Biological Floating Island

Some man-made factors make the water quality of urban (landscape water) and natural water (such as rivers, lakes, etc.) decline, there are different degrees of eutrophication, and lose their proper ecological function. To ensure clear and clean water, it is necessary to control the content of pollutants such as chemical oxygen demand (COD), biochemical oxygen demand (BOD), total nitrogen (TN), total phosphorus (TP), an overgrowth of algae, and others in water.

Lifeasible provides a biological floating island construction service. We first analyze the water quality of your target water samples (measure water quality indicators), then apply the principle of soilless cultivation technology, put some targeted higher aquatic plants or improved terrestrial herbs and woody plants, using floating islands (i.e. floating body cultivation islands) as a carrier to build a biological floating island system, creating ecological environment conditions for the survival and reproduction of aquatic organisms and providing a new way for the ultimate restoration of water ecosystems.

Key technologies

Plants are the most critical factor for Lifeasible to build and make the biological floating island system work, so the selection and configuration of different plants is our key technology.

• First, we test the indicators of the contaminated water provided by the client and analyze the characteristics of the water samples.
• Then, according to the characteristics of the water sample, we select several suitable plants and initially set them up in the polluted water (we will simulate the state of the water sample provided by the customer).
• Finally, continuous real-time monitoring of many indicators such as COD, BOD, TN, TP, and ammonia nitrogen in the water is carried out to evaluate the effect of the system and adjust the plant configuration in time to achieve the optimal purification effect.

In addition to the direct provision of a biological floating island system, you can also choose your configuration plan as long as the biological floating island, we will also provide detailed parameters of the analysis results of simulation experiments, which you can implement in the field according to our plan.

You can place the constructed system on the water surface of the eutrophic water environment and enrich the harmful substances in the water through the absorption and utilization of plant essential elements such as N and P during the growth of plants and the adsorption of suspended substances in the water by plant roots and floating island substrate.

• Plant roots release organic secretions to promote the growth of inter-root microorganisms, thus accelerating the decomposition of organic pollutants by microorganisms.
• With the improvement of the water quality index, especially the substantial increase of dissolved oxygen (DO), the conditions are created for the proliferation of aerobic microorganisms in water. Through the further decomposition of organic pollutants and nutrients by microorganisms, the water quality is further improved.
• Eventually, through the form of the harvesting plant body, nutrients such as N and P in water and pollutants adsorbed and accumulated in the plant body and root surface are moved out of the water body, so that the pollutants in the water body are greatly reduced and the water quality is improved.

It has been proved that the biological floating island purification system provided by Lifeasible effectively removes organic pollution from the water, eliminates the phenomenon of water black odor, controls the outbreak of water wars, improves the transparency of the water body, and achieves certain landscape effects at the same time.
