“…The concentrations of phenol in wastewater released from various industries are listed in Table 1 ( Polat et al 2006;Ucun et al 2010). The inclusion of a wastewater management and pollution control target is, therefore, an essential component of any future water agenda (Karnib 2014).…”

In this paper, the feasibility of the dry stem of Lantana camara waste as an adsorbent to remove phenol from aqueous solution was investigated in a packed-bed column. The effect of bed height (5, 10, 15 cm), initial phenol concentration (100, 150, 250 mg L ) on the adsorption were studied by evaluating the breakthrough curves. The following models were used to assess the column performance: Thomas, Adams-Bohart, Yoon Nelson, Modified dose-response, linear driving force model based on fluid phase concentration difference (LDFC) and linear driving force model based on particle phase concentration difference (LDFQ). The Thomas model and the LDFC model were in good agreement with the experimental data. The bed depth service time (BDST) model was used to predict adsorption performance at other experimental conditions. The maximum adsorption capacity was found to be 149.77 mg g −1 , confirming that Lantana camara is a suitable adsorbent for the removal of phenol from aqueous solution.

“…Moreover, modeling-based predictions of effluent quality resulting from wastewater treatment processes application or modernization were analysed in numerous studies including developed (Druart et al 2016;Vialkova et al 2020) and developing countries (Heddam et al 2016;Karnib 2014). Within main threats to the aquatic ecosystems mainly inorganic nutrient compounds such as N-NH 4 , nitrates (N-NO 3 ), nitrites (N-NO 2 ) and P-PO 4 were identified as the most hazardous to aquatic vegetation due to the eutrophication process acceleration causing an ecosystem imbalance (Kemp et al 2005;Wang and Wang 2009).…”

The study is an attempt to assess the pollution impact on the aquatic ecosystem related with an emergency discharge of untreated municipal wastewater from the "Czajka" wastewater treatment plant (WWTP) in Warsaw. The present case study is based on the analysis of available monitoring data for chemical oxygen demand (COD), total nitrogen (TN), ammonia nitrogen (N-NH 4), and total phosphorus (TP) in the effluent mixing zone (MZ), the stretch of the river and before the discharge point. Data analysis was supported by a basic statistical analysis based on Pearson's correlation coefficient. The results proved the importance of efficient and reliable nutrient removal technologies used in modern WWTPs. A statistically significant correlation was achieved between the COD (r = 0.567) and TP (r = 0.714) discharged loads and their concentration in the MZ. However, no significant correlation has been identified with TN and N-NH 4. Furthermore, the dissolved oxygen (DO) deficits in the MZ were observed within 7 days of the discharge period resulting in an average DO concentration decrease from 8.4 to 7.1 mgO 2 /L. The river stretch has not been affected by DO deficits while the average observed DO concentration 30 km behind the discharge point was 9.1 mgO 2 /L. The analysis results present the pollutants assimilation capacity of a river ecosystem and its real reaction to sudden excessive nutrient loads discharge.

Bu çalışmada süt endüstrisi atıksularından kaynaklanan peyniraltı suyunun koagülasyon/flokülasyon yöntemiyle kimyasal arıtımı amaçlanmıştır. Peyniraltı suyunun kimyasal arıtımı, jar testi deneyleriyle yürütülerek en iyi pH aralığında optimum koagülant cinsi ve dozu belirlenmiştir. pH (4,0-8,5) ve koagülant dozunun (0,25-2,0 g/L) KOİ (kimyasal oksijen ihtiyacı) giderim verimine etkisini incelemek üzere kesikli deneyler yapılmıştır. Koagülant olarak demir sülfat, alüminyum sülfat (alum) ve kil (montmorillonit) kullanılmıştır. Optimum koagülant dozu 1,0 g/L ve pH 7,0 olarak belirlenmiştir. Kil, alum+kil, demirsülfat+kil için sırasıyla %88, %91 ve %92 KOİ giderim verimi ve %89, %93 ve %95 AKM (askıda katı madde) giderim verimi elde edilmiştir. Yapılan kimyasal arıtma deneylerinde montmorillonitin diğer koagülantlarla birlikte ön arıtım amacıyla kullanılabileceği sonucuna varılmıştır. Ancak su kirliliği kontrol yönetmeliğinde belirtilen deşarj standartları sağlanamadığı için kimyasal arıtımın sadece kendinden sonraki ünitenin yükünü hafifleteceği tespit edilmiştir.
