Sentence examples for backwash cycle from inspiring English sources

However, the glass media had superior flow characteristics and was able to treat an additional 8 10% of the influent following the backwash cycle.

Evidence from transmembrane pressure (TMP) monitoring suggests that the sudden decrease in backwash efficiency occurs when the pressure on the permeate side of the membrane at the end of a backwash cycle does not reach the atmospheric pressure maintained on the feed side.

All selected pools had a sand filter (most public pools in the metropolitan Atlanta area use sand filters) and had been used by swimmers before the backwash cycle and sample collection began.

Let the conditioner run through the complete backwash cycle when installing a water softener.

The fouling rate was measured by the decline in specific flux over many backwash cycles.

Modeling and experimental results in this study show that the effectiveness of fixed backwash cycles can decrease over time and reach a point at which the backwash effectiveness suddenly decreases.

Meanwhile, The samples still retained the underwater superoleophobic property after 4 separation-water backwash cycles (> 140 continuous separation repetitions) with the separation efficiency always remaining above 95%, which indicated the excellent recoverability and recyclability.

The results showed that the removal efficiencies of formation potentials (FP) of DCAN increased from 28.9% to 64.4% with the optimized ozone dose, expansion rate of BAC and backwashing cycle, being scheduled to 1.52 mg/L, 27% and 9.5 d, respectively.

Variations in operating modes and conditions were tested, from dead-end operation to semi sequencing batch operation using air scouring and backwashing cycles for membrane cleaning and fouling control.

More interestingly, the optimal control solution and proposed implementation strategy are consistent with empirical demonstrations but provide mathematical evidence that the flux may be increased dramatically by precise timing of the forward and backwashing cycles.

During this mode, an elevated high instantaneous flux (60 L m−2 h−1) is initially applied for a short time (120 s), followed by a longer filtration (290 s) at lower flux (10.3 L m−2 h−1) and a backwash in each filtration cycle.
