Open-Circuit Regulator vs. Closed-Circuit Rebreather Diving

Benefits of closed-circuit diving. Though closed-circuit diving is much more complicated and expensive than open-circuit diving, it comes with several powerful advantages, one of which is a much longer bottom time. In a study, it was found that open-circuit divers consumed 17 times as much gas as closed-circuit divers. Since the gas in a CCR is ...

Open- Versus Closed-Circuit Filtration for Hydraulics Performance

In contrast to closed-circuit hydraulic systems, suction filtration is not a recommended filtration method with open-circuit pumps. This is due to the potential for high inlet vacuum to occur. Instead, a screen is recommended in the reservoir covering the pump inlet. A 125 µm (150 mesh) screen protects the pump from course particle ingression.

Energy efficiency of staged reverse osmosis (RO) and closed-circuit

Both staged and semi-batch RO (also known as closed-circuit RO, or CCRO) systems have been applied for the treatment of low-salinity (<1,000 ppm TDS) municipal and industrial wastewaters in practice (Arola et al. 2019). However, the energy requirements and efficiencies of different time-variant RO systems are still largely unclear.
