Technology that purifies 99 percent of mucilage-causing waste


Efforts are continuing to clean the mucilage, which can be seen in various parts of the Marmara and sometimes covers the bottom and surface of the sea.

The Port Authority, Coast Guard Command, Agriculture and Forestry Directorate and municipalities support the cleaning works within the scope of the “Marmara Sea Protection Action Plan” of the Ministry of Environment and Urbanization.

In addition to cleaning studies, many researches and studies are carried out to solve the causes of mucilage.

Membrane filters with nanotechnological method are used locally and nationally within ITU, at Agva Wastewater Treatment Plant in Istanbul, in the treatment and recovery of textile industry waste water, in the treatment of dairy industry waste water, in the treatment of strong waste water such as garbage leachate and in package waste water treatment plants.

It is stated that the membrane bioreactor technology provides 99 percent success in the treatment of domestic and industrial waste.

prof. Dr. İsmail Koyuncu told Anadolu Agency (AA) that water mobility is very low due to the fact that the Sea of ​​Marmara is a closed sea.

For this reason, Koyuncu stated that the balance of entry and exit in the Marmara Sea should be controlled very well and said, “The pollution load in such closed water environments should not exceed the assimilation capacity. For this reason, phytoplankton-type creatures in the marine environment at the moment feed on excess nutrients and grow and reveal mucilage.

“Household and industrial wastes are a big problem in pollution”

prof. Dr. Koyuncu underlined that the pollution load in the Marmara Sea, which is a sensitive environment, should be well controlled.

Stating that the single pollution in the Marmara Sea, namely the pollution given to domestic and industrial waters and the marine environment, poses a major problem, Koyuncu said:

“These domestic and industrial wastes need to be brought under control. In this way, we can reduce the pollution load and bring the mucilage problem in the Marmara Sea under control in the medium term. Membrane technologies are very important in terms of reducing and zeroing carbon, nitrogen and phosphorus pollution in domestic and industrial waste waters given to the marine environment. Membrane bioreactor technology is currently used in many places in our country and in the world. We also produce membrane filtration modules locally and nationally at MEM-TEK within ITU. We have now put it into mass production. Membrane filters are very small at the nanometer level, produced from polymeric materials They are filters that act as selectively permeable membranes with pores.”

Noting that the costs are reduced after this technology is produced in Turkey, Koyuncu said, “We are able to treat wastewater at a reusable level with membrane bioreactor technology. It is possible to apply the membrane bioreactor technology we produce within ITU in the sensitive region of the Marmara Sea and to control the pollution load. Membrane bioreactor technology is domestic and It provides 99 percent success in the treatment of industrial wastes.

Emphasizing that it is important that membrane bioreactor technology can be produced in Turkey, Prof. Dr. Koyuncu said, “If there is a demand, it is possible to use this technology in all wastewater treatment plants in the Marmara basin at the desired capacity.”

“A suitable technology for the Marmara basin”

prof. Dr. Koyuncu explained that the membrane bioreactor technology takes up one fourth less space than conventional treatment technologies.

Explaining that the population density is high in the Marmara Sea, Koyuncu continued his words as follows:

“Therefore, it is important that such treatment technologies take up less space. In addition, membrane bioreactor technology produces less sludge. This is important for the treatment plant. The application of membrane bioreactor technologies that produce less sludge will be a very suitable technology for the future-sensitive Marmara Basin. “The costs are 1/2 lower with products imported from abroad. In addition, since the technology is domestic, it is a preferred choice for municipalities as it has the opportunity to provide fast technical service in case any maintenance and repair is required.”

ITU Rector Prof. Dr. İsmail Koyuncu added that it is important to be able to recover the nitrogen and phosphorus in the treated water while treating the wastewater, and that nitrogen and phosphorus can be used in many different ways in fertilizer quality rather than being released into the sea with membrane bioreactor technologies.
