enhanced performance of crumb rubber filtration for ballast water treatment
Chemosphere, 2009Co-Authors: Zhijian Tang, Michael A Butkus, Yuefeng F XieAbstract:Waste-tire-derived crumb rubber was utilized as filter media to develop an efficient filter for ballast water treatment. In this study, the effects of coagulation, pressure filtration and dual-media (gravity) filtration on the performance of the crumb rubber filtration were investigated. The removal efficiencies of turbidity, phytoplankton and zooplankton, and Head Loss development were monitored during the filtration process. The addition of a coagulant enhanced the removal efficiencies of all targeted matter, but resulted in substantial increase of Head Loss. Pressure filtration increased filtration rates to 220 m3 h−1 m−2 for 8-h operation and improved the zooplankton removal. Dual-media (crumb rubber/sand) gravity filtration also improved the removal efficiencies of phytoplankton and zooplankton over mono-media gravity crumb rubber filtration. However, these filtration techniques alone did not meet the criteria for removing indigenous organisms from ballast water. A combination of filtration and disinfection is suggested for future studies.

crumb rubber filtration a potential technology for ballast water treatment
Marine Environmental Research, 2006Co-Authors: Zhijian Tang, Michael A Butkus, Yuefeng F XieAbstract:The removal of turbidity, particles, phytoplankton and zooplankton in water by crumb rubber filtration was investigated. A substantial reduction was achieved. Of the three variables, filter depth, media size and filtration rate, media size had the most significant influence. Smaller media size favored higher removal efficiency of all targeted matter. There was no apparent relationship between removal efficiency and filter depth. Higher filtration rate resulted in lower removal efficiency and higher Head Loss. Compared with conventional granular media filters, crumb rubber filters required less backwash, and developed lower Head Loss. Consequently crumb rubber filters could be run for a longer time or allow a higher filtration rate. The results also indicate that the crumb rubber filtration alone did not achieve the target removal of invasive species. However, crumb rubber filtration could potentially be used as a primary treatment technology to enhance the efficiency of a secondary treatment process (e.g., disinfection).

Studi & Pengujian Karakteristik Aliran Pada Cussons Friction Loss In Pipe Apparatus & Single Stage Centrifugal Pump Modifikasi penambahan Orifice dan Ball Valve
2017Co-Authors: Sya Bana, Khumaro ElliAbstract:CUSSONS friction Loss in pipe apparatus adalah salah satu perangkat pengujian Head Loss perpipaan yang ada di Laboratorium Mekanika dan Mesin – mesin Fluida. Perangkat ini dilengkapi dengan pompa sentrifugal. Analisa Head Loss meliputi Head Loss mayor dan Head Loss minor. Sistem perpipaan CUSSONS friction Loss in pipe apparatus menggunakan material Polyvinyl Chloride (PVC) pada bingkai dengan dimensi 4,65 m × 0,924 m. Fitting perpipaan terdiri atas long radius elbow 90 , standard radius elbow 90 , elbow 45 , venturimeter, orifice dan valve. Beberapa pressure tap dihubungkan dengan manometer raksa dengan specific gravity (SG) 13,6. Head Loss pipa dianalisia menggunakan formulasi Swamee-Jain dan persamaan Darcy Weisbach. Pompa sentrifugal digerakkan oleh motor sentrifugal singe stage INTERDAB MQC 175. Pengujian menggunakan variasi debit. Modifikasi dilakukan pada pipa III (Line III) dengan penambahan ball valve dengan 3 merk berbeda dan pada pipa II (Line II) penambahan orifice. Dari eksperimen diperoleh grafik hubungan friction factor (f) dan bilangan Reynolds (Re) hasil yang didapatkan menunjukkan bahwa nilai f akan terus menurun seiring peningkatan nilai bilangan Reynolds. Pada pengujian Head Loss minor didapatkan grafik hubungan coefficient minor Losses (K) dan Re pada 3 ball valve berbeda merk, masing – masing fitting. Seiring dengan bertambahnya nilai bilangan Reynolds maka coefficient Losses akan menurun dan selanjutnya nilai mendekati konstan dan pada pengujian orifice didapatkan kurva hubungan Reynolds (Re) dan Coefficient of discharge (Cd). Pada performa pompa, didapatkan Head maksimal pompa 19,95 m. Penelitian dilakukan dengan variasi bilangan Reynolds yang didapatkan dari debit maksimal 62 L/min. Kata Kunci : (Head Loss, bilangan Reynolds , Coefficient of discharge, coefficient Losses, Darcy Weisbach, Single Stage Centrifugal Pump) ================================================================== CUSSONS friction Loss in pipe apparatus is one of the testing device on the piping Head Loss system in the Laboratory of Mechanics and Engineering - Fluid Machinery. The device is equipped with a centrifugal pump. Analysis of Head Loss includes major and minor Head Loss. CUSSONS friction Loss in pipe apparatus piping system uses material Polyvinyl Chloride (PVC) in a frame with the dimensions of 4.65 m × 0.924 m. Fitting in the piping system consists of long radius elbow 90 , standard radius elbow 90 , elbow 45 , venturimeter, orifice and valve. Some pressure tap are connected with the mercury manometer with specific gravity (SG) 13.6. Head Loss of the piping system were analyzed using Swamee’s formulation and Darcy-Weisbach Jain’s equation. This centrifugal pump is driven by a single stage motor, INTERDAB MQC 175. The test uses a variation of the discharge. Modification was carried out on the pipe III (Line III) with the addition of ball valve in three different brands, meanwhile on the second pipe (Line II), there was orifice to be added on to the system. Obtained from the experiment is the correlation of friction factor (f) and Reynolds number (Re) which result the value of f will continue to decline with the increase in the value of the Reynolds number. Head Loss minor testing showed the relevance between coefficient minor Losses (K) and Re at 3 different brands, each fitting. And, along with the rise of Reynolds number, the coefficients are going to fall and much further approaching nearly constant value while the curves of Reynolds (Re) and coefficient of discharge (Cd) can be gained from orifice testing. Pump performance test showed that maximum Head pump was 19.95 m. This research was done by varying Reynolds number that was generated from the maximum discharge 62 L/min.
