Summary: Heavy metal pollution from industrial wastewaters has a significant impact on soil and cultivated crops. This problem is more common in developing countries like India where untreated industrial wastewaters are often discharged. The findings of this study reveal the negative effects of irrigation with contaminated water on the growth, productivity, and heavy metal accumulation of rice crops.

Summary: The study indicates that brewery effluent has high levels of nitrogen and phosphorus, but the high sodium concentration hinders its reuse in agriculture. By planting salt-tolerant test crops and soil amendments, salt removal efficiency, crop growth, and soil structure can be improved, despite sodium accumulation issues.

Summary: This study assessed the feasibility of continuous hydrogen production in an anaerobic packed bed biofilm reactor (APBR) using paper mill effluent (PME) without any pretreatment or modification. The highest hydrogen concentration achieved was 41.5% at a hydraulic retention time (HRT) of 4 hours. The system showed potential for high hydrogen production rates and yields under different HRTs.

Summary: The newly isolated Bacillus altitudinis SL7 showed efficient degradation of lignin, with optimal conditions at 40 degrees Celsius and pH 8.0. The degradation was confirmed through reductions in color and lignin contents, as well as the emergence of new low molecular weight compounds. The study suggests the potential application of B. altitudinis SL7 in biological treatment of lignin-containing effluents.

Summary: A simple anodization technique was used to synthesize Au doped TiO2 nanotubes electrodes for photoelectrocatalytic degradation of 4-CG. The optimized conditions showed 84% degradation efficiency in 6 hours. The PEC process was more effective compared to PC and EC processes. Additionally, the feasibility of using synthesized Au/TiO2NTs electrodes for large volume wastewater treatment was investigated, showing significant reduction in COD and TOC values. The cost of electrical energy consumption for both batch and recirculation mode treatments was also calculated.

Summary: In this study, a concurrent fixed-bed dual technology was used to remove color from tertiary treated agro-based paper & pulp industry effluent. The prepared Fe-TiO2 composite showed great potential as a durable and efficient catalyst, with 5-10% activity reduction after 50 recycles. The dual process of photocatalysis and photo-Fenton exhibited high color removal efficiency, and the optimal conditions were identified through process optimization. The findings suggest that this innovative technology can be a promising tertiary treatment option for industrial wastewater treatment systems.

Summary: The study found that the hydrothermal carbonization of paper mill sludge (PPMS) resulted in a higher average activation energy for pyrolysis, and the concentration of monocyclic aromatic hydrocarbons in the organic liquid fraction increased with the pyrolysis temperature. The highest yield and highest heating value of the organic liquid fraction were achieved at 550 degrees Celsius, and the pyrolytic chars showed potential for use as a carbon sink.

Summary: This study investigated the impact of POME as a nutrient on microalgal growth and the rate at which nutrients were removed. The results showed that the newly isolated green microalgae C. oleofaciens had a higher growth rate and was able to effectively remove pollutants from POME. This study provides an effective and environmentally friendly method for using microalgae to remove pollutants from POME.

Summary: Recent research interest has focused on developing effective remediation technologies for treated palm oil mill effluent (TPOME). Photocatalytic technology is considered attractive and sustainable, but challenges such as inefficient harvesting of visible/solar light and low remediation efficiency under visible light need to be addressed.

Summary: Farmer-led irrigation development (FLID) has been happening for centuries in all countries where irrigation is practiced, but it is often overlooked by planners and decision-makers in the irrigation sector. However, FLID plays a crucial role in enhancing irrigation development and food security. Although FLID is not explicitly recognized in Kenya's policies and development plans, it is the next big thing pushing the growth of irrigation in the country.

Summary: This paper examines the energy and groundwater irrigation nexus in a highly irrigated ecosystem of north western India. The study reveals that electric tube-wells consume a significant amount of electricity and account for a large proportion of total subsidies disbursed. The area irrigated by tube-wells has significantly increased. Rice and sugarcane crops are the main consumers of energy. The study also shows that the use factor of tube-wells is much higher during kharif season compared to rabi season. Farmers in this region have achieved high economic productivity in all crops except for rice.
