Design of a pre-water filter to provide aeration in filtration process

Occasionally, the tap water of housing area at Gambang, Pahang is detected to have the presence of odour and brownish in colour. The water filter cartridge turns brown rapidly. This issue has harassed the residents and caused doubtfulness by using the water supply. In order to verify this percept...

Sanitary engineering Occasionally, the tap water of housing area at Gambang, Pahang is detected to have the presence of odour and brownish in colour. The water filter cartridge turns brown rapidly. This issue has harassed the residents and caused doubtfulness by using the water supply. In order to verify this perception, tests of colour, turbidity, Biochemical Oxygen Demand (BOD), total solids (TS), total suspended solids (TSS) and total dissolved solids (TDS) were carried out by using the water supply from five houses in Gambang area. The results obtained were compared with the water quality standards. A pre-water filter was designed to solve this problem, which included an aeration and filtration process.

By the completion of pre-water filter design, a running of the water filter was carried out and water after passed through the filter was then tested with colour, turbidity, BOD, TS and TSS amount, along with the confirmation of increased in dissolved oxygen value to ensure the water freshness.

From this research, the final model of the pre-water filter was able to decrease above 50 % of the colour, turbidity, BOD, TS and TDS; and increased the dissolved oxygen level for 5.3 1%. 2014-06 Undergraduates Project Papers NonPeerReviewed application/pdf en http://umpir.ump.edu.my/id/eprint/9772/1/LIM%20JING%20JIN%20%23.PDF Lim, Jing jin (2014) Design of a pre-water filter to provide aeration in filtration process.
