The condition of river and lake water that is dirty or polluted in various cities across Indonesia, especially in Jakarta encourages the Indonesian Institute of Sciences-LIPI to find a solution to solve the problem. The LIPI researchers have proposed a solution with their artificial tool called ‘LIPI Ultrafine Bubble Generator’-LUTOR. They said that this tool is able to clean the water of the lake or river by making the bacteria located at the bottom of the lake work more actively. Head of LIPI Instrument Development Center, Anto Tri Sugiarto at the World Water Day commemoration in Jakarta on Thursday (March 22^nd) explained that this tool works by creating tiny oxygen bubbles in the water.

“Nano bubbling is so simple like this; if at home, we have an aquarium with some bubbles inside. The bubbles are large and then loose upwards. So the oxygen, the air has not been taken in the water. If we shrink again into micro bubbling, it is also formed but afterwards, it is released, too. But if we make Nano bubbling, a very small size of oxygen will be very stable in the water because it is so small and stuck by water pressure,” said Head of LIPI Instrument Development Center, Anto Tri Sugiarto.

Anto Tri Sugiarto added, the high levels of oxygen in the water make bacteria work faster, and river or lake water will become much clear, because, the bacteria will eat a variety of organic waste contained in the bottom of the river or lake. For its use, LUTOR only needs to be placed in a river or lake. The LUTOR will take oxygen from above the water level and then inject it into water in the form of small bubbles of oxygen or Nano bubbles while working. (VOI/Rezha/Rhm)
