“…From Equation (4) it is found that volume of SS entering a tidal basin (VSS) depends on SSC, Discharge, time and density of fine sediments and SSC remains a major driving force of TRM outcome as all the other parameters can be controlled. Observations show that at a constant shear stress in saline water, the value of SSC increases with a reduction in flow depth and vice versa [29]. Furthermore, increase in discharge per unit area increases the value of SSC [30].…”

The south west coastal zone of Bangladesh has been affected by rampant water logging due to vulnerable climate, silted rivers and stumpy terrain; and introduction of IWRM and TRM at some places of the zone has substantially safeguarded the circumstance. This study aims to assess the benefits achieved due to implementation of IWRM in parts of Khulna and Jessore districts, and investigate some technical aspects evolving TRM. Analyses have been carried out using satellite images, RS and GIS technology, Digital Elevation Model (DEM) and field investigations. A mathematical formulation has been made to assess rate of tidal sedimentation due to TRM and selection strategies of tidal basins. The study comes up with evidences of considerable advancements in regional livelihood i.e. flood resistance, cultivated lands, cultivable area, cropping intensities and food security due to IWRM. Moreover, the technical facts established on TRM would help planners to have vivid perception regarding the process.

“…González-Leos [23] found that lactic acid could be obtained from sugarcane bagasse hydrolisates, fermented with Lactobacillus pentosus, obtaining up to 55.437 g•L −1 of lactic acid. Moreover, Soltanian et al [24] presented a survey to investigate a lignocellulosic-based sugarcane biorefinery with cogeneration of lactic acid and power. The 20.49% of the total cost of the biorefinery was due to the lactic acid synthesis unit.…”

This study explores the use of natural, ecological coagulant-flocculants to reduce suspended particles in water. Three compounds were tested, namely: diatomaceous earth, calcium lactate and lactic acid. For this purpose, experiments in jar tests were carried out and the best compound was submitted to an optimization in order to evaluate the most significant parameters affecting its use as coagulant-flocculant. First results evidenced that lactic acid remove 71% of the suspended particles during the first five minutes, and up to 83% during the first 15 min. To optimize its use, the range of suspended particles concentration, lactic acid dose and salinity gradient was tested by means of an incomplete 33 factorial design. This technique allows reducing the number of experiments to be carried out through a response surface methodology, which enables to infer the values of the dependent variables in not studied situations, by means of predictive equations. As a result of the experiments carried out, optimal conditions to remove suspended particles were set at a lactic acid concentration of 1.75 g·L−1. As lactic acid may be obtained biotechnologically from organic wastes, this use supposes a promising area by keeping products and materials in use and contributing to a circular economy.
