The only UF that purifies your water from all viruses with its 0.01 micron pore size


units and modules

Rielli ultrafiltration plants  pass the water through a special membrane with pore size of 0.01 microns and all suspended particles are trapped on one side of the membrane. By this technology  water is separated even from the smallest particles including viruses. Rielli UF plants are not only used for the recovery of waste water but are also used for the treatment of potable water, in water bottling facilities and, especially for the RO pretreatment.

Competitive prices increase your competitive power.

We purchase each component that we use in the production of Rielli Reverse Osmosis plants directly from the manufacturers.  As a matter of our production capacity we purchase large volumes of  components, which decreases our cost and, thus increases your competitive power. We manufacture our products cost-efficiently and productively without compromising our quality and occupational safety. Our business model enables you to save money when purchasing our products and forms a part of our policy to increase the competitiveness of our partners.

Manufactured at higher quality standards.

As a result of many quality control and compatibility tests during the entire process of production from the raw materials to the finished products,  in particular, at the integration stage. Rielli UF equipment are manufactured  with perfection to match our high quality standards.

Short delivery periods.

We manufacture most of our Rielli Plants based on special projects designed according to your orders. We keep most of the components at stock in a way that they are ready for the production or get them quickly since we directly work with the manufacturers and deliver them to you within the shortest period of lead time. We are capable of meeting your extremely short deadlines that you may request thanks to our flexible and large production capacity, advanced logistics facilities and manufacturing technologies.

Manufactured based on an experience of 28 years.

Corporate experience behind each Rielli equipment manufactured is more than a quarter-century, but the experience behind the brand Rielli is based on the tradition of a family which has been in the production business since 1955.

Our expert staff of engineers

and our direct relationship with the component manufacturers allow us to give you the most optimal solution. We know how to use the tradition and the latest developments of technology in harmony when manufacturing Rielli softeners and filters. Our staff of engineers are our fellows who have been with us during the most of our journey to success. Thanks to these great technicians and engineers combining their experience in our company, with their knowledge and skills and, our long-term partner Litree (A world leading manufacturer of membranes) for more than ten years, we are capable of designing and manufacturing the most efficient ultrafiltration plants in terms of investment and operating costs

Unique user experience

Each Rielli UF plant comes with a user manual specially prepared for the respective project. Our technical team provides user training after the installation and issues certifications upon the successful completion of training. Using follow-up tables, online monitoring and after sales services we guarantee the lifetime proper operation of our plants as per your needs and expectations. Our assembly team and after sales technicians are at your service for your Rielli equipment wherever it is installed throughout the world: whether in a remote village of Ethiopia or in a holiday hotel of the Philippines.

An investment that pays off itself from the day one thanks to financing opportunities specially designed for you.

Financial facts and figures are presented on the first page of every Rielli UF plant offer. So potential clients can see on the first page the financial advanteags of owning a Rielli plant. The initial investment cost, operating cost, return of investment perios and many other related data is presented in details. Your investment can positively contribute to your cash flow thanks to the options of purchase or rental of the equipment or purchase of the water produced making use of the financial possibilities that we can bring you.

We use the one of the best and energy efficient UF membranes on the market.

We get the UF membranes that we use in the production directly from Litree, one of the world’s best membrane manufacturers, which allows us to be the first one to offer the most advanced technologies for the most affordable prices.

Most of our technicians and engineers have been working for our company for many years.

We are not only preferred by our customers but also by our employees, which allows us to have a well-established corporate culture with a technical experience of decades focusing on quality and productivity. Would you too like to be a part of this experience?


Litree ultrafiltration membranes we use in the Rielli ultrafiltration plants:

Make your water free even from viruses. Pore sensitivity of the membranes used in the Rielli UF plants would not allow even viruses pass through. In this manner, it provides treated water free from microorganisms without the need for an additional disinfection chemical most of the time.
It has one of the smallest pore diameters at the sector with a filtering sensitivity of 0.01 microns at the limit of nanofiltration. Such a sensitive filtration keeps all Suspended Solids and microorganisms including viruses as may be present in the water. This structure delivers the most sensitive filtration within the scope of ultrafiltration.

Despite this small pore diameter, it runs at low pressures and consume less power thanks to its hydrophilic materials. Under the appropriate conditions, it may run without the operation of its suction pump.

Operating costs are reduced since the chemical washing period of the membranes is longer by 2-4 times compared to equivalents.
It may be used without the need for pre-filtration or coagulant even with very high levels of Suspended Solids and turbidity.
