treatment of adhesive wastewater in an sequencing batch reactor following the Fenton process without final neutralization.

    Opis:
    A novel three-dimensional electrode reactor (3DER) was designed to treat the dye wastewater. The performance of 3DER was evaluated via methyl orange (MO) removal efficiency. For comparison, the performance of the two-dimensional electrode reactor (2DER) was also assessed. Furthermore, the effects of electrolyte and aeration on treatment performance were preliminarily evaluated to further optimize the operation on 3DER. A repeatable and stable MO treatment efficiency was obtained in the 3DER. The MO removal rate reached 79.5% at the applied voltage of 1.0 V, electrode spacing of 2 cm and initial MO concentration of 60 mg/dm3, significantly higher than that in the 2DER (58.8%), suggesting the obvious improvement of particle electrodes on MO removal. Both adding electrolyte and air sparging into the 3DER contributed to the enhancement of the MO removal rate. These results obtained here suggest that the 3DER may provide an effective alternative for the treatment of azo dye wastewater and/or non-biodegradable industrial wastewaters.

    Opis:
    Every year, a large amount of mineral processing wastewater is discharged from various industries into the environment which is considered a challenging task not only because of its large volume, but more importantly, its hazardous components, while its reuse as feedwater without proper treatments causes great harm to the final product of these industries. Cost-effective methods are required to treat a wide range of industrial wastewater in a diverse range of conditions. In this study, a combined hydrocyclone-electrocoagulation system is tried to treat the wastewater for industries with high water consumption and high pollutants such as paper industry, iron and metal forming industry, and marble industry. The effects of the hydrocyclone operational parameters, such as feed inlet pressure and diameter, vortex finder diameter, apex diameter, and feed solids content, were investigated. In the case, wastewater of paper industry, the following optimum conditions $(P = 4.5$ bar, $D_o = 15.8 mm, D_u = 6 mm, D_i = 4 mm and c_s = 2.3%)$ were achieved. An overflow of about 90.58% water recovery and 21.45% solid at 75.92% separation efficiency was obtained. The results showed that the hydrocycloneelectrocoagulation treatment has efficiently treated the three different types of industrial wastewater. The chemical oxygen demand (COD), biochemical oxygen demand (BOD), total solid (TS), total suspended solids (TSS), colour and turbidity, were reduced sharply and met the effluent discharge or reuse standards. Also, compared with the hydrocyclone-treated wastewater, the hydrocyloneelectrocoagulation-treated wastewater was found to be more enhanced.
