The pollution of water bodies due to the discharge of effluents without treatment is a global problem. Therefore, different technologies have been implemented for the removal of contaminants from wastewater before the final disposition. Among them, adsorption processes using residual biomasses are becoming very popular due to the low cost and high availability of adsorbents. Thus, in the present work, the synthesis of modified biochar from agro-industrial residues derived from the wheat-processing industry, as a valorization alternative of these residues, for its use in the removal of Cr (VI) and methylene blue (MB) has been analyzed. The biochar was prepared using a ramp function of 5 °C/min until 250 °C for 30 min. The adsorption tests were developed in a batch system, using 30 mg of adsorbent in 10 mL of solution. From SEM analysis, the formation of tubular cavities and porous structure was seen, caused by the basic hydrolysis with KOH. From adsorption tests, an adsorption capacity of 12.98 mg/g and 97.38% of efficiency for MB at pH 10 was noted, while for Cr (VI), it was 11.35 mg/g and 85.15% at pH 2. Freundlich’s model adjusted the adsorption equilibrium data with R2 > 0.9. The maximum adsorption capacities in the monolayer were 186,375 mg/g and 90.723 mg/g for Cr (VI) and MB, according to Langmuir’s model. From a kinetic study, it can be said that the process occurs by chemisorption through electrostatic interaction and ionic interchange between adsorbate and adsorbent.

“…Local farmers in Pakistan have domesticated goshawks to drive away crows, sparrows and other birds from farmland [3]. In 2020, Punjab University analysed the birds in the Indus River basin in southern Lahore and found 223 species of birds, among which the most abundant species are crows, sparrows, common three crested birds and common starlings [4]. The house crow is found to be one of the main local birds in Punjab Province, India, adjacent to Punjab Province, Pakistan [5].…”

Converter station refers to the station established in the HVDC transmission system to complete the conversion from AC to DC or DC to AC and meet the requirements of power system for safety, stability and power quality. Unlike AC substations, bird damage is more frequent due to its DC characteristics. Especially for high-voltage converter stations, the blackout caused by bird damage will cause more serious economic losses and social impact. Therefore, Pakistan ± 660kV Matiari-Lahore HVDC transmission project has been selected as the research object in this paper. Through the analysis of bird habits, four targeted bird prevention measures have been proposed and installed in the converter station for verification. The test results show that the proposed anti-bird damage measures can effectively reduce the number of bird damage trips and ensure the safe operation of the converter station.
