In this study, non-woven MBR was used to treat hydrolysed biosolids wasted from a biological treatment plant. The concentration of SS of hydrolysed biosolids in influent was 10,000 mg/L and the concentration of SS in effluent was less than 200 mg/L with/without discharging wasted sludge depending on different HRTs, i.e. 20, 15 and 10 d. The results indicated that the percentage of biosolids reduction in terms of SS removal efficiency in non-woven MBR was around 65, 60 and 35%, respectively, depending on different HRTs. Meanwhile, the ratio of VSS/SS was decreased from 0.78 to 0.50 and the number of smaller inorganic particle sizes increased due to extended SRT. The initial flux in the non-woven MBR was set at 0.02, 0.04 and 0.06 m3/m2/day and trans-membrane pressure (TMP) was less than 10 kPa. The permeate flux could be maintained quite stably due to lower TMP. The proposed non-woven MBR could be used to achieve the reduction of biosolids in the wastewater treatment plant.

Abstract:Phosphorus is a major substance that is needed especially for agricultural production or for the industry. At the same time it is an important component of wastewater. At present, the waste management priority is recycling and this requirement is also transferred to wastewater treatment plants. Substances in wastewater can be recovered and utilized. In Europe (in Germany and Austria already legally binding), access to phosphorus-containing sewage treatment is changing. This paper dealt with the issue of phosphorus on the sewage treatment plant in Nitra. There are several industrial areas in Nitra where record major producers in phosphorus production in sewage. The new wastewater treatment plant is built as a mechanicalbiological wastewater treatment plant with simultaneous nitrification and denitrification, sludge regeneration, an anaerobic zone for biological phosphorus removal at the beginning of the process and chemical phosphorus precipitation. The sludge management is anaerobic sludge stabilization with heating and mechanical dewatering of stabilized sludge and gas management. The aim of the work was to document the phosphorus balance in all parts of the wastewater treatment plant - from the inflow of raw water to the outflow of purified water and the production of excess sludge. Balancing quantities in the wastewater treatment plant treatment processes provide information where efficient phosphorus recovery could be possible. The mean daily value of P tot is approximately 122.3 kg/day of these two sources. The mean daily value of P tot is approximately 122.3 kg/day of these two sources. There are also two outflows - drainage of cleaned water to the recipient - the river Nitra - 9.9 kg Ptot/day and Ptot content in sewage sludge - about 120.3 kg Ptot/day - total 130.2 kg Ptot/day.
