“…Effective filtration depends on the volume of the sand filter. The filtration rate of the filter is the key for its proper operation: if the upper layer of sand filter blocks all the particles, the sand filter would rapidly clog [10,[16][17][18].…”

Water covers a large area of the earth that reaches about three quarters of the surface of this planet, but we cannot say that all of this water is fresh or drinkable; according to many statistics, the percentage of fresh water reaches about 1% of the total water on earth. But with the great need for fresh water, whether for drinking or other purposes such as agriculture, the search for water treatment methods has become much larger. One of the most important of these methods that have been developed is desalination of seawater using desalination plants; therefore, we will address here the most important methods used in desalination and water treatment.

“…It works on the same concept as rapid gravity filters; the main difference is that the medium of the filter is contained inside a vessel where water is enforced under pressure through the filter medium. Benefits of gravity filters are [10,12,[16][17][18] as follows:…”

“…Depth filtration involves the removal of constituents in wastewater by passing it through a granular filter bed [13]. In a wastewater treatment plant, depth filtration is commonly used to remove the residual biological floc in settled effluents from secondary treatment before disinfection or discharge to receiving water bodies.…”

This paper presents the concept of check and balance approach in teachıng, learning and assessment processes with the development of a graphical interface tool to solve an advanced wastewater treatment design problem. The developed graphical interface improves the quality of teaching, learning, and the assessment of both, understanding the calculation approaches, as well as understanding the concepts. The tool acts as a calculator or a simulator of a unit converter, population equivalent, designing sewerage systems and selected unit processes of advanced wastewater treatment. A close-ended survey assessment was conducted with a total of 49 respondents who were the registered students for the subject of advanced wastewater treatment. About 79% of respondents agreed that it was hard to score a high mark in the advanced wastewater treatment exam. However, 100% of respondents agreed that the tool could help them to accelerate their understanding of the subject topic. All things considered, the findings of this study show that the developed tool is a potential tool that can aid in the teaching, learning, and assessment processes of any difficult subject that is taught in higher-learning institutions.

“…Considerable research has been done on the eff ect of physical and chemical factors that control the adsorption or attachment of bacteria in the physicochemical fi ltration process. Th e attachment of bacteria to diff erent materials in physicochemical fi lters depends on the media-suspension particle interaction [9]. Arnold et al [10] evaluated the eff ect of cell concentration and fl uid velocity on bacteria attachment in diff erent fabric fi lters.…”

A mechanism to remove Pseudomonas bacteria from contaminated water using textile fi brous media was proposed in this study. The attachment of Pseudomonas bacteria to nylon fi brous media was studied in a laboratory column experiment. A systematic study was carried out to investigate the attachment of bacteria to fi brous material as a function of media mass at a constant solution chemistry. The single-collector contact effi ciency and collision effi ciency from the interaction between bacteria and fi brous media were calculated applying a semi-empirical approach of clean-bed fi ltration theory. The experimental results indicate that removal effi ciency increases with an increase in media mass up to a certain level. This is due to the change in single-collector contact effi ciency and attachment/collision effi ciency, as observed from experimental data regarding removal effi ciency.
