In industrial applications, 90-150°C hot water needed during production processes is traditionally provided by fuelfired boilers. The use of fuel-fired boiler has a low efficiency of energy usage and potential danger of explosion. Byproduced 30-60°Cwaste water with large amount of energy is rejected to environment directly, which causes a great energy loss and thermal pollution. Seeking for a h...

Arsenicosis is a serious environmental chemical disease in China mainly caused by drinking water from pump wells contaminated by high levels of arsenic. Chronic exposure of humans to high concentrations of arsenic in drinking water is associated with skin lesions, peripheral vascular disease, hypertension, blackfoot disease, and high risk of cancers. Lead by the Ministry of Health of China, we ...

Autonomous photovoltaic panels are intermittent sustainable energy sources which require energy storage to balance generation and demand, as photovoltaic generation is time and weather dependent. Traditionally batteries are the most common storage technology for photovoltaic systems. Photovoltaic batteries can encounter extended periods of low State of Charge (SOC), resulting in sulphation and ...

abstract: impeller trimming is a proper way to alter the performance of centrifugal pump with a constant speed so as to meet the demand on the specified flow rate and head in pumping systems. the affinity law accounting for the impeller trimming is the key relation to determine the pump performance with a trimmed impeller. there seems no experimental study dealing with such an affinity law for ...

Abstract Water is an essential resource for agriculture and the majority of land irrigated through borewells or wells. The power requirement irrigation pump motor fed by on-grid supply but availability electricity in rural areas still questionable. With rising concerns about global warming rise carbon footprints, it necessary to choose clean green energy, thereby attaining self-sustainable life...

Photovoltaic based reverse osmosis desalination systems (PV/RO) present an effective method of water desalination especially in remote areas. The increase of the feed water temperature leads to an amelioration of the plant performances. Photovoltaic Thermal Collector (PV/T) represents an ideal power source as it provides both electric and thermal energies for the reverse osmosis process. Nevert...

Hybrid photovoltaic-thermal heat pump (PV/T-HP) solar energy systems are promising since they can achieve a system total efficiency greater than 80%. By maximizing the output of PV/T for simultaneous heating and cooling, this strategy meet over 60% urban households’ needs around 40% their cooling needs. In work, novel evaporator was designed, fabricated, an aluminium foil encapsulated hydrated ...

Automated water pump systems are becoming increasingly important as they can regulate pumps based on current data and conditions, reducing energy use waste while ensuring efficient distribution. Research shows that automated have several advantages over traditional manual systems, including increased efficiency, lower consumption, better management, improved performance. However, there also som...

The objective of this research study was to design and implement a water treatment system using ultraviolet radiation (UV) produced with photovoltaic panels. This would be able satisfy the needs residents who do not have drinking live in rural areas. begins evaluation energy demand required for light lamp pump, which are powered by panel. consists tank collection, 0.5 HP pre-filter filter sedim...

1 Description of the Model We consider a model of a water level control system extended from the one of Alur et al. [1] and our previous paper [4]. In particular, we use this case study to demonstrate the influence which different abstractions of the same continuous stochastic command have. The abstraction of a guarded command with a continuous probability distribution into one with a discrete ...
