The BIOBOX® proposal: BIOBOX® Nitrates, Mar Menor Murcia case study

The BIOBOX® application for climate action has recently been approved.

Success story BIOBOX® Nitrates, Mar Menor Murcia

Objectives and scope

The Mar Menor lagoon, located in Murcia (Spain) is the largest permanent saltwater lagoon in Europe. It is a unique natural enclave of great ecological and scenic value. However, it is currently facing problems of nutrient pollution, mainly nitrates. They have caused a serious process of eutrophication of the lagoon.

As part of the specific action plan to solve this problem, it was decided to use a biofiltration process based on biological heterotrophic nitrification. It was then when BIOBOX® proposed to carry out a pilot project to demonstrate the effectiveness of the BIOBOX® Nitrates technology.

BIOBOX® is the new company that designs and manufactures Plug&Play compact water treatment plants. 100% automated plants for the treatment of drinking water, urban or industrial wastewater and reuse. The brand is the result of an intense effort in R&D&I. It is based on the experience and lessons learned by two leading companies in the sector: Ingeobras and Filtralite (Saint-Gobain).

BIOBOX® Nitrates integrates a proprietary patented technology called Puremust-sn®. Unlike other traditional separation technologies, such as reverse osmosis or anionic resins, BIOBOX® Nitrates is able to transform nitrates into harmless nitrogen gas through the natural action of bacteria.

It is a 100% sustainable technology whose nitrate removal yields are over 95%. Moreover, it is a viable solution available to all types of companies, with operating costs of less than €0.15/m3 when treating drinking water and less than €0.10/m3 when treating wastewater.

This pilot project, which lasted four months, obtained outstanding results. In fact, BIOBOX® has been chosen by the Government of Murcia as a viable solution – technically and economically – to eliminate nitrates from the watercourses that flow into the Mar Menor.


BIOBOX® Nitrates (Puremust-SN®) already has numerous references from national and international projects. It has also been certified by the the Swiss multinational company SGS and is accepted by Spanish health authorities. Each BIOBOX® plant is tailor-made and adapted to the needs and space requirements of each client.

Associated Indicators

Results of the Mar Menor Murcia pilotage:

  • Nitrate removal performance over 97%.
  • Removal remains constant and stable
  • COD at outlet well below discharge to public watercourse and below COD at inlet
  • Treatment cost below 0.1 €/m3


This initiative once again demonstrates the effectiveness of the BIOBOX® Nitrates technology. It is a project of interest to all technicians or managers (in both public and private industry) who identify a need in the treatment of their water and require a solution that is adapted to their needs and is environmentally friendly.

Moreover, finding a solution to a problem that has been threatening the biodiversity of the lagoon for decades is a matter of general interest.

Next steps:

The selection of the most outstanding initiatives will be made by the expert committee from 16 October. The results will be published on the initiative’s website from 1 November 2022 and officially presented at COP27 in Sharm el-Seikh.
