It resulted in a 3- to 5-fold increase in True colour and Dissolved Organic Carbon (DOC), representing an increase of Natural Organic Matter (NOM), in Nepean Dam, south of Sydney, New South Wales, Australia. The increased NOM caused the formation of ‘weak flocs’ in the coagulation process that broke up in dual media gravity filters, resulting in a premature backwash and short filter run time. There is no practical method to measure ‘floc strength’ in an operating water treatment facility. This research identified a novel method to assess the ‘flocs condition’ during filtration, either ‘weak’ or ‘strong’, by calculating the rate of turbidity change and reporting it as a ‘turbidity breakthrough slope’ in NTU/day (NTU/d). The end-of-run head loss of the filter represents the energy at which the flocs break. Consequently, this research used the end-of-run head loss of a filter to measure floc strength. The turbidity breakthrough slope and filter end-of-run head loss are linearly correlated, and by using the correlation, a novel Floc Strength Model (FSM) has been developed. Applying the FSM at Nepean Water Filtration Plant (WFP), for ‘very strong flocs’ and ‘very weak flocs’ conditions, the calculated ‘floc strengths’ were 2.2 m and 0.57 m (measured in ‘meter (m)’ of water column), respectively. The FSM is a practical and in-situ method to monitor ‘floc strength’ in real time during a filter operation. It enables dynamic optimisation of water treatment. As soon as the filtered water turbidity starts to increase (start of turbidity breakthrough) in a filter, the FSM calculates and predicts the low ‘floc strength’ (end-of-run head loss) of the ‘very weak flocs’ and accordingly predicts the run time of the filter. Plant operators can then proactively optimise the chemical doses to change the flocs condition to ‘very strong flocs’ and improve ‘floc strength’ and filter run time before the end of the filter operation cycle.</div></div>","PeriodicalId":17528,"journal":{"name":"Journal of water process engineering","volume":"77 ","pages":"Article 108345"},"PeriodicalIF":6.3,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144696914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pyrolysis can convert waste into valuable products such as biochar and syngas. This study investigates the co-pyrolysis of rubber tree waste (RT) and pipe sludge (PS) to produce Fe-biochar, which was utilized as a reactive medium for formic acid (FA)-mediated Cr(VI) removal. Pyrolysis was performed at varying RT-to-PS mass ratios, and the physicochemical properties of the resulting Fe-biochars were analyzed. Syngas monitoring and biocrude composition analysis were scrutinized to experimentally assess the catalytic effects of PS on the pyrogenic product formation. The Cr(VI) removal performance of the composite was explored in de-ionized water (DIW) and groundwater (GW) conditions, while computational fluid dynamics (CFD) modeling was employed to evaluate its field-scale applicability. The results demonstrate that PS played a key role in enhancing syngas (CO) production, which simultaneously limited biocrude formation. Fe-biochar produced at 800 °C exhibited the highest Cr(VI) removal efficiency due to its well-defined porous structure and the presence of redox-active Fe phases (Fe⁰ and FeO). The biochar showed higher Cr(VI) removal in GW than in DIW, attributed to formation of Fe-SO₄²⁻ complexes, which enhanced redox reactions with Cr(VI). CFD modeling demonstrated the potential of Fe-biochar for field-scale GW remediation, highlighting the importance of optimized formic acid (FA) injection in Cr(VI) removal. These findings signify that the co-pyrolysis of RT and PS offers an eco-friendly waste management approach, while providing an effective medium for remediating water pollution.</div></div>","PeriodicalId":17528,"journal":{"name":"Journal of water process engineering","volume":"77 ","pages":"Article 108387"},"PeriodicalIF":6.3,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144686356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The system demonstrated a treatment capacity of 5 m³/h for ASP flooding produced water.

This paper tries to dig out the latest advances and experiences in pilot and industrial practices for the acceleration of lithium recovery from OGPW. Lithium is observed abundant in oil/gas fields of the selected basins in the USA, Canada and China. From the points of industrial practice and economic feasibility, this paper emphasizes the importance of enhanced pretreatment before lithium adsorption, and proposes a serious of pretreatment targets for produced water. Regarding lithium recovery, the U.S. and Canada are initiating their commercial projects based on demonstration tests, while China is advancing several full-process pilot scale experiments. Positive achievements have been made, including pretreatment technologies, adsorbent selection, scale control and product purification, etc., and the problems and solutions in pilots are presented almost firstly by this paper in the literature. The direct lithium extraction (DLE) technology coupling adsorption and membrane separation has become the dominant process for lithium recovery from produced water, and the aluminum-based adsorbent is recommended as the optimal choice for industrial practice in the near few years. Economically, higher lithium concentrations and lower deep pretreatment costs enhance the feasibility of lithium extraction from OGPW. Lithium developers are positive in recovery of OGPW with Li ≥75 mg/L. If the deep pretreatment costs are controlled within 10 CNY/m³, OGPWs with Li ≥50 mg/L might be financially feasible for lithium recovery.</div></div>","PeriodicalId":17528,"journal":{"name":"Journal of water process engineering","volume":"77 ","pages":"Article 108356"},"PeriodicalIF":6.3,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144686379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ecological consequences of these photocatalysts were evaluated using SimaPro software, which encompasses 18 environmental impact categories and Cumulative Energy Demand (CED). The results of this study indicated that, in most environmental indicators, the rGH photocatalyst had the highest environmental impact, except for terrestrial biotoxicity (TE) and human non-carcinogenic toxicity (HNCT).

Moreover, the analysis of the four photocatalytic processes revealed a significant impact on human health.
