Company
We are a full-service manufacturer of equipment for industrial wastewater treatment.
All of our wastewater treatment equipment is designed and manufactured down to the last detail at our facilities, which allows us to maintain complete control over the final quality of our products. As a result, we can offer the highest guarantees of efficiency, reliability, and durability for every unit we deliver.
We have three manufacturing facilities with a combined production area of over 12,000square meters, equipped with state-of-the-art handling, machining, and assembly equipment.
Our production facilities are divided into separate complexes, each dedicated to the production of a specific family of technologies. In addition, we have our own laboratory, pilot plants, and a customer training center.
Our workers have been accredited by the International Business Control Agency in order to ensure the highest manufacturing quality of our products.
Our experience
SIGMADAF was founded in 1994, and since then we have built thousands of wastewater treatment plants for a wide range of industrial sectors across five continents.

Years of experience
We have carried out installations in all types of locations and terrains, from simple assembly projects at a client's facilities to complex infrastructures in difficult to access terrains.
Our wastewater treatment plants ensure maximum efficiency in removing contaminants and clarifying water for reuse.
Thanks to our complete control over our design and production processes, we can guarantee the maximum durability and efficiency of every piece of equipment we deliver, whether for industrial or municipal applications.

Our manufacturing process
Our water treatment equipment is manufactured entirely at our facilities. Once an order is received, the following manufacturing process begins:
Analysis
Design
Manufacturing
FAT Tests
Startup
We use the latest 3D design tools for the detailed design of all the equipment manufactured in our workshop.
One of our goals is to equip our frames with sections that enhance structural rigidity without adding unnecessary elements to the overall design. We have achieved this through:
- Laser cutting of all equipment parts
- Joining of parts through a process and order defined by 3D models
- Modularity
- Materials and finishes
Each component of our equipment is identified by a unique code to track the status of each part and simplify subsequent assembly.
As for the metal parts of our machine (chassis, frame, reinforcements, etc.), this code will be laser-engraved so that, during assembly, errors are completely eliminated from the process.
Finally, before shipping the equipment to the customer, we conduct the necessary quality tests to ensure that the machine will be delivered in perfect condition and ready for operation.
Materials of construction
| Material | Applications of decentralized STP |
|---|---|
| COATED CARBON STEEL | Carbon steel is used for the production of a wide variety of products due to its strength, hardness and ease of welding. Our carbon steel is coated with a zinc layer to protect it from humidity, thus preventing rust and corrosion. |
| POLYPROPYLENE - (PP) | Polypropylene (PP) is corrosion resistant to both acids and alkalis. It is also highly resistant to high temperatures. Thanks to these characteristics, it is a perfect material for desalination projects in seawater and oceans. |
| STAINLESS STEEL AISI304 | Type 304, with its chromium-nickel content and low carbon content, is the most versatile and widely used of the austenitic stainless steels. Its alloys are all 18% chromium, 8% austenitic nickel alloy modifications. Type 304 proves to be resistant to oxidation, corrosion and durability. |
| AISI316 | The difference between 304 and 316 has a simple answer: 304 contains 18% chromium and 8% nickel, while 316 contains 16% chromium, 10% nickel and 2% molybdenum. Molybdenum is added to help resist corrosion from chlorides (such as seawater and de-icing salts). |
| SUPER DUPLEX | Super Duplex stainless is a mixed microstructure of austenite and ferrite (50/50) that has improved strength over ferritic and austenitic steel grades. Duplex alloys have higher strength and better resistance to stress corrosion cracking than most austenitic alloys and higher toughness than ferritic alloys, especially at low temperatures. |
United Nations Global Compact
We are pleased to inform that SIGMADAF Clarifiers is recognized as a sustainable supplier by the United Nations Global Compact. United Nations Global Compact. This recognition reflects our commitment to the Global Compact's universal Ten Principles, which cover human rights, labor standards, environment and anti-corruption.
The United Nations Global Compact is a call to companies and organizations to align their strategies and operations with these universal principles, in addition to promoting the Sustainable Development Goals (SDGs) in the private sector. Its mission is to generate an international movement of sustainable businesses to create the world we want, and it has the unique ability to unite companies with other actors such as governments, civil society and the United Nations itself in promoting sustainable development.
