About Us

The management team at Lotus Filter Systems S.L. has more than ten years of experience in the field wastewater treatment using Floating Wetland Treatments (FWT) systems. During this time they managed over 150 installations and have used their experience gathered from these installations to synthesize a number of wetland and conventional wastewater treatment technologies into one technology that is totally “Green”, cost efficient and sustainable.



Lotus Technology


Lotus technology uses a unique means of growing aquatic plants in a body of wastewater till they develop their roots and rhizomes into thick floating mats. These mats, along with specially produced biological and hydrological curtains, produce a great amount of oxygen and serve as a stable and durable support for the creation of biofilm upon which waste consuming bacteria can build their colonies without being washed out of the treatment areas. In this highly enriched environment bacteria are provided with the necessary oxygen to work at their optimum metabolic performance digesting vast amounts of waste naturally and economically. Thus, whether the source of the wastewater is municipal, industrial, commercial, agricultural or petrochemical, Lotus technology can be applied in a simple and economic fashion.


The component technologies incorporated in Lotus Filter Systems routinely treat waste water in which nitrogen, phosphorus, and pathogenic organisms such as bacteria, viruses, protozoa, and heavy metals such as cadmium, copper, chromium, lead, mercury, selenium, and zinc, are present. Because of its efficiency Lotus Filter Systems are being projected for the removal of heavy metals and pathogens from highly polluted rivers to provide drinking water in underdeveloped areas where electricity is unavailable, for the removal of stormwater pollutants and for the remediation of lakes and rivers.


Since Lotus installations require nothing more than the energy from the sun and a little wind they are very cost effective and have a virtually unlimited life span. They require very little energy to operate, need simple low-cost civil engineering, and have very low maintenance and operations costs to establish treatment facilities that are pleasant looking and ecologically functional.
