Physico‐chemical characteristics and biodegradability of primary effluent and particulate matter removed by microscreens
In this study, the physical, chemical, and biological characteristics of raw wastewater were compared with the liquid and solid streams generated by a primary clarifier (PC), a rotating belt filter (RBF, 350 μm), and a drum filter (DF, 60 μm) and series (SER) combination of an RBF with a PC or a DF...

description | In this study, the physical, chemical, and biological characteristics of raw wastewater were compared with the liquid and solid streams generated by a primary clarifier (PC), a rotating belt filter (RBF, 350 μm), and a drum filter (DF, 60 μm) and series (SER) combination of an RBF with a PC or a DF using pilot‐scale primary treatment units. The RBF removed about 36% of the influent total suspended solids. The DF and PC yielded an influent total suspended solid removal of 47% to 55% in both individual (parallel) and SER configurations. The size fractionation and chemical characterizations of the liquid fractions indicated a significant change in the wastewater composition in both filter configurations with no variation in the biodegradability of liquid fractions. The solids recovered by RBF had a higher total solids (TS) concentration and a higher volatile solids (VS) content (0.92 g VS/g TS) than that of DF and PC treatments (0.58 to 0.84 g VS/g TS). DF and PC sludge demonstrated a higher biodegradability rate (k1; 0.11 d−1 |

These results indicated that the physical, chemical, and biological characteristics of liquid and solids from different filter configurations are required to determine design criteria to upgrade or retrofit water resource recovery facilities using an RBF or a DF.
Practitioner Points
A rotating belt filter (RBF) removed less solids than a drum filter (DF) or a primary clarifier (PC).
A series configuration of an RBF with either a DF or PC resulted in an effluent with a lower proportion of slowly biodegradable organic matter than in a parallel configuration.
Solids from an RBF, a DF, or a PC had similar theoretical biochemical methane potential.
Quantitative physical (including size fractionation), chemical, and biological characterizations of treated wastewater and solids removed by micro‐sieving technologies are required to optimize design criteria of units located downstream of these technologies for further liquid and solids treatment.</description><identifier>ISSN: 1061-4303</identifier><identifier>EISSN: 1554-7531</identifier><identifier>DOI: 10.1002/wer.10854</identifier><identifier>PMID: 36965038</identifier><language>eng</language><publisher>United States: Blackwell Publishing Ltd</publisher><subject>Belt filters ; Biodegradability ; Biodegradation ; Chemical oxygen demand ; Clarifiers ; Configurations ; Design criteria ; Drum filters ; Effluents ; Fractionation ; Influents ; Methane ; micro‐sieving ; Organic matter ; organic matter recovery ; Oxygen ; Oxygen requirement ; Particulate Matter ; primary treatment ; Raw wastewater ; Resource recovery ; Retrofitting ; Rotation ; Sewage - chemistry ; Sludge ; Solid suspensions ; Suspended particulate matter ; Total suspended solids ; Volatile solids ; Waste Disposal, Fluid - methods ; Wastewater ; Wastewater composition ; Water resources</subject><ispartof>Water environment research, 2023-04, Vol.95 (4), p.e10854-n/a</ispartof><rights>2023 The Authors. published by Wiley Periodicals LLC on behalf of Water Environment Federation.</rights><rights>2023 The Authors.
