Batch reverse osmosis (RO) is a promising approach to high-recovery desalination. It has low energy consumption, but system size increases sharply with recovery because of the need for large work exchange vessel. In this study, we propose compact hybrid batch/semi-batch (HBSRO) incorporating aspects each approach. HBSRO works in three phases, i.e. semi-batch pressurisation phase, batch and fina...

One of the essential factors for selection drying process is energy consumption. This study intended to optimize treatment capers using convection (CD), refractive window (RWD), and vacuum (VD) combined with ultrasonic pretreatment by a comparative approach among artificial neural networks (ANN) response surface methodology (RSM) focusing on specific consumption (SEC). For this purpose, effects...

To control the quality of reverse osmosis (RO) product water and reduce operational costs and environmental impacts by increasing the system’s energy efficiency, it is necessary to identify the influence of process parameters on energy consumption and permeate water quality. This paper introduces a case study focused on the application of Design of Experiments (DOE) method in an industrial-scal...

Wireless sensor nodes working together in the same environment cooperatively is called Wireless Sensor Network (WSN). WSN frequently monitors surrounding environment for physiological changes and conveys the collected information to Base Station (BS) or Sink through a network of interconnected nodes. Resource utilization is major design constraint with WSN. Dividing nodes into groups to form cl...

jujube (zizyphus jujube mill), a valuable medicinal plant, is consumed either as fresh fruit or dried product in iran. drying jujube guarantees a longer shelf time while preserving its quality to be used in medical and pharmaceutical industries. in this research paper, the influence of several drying conditions on the effective moisture diffusivity, activation energy, energy consumption and req...

in iran the mainstreaming tool for integrating environmental concerns into energy sector is an energy-environment review (eer-iran). this paper comprises: (i) an analysis of the current situation with regards to energy production and consumption; (ii) an evaluation of the growth prospects with regard to energy production and consumption; (iii) the identification of environmental issues induced ...

with the increasing world population and limitations on arable land, increasing the yield per unit is one of alternatives human food supply. greenhouse cultivation as one ways of increase the performance can arrive this purpose. but the energy restriction of another human challenges, so that increase the performance without considering energy consumption almost appears to be meaningless. due to...
