Abstract:

A plasmonic metal-insulator-metal waveguide filter consisting of one rectangular cavity and three silver baffles is numerically investigated using the finite element method and theoretically described by the cavity resonance mode theory. The proposed structure shows a simple shape with a small number of structural parameters that can function as a plasmonic sensor with a filter property, high sensitivity and figure of merit, and wide bandgap. Simulation results demonstrate that a cavity with three silver baffles could significantly affect the resonance condition and remarkably enhance the sens

The study covers different investigations related to the upgrading of a post-treatment system for the effluent from a upflow anaerobic sludge blanket reactor. The original post-treatment scheme comprised three ponds in series and a small coarse rock filter inserted in the last pond.

The system was conceived for 250 population equivalents, occupied an area of only 1.5 m2/inhabitant and aimed at very good removals of all major wa

Studies of influence of the main structural elements on the filtration processes of nickel melts during casting in a vacuum induction installation were carried out on low-temperature physical models. Modeling of melt filtration processes is based on the hydrodynamic similarity of the processes of motion of melt flows and nonmetallic inclusions in casting tanks.

After seeding with residual sludge from a municipal wastewater treatment facility, the start-up of the ABR and SBR was accomplished in one month. During a steady running period, the ABR + SBR process showed stable performance in treating WORS.

An ABR with a circular additional filter at the outlet pipe was constructed to treat wastewater from a residential colony of 108 households with an average inflow of 110 m3/day and a nominal hydraulic retention time (HRT) of 20 h. Analysis of the chemical oxygen demand (COD), total nitrogen, sulfate and phosphate load, and total coliform removal for

Abstract:

Together with atmospheric and water pollution, noise pollution is threatening human society with vehicles constituting the major source of noise. The available literature on control measures (1, 2, 3) indicates purely reactive mufflers in general are of more use for fixed speed machinery and dissipative attenuators have the ability to filler out acoustic energies over a wide range of frequencies. This paper presents cm attempt made to use a combination of these major types of mufflers fitted in the exhaust line of a four stroke, twin cylinder stationary diesel engine to attenuate exhaust noise

Sangkrah merupakan kampung perkotaan yang padat dan kumuh yang memiliki sanitasi lingkungan yang buruk. Untuk memenuhi kebutuhan buang air besar masyarakat biasanya menggunakan sarana WC umum karena hanya sedikit warga yang memiliki km/wc. Saat ini Kampung Sangkrah telah menggunakan Sanimas (sanitasi berbasis masyarakat) sebagai lokasi percontohan pengelolaan sanitasi lingkungan yang buruk. Lokasi MCK berada di lokasi yang masyarakatnya bersedia untuk berpartisipasi dalam pembangunan Sanimas. Penelitian ini bertujuan untuk mengkaji sanitasi ekologis yang diterapkan pada IPAL Sanimas dan sebera

Abstract:

Household type Johkasous which have a flow stabilization function were surveyed on their performance. The water level, flow velocity and SS were measured after the maximum flow entering the anaerobic filter chamber with or without flow stabilization operation. In operation without the flow stabilization, the flow peak directly reached the biofiltration chamber and the flow rate kept at 1 cm/sec during 3–4 min in the connection baffle between the two anaerobic chambers. This suggested the possibility of sludge transfer from the first anaerobic chamber. Moreover the increase of SS in the second

Abstract:

The necessity of two-stage (multi-cyclone-baffle) inlet air filters used for motor vehicle engines operating under dusty conditions was demonstrated. The advantages of a set of several dozen cyclones (multi-cyclone) used for filtering inlet air in the engines were shown. The problem of dust accumulation separated by the cyclones in the multi-cyclone dust collector and the necessity of its removal on a current basis were analyzed. Methods of removing dust from the dust collector by means of the QS suction flow were described. It was demonstrated that the most rational method of forcing the suct

Abstract This study evaluated the effects of irrigation water management techniques on the growth and yield parameters of madumbe (Colocasia esculenta) irrigated with anaerobic filter (AF) effluent. The irrigation water management treatments considered were alternate wetting and drying (AWD), continuous flooding irrigation (CFI) and wetting without flooding (WWF). It was hypothesized that irrigation techniques with anaerobic baffled reactor (ABR) effluent have a significant effect on the growth and yield of madumbe. The effects of the treatments were significant (P &lt; 0.05) on the number

Abstract:

Abstract The research developed a combined system in batch flow and in pilot scale for the treatment and reuse of urban effluents. The system was fed raw effluent from a university campus in Brazil and composed of four anaerobic reactors, three constructed wetlands (CWs) and an ozonation unit. The three sequential hybrid constructed wetlands were composed of a floating treatment wetland, an aerobic-anoxic baffled constructed wetland (CW) and a saturated vertifcal flow CW. Later, during the last trimester, weekly samples of the treated effluent were ozonated by bubbling with an application rate

Abstract:

In this paper, Cost-effectiveness of various straw pulp wastewater treatment technologies were compared in detail, moreover the separate and combined process of Coagulation Sedimentation, Anaerobic Baffled Reactor, Sequencing Batch Reactor and Biological Aerated Filter processes were researched. The test result has showed that when addition dosage of PAM and PAC is 4mg/L and 80mg/L in Coagulation Sedimentation separately, and ABR HRT is 10h, the biodegradability of the straw wastewater increased from 0.25 after pretreatment to about 0.45. As the best SBR HRT is 8h, the CODcr removal rate was a
