Filters are essential components for maintaining the stability of drip irrigation systems, effectively reducing risk clogging. However, when applied to slurry complexity water quality makes it unclear how different filter types and their combinations affect hydraulic performance system. This study provides a comprehensive evaluation two common combinations, considering various flow rates biogas slurry-to-water ratios under conditions. The results revealed following key findings: (1) In application irrigation, an increase in concentration or rate significantly affects filter, increasing clogging shortening operational lifespan. Notably, impact changes on is much greater than that rate. Compared mesh filters, disk filters offer better performance, with contaminant capacity being approximately three times filters. (2) combination generally outperforms single terms removal capacity. Due unique nature source slurry, selection process was conducted. It found used as pre-filter post-filter, overall head loss change smallest, uniformity least. (3) entropy weight-TOPSIS evaluation, filter’s operating time factors affecting its performance. From perspective improving system, recommended use + combination. conducts practical measurements capacity, filtration accuracy, other indicators commonly aiming provide useful references

Abstract The industrial development of a country plays vital role in its overall progress and is closely tied to capacity electricity generation. However, the scarcity natural resources increasing costs fuel global markets pose significant challenges for developing countries like Bangladesh managing rising expenses Consequently, government exploring alternative energy such as solar, wind, hydroelectricity, biomass, biogas supplement fossil fuels optimize generation cost. This paper aims provide comprehensive overview current status resources, including gas, coal, oil, which are conventionally used Bangladesh. It highlights concerns about dwindling resource availability their impact on country's landscape. Through numerical analysis, it demonstrates detrimental effects relying heavily gas‐based power plants, leading supply instability. To address ongoing crisis, proposes adoption renewable sources viable solution. Additionally, also acknowledges associated with implementing large‐scale projects distinct areas country, limited infrastructure, technical constraints, need investment. Overcoming these barriers crucial achieving widespread utilization resources. concludes by offering recommendations overcome maximize contributions meeting future demands. suggestions include robust policy reforms attract investment, emphasizing research development, promoting community engagement initiatives. potential shaping more secure sustainable Bangladesh, importance socio‐economic development.

Biogas slurry (BS), waste water of energy production, holds potential as both an irrigation resource and a liquid fertilizer source. Typically combined with mineral at specific ratios, BS is applied in fields drip systems to enhance crop growth. However, the soil infiltration process remains poorly understood, mainly owing BS's differing characteristics from conventional sources. This study investigated morphological characteristics, transport distribution three ratios BS-water using column experiment, post-irrigation surface pores elements analyzed electron microscopy spectrum scanning techniques. The findings reveal that significantly alters compared morphology wetting-front changed nearly "hemispherical" "half-pear" shape time irrigation. soil-wetting front's vertical distance was notably smaller, approximately 50% depth seen traditional source irrigation, even after redistribution moisture, it still difficult reach main root zone most crops. Moreover, carbon content on increased, ranging between 19.05–47.62% scenario, which led pore blockage decrease porosity 11.99–40.5%. dynamic viscosity higher than CF.Theses indicate effect affects infiltration.In conclusion, this paper proposes model integrated agronomic measures mitigate adverse effects caused by changes transportation distribution.

Excessive heavy metal content in soil can seriously hinder plant physiological metabolism and growth. This study, with soybean, examined how drip irrigation reduced toxicity. The experiments four frequencies were conducted by controlling the lower limit of matric potential (D1: −10 kPa; D2: −20 D3: −30 D4: −40 kPa). Through comparison traditional surface irrigation, effects on distribution, soybean growth status, transcriptome under Cd, Pb Cr(VI) composite pollution comprehensively analyzed. results show that (i) Cr(IV) migrated away from thereby reducing inhibition stress at root, among which D1 had best improvement effect (ii) Drip improved resistance to stress, promoted transport fixation free Cd2+, Pb2+ Cr6+ cells, damage oxidative ions cell structure. (iii) was conducive energy supply protein stability metabolism, helped activity. Overall, compared toxicity metals soybeans moving out root zone enhancing this study provide a theoretical basis for application technology prevention control pollution, new strategy safe production agriculture.

The cultivation of corn holds immense importance as a foundational global grain crop, catering to human sustenance and serving vital animal feed. Moreover, plays substantial role in biofuel production. Additionally, cultivating can have positive effect on crop rotation by improving soil quality reducing erosion. In pot trial using six distinct compost variations derived from different organic wastes fertilizers for GS210 corn, specific indices, such Fv/Fm (0.80, 0.80, 0.81), Fv/F0 (4.07, 3.99, 4.03), PI (4.62, 4.22, 5.21), RC/ABS (1.71, 1.68, 2.01), exhibited the highest values. Interestingly, mineral fertilization with NPK displayed significant benefits various growth parameters like plant height (188.9 cm), cob length (17.50 grains per (324.0), thousand-grain weight (MTZ) (285.2). difference count between control reached 168.5 grains, which was statistically confirmed. Furthermore, grain’s protein content notably increased (9.5) compared (8.5). While showed lower outcomes (9.1–9.3) than fertilization, they generally outperformed This prompts need future studies assess effectiveness individual combination nitrogen fertilization.
