Professor of Soil Science at Ankara University. Dr. Günay Erpul and Agriculture and Forestry Expert Adem Bilgin’s article on the cyclic economic eco-swamp solution produced against mucilage formation was published in the European Journal of Environmental and Earth Sciences. Ecological swamp restores nitrogen and phosphorus in wastewater to the circular economy and reduces emissions of flue gases into the atmosphere.
The mucilage problem, which threatens the natural life in the Aegean Sea and the Black Sea, especially in the Marmara Sea, is on the agenda not only of our country but also of the world. Finally, on June 5, 
World Environment Day, Prof. from Ankara University Soil Science Department, about the invention of Agriculture and Forestry Specialist Adem Bilgin. Dr. The scientific article titled “Redefining Water Treatment: Identification of Wastewater Treatment Plants as a World System Problem and a Cyclic Economic Eco-swamp System to Challenge This Problem”, co-authored with Günay Erpul, was published in the European Journal of Environmental and Earth Sciences. Environment and Earth Sciences) was published. Turkish experts point out that in the article on the invention of mucilage formation and climate change, the solution is through a method inspired by nature and called eco-swamp.
“Heavy metal and microbes in the sewer burn into concrete”
Stating that billions of cubic meters of sewage water are purified every day in the world, resulting in sludge and flue gas, Adem Bilgin stated that this is a major ecological and even a worldwide system problem and continued his words as follows: “Treatment engineering should not only be analytical but also holistic. , that is, natural matter cycles and must be compatible with the law of conservation of mass. The nature-inspired and synthetic ecological technology, which I call the circular economic eco-swamp, includes vertical farming in the final water to go to the discharge of the wastewater treatment plant, and producing algae in plexi pipes before the discharge, thus extracting phosphate and nitrogen from the final water. The algae obtained are turned into sand and aggregate, which we call the smallest natural piece of soil, by swamping, mucilage formation and precipitation in artificial pools with flue gas from the bottom. These, in turn, are turned into concrete by mixing with the ashes obtained by burning the sludge produced after treatment. In other words, it copies natural marshes, which already have large carbon reserves in nature, in a controlled manner and turns them into terrestrial nitrogen, phosphate, carbon concrete and biomass. Heavy metals and microbes in the sewer burn into concrete. Since the system takes the sulfur of the flue gases and makes fertilizer and converts the remaining gases into biomass and concrete, the hydrogen sulfide that gives its smell to the natural swamps and is both toxic to humans and chemical corrosive does not occur. Regularly harvested algae and marsh products are packaged for various uses, especially in the fertilizer, cellulose, cosmetics and pharmaceutical industries. It also produces cement and hydrogen for the chemical industry. Algae production is already an issue suggested by the EU Biomass Strategy, especially for the circular economy and climate change, we go one step further and make soil from algae, tying carbon to the ground.” said.
“Phosphorus, which is a very big import item for Turkey, is in danger of running out on land”
Defining eco-swamps as ecological stops, Prof. Dr. Günay Erpul, on the other hand, said that the wastewater can be cleaned with the eco-swamp system and recycled into the circular economy before it is discharged to the natural waterways, rivers and seas. Erpul said, “Commercial fertilizers containing nitrogen and phosphorus are used more and more each day. These fertilizers, which cause large-scale chemically active nitrogen and phosphorus fluxes, have serious negative effects on human health and the environment. On the other hand, they are a non-renewable resource and for Turkey. Phosphorus, which is a very large import item in Turkey, is in danger of being depleted on land. Therefore, nitrogen and phosphorus gains and reuses are desirable in terms of nutrient cycling. At this point, eco-swamps offer very important opportunities for biological assimilation of nutrients. A wide variety of wastewater is used to ensure nutrient cycling and nutrient recycling in swamps.Waste waters from domestic, dairy, textile production, tanneries, etc. are the most common examples. These days, when we face the mucilage problem, especially in eco-swamps, plant and recycle phosphorus into nutrients by growing algae It turns out to be a very reliable method in the long run.”
Reminding that the prerequisite for sustainable agriculture is the efficient circulation of plant nutrients, Erpul concluded his words as follows: “Aquatic and sea-based ecosystems where cleaned wastewater is discharged to a certain extent will also benefit from these processes.
