A Spanish SME specialized in the sustainability field has designed and developed a new system for natural swimming water depuration. The product is totally adaptable to any pool dimension, and the biological filter is based on living aquatic plants, so it does not need any them http://ical product for water purifying. The company is searching for international partners to distribute or commercialize its product under a commercial or distribution agreement. License agreements are also possible.



The company was established in 2014 and has grown constantly since then. It is deeply specialized in nature based solutions, through the integration of nature and architecture. The Spanish SME has developed different systems for vertical gardens, green roofs, natural pools and other green tools.

The company has developed a system to transform conventional existing pools into natural pools. This system performs water purification by natural means: using aquatic plants and other beneficial and non-dangerous microorganisms for people who carry out the necessary processes of the nitrogen cycle. Natural pools base their operation on the activation of the nitrogen cycle: Firstly, it promotes the appearance of beneficial bacteria that transform ammonia into nitrate through a biological filter. Then plants carry out a nitrate absorption process by removing these nutrients from the water. As a consequence of that the use of chlorine or any other chemical product is unnecessary in these natural pools.

The system components are: draining sheet, selected expanded clay layer, selected porous gravels, acuatic plants selection, pump equipment and complementary filter. It has been tested and executed in real customer cases. The company advise, design, and provide all the required materials of the product, and offer supervision and follow up of the complete system.
