“…The process reduced the pH by 26%, the decrease may be due to chemical reactions influenced by a functional group of any filtration medium. Additionally, during adsorption (Vader Waal forces of attraction) there is the possibility of cations and anions being released into the system, keeping pH in the range (Tusiime et al, 2022). The values obtained are in agreement with results reported before, which adsorption occurs in pH range of 6.…”

Water pollution is a global problem that can be a threat to the environment and human health, which is why efficient technologies are required for the treatment and comprehensive management of residues from wastewater treatment. In this sense, the present study used different filtration media such as zeolite, pumicite, tezontle, dolomite, ground corn straw, coconut fiber and biocalcium to analyze the physical-chemical interaction of these materials and the components of graywater from laundry in a simple filtering process. Four filter columns with different bed layers, same graywater and a filtration rate established by each filter were installed and operated at laboratory scale and in parallel. The pollution reduction was from 70.2% - 98% for selected parameters (COD, TSS, TDS, PO4 and NO3) in filter columns. Thus, filters with different arrangement of unconventional filtration media are efficient in purifying greywater.

Engineering and Architecture in the northern part of the State of Mexico” aims to disseminate works in the areas of Engineering (Electronics, Mechanics, Chemistry and Materials) and architecture, generated by academics from the Tecnológico de Estudios Superiores de Jocotitlan. As in all higher education institutions, the documentation and publication of the most outstanding results of recent work that are the result of the natural and daily work of academic life, are part of the continuous work that is carried out, in addition to the already so well-known teaching. Student participation is reflected in the presence of their authorship in several chapters that are integrated into this Handbook; supporting the professional training of those who are the origin of education. It can also be mentioned that the participation of collegiate bodies, identified as professors with a PRODEP profile and members of academic bodies within this Handbook, allows contributing to the institutional strengthening of the Tecnológico de Estudios Superiores de Jocotitlán. The content is intended for general and technical reading by anyone who is interested in the topic and also by those who can learn what this technology produces for the educational, industrial and research sectors.

“…We have attained a 94% BOD5 removal efficiency with aeration and media filtration at a HLR of 10 m/h and 98% at 60 m/h (Table 6). These results are in line with those reported by [30], where they achieved BOD removal rates of 98.8%, 99.5%, and 98.9% using sand and charcoal media at hydraulic retention times of 12 h, 24 h, and 36 h, respectively.…”

“…With media filtration we obtained 80.3% and 63.5% removal efficiency of BOD5 and COD (Table 6). We achieved 93% BOD5 removal at HLR 10 m/h and 96% at 60 m/h by aeration and sand media (Table 6), similar to [30] findings of 96.5%, 99.1%, and 96.8% BOD5 removal using sand media at different retention times. However, it is important to note that their influent BOD5 was 1.6 times lower than our raw water BOD5.…”

“…Overall Total-P removal with aeration and media filtration was 59% and 76%. In their study [30], attained Total-P removal rates of 43.6%, 34.5%, and 33.6% at hydraulic retention times (HRTs) of 24, 36, and 48 hours, respectively, using sand media, while our filters showed comparable results when the influent Total-P ranged from 9 ± 4.9. The chemical characteristics of both untreated and treated sewage water samples were examined to assess their appropriateness for irrigation.…”

The study investigated the potential of sand and activated charcoal filtration systems to enhance water quality for irrigation by treating aerated sewage effluent from. Setup involved a 60 cm deep sand filter connected as the inlet to another 30 cm deep sand filter and this filter linked as the inlet to a 30 cm deep charcoal filter. These filters were operated in series at hydraulic loading rates (HLR) of 60 m/h and 10 m/h. Notably, operating the filters in series at an HLR of 10 m/h yielded superior effluent water quality compared to an HLR of 60 m/h. System achieved significant removal efficiencies for turbidity, BOD5, COD, Total Nitrogen (Total-N), Total Phosphorous (Total-P) with 71.9%, 54.4%, 71.9%, 44.4%, 39.1%, and 42.9% with a 90 cm deep sand filter at an HLR of 10 m/h, and also with a combination of sand and charcoal filters at an HLR of 25 m/h system achieved 81.6%, 80.3%, 63.5%, 47.5%, and 64.3% respectively. We also examined the chemical characteristics of both untreated and treated sewage water samples, revealing a hierarchy of cation and anion prevalence as follows: Na+ > Ca2+ > Mg2+ > K+ for cations, and Cl- > HCO3- > SO42- > CO32- for anions. Our study demonstrates that the combination of aeration and sand filtration effectively ensures safety by preventing water body pollution and unpleasant odours with high-quality treated wastewater suitable for sustainable agricultural use.
