Efektivitas Pengolahan Air Limbah Domestik Grey Water Dengan Proses Biofilter Anaerob dan Biofilter Aerob (Studi Kasus: IPAL INBIS Permata Bunda, Bontang)

Analisis dan Perancangan Wireless Roaming (Studi Kasus Universitas Baturaja)

Wireless roaming is one way to improve the reliability of a network of hotspots that are still using the topology Basic Service Set (BSS). When the user walks away from one access point (AP) or one AP die then begins to lose the signal, the mobile station (MS) is automatically connected with the AP to another without reconfiguring. Devices that support wireless roaming is the AP TP-Link TL-WR74...

Livestock Air Treatment Using Pva‐coated Powdered Activated Carbon Biofilter

This study evaluated the efficacy of polyvinyl alcohol (PVA)‐coated powdered activated carbon particles as a biofiltration medium. This material exhibited excellent properties as a biofiltration medium with a water holding capacity of 1.39 g H2O/g‐dry PVA; wet porosity of 0.53; and significantly lower pressure drop than that of commonly reported biofilter media such as compost. Bench‐scale biof...

Hydrodynamic characterization of a trickle bed air biofilter

This paper reports the effect of superficial liquid mass flow rate and bed void fraction on the pressure drop, dynamic liquid hold-up, mean liquid residence time and biofilm wetting, in a co-current down-flow xylene-removing trickle bed air biofilter (TBAB). The gas–liquid pressure drop increased with liquid mass flow rate and it also increased with diminishing bed void fraction, the effect bei...
