•The Main Nozzle is sized to provide a concentrate system resistance (concentrate pressure)
equal to the maximum design pressure at a constant design concentrate brine flow rate. The
auxiliary nozzle is sized to about 20-25% of the area of the Main Nozzle. The ANCV controls flow
to the AN in the turbine casing. The ANCV will provide a 20-30% pressure range at a constant
brine flow.

79. 79 NOT FOR DISTRIBUTION © Copyright 2010, ERI VERSION:0005-00 July 2010
System control and optimization
•To reduce brine pressure, open the auxiliary nozzle valve until the desired brine flow and pressure are
obtained.
•Opening the ANCV reduces the brine pressure and consequently reduces the boost pressure.
Opening the ANCV increases the total nozzle area, allowing more flow and/or a lower pressure. This is
typically done during those periods of RO plant operation that require less pressure than the maximum
designed membrane pressure.
•To increase brine pressure, close the auxiliary nozzle valve until the desired brine flow and pressure
are obtained. The TURBO will produce the most boost pressure when the ANCV is fully closed.
•The Aux Nozzle valve can be manual (as shown) or actuated.
•If automated, the best control signal is the brine flow.

dP = (Nte) x (Rr) x (Pbr – Pe)
Where Rr = ratio of brine flow to feed flow

Pbr = brine pressure at turbine inlet

Pe = Turbo exhaust pressure

Nte = Hydraulic Energy Transfer Efficiency from Curve

Turbo Pressure Boost – Example II.
Perth SWRO plant, Membrane feed flow 2‘453 m3/h, conversion 45 %, membrane feed pressure 57.9 bar,
brine pressure 57.2 bar, brine back pressure of 0.5 bar. What is the pressure boost???
AT-7200 = (0.82) x (0.55) x (57.2 – 0.5) = 25.6 bar boost

Flux Balancing
What is Flux?
•Defined as the permeate produced per membrane area
−Lmh: Liters per square meter per hour
−Gfd: Gallons per square foot per day

•Balancing flux between stages spreads the rate of fouling
deposition over the greatest membrane area
•Improves final system permeate quality when the flux is
increased in the last stages
•Reduces recovery in 1
st
stage and increases it on the 2
nd

stage
•Can reduce fouling potential in the 1
st
stage

PX Device Misconceptions: Fact versus Fiction
Fiction: PX Devices have higher operating expense than other isobaric
devices. PX比其他的等 压式能量回收装置操作 压力高。
FACT: The PX device has a peak efficiency of 98% and is being
operated in some of the lowest power consuming plants in the world
today. The PX has one moving part, no scheduled maintenance and has
the highest availability of any ERDs currently available.
PX装置的最大的效率是 98%，现在在全球正在以最低的能耗运行着。 PX只
有一个运 动部件，无需日常的 维护并且是所有能量回收装置中最适用的。
Fiction: PX Devices require excessive pressure before they start to
rotate. PX装置在启 动时需要更高的 压力。
FACT: PX devices need process flows (high-pressure and low-
pressure flow) and lubrication flow in order to rotate.
为了启动转子，PX装置需要工 艺流量（高压和低压流量）和润滑流量。

PX Device Misconceptions: Fact versus Fiction
Fiction: When operating multiple PX devices in an array, a stuck rotor will
cause overflow and damage to the operating PX devices.
当多个PX装置在一套系 统中运行时，一个停转的PX会引起超流和 对PX的损伤。
FACT: The PX device is passive in nature. The operable units will
continue to perform as designed. The inoperable unit will re-circulate
concentrate back to the membrane feed but the impact will be determined by
the number of devices in the array. Overflow to the operable units will NOT
occur. PX本身是被动转动的，运转的单元根据设计要求连续运行着。停 转的转子将浓水直接送入
给水且对系统的影响主要取决于 PX的数量。超流将不会 发生 。
Fiction: PX devices can’t be operated at the maximum rated flow.
PX装置不能在最大的 额定流量下操作。
FACT: All PX devices are designed to operate at full rated capacity and
the operators are free to do so. Installing additional capacity in an array does
have several benefits, including; optimizing performance, availability,
flexibility and longevity. 所有的PX产品都可以在最高的 额定流量下设计同时可以仸意的操
作，在一列中安装 额外的容量会有更好的 优势：优化性能、实用、操作弹性 和寿命长。

PX Device Misconceptions: Fact versus Fiction
Fiction: The high-pressure portion of the system can be filled via the LP
INLET side of the PX device.系统的高压部分可以通 过PX的低压给水部分填 补。





Fiction: PX units have a 5 year useful-life. PX只有五年的使用期。


FACT: The PX device is a passive device. The low-pressure and high-
pressure flow paths act as independent pipes flowing in opposite
directions with an integrated seal zone between the “pipes”.
PX是一个被 动装置。低压流量和高 压流量由于完整的密封区的隔离可以看成是两个相互独立
流道相反的两根管道。
FACT: PX units that have been commercially released and
commissioned in 1997 are still operating today. PX devices have yet
to reach their end-of-life or wear-out periods.
PX产品从1997年正式得投入市 场和运行至今， 还在不断的延伸其使用期和磨 损期。

PX Device Misconceptions: Fact versus Fiction
Fiction: ―Over-flush‖ is required by the PX device. PX需要超流。



FACT: The PX device does not require over-flush and a
majority of the PX installations operate with “balanced” flows. The
salinty increase at the membranes is typically between 2-3%
(depending on membrane recovery). Over-flush can be
implemented at the operators discretion.
PX装置不需要超流运行通常是要求在水量平衡的情况下安装及运行。膜 进口的含盐
量将会增加 2-3%（依据膜的回收率）。是否超流运行主要依靠操作者的要求。

Fiction: Small particles can cause a rotor to stop.微小颗粒可造成 转子的停转

FACT: Large debris such as broken pieces of PVC can cause a
rotor to stop but there are no known incidences of “small” particles
causing severe damage or stalling issues.
大的碎片，像 PVC碎片将会引起 转子的停转，但是小的 颗粒并没有听 说会引起危害等情

PX Device Misconceptions: Fact versus Fiction
FACT: PX devices require no maintenance. In fact, even after 5
years of operation, no spare parts or servicing is needed. This
provides more valuable, up-time (> 98%) compared with competing
technologies that need scheduled maintenance and a large stock
pile of spare parts.
PX无需定期维护。事实上，即使超 过5年的运行也无需 备品备件，这与需要定期 维护和
大量的备品备件储备的其他的能量回收来 说，这是非常有价 值的。

Turbo Device Misconceptions: Fact versus Fiction
Fiction: The turbos need to be isolated when cleaning/flushing the
system. 涡轮增压装置在清洗和冲洗的 时候需要隔离。
FACT:. The turbo does not require isolation during CIP, however it
is best practice to do so or flush thoroughly with fresh water
during system flush.
涡轮增压装置在清洗 时无需隔离，但是系 统清洗是最好采用新 鲜水进行冲洗。

Fiction: You must have a brine control valve upstream /downstream
of the turbo. 在涡轮增压的进出水口必须设置浓水控制阀门
FACT: NO, the turbine side of the turbo along with the aux valve
replaces the brine valve completely.
不需要。涡轮增压的透平段采用了 辅助管路阀门完全可以替代 浓水阀门。

Turbo Device Misconceptions: Fact versus Fiction
Fiction: You can flush the system through the Turbo
可以通过涡轮增压装置冲洗系 统
FACT: The turbine side of the turbo acts like an orifice plate and
requires a dP to pass water through. In fact, a bypass is used
for flushing.
涡轮增压装置的透平段 实际上像一个收 缩孔，要求有一定的 压差的水才能通 过，
所以需要一个旁路冲洗。
Fiction: Turbocharger must be coupled with high pressure pump.
涡轮增压装置必须和高压泵相连接
FACT: Not true, turbocharger can be mounted anywhere in the
plant for best fit into the plant design.
这是不正确的， 涡轮增压装置可以安装在系 统设计中认为最适合的地方。

Turbo Device Misconceptions: Fact versus Fiction
Fiction: Plant design with turbocharger requires brine disposal
pump. 设置涡轮增压装置的系统设计时需要设置浓水泵
FACT: Not true, turbocharger operates with brine exit back
pressure which can reach several bars thus eliminating need
for brine disposal pump.
这是不正确的， 涡轮增压装置是利用 浓盐水的出口 压力得到一定的 压力，因此无
需浓水泵。
