This was due to the low cation release from the wood biomass in both metal solutions, resulting in a very low cation exchange rate. However, when using Fucus vesiculosus algal biomass as a biosorbent, the removal efficiencies were much higher, with 67% and 55% for copper and zinc ions, ...
Domestic hot water is either heated by solar collectors during periods when there are significant levels of solar radiation (generally during summer), or by using a heat pump (see Figure 15.12). Sign in to download full-size image FIGURE 15.12. Solar vacuum panels on the passive office buildin...
Preheated water active and waste heat recovery solar stills During the sunshine hours, the hot wastewater could be recirculated in order to recover the wastewater heat. Such recovery is carried out through passing wastewater at a constant flow rate and hence the basin is preheated. This methodolo...
Producers of food products that need to be rehydrated before consumption should be aware of the safety of water used for this purpose. In particular products that will not, or not sufficiently, be reheated need attention from both the water supplier and the supplier of the dried food. The ...
Mung bean starch (MBS)-based edible films with incorporation of guar gum (GG) and sunflower seed oil (SSO) were developed in this study. MBS, GG, and SSO were used as the main filmogenic biopolymer, thickener, and hydrophobicity-imparting substance, resp
(DI) water heated to 100 °C temperature and subjected to 8 MPa pressure in a laboratory reactor for 72 hours to simulate shale softening. The low-temperature nitrogen adsorption and density measurements were performed on the original and treated shale to determine the changes in micro and ...
However, when the fluid on the hot side was a LiBr solution, the heat transfer rate decreased. In addition, the heat transfer rate decreased as the LiBr concentration increased, and the heat transfer rate was lowest when the concentration was 62%. At a mass flow rate of 200 kg/h, as...
itself due to corrosion or damage may show up as a puddle on the floor or as wet insulation that steams when the heater is being heated. Leaks can occur at connecting piping fittings on or around the indirect water heater or calorifier such as where cold inlet or hot water outlet buildi...
When the modified solar distiller was combined with an outdoor solar heater, it boosted distillation water production by 292% [22]. Another study investigated the integration of a vacuum tube solar heater with a solar distiller, both experimentally and theoretically, using Turkish climatic conditions...
However, for a water heater that is indirectly heated (e.g. with a separate boiler), the source side can be used to provide remotely heated water to the tank. The source side is configured to operate as a component on the demand side of a plant loop. The design flow rate through the...
