Opis:
Monthly reports from June 2017 to May 2018 of Twenty-one wastewater treatment plants in Sharkia were evaluated for the following parameters: temperature, pH, total dissolved solids (TDS), total suspended solids (TSS), chemical oxygen demand (COD), biochemical oxygen demand (BOD), nitrate (NO3), oil and grease (O&G) and Dissolved Oxygen (DO) values. The first aim of this study was to estimate the main wastewater per capita pollution generation per day (PCPL) and found that the 90th percentile PCPL for TSS, COD, BOD, NO3 and O&G were equal to 57.42, 91.59, 59.13, 1.64 and 12.39 (g/capita/day) respectively. The second aim was to assess the performance of the WWTPs in the governorate, by calculating of the wastewater quality index (WWQI) of each plant and for the entire governorate which shows that; 2 WWTPs gives a good performance, 9 WWTPs gives a fair performance, 9 WWTPs gives a marginal performance and 1 WWTP is in bad conditions, the average performance all over the governorate is considered marginal. A simple empirical formula had been established to be used for calculation of the WWQI based on the tested parameters using the multiple linear regression and found to be very effective in predicting the WWQI for the WWTPs.

Opis:
In this study, the effect of thermal pre-treatment (TP) on the physical characteristics and co-digestion of a mixture of food waste and sludge was investigated. The food waste (FW) to sewage sludge (SS) ratio used in this research is 1:2 (VS-based) to form a final concentration of 11.20%. The inoculum to substrate ratio was set at 1:1 (volumebased). Undoubtedly, the results show that TP has changed the physical characteristics of the food waste to sewage sludge mixture. The results show that the pretreatment increased the biogas production from 4385 ml for the untreated reactor to 5685 for the reactor R2(140) at 140 °C and the improvement in biogas production reaches 29.65% in the reactor R2(140) and the removal of volatile solids was 58.90%. Therefore, after the biomethane potential test, the temperature of 140 °C was found to be optimal in the production of biogas. The optimal condition is to use a mixture of pre-treated SS at the temperature of 140 °C and untreated FW, so TP is recommended to be used in anaerobic digestion of the mixture of food waste and sewage sludge.
