Recent technological developments and challenges for phosphorus removal and recovery toward a circular economy

Environmental Technology & Innovation, Год журнала: 2023, Номер 30, С. 103114 - 103114

This review aims to summarise the current state of art technologies for phosphorus recovery from waste and wastewater. Information corroborated here shows a clear relationship between PO4-P content in liquid phase cost recovery. In fact, all commercial scale operations this involve phosphorus-rich stream. most cases, is achieved via two key steps: solubilising into water then phosphate chemical precipitation/crystallisation. Recent development has also included enrichment pre-treatment rich Phosphorus contaminant aquatic environment. Thus, work reviews post-treatment stream after environmental discharge or reuse. places spotlight on requirement further research especially at pilot- full-scale level. The demonstrates need complement process precipitation.

Constructed Wetlands Process for Treating Sewage to Improve the Quantitative and Qualitative Management of Groundwater Resources

IntechOpen eBooks, Год журнала: 2023, Номер unknown

Опубликована: Март 15, 2023

Water scarcity limits access to safe water for drinking and communities face some form of stress, which can be related insufficient supplies or inadequate infrastructures. Climate change plays a crucial role in stress worldwide, as rising temperatures lead more unpredictable weather extreme events. In this challenge, the need seek an alternative protect groundwater resources decrease use public is imposed. Sewage management seems significant treatment removing contaminants undesirable components from polluted waters safely return it environment irrigation other uses. For consideration, many technologies are discussed literature including biological, physical chemical processes. Among biological processes principally used sewage figured constructed wetlands. Constructed wetland system considered economic, efficient environmentally friendly method, based on adsorption retention pollutants by substrates, sorption plants, decomposition microorganisms. Therefore, chapter book throws will light principal mechanisms responsible organic matter, nitrogen phosphorus removal different types wetlands, provides recommendations concerning factors affecting performance wetlands sewage.

Study on city tail water treatment in constructed wetland with straw biochar substrate modified by freeze–thaw cycles

Environmental Technology & Innovation, Год журнала: 2022, Номер 28, С. 102831 - 102831

The preparation of biochar is one the important directions to realize high-value resource utilization straw. Constructed wetland (CW) has low cost and high efficiency in treating city tail water. In order improve purification rate CW with straw for water, freeze–thaw cycles (FTCs) modification application FTCs-modified were studied. relatively optimal condition was eight FTCs. adsorption CO2 on increased by more than 20%. Biochar modified FTCs used as substrate promote denitrification, nitrate nitrogen (NO3− N) mean removal water exceeded 85%. reduced impact electrical conductivity carbon sequestration reached 55.6%. research results will be helpful sequestration, performance treatment effect

Effective Removal of Biogenic Substances Using Natural Treatment Systems for Wastewater for Safer Water Reuse

Water, Год журнала: 2022, Номер 14(23), С. 3977 - 3977

Natural Treatment Systems for Wastewater (NTSW) show great potential economic, socially acceptable and environmentally friendly wastewater treatment, along with the renewal of water its safe reuse. This article presents reduction in nitrogen phosphorus compounds domestic wastewater, which was achieved a 2.5-year operation newly developed NTSW. The presented installation by Institute Applied Ecology Skórzyn (Poland) implemented as pilot plant serving institute building three permanent residents up to five employees. consisted two parts, responsible for: treatment (septic tank compost beds) (denitrification beds, beds activated carbon beds). mean values compound concentrations obtained renewed entire research period were: 0.8, 49.4, 12 3.1 mg/L ammonium (NH4), nitrates (NO3), total phosphates (PO4), respectively. Thus, average reductions 99.6%, 90.9% 94.4% were NH4, PO4, sewage such level, similar drinking water, enables versatile, reuse, situation increasingly limited resources will constitute increasing ecological economic value.

Wetland systems are inexpensive and easy-to-operate wastewater widely used globally at different scales for the safe treatment of wastewater. This study aims to evaluate a pilot-scale vertical flow wetland system treating under loadings. The was constructed using indigenous plants (Imperata cylindrical) operated actual twelve-months. Samples from influent effluent were collected weekly. They analyzed parameters listed in Kuwait Environment Public Authority standards reuse irrigation, such as organic matter, nutrients, heavy metals, microorganisms. results showed that high hydraulic loading rate (1.67 m3/m2.d) phase more efficient than low (1.04 terms organics nutrient removal efficiency. range efficiency matter rates around 48.5-49.0% 59.1-59.1%, respectively. In addition, nutrients 43.7-67.7% 24.7-76.6%, Moreover, metals -134.3-93.8% -1545.7-92.6%, It evident he leaching soil. it found performance closely linked ambient temperature effects during start-up (r = 0.59) 0.43) phases example.
