Seccua – leader in ultrafiltration technology for water purification
Seccua is the global technology leader in the field of standardized, packaged ultrafiltration systems for drinking water purification. Bacteria, viruses, Legionella and parasites; turbidity, colloids and coloration due to iron can be effectively removed from drinking water without the addition of chemicals.

More than10 years of experience in the field of ultrafiltration have culminated in systems with proprietary control systems incorporating automatic membrane integrity testing, data logging and remote monitoring and control. Our ISO 9001 certifed module manufacturing enables us to offer custom sized UF modules to OEM’s, and our system manufacturing is capable of producing over 1,500 systems annually.

Based in Steingaden, near Munich, Germany, Boston and Kansas City, both USA, Seccua has installed almost 1,000 ultrafiltration systems for residential, commercial and small-systems municipal applications. Products from Seccua are primarily aimed at local water supplies, for legionella removal and private water treatment. These compact systems can filter up to hundreds of gallons per minute and are easy and inexpensive to install and operate. They are fully automated and require low maintenance  They are ideal for places and areas not connected to central water supplies, but are also widely applied in buildings to remove legionella as well as in private homes that are concerned about city water quality. 

Seccua Ultrafiltration - the most efficient technology for water purification
Seccua Ultrafiltration is a technology that can turn contaminated water into safe drinking water. With significantly better performance and cost efficiency than any other purification method.

Seccua Ultrafiltration, which originates from medical technology, has been making its entry in drinking water treatment to an increasing degree. The purification process utilizes membranes, which have a pore size of 20 nanometers or less. Thereby they are smaller than all known pathogens present in the water. In this manner, ultrafiltration offers an almost 100%, chemical-free barrier against viruses, parasites and bacteria. Simultaneously, turbidity and all other suspended solids are removed from the water in a single step.

The removal of up to 99.9999 but more than 99.99 per cent of all pathogens has been proven in extensive tests, demonstrating that drinking water is completely free of bacteria after filtration. Seccua Ultrafiltration system have been tested to German DVGW standards, to NSF standards, to US EPA standards for pathogen removal and have been approved, amongst many others, by California Departement of Public Health for application in removing parasites and bacteria from Drinking Water under US Long Term Enhanced Surface Water Treatment Rule II (US ESWTR LT 2).

A further key argument for ultrafiltration, a low-energy treatment process, is its compatibility with other methods used for purifying drinking water. The use of activated carbon before ultrafiltration removes pesticides and drug residues, and with downstream nanofiltration, the water can be softened. Reverse osmosis will desalinate the water after ultrafiltration pre- treatment, much more efficient than without.

Seccua Product Portfolio
Seccua’s portfolio of products comprises the three product series UrSpring , Virex Pro and Phoenix which suit the needs and the volumes of water required.

The UrSpring systems, are applied to remove legionella from City Water lines at Point-of-Entry of cold water into private homes or apartment buildings with up to 30 apartments. They are also often applied to supply safe drinking water and to remove pathogens and turbidity from private wells, e.g. for lake-front cottages or private hunting lodges. UrSpring systems protect Embassies in newly industrializing countries. They are used to remove legionella and Pseudomonas from water lines jn Dentist or Doctors offices. Even in 32 high-speed trains built by Siemens, commuting between St. Petersburg and Moscow, Seccua UrSpring purify the drinking water served to the guests in the on-board restaurant and showers. The UrSpring systems require very low maintenance and run at lowest driving pressures (0.5 bar / 7 psi).

The Virex Pro system. This intelligent filtration system can purify up to a maximum of 3,900 litres of water an hour (18 GPM). It automatically detects how badly contaminated the filter is and automatically carries out cleaning processes at the appropriate intervals, if required with automated chemical enhancement. The control unit independently adjusts the interval between filter cleans, as well as the length of each filter clean, depending on the water quality, thereby ensuring simple operation and optimised running costs. The Virex Pro and Phoenix systems also feature an integrated membrane integrity test, complying to US EPA and German DVGW standards: The membrane filters used are regularly and independently checked for damage. In the event of a membrane fault, the system is stopped automatically and triggers an alarm locally and remotely. Thanks to this innovation, the removal of pathogenic organisms from the drinking water and a constant high quality of water can be assured. Seccua is the world market leader for this patented technology.

Within Seccua’s range of products, the most powerful system is Phoenix. It combines all the features of the Virex Pro unit with a space-saving, scalable approach to reach up to 43,000 litres of water an hour (190 GPM) of filtration performance. This system is ideal for disinfecting surface, spring and well water as well as for removing sediment or treating high flows of water in industrial processes. The Phoenix unit has also been installed many times into the Point-of-Entry of City Water lines in public buildings, apartment houses or hospitals to protect the buildings’ water-lines from legionella and other contaminants entering from the city mains. It not only then acts as a firewall, but it has also proven in many cases that existing legionella contamination and biofouling in water lines reduce significantly when installed at Point-of-Entry within only a couple of weeks after installation. Seccua Filtration is the only approach the removes the cause of legionella growth in water-lines instead of continuously fighting the symptoms!

From Legionella-removal in buildings to certified removal of pathogens in Public Water Supplies
Legionella can be found in nearly every well. Trough Public Waters Works they reach into the mains of our cities and from there into our buildings. Legionella require temperatures above 20°C (70 °F) to grow their population rapidly, which they find in some of our cities mains, but for sure do in the cold and warm water lines of our buildings. Latest studies have shown, that Legionella are able to resist hot water of 70 °C (158 °F) for more than 60 minutes. Inside the biofilm, which is present everywhere in our piping system, Legionella survive chemicals like chlorine, which is not able to reach into every shower in concentration high enough to efficiently disinfect and kill all Legionella. Furthermore, in most of our water-lines single-cell organisms are present, like Amoeba. Amoeba eat Legionella, but cannot digest them, so they keep growing inside Amoebas. When hot water or chlorine approaches an Amoeba, they often turn into most resistant cysts, which again turn back to its normal state when the attack by chemicals or temperature is over. Unfortunately, that is also the case in our lungs, where Amoebas are then killed by our immune system and set free the Legionellae inside in big numbers, leading to Pontiac-fever or Pneumonia. Seccua filtration, applied at Point-of-Entry of cold water lines into a building, prevents Legionella and all other pathogens from entering into the building. It has proven that after installation of a Seccua unit at Point-of-Entry, Legionella-counts at Point-of-use drops quickly, often to below detection limits.

Public Water Systems are often forced to use wells or springs for drinking water generation, which are under the influence of surface water. Typically those water systems are found in areas with only little top-soil, e.g. in Mountain ranges or deserts. Only a few minutes or hours after rainfall-events, the water from those wells can carry turbidity, together with pathogenic bacteria and parasites like Cryptosporidium. But studies have shown, that those pathogens can occur in affected wells also without turbidity appearing simultaneously, at almost any time. Cryptosporidium is highly infectious: In 1993 more than 400,000 people in the Milwaukee (USA) area got ill from Cryptosporidium, spread through the Public Water System, at least 104 people died as a consequence of that outbreak. But not only Crypto are a threat to our drinking water quality: Conventional technologies, like chlorination and UV disinfection, cannot deal with turbidity spikes in the feed water. They are best used on crystal clear water with only pathogens left in it – but where can such water be found? In opposite to that, Seccua filtration technology has proven to remove all bacteria, parasites and virus together with turbidity from water in one single treatment step. Seccua filtration technology has been tested to US EPA standards for full pathogen removal and has been approved by many States in the US, amongst those the State of California, for use compliant with US LT Enhanced Surface Water Treatment Rule 2. Seccua filtration is successfully applied in hundreds of installations worldwide.

Similar to Public Water systems, private wells, supplying farms, cottages and lodges, suffer from the same difficulties. In many cases they get their water from lakes directly or wells under the influence of surface water. Other than Public Water supplies, equipment that goes into such application has to be even more rugged and easy to use without compromising on its performance. Seccua filtration is an ideal solution for such cases. In test, undertaken by the Minnesota Department of Public Health, Seccua filtration, in conjunction with effective pre-treatment technology, has shown to effectively reduce color from the water and therewith reduce creation of carcinogen chlorination-by-products downstream of the Seccua treatment.

Revolutionary Seccua Technology allows treatment of Produced Water in Hydraulic Fracturing
Hydraulic fracturing – fracking – requires a lot of water. Water is used to crack the rocks far below the surface and allow the entrapped gas bubbles to reach the bore-hole and then surface. To keep the fractures, generated by shocks of water-pressure open, little silica sand particles are sent down together with the water into the bore-hole. Also, gelatin is added to the water to keep the sand-particles in float in the water. Typically, two-thirds of the water pressed into a bore-hole comes back out over the course of a couple of months. This water contains sand, natural oils, bacteria from the ground, high concentrations of sodium chloride and many other contaminants. To be able to remove dissolved solids like sodium chloride from such water using technologies like Reverse Osmosis, all particles have to be removed first. Water industry has been working to solve this task for a long time. Seccua has developed a revolutionary filtration technology, based on most advanced sinter-technology, to remove suspended solids, oil and grease and bacteria in one treatment step.
