“…During reinjection, clogging of the aquifer can be categorized as physical, chemical, and bio-clogging [4]. It can result from natural physicochemical processes caused by filtration of suspended solids in reinjection water or biological reactions in porous soil media caused by the accumulation of bacterial cells and the production of extracellular polysaccharides [5] [6]. Among them, bio-clogging often leads to a reduction in the hydraulic conductivity of aqueous media by several orders of magnitude [7] [8] [9].…”

To study the mechanism of bio-clogging in a porous medium during the reinjection of geothermal water and to improve reinjection efficiency, an indoor one-dimensional reinjection experiment was conducted based on the geological model of the geothermal reinjection demonstration project in Dezhou City. The biological process of porous media clogging was investigated by analyzing the variation of permeability within the medium, the main indexes of nutrient salts, and the content of extracellular polymeric substances (EPS). High-throughput sequencing, based on 16S rRNA, was used to analyze the characteristics and succession of microbial communities during the reinjection of geothermal water. The results of the study show that significant bioclogging occurs during the reinjection of geothermal water, with an increase in the heterogeneity of the thermal reservoir medium, and a decrease in permeability. The extent of clogging gradually reduces with an increase in seepage path. Thus, thermal reservoir clogging is more serious closer to the water inlet. With an increase in the duration of reinjection, the permeability of the porous medium undergoes three stages: "rapid", "decline-slow", and "decrease-stable". The results show that the richness and diversity of the bacterial community increase and decrease, respectively, during the reinjection process. Bacterial community succession occurs, and the bacterial communities mainly include the Proteobacteria and Bacteroidetes phyla. Pseudomonas and Devosia are respectively the dominant bacteria in the early and late stages of geothermal water reinjection.

“…It is reported that Constructed wetlands (CWs) have been successfully employed to treat domestic sewage for its easy operation and maintain [11,12]. Consequently, the application of CWs for the purification of wastewater has been recently proposed as an alternative for the wastewater treatment and reuse [13][14][15].…”

Constructed wetlands (CWs) have been successfully employed to treat domestic sewage, while it is reported that inconsistent and low nutrient removal efficiency has been achieved. Due to the good performance in other treatment systems, magnetic Fe3O4 nanoparticles (Fe3O4 NPs) can provide a new pathway for the nutrient removal in CWs. In this study, the influences of Fe3O4 NPs on the nutrient removal and variation of microbial community were investigated. The CWs with Fe3O4 had better NH4+-N (ammonia nitrogen, 95.9%), NO3--N (nitrate nitrogen, 83.8%), and TP (total phosphorus, 90.4%) removal percentages than that without Fe3O4. High-throughput sequencing analysis indicated that the microbial community structure could be changed by Fe3O4 NPs. For example, at class level, the major bacteria such as Betaproteobacteria, Gammaproteobacteria and Deltaproteobacteria were promoted by Fe3O4 NPs. On the other hand, at genus level, some abundant genera disappeared, while other abundant genera became dominant in CWs with Fe3O4 NPs, including Desulfuromonas (3.0%), Azospirillum (1.9%), Chryseolinea (1.5%), and Desulfomicrobium (1.8%). The latter genera essentially improved the microbial community involved in the nitrogen removal. Therefore, the CWs with Fe3O4 NPs showed higher NH4+-N and NO3--N removal percentages than that without Fe3O4 NPs.

Well clogging was studied at an aquifer storage transfer and recovery (ASTR) site used to secure freshwater supply for a flower bulb farm. Tile drainage water (TDW) was collected from a 10-ha parcel, stored in a sandy brackish coastal aquifer via well injection in wet periods, and reused during dry periods. This ASTR application has been susceptible to clogging, as the TDW composition largely exceeded most clogging mitigation guidelines. TDW pretreatment by sand filtration did not cause substantial clogging at a smaller ASR site (2 ha) at the same farm. In the current (10 ha) system, sand filtration was substituted by 40-μm disc filters to lower costs (by 10,000–30,000 Euro) and reduce space (by 50–100 m2). This measure treated TDW insufficiently and injection wells rapidly clogged. Chemical, biological, and physical clogging occurred, as observed from elemental, organic carbon, 16S rRNA, and grain-size distribution analyses of the clogging material. Physical clogging by particles was the main cause, based on the strong relation between injected turbidity load and normalized well injectivity. Periodical backflushing of injection wells improved operation, although the disc filters clogged when the turbidity increased (up to 165 NTU) during a severe rainfall event (44 mm in 3 days). Automated periodical backflushing, together with regulating the maximum turbidity (<20 NTU) of the TDW, protected ASTR operation, but reduced the injected TDW volume by ~20–25%. The studied clogging-prevention measures collectively are only viable as an alternative for sand filtration when the injected volume remains sufficient to secure the farmer’s needs for irrigation.
