Nanhu, located in the center of Yueyang City, Hunan Province, is a tourist and leisure Lake area (12 square kilometers, 18000 mu). It is surrounded by green trees, surrounded by footpaths, with beautiful scenery. It is a city card of Yueyang. However, since 2008, cyanobacteria began to appear in Nanhu Lake, and they have erupted every year. In the past 12 years, Yueyang government has tried various methods to prevent the recurrence of algal blooms, but they all ended in failure.
Before the beginning of the control of the blue-green, the cyanobacteria in the South Lake had begun to appear local bloom and eventually large-scale outbreak. 48 hours after the first use, the biomass of cyanobacteria in the South Lake dropped below the dangerous level and continued to improve in the following days. Huwei is a kind of floating sustained-release preparation, which can be used for local treatment of harmful algal blooms. The satellite image processed by the satellite remote sensing system huweikan developed by the company can see that the cyanobacteria level measured in the lake (in situ) dropped significantly within 24 hours, and the result can also be observed by the naked eye. The satellite monitoring system of yulv can intervene before the outbreak of cyanobacteria (invisible to the naked eye), so as to ensure no cyanobacteria bloom.
The floating and slow-release products of Huwei are for local and selective control of harmful algal blooms. Huweis product particles will be concentrated by wind and water in the place where algae bloom gather. In short, the product will automatically find cyanobacteria and kill them. The product can be applied locally, easy to operate and can be used in all water bodies, regardless of the size or shape of the water body. In addition, Huwei will cause selective programmed cell death in cyanobacteria population, which will lead to the collapse of cyanobacteria bloom in a short time, while other beneficial algae will not have such a reaction, so that they can quickly occupy the niche and restore the water ecological balance.
The treatment of South Lake is one of several emergency intervention projects deployed in the world after Weilvs emergency treatment of South Africas rodpratt reservoir (4.4 square kilometers, 6600 mu) in February 2020.
We are proud to protect the worlds rarest and most basic element of water, said Eyal Harel, CEO of wellgreen. The successful management of Weilv in the South Lake has also given Yueyang citizens a South Lake without cyanobacteria, and also brought new hope for many lakes in China that are plagued by cyanobacteria.
Our technology continues to attract the attention of Chinas environmental protection industry. Through this treatment, we have seen Yueyangs determination and efforts to control cyanobacteria. We are very happy to cooperate with great lakes, they have made a lot of efforts and contributions to this project, and they have recognized our technology and products from the very beginning, said Wang Pu, general manager of yulv Greater China. I hope we can have more in-depth cooperation through this project. About blue green water technologies, Ltd., a water environment technology company headquartered in Tel Aviv, Israel, is committed to developing solutions to water environment related problems. At present, there are two products on the market, Huwei blue and Huwei oxygen. Both of these products are used for the control and remediation of cyanobacteria bloom. Weilv is developing and improving a new satellite image monitoring system to support the competent authorities to identify and intervene in the early occurrence of cyanobacteria bloom in time, so as to avoid the serious consequences of the overall outbreak of bloom.
