Tilek AB

Tilek Aktiebolag is a Swedish company which has developed a new process to remove harmful components from ground water in order to produce drinking water quality.

The work is concentrated on elements such as arsenic, lead and uranium. They are present in ground water at too high concentrations in many countries in the world.

The process for their removal is based on the use of oxides of iron and manganese.  A combined solid product of these compounds has been demonstrated to have excellent capacity to eliminate the elements mentioned.

The process developed is named Tilaquas.  It takes place in two stages: In a reactor tank followed by a particle separation stage.

Six commercial installations have been built. An additional contract for a Tilaquas installation in Sweden with capacity to remove lead, uranium, nitrite, iron and manganese with a capacity for 15 households has recently been signed.

Standard equipment is used.  A normal pressure tank is used as reactor. A suspension of the solid particles is fed by a small membrane pump into the water at times when water is flowing into the tank.  Due to turbulent conditions inside the tank the contact between solid particles and the incoming water is efficient. A normal sand filter with automatic flushing is used for separation of the solid particles with its impurities.

Tilek is looking for an established company in the field with good knowledge of the market not only in Sweden but also in other countries for cooperation in the further commercialization of the process.

From biogas to electricity

Againity has developed an innovative system producing electricity from heat in biogas boilers, gas engines, gas turbines and any other heat source from 90 degrees Celsius. The system is based on the ORC (Organic Rankine Cycle) technology and an in-house developed steam turbine. The system can utilize heat down to 90 degrees Celsius and still have a short payback time for systems down to 20 kW. Today four ORC systems are up and running on the Swedish market where biogas from waste water treatment plants have become a major customer segment. The ORC system is delivered pre-fabricated and installed by a simple pipe connection of the heat source and a cable to the power grid. It is fully automated and a TCP/IP connection allows convenient monitoring and remote control. The turbine system consists of high-quality components, designed to last long periods without maintenance. At Againity we happily help with suggestions of technical set-up and financial calculations for potential projects.

Ecofiltration Nordic AB

Ecofiltration is a leading environmental technology company which is developing, manufacturing and selling scalable Polonite phosphorus filters that remove and recover phosphorus from sewage water. The reactive filter media also has other good features that can be used to treat sludge, odour, disinfection and micro-pollutants. The filter media can be used as small filter solutions for private sewages, large filter solutions for wastewater treatment plants (WWTP), both municipal and industrial, and specialized solutions for agriculture and animal husbandry.

Phosphorus is a finite resource that causes eutrophication and needs to be returned to productive soil in a sustainable way. After treating wastewater, saturated Polonite is rich in phosphorus and can be used as a fertilizer that releases phosphorus in the same pace as the plant’s uptake.

Ecofiltration is headquartered in Stockholm, Sweden with 10 employees and have sold more than 6000 filters for private sewages and 200 small scale WWTP in Sweden. Ecofiltration is also operating in countries surrounding the Baltic Sea such as Poland, Russia, Germany and Baltic countries and also in selected countries like the UK. Pilot installations on large phosphorus filters are set up in Sweden, Russia and the UK. The technology is based on over 20 years of research at The Royal Institute of Technology in Stockholm, Sweden.

Join us in our mission for a better future. Filtering for life.
