  Air Recirculation - an overview | ScienceDirect Topics

  Central recirculation means that some part of the air exhausted from a room is passed through an air cleaner and then returned to the room, either directly or by mixing into the supply air. When the main contaminant source is in the supply air, this system should result in cleaner air than when using only outside air.

  Water consumption assessment in mineral processing …

  2023101 · Abstract Water is essential in mineral processing. Because water is a limited resource and many mining operations are located in water-scarce areas, proper water management is crucial. An alternative to facing water scarcity in mining is its reuse in the process. Water recirculation is limited because there are water losses associated with …

  Effects of flue gas recirculation on energy, exergy, …

  The effect of the location of flue-gas recirculation (FGR) on the 4E values was investigated for wet FGR (wFGR) at 170°C, dry FGR (dFGR) at 68°C, and 80% wet and 20% dry FGR (wdFGR). The net electricity efficiencies of the wFGR and dFGR power plants were 37% and 36%, respectively.

  Model and control scheme for recirculation mode direct …

  2017915 · Hirsch and Eck [13], [14] proposed a nonlinear dynamic model for DSG parabolic troughs. This model was developed for the recirculation mode and had been selected for the first pre-commercial plant Integration of Direct steam generation Technology for Electricity Production (INDITEP) [15].

  Effects of water recirculation on microalgae assemblage and ...

  202221 · Abstract An algae photobioreactor (APB) was used to determine the effect of water recirculation on the growth of algal assemblage. CO 2 in the flue gas from a power plant was the carbon source. Boiler water was used as the source water.

  Design of Trickling Filters | Sewage Treatment | Sanitary Engineering

  6  · Design a high rate trickling filter plant to treat settled domestic sewage having BOD of200 mg/l for an average flow of 22.50 mLd to satisfy an effluent BOD s of 10 mg/l. Adopt peak factor as 2.25. Solution: As the efficient BOD 5 required is less than 30 mg/l, a two-stage filtration plant shall be provided.
