Phoenix UF

Seccua Phoenix. Safe water for the masses.


Meet the toughest regulatory standards with Seccua’s leading-edge Ultrafiltration: Certified pathogen-removal, integrated membrane testing, data-logging and web-based remote access. Plus full control over all required peripherals to filter water from any source, from waste to well water.

Ultimate Removal Performance

The nano-pores of the Seccua-Ultrafilters provide removal characteristics, that meet and exceed regulatory requirements for application of membrane filtration in drinking water treatment. The Phoenix has proven to fully remove virus, cyst and bacteria, tested also against US ASTM Standards. It also reliably reduces turbidity to under a level that downstream second barrier devices, like UV-systems, can function at efficiently.

Integrated Membrane Testing

The Phoenix has a fully automated, integrated, state-of-the-art membrane integrity test. It detects  membrane damages smaller than the size of pathogens. Together with its ability to monitor the signal of a turbidity meter in the filtrate line of the system (not included), it performs a continuous, indirect integrity test, triggering the integrated, direct membrane-test.

Treats difficult water

As the only one of its kind, the Phoenix continuously measures the actual degree of fouling of the membrane – based on a function of flow and differential pressure. The Phoenix automatically reacts to varying feed water conditions and adjusts the frequency of its cleaning cycles accordingly. In addition to a feed-pump it also controls dosing equipment in the feed to be able to treat high-color-containing sources using an inline-flocculation-process and achieve highest possible flowrates at maximum rates of removal of color and dissolved organics.

Cleaning-In-Place capability

Once the system detects a need for cleaning, it can apply different combinations of cleaning techniques, including pre- and post-flushing, internal backwash or backwash powered by an external pump, and it is even able to automatically perform chemically-enhanced Cleaning-

In-Place (CIP): Thereby the Phoenix co-ordinates a cleaning process including two different chemicals in sequence to allow e.g. high- followed by low-pH cleaning steps to get the system back to start-up conditions.

Remote monitoring- and alert-system

As soon as the system detects an operating-error, including a failed membrane-integrity test, but  also other differentiated messages, e.g. unsuccessful cleaning sequences, occurred water hammer, empty cleaning chemicals and other, it can send out an SMS message to up to ten cell-phones or report to an existing remote monitoring system. Once the unit is hooked up to an existing cellular network through its internal highspeed modem (optional), latest web-based, remote-control solutions allow the user to access the unit over the internet, change operating parameters and read operating history from the datalogger.

Highest Filtrate output

The Phoenix now offers higher filtrate output than ever: due to optimized filter-module construction and more membrane area, depending on the water quality, the system achieves a continuous  output of up to 1,280 liters per minute (0.5 MGD) and a short-term peak flow of up to 40 liters per second (632 gpm).

Performance Data

Removal performance

Virus (MS2 Phage)4: full removal (>5.7 log tested)

Bacteria (B. Subtilis, E-Coli)2,3: full removal (>9.7 log certified)

Parasites (Crypto)3: full removal (>4 log certified)

Water consumption during flushing typically less than 2%

1 Filtration performance depends on water quality and temperature. Please design carefully before deploying a Phoenix system and consult with Seccua Authorized System Partners for advice if required.

2 Bacteria removal of the Ultrafiltration membrane was measured against ASTM F838-05 standards.

3 Crypto and Bacteria removal was also tested by California Department of Health Services, the filter modules used (inge dizzer) are listed as „Alternative Filtration Technology“.

4 Virus removal of the Ultrafiltration membrane was measured against EPA standards.
