Emitter clogging is a major challenge for phosphorus drip irrigation systems (PDIS). Calcium ions (Ca2+) play an important role in PDIS clogging. However, the effects of Ca2+ and fertilizer interactions on emitter are largely unknown. This study investigated behaviors with four concentrations (25, 50, 100, 200 mg L−1) three application strategies (no-fertilization, urea phosphate, mono-ammonium phosphate). Results show that concentrations, phosphorous fertilizer, their interaction...
The presence of oxygen vacancies can promote the formation active species, which is essential for phenol oxidation.
High sediment content in irrigation water is a common challenge agricultural regions, leading to increased clogging of emitters and reduced system efficiency. Lateral flushing (LF) an effective measure reduce emitter for drip systems. However, the effect LF on with high different types remains largely unknown. Thus effects 8 flat (FE), 3 cylindrical (CE), single wing labyrinth (SL) 2 inlaid strip (SE) were evaluated. The degree fluctuation values was 5.4–25.6% higher non-flushed lines...
The self-reactivated δ-MnO<sub>2</sub> catalyst was developed, and showed high activity stability for the CWAO of phenol at a very low temperature.
Strong metal–support interactions involving electron and oxygen transfer in Pd/C (no leaching but less active) Pd/CeO2 (active leaching) catalysts determine their catalytic performance the wet air oxidation of amide. To control these two types interactions, triple-layer structure Pd/CeO2/C, where Pd is predominantly located on CeO2 a C support, was designed prepared. As result, electrons could be transferred from carbon to via for excellent resistance, while high activity. In addition, both...
Surface properties of nanoceria can strongly affect the catalytic performance in oxidation reactions. In this work, a simple but efficient post-treatment, where H2O2 is used as complexing agent to dissolve Ce3+ from surface CeO2 nanorods with help ultrasonic treatment, carried out tune and increase their for wet air (CWAO) phenol. It found that dissolution create more defects result much rougher surface. The H2O2–ultrasonic treatment also concentration, oxygen vacancies, narrow band gap...
The inevitable inorganic fouling in saline water drip irrigation systems (SWDIS) with phosphorus fertilizer has become key obstacle for utilizing and phosphate fertilizer. This study developed a greener anti-fouling method by intelligently applying superior (i.e. ammonium polyphosphate, APP). X-ray diffractions Rietveld refinement were used to determine the mineral composition cell parameters of scales. Results showed that APP effectively minimized SWDIS, fixed scales quantity reduced...
Saline-alkali soil is a major threat to global food security. Phosphorus (P) fertilizer essential for crop growth and yield production. Nevertheless, the optimal phosphate application rates summer maize under coastal saline–alkali are still unclear. A field experiment with five (0, 45, 90, 135, 180 kg ha−1, referred as T1, T2, T3, T4, T5, respectively) was conducted during 2018–2020 seasons study effects of on grain yield, biomass, nitrogen (N), P potassium (K) accumulation, N, P, K...
Iron is one of the essential elements for crop growth. Traditional iron fertilizer application method by injecting into soil results in low utilization efficiency and a considerable amount residue soil. Applying drip irrigation system could effectively improve fertilizer. However, emitter clogging seriously restrict this technology. Here, effects different types fertilizers [Ferrous sulfate (FeSO4); Ferric citrate (FC-Fe); Sodium ferric ethylenediamine tetraacetate (EDTA-Fe); And no (CK)] on...
Reusing reclaimed water through drip irrigation offers an effective way to overcome freshwater scarcity. However, biofilm accumulation in the flow channel of emitters is primary obstacle. So far, development remains largely unknown. Here, industrial computed tomography was used quantify emitter developments. Results showed that typically accumulated inlet and decreased toward direction. Biofilm also dead areas having low velocities, such as edge, corner, adjacent surface zones channels. The...
Emitter clogging is a major obstacle to the application of brackish water in drip irrigation systems, which can be aggravated with inappropriate fertilizer application. Among element fertilizers, nitrogen and phosphorus (NP) trigger higher risk clogging. However, effect selection different types NP compound fertilizers on emitter remain unknown. This study investigated effects no (CK), two industrial grade monoammonium phosphate (I_MAP) diammonium (I_DAP), agricultural (A_MAP) (A_DAP), new...
Abstract The surface structure and catalytic properties of Pt–Ru bimetallic catalysts with identical bulk composition can be continuously tuned by treatment at different temperatures. activity these in CO oxidation was positively related to the temperature, but opposite trend observed for solvent‐free benzyl alcohol. It found that migration Pt occurred when temperature increased. During this process, nanoparticles changed from a Ru‐rich Pt‐rich surface. electronic interactions between Ru...
Pressure compensating emitters (PCE) can maintain a consistent irrigation flow rate under varying pressures through its internal compensation diaphragm and effectively improve the uniformity of drip systems. However, PCE function is prone to failure, particularly when using marginal water, which cause various technical economic problems. To date, little known about failure behavior PCE. This study investigated effects three (0.1Mpa, 0.2Mpa, 0.3Mpa) on Then dynamic changes in clogging...
The utilization of brackish water has emerged as a promising solution to mitigate scarcity. However, fouling presents significant technical and economic challenges distribution systems (BWDS). Manganese (Mn2+) copper (Cu2+) are among the ions commonly present in water, but their impacts on BWDS remain largely unknown. This study investigated effects four concentrations Mn2+ (0.05, 0.5, 1.5, 3.0 mg L-1) Cu2+ (0.02, 0.2, 0.6, 1.2 behavior within BWDS. results revealed that higher significantly...
