SEAM engineering is an engineering company located inside ComoNext, an Innovation Hub in Lomazzo (Como, Italy).
Founded in 2005, SEAM engineering can rely on specific skills in the design of wastewater treatment plants, liquid waste and air treatment, as well as on a deep knowledge of related environmental issues.
The targeted experience in the water treatment sector has led to a solid know-how in consulting and prevention, besides the capacity of providing solutions according to the requirements of the current legislation and the environmental management systems.



Competences acquired by SEAM engineering are of interest for many civil and industrial applications, specifically in the following sectors:

Refinery oily water treatment, chemical-physical treatment, biological treatment with specific technologies for each application (SBR-MBR-MBBR-CAS). Gap analysis for the evaluation of existing systems. Wastewater treatment up to Zero Liquid Discharge systems.

Wastewater treatment, analysis of process wastewater, intervention on the production process (potential modifications), application studies for plants in Italy and abroad, ammonia treatment (ANNAMOX technology). Colour treatment / chemical oxidation.

Support in the design basis definition, gap analysis for the evaluation of existing systems (identification of potential critical issues and technical solutions). Design of specific systems: chemical-physical treatment, chemical oxidation, biological treatment (SBR-MBR-MBBR-CAS), advanced tertiary treatment (AOP).

Support in the design basis definition, gap analysis for the evaluation of existing systems. Tertiary treatments for the discharge in environmentally sensitive areas; odour control. Systems for supernatant treatment via anaerobic digestion (nitrification-denitrification) realized for ASIL Merone (Como, Italy); systems for energy recovery and cogeneration; improvement of anaerobic digestion with organic waste.

Support in the design basis definition, gap analysis for the evaluation of existing systems. Design of chemical-physical pre-treatment of specific waste; optimization of existing plants and evaluation of tertiary treatments. Due diligence inclusive of technical-economic analysis for purchase and insurance; as well as performance review pursuant to ISO 9000/2015 and 231/2001 procedures.

Sampling plans and support in the design basis definition. Design of plants for the treatment of dairy wastewater, gap analysis for the evaluation of existing systems and optimization studies. Definition of design datasheets and writing of specifications for the purchase.


SEAM engineering supports the projects of Anffas Onlus Seregno Brianza, for the protection and respect of the rights of people with disabilities, for their social inclusion and a concrete improvement in the quality of their life.

SEAM engineering is always at the forefront in moments of in-depth analysis with research bodies. We are sponsor at the fifth IWA EcoSTP2021 conference “Ecotechnologies for Wastewater Treatment”

For the sixth consecutive year, SEAM engineering supports Como students and their young talents by establishing the NuovoodiNuovo award on the occasion of the Innovation Day organized by the Como-Lecco Chamber of Commerce. The project that will present the best product or process innovation in the environmental sector will be recognized as the winner!


SEAM is independent from any manufacturing company. This guarantees that our work is aimed at achieving the best solution for the customer, without any conditioning related to the commercial employment of specific products.

SEAM has a network of multiple complementary competences and a structure of technicians with a working capacity of 20.000 h/year.

SEAM employs the latest technology; in terms of innovation we can list collaborations with
