Phytodepuration

Closed cycle phytodepuration systems are installed at gas compressor stations for the comprehensive treatment of domestic wastewater produced onsite. These systems help to eliminate this type of discharge because wastewater is treated and completely absorbed by planted vegetation prior to the separation of solid sediments

Phytodepuration is a system that uses shrubs, plants and flowers instead of traditional purifying systems.

The effectiveness and functioning of the purification system essentially depends on the behaviour of the plants used. Plants have an elevated capacity to absorb and use certain elements, thus preventing the contamination of surface or subterranean water bodies; they also promote microorganisms in the soil that attack and destroy a good portion of organic pollutants.

To function properly plants need an environment that ensures adequate light, water, thermal insulation and the chemical elements needed for organic synthesis. Land is therefore an essential component of this environment as it supports and nourishes plants. In phytodepuration systems, natural habitats for cultivating plants are artificially reconstructed; pollutants are removed through complex biological and chemical-physical processes, an essential part of which is the synergy between plants and the microorganisms that flourish in their habitats.
