We made two environmental practicals in our first semester. The first one is on sedimentation tank. The objective of this practical is to know the flow profile in the sedimentation tank and to know the performance of sedimentation. The procedure is to calculate the water capacity of the sedimentation tank from its dimension and to find the flow rate required to give an average residence time of 20 minutes. Equations used are V=L*B*D V=Qt The second one is called filterability index. The objective of this practical is to remove suspended matter, rust, sludge, scale or algae from wastewater and to know other hazards may exist in the handling of biocides used to disinfect the water. There are four procedures to calculate. First procedure: The use of deep beds of porous granular media to filter liquids to improve their clarity is wideapread in municipal and industrial practice. Second procedure: Predominant is the filtration of drinking water and industrial water although the filtration of sewage as a tertiary stage of treatment is increasing. Third procedure: The filterability index apparatus utilized a bed of granular material normally sand but which can be chosen by the investigator. Fourth procedure: The measurements taken with this apparatus enable a filterability number to be calculator which has significant in deep bed filter performance. Equation used is F=HC/VCₒt |

Hey Thawdar.
I hope you are great and thank you for this experimental report!
I looks like your experiment went well. I like how the these practicals help us understand how to take issues like suspended particles in water and the pathogens lying in water
Thank you for reporting!
Stay blessed and,
Warm regards,
Rosa

Hello Thawdar
I do hope that you are fine and doing great with your works.
Thank you for your report about environmental practicals. I would like to wish you all the best for your studies.
Green Cheers from Nepal :)
Keep writing great reports.
We are eager to read more reports from you.

Hello Thawdar. And thank you for this experimental report.
It shows how we can use science, particularly physics, mathematics, as tools and support to help understand environmental issues. We should encourage the use of those fields in our educational systems to promote the protection of the environment.
Once again thank you and take care.
Best regards!
