Sophisticated operating features.
Yet simple to operate.
A high-performing and lasting UF system requires fusion of many sophisticated operating cycles
and features. To support these, the system also needs many integral equipment and high-quality
parts and components, well integrated to achieve optimal results of what UF technologies can
offer. What more about making the eventual UF system simple and user-friendly to operate and
maintain. It takes a great deal of the deep understanding of UF technologies, established process
experiences and innovative expertise to make it. We make it. For you and the industries.
Operating features and cycles.
Fully automated. Minimum human attendance.
The diagram depicts generally the process flow (cross-flow configuration) of our standard UF systems, especially those fitted with our inside-out and outside-in UF modules. For the systems fitted with our A-series UF modules, the process varies slightly from those shown in the diagram. Typically, our feed pumps first channel the feed water through screen filters to remove all large-sized solid particles to protect the UF membrane downstream.
Subject to the feed water qualities and selection of our UF membranes and modules, the filtration cycles usually take place for 20 to 60 minutes, before backflush cycles begin. During the filtration cycles, there is continuous cross-flow stream out of the modules sending contaminant concentrate to feed water tank or to drains. Depending on the UF modules selected, the backflush cycles may entail top and bottom backflush sequence, each taking less than 60 seconds to perform, and the filtration cycles resume thereafter. Except for our inside-out UF modules, backflush cycles are aided by air-scouring process to remove particulate deposit on the outer membrane surfaces more effectively.

backflush (CEBF) process.
24/7 auto-mode for the right dosage.
CEBF is a necessary process to clean and protect UF
membrane well in the long run, unless the feed
water is of rather high qualities. Typically, our UF
systems are incorporated with automatic CEBF
systems for the dosing of chlorine (NaOCl), alkali
(NAOH @ pH 12) and acid (H2SO4 @ pH 2) for
disinfection, removals of organic and inorganic
fouling respectively. Dosing of other chemicals may
be recommended subject to feed water’s
contaminant content. The frequency of CEBF is
subject to feed water qualities.
Clean-in-place (CIP) system.
Pre-built system to make process easy.
We usually supply separate pre-built CIP systems along
with our UF systems. CIP operation is performed on a
demand basis when the overall flux of the UF modules
has declined to a consistently low level. The frequency
of CIP is dependent on the feed water qualities and can
range from 1 to 3 months, when some stubborn
foulant may have built up on the membrane surface.
Filtrate quality analyses.
Made simple with individual sampling valves.
We make the filtrate quality testing process simple too. The filtrate outlet of each of our UF modules is fitted with a filtrate sampling (ball) valve as our standard feature. This allows the end-users to collect filtrate samples easily, and at any time and frequency, from each UF module for quality analyses at their laboratories. This helps detect any individual defective UF module more quickly, than to have to carry out membrane’s integrity test on each module at a time to identify any defect.
efficiency and integrity.
Clear pipes to make quick visual
The filtrate outlet at the top (after filtrate sampling valve) of each of our UF modules is fitted with a short section of acrylic clear pipe. It allows quick visual observation of flow efficiency of water through each module, helping to detect any mechanical or instrumental faults within the module bank of continuous large air bubbles flowing through a clear pipe section indicates membrane breakage of the module concerned. It helps identify the individual defective module easily.
module’s integrity tests.
Bubble tests. Pressure decay tests.
The clear-pipe feature is also essential when bubble-
test procedures are carried to determine precisely
the integrity of the membrane in each module. It
provide visual inspection of any occurrence of large
air bubbles flowing through during bubble-test
process of each module. When required to determine
the overall integrity of each module, pressure-decay
test procedures are recommended. The details and
procedures of these tests can be found in our
operation manuals provided along with the
deliveries of our UF systems.
It all begins with the selection of
right UF membrane and modules.
Let the right UF membrane and
modules work the most for you.
Not the other way round.
An ideal UF system should be one fitted with the most
ideal membrane and module configuration to handle
your feed water and produce the desired water quality.
This enables you to exploit the best abilities of your UF
system for your application, saving substantial costs and
footprint from having to invest in complicated pre- and
even post-treatment facilities to aid the UF system. This
is where an optimal UF system shall begin.
Optimal-performing UF systems.
With our wide membrane variety and
innovative Ø10” module configurations.
We feel so powerfully versatile when we could combine
a good range of our proprietary membrane materials
with a few innovative Ø10” module configurations to
produce a range of the best performing UF modules.
From modified Polyethersulfone (PES), Polyvinylchloride
(PVC) and Polyvinylidene (PVDF) materials, to different
hollow membrane fibre’s diameters and pore sizes, to
inside-out, outside-in and aeration-series module
configurations, the choice of versatile combinations
enables us to provide you with the most optimal
performing UF systems to meet your needs.
High-quality equipment, parts and components
integral to optimal UF performance.
Typically, our standard and packaged systems, whether one-and-two-module or multiple-module
systems, come with multi-stage feed and backflush pumps, VFD devices, screen filters as membrane
protector, built-in chemical enhanced backflush (CEBF) systems with chemical dosing pumps and tanks,
control panel and instrument content, and a whole host of other parts and components. Our UF systems
also come with membrane’s clean-in-place (CIP) systems, either built on the same skids, or on separate
skids. Air compressors are needed for the control of pneumatic valves, as well as for backflush air-scouring
functions (and for constant fine-air-bubble aeration during filtration mode of our A-series UF modules).
Where necessary, we may supply pre-built pre-treatment systems, or provide the end-users with our
expertise to construct such at their ends. Raw water and product water tanks, air compressors may be
provided by the end-users.
Where the intelligence gathers.
Where the intelligence begins.
To, at and from the control panel. It is like our brains.
It gathers signals and data. It stores and analyses
information. It controls, coordinates and manages
functions. A high-performing UF system may begin
with the selection of right UF membrane and
module. But it does not end without a well
instrumented and intelligently programmed control
panel. All the sophisticated operating features. All the
advanced hardware. All the versatile instrument. They
need the most intelligent PLC programs to make
them work best in tandem. If you look at and look
into our systems’ control panels, that is simply what
we do – it has to be intelligent to be simple – for you.
Powerful, reliable, flexible and versatile.
Programmable Logic Controller (PLC).
In automating our UF systems’ sophisticated
operating features for optimal performances, we
choose to use some best PLC platforms for
programming and configurations. We are
versatile in applying the PLC platforms offered by
some of the most globally established brand
names. We do all the process control and
function programming in-house, a water
company that is truly specialised in optimising
both the features of the hardware of its water
systems, and the programming software that
controls these features.
Managing your UF system
with a touch of your finger.
We make your real-time monitoring, tracking, trending
and optimising the performances of our UF systems so
much simpler. With a touch of your finger. Literally. We
program all these essential functions into a Human
Machine Interface (HMI) touch-screen device fitted in
our control panel. Powerful and innovative, these panels
include numerous advantageous features like
connectivity and networking platforms, wide range of
graphics for video or data displays, internet connectivity
supported by most serial/ethernet protocols, versatile
drivers working compatibly with just about any external
device from PLCs to barcode readers.
SCADA connectivity (optional).
Complex analytics and decentralised access
of water treatment plants’ data made simple.
For large water treatment plants with multiple UF skids, multiple and separate peripheral stations such as intake pumping facilities, product water’s distribution points, chlorination stations etc (or to centralise monitoring and control of multiple UF plants at different locations), we can scale the HMI connectivity platform to a SCADA (Supervisory Control And Data Acquisition) architecture. SCADA architecture and devices allow complex analytics of the operating data of multiple equipment locations to be carried out at a centralised server, while monitored, viewed (or controlled) by multiple personnel at decentralised locations, with wireless or internet networks.
Remote monitoring made simple.
Wherever your plant is. Wherever you may be.
Whether our UF systems are fitted with HMI devices or connected by SCADA networks, we have
developed in-house remote monitoring and control protocols and systems to make your life even
easier. Through mobile telecommunication or internet systems or both, our monitoring systems focus
on the most essential operating parameters and data that may require your attention and actions.
Alternatively, our teams, agents and distributors could provide you with the monitoring and troubleshooting
services. If so, we could help you optimise the performance of the UF system/plant further,
saving you more operating costs in the long term.
