Tank color impacts marine fish larval performance, as dark tanks appear to provide contrast that allows larvae to better visualize live and artificial prey. While tanks can be fabricated in any color, commercially available on–growing systems are generally black, green, or dark and light blue. Anecdotal information suggested that certain juvenile fish perform better in tanks with black sides an...

Phase change material (PCM) water tanks have a major influence on the efficiency improvement of solar energy systems. This article discusses effects PCM under various inlets in tank based related research. So as to research performance storage tank, this paper built set experimental systems using sodium acetate trihydrate. The thermal characteristics two different were analyzed at 2, 6 and 10 L...

Energy use in water supply systems represents a significant portion of the global energy consumption. The electricity consumption due to the water pumping represents the highest proportion of the energy costs in these systems. This paper presents several comparative studies of energy efficiency in water distribution systems considering distinct configurations of the networks and also considers ...

Onsite sanitation with septic tanks is popular in most of the Asian countries. The case study conducted in Hanoi and suburban area of Bangkok indicates that the septic tanks employed did not perform as required. The septic tanks just convert the suspended pollutants into dissolved form and release them to the environment due to insufficient maintenance. Thus the effluent from the septic tank is...

Recently, a great amount of interest has been shown in the field of modeling and controlling hybrid systems. One of the efficient and common methods in this area utilizes the mixed logicaldynamical (MLD) systems in the modeling. In this method, the system constraints are transformed into mixed-integer inequalities by defining some logic statements. In this paper, a system containing three tanks...

The Chinese Bohai Sea is a semi-enclosed, highly vulnerable continental sea that exposed to the risk of oil spills due offshore and gas activities. In this study, geographic information system (GIS)-based “tanks–pipelines–platforms–ships–channels” (TPPSC) comprehensive framework, including storage tank indicator, pipeline platform ship channel was built analyze marine spill in show spatial diff...

a large settling tank. There are five such tanks. They are connected with one another and a constant level is maintained in all. The capacity of each tank is 1.2 million gallons; the total capacity being 6 million gallons. The daily draw is about 2 million gallons. Hence theoretically the water settles for about 3 days before entering the Paterson filters. The engineer in charge, however, state...

The acoustic emission (AE) technology can be used to assess the security condition of oil storage tank without opening pot. Signal recognition is a foundation to analyze the corrosion status for oil storage tanks. Because of inadequateness of the analysis method of parameters, a new acoustic emission signal recognition method is proposed based on wavelet transform and RBF neural network. AE sig...

Packed-bed single-tank thermocline system with reduced cost is an alternative to the conventional two-tank for thermal energy storage. This work systematically explores wall impact on behavior of packed-bed tanks. For this purpose, adapted transient models were developed and fully exploited first time. Two tank configurations investigated compared: a high-temperature pilot-scale steel low-tempe...
