“…The understanding of wastewater characteristics plays a vital role for developing the wastewater treatment plant via determination of wastewater quality parameters (Nazif et al 2023). The wastewater characteristics of the pharmaceutical manufacturing units vary greatly according to the raw materials consumed, equipment used and variations in the synthesis, compounding and formulation processes (Rana et al 2017).…”

The annual growth rate of pharmaceutical industry in Pakistan is 10% and is continuously expanding to fulfill the increasing demand of the rapidly growing population. But inability of the pharmaceutical sector to comply with the environmental standards leads to the introduction of large quantities of various pollutants in the natural environment which presents serious ecological challenges. In this study, effluent wastewater samples from 14 manufacturing units of the pharmaceutical industries of the National Industrial Zone, Rawat, Pakistan, were collected and characterized for physicochemical parameters including color, odor, pH, electric conductivity, temperature, total dissolved solids, total suspended solids, salinity, dissolved oxygen (DO), chemical oxygen demand (COD), nitrates, sulfates and phosphates according to the standard methods. The detection and quantification of diclofenac (DCF)—one of the commonly prescribed drugs in Pakistan—were carried out in the pharmaceutical wastewater samples (PWWSs) using HPLC-PAD. Exceptionally high concentration of the diclofenac was detected in the industrial disposal of MB-12 (311,495 µg L−1). PWWSs were analyzed using chemometric techniques including principal factor analysis (PFA) and cluster analysis (CA). PFA explained almost 81.48% of the total variance by the newly extracted four components and complemented the strong Pearson’s correlation coefficient (r) of DCF concentrations to that of the levels of COD, r = 0.752, and DO, r = − 0.609, in PWWSs. Six clusters were generated during similar wastewater characteristics-based CA dendrogram, in which reverse osmosis-treated PWWSs were observed to cluster with the untreated PWWSs, suggesting the need to adopt an advance and better wastewater treatment methods by the pharmaceutical industries.

Activated sludge has a high diversity of infectious agents. However, many of these microorganisms contribute greatly to the biological treatment process due to the enzyme production and capability for degrading a wide range of organic compounds in wastewater. The present review discusses the potential of aerobic granular sludge as a bio-startup (AGS-BS-up) for new wastewater treatment plants. The complex microbial community in activated sludge was investigated using 16S metagenomic analysis. The potential of aerobic granular sludge prepared from activated sludge to be used as a bio-starting medium for food wastewater treatment plants (FWWTP) was discussed. AGS-BS-up appears to have high applicability to enhance the biological treatment of food wastewater (FWW). The hypothesis behind using aerobic granular sludge as a bio-startup for FWWTP lies in the high microbial biodiversity in the aerobic granular sludge, which contributes effectively to the biological treatment of food wastewater. Based on the previous studies, the AGS-BS-up is efficient in improving the quality of FWW to meet international standards required for safe disposal into the environment.
