Our product offering
SF200
Compact filter particularly suitable for pilot plants and for small scale applications.
It travels conveniently on a pallet if you wish to keep it mobile. When permanently installed at your site, it requires a very small floor space.
The SF200 has a filtration area of 0.2 m² and a capacity up to 5 m³/h.
It comes with its own data-logging system and the fully automatic filtration and cleaning procedures.
SF1000
Highly effective filter for industrial environments.
Modular and scalable for high capacity requirements.
No chemicals, automatically self-cleaning - it keeps your operational costs and operator intervention minimized.
The SF1000 has a filtration area of 1 m² and a capacity up to 35 m³/h.
Built-in IoT that enables remote monitoring and troubleshooting.
CONTAINER
Sofi container for remote locations and, when protection against the elements is important or when you need your equipment only periodically.
The container is either 20’ or 40’ and contains three or six SF1000 filters and all auxiliary equipment.
The capacity of the solution is up to 200 m³/h, depending on the feed characteristics and the number of SF1000 units.

Patented Innovative Technology
No disposable
filters
Our filter elements are made of metal and thus durable and have a long lifetime.
Ultrasonic Self-cleaning
Assisted by ultrasound and back pulsing, we can keep the filter clean and guarantee high performance.
Novel Cross Flow Design
Patented cross flow design allows for high flux while keeping particles from fouling the filter element.

Frequently Asked Questions
-
Yes, our solution is modular. To increase in capacity, we just multiply in units. Our filters are very effective in floor space, don’t require large vacuum pumps, don’t use chemicals, don’t have regularly disposable parts, and are automatically self-cleaning to promote minimum operator intervention.
-
The quantity of reject depends on the solids loading (total suspended solids, TSS) of the feed and on the system configuration (cross-flow, dead-end). To understand the range, for high TSS the water recovery is around 70% (i.e. 30 % of the feed end up as reject) and for low TSS water recovery is up to 99 % (i.e. down to 1 % of the feed ends up as reject).
-
Reject handling is very dependent on the application and the actual site, as different treatment options are available at different site. Some sites have filter presses, clarifiers, or other up-stream processing where the reject can be sent to. Some sites collect the reject into a dewatering bag and transport it elsewhere for processing, since the quantity of reject from our filters is typically very low. Some sites, in turn, burn the reject for energy or can send it back to the process for the solids to be used again. We work together with our customers in identifying the most suitable option.
-
No. We separate solid particles that are detrimental for any treatment where you aim to separate dissolved material. We collaborate with other companies in understanding the requirements for solute separation and offer our filters as an effective pre-treatment option.
-
Our filters are highly durable even in aggressive environments. Standard maximum feed temperature is 85 °C. With special components maximum temperature can be increased up to 115°C.
-
Our filters use low feed pressures (0.5–1.5 bars). Typically, energy consumption is approximately 0.5 kWh/m3 purified water, including the pump, the ultrasounds and compressed air consumption.
-
Typically, 25 L/min at 6-8 bar pressure.
-
As default, the filters come equipped with pressure and flow sensors. For further monitoring, e.g. pH, conductivity, and temperature sensors can be installed.
-
Yes. We can supply you with a digital solution for data collection and remote monitoring that enables us to access the data and remotely monitor and do diagnostics for our filters to aid you in troubleshooting.
-
We can provide you with regular chemical cleaning and maintenance of your filters once in operation. We help you when you need spare parts or want new filter elements of the same or different pore size.
