YOGYAKARTA - The water mist system will be used by the DKI Jakarta Provincial Government as an effort to overcome air pollution in the capital. The provincial government plans to install these tools for high-rise buildings, especially government-owned buildings. So what is a water mist system that is said to reduce air pollution?

Asep Kuswanto, Head of the DKI Jakarta Environmental Agency, appealed to the management of the multi-story building to implement a water mist system from above the tall building. Kuswanto conveyed the plan after testing the water mist kit in Pertamina Building, Central Jakarta.

"We sprayed water fog from above the Pertamina building and measured directly with a PM monitor 2.5. It turns out that (water fog suppression) was able to reduce PM 2.5 levels around the building," said Kuswanto on Monday (28/8).

Kuswanto assessed that the use of a water mist generator is more effective in dealing with air pollution than by spraying water on the road. So what is a water mist system and how does it work?

Water migration system is a water fog sprayer that is usually used for firefighters. This tool is generally used as a protection of fire against buildings with water-sensitive materials and tools.

The water mist system technology was first installed in 1940 to protect the room (iron-iron) from the threat of fire. Over time this tool was also used as protection for various rooms, such as electricity, flammable liquid tanks, fuel storage, libraries, museums, historic rooms, underground systems, and others.

Some people think the water mist system is the same as a sprinkler fire extinguisher. In fact, there is a difference in the way the water mist system works, which is the size of the water sprayed from the nozzle. At higher pressures, the amount of water from the water mist system is limited.

The water mass system pressure size starts from 100 to 1000 psi. With higher pressures, it will generally produce volumes from larger sprays. In addition, water discharge is usually 50 to 200 microns in size. While on the sprinkler, the standard water size is 600 to 1000 microns. The smaller the size, the more efficient it will be to cool and control the fire.

For water supply on the water mist system, use a pipeline or tank system. Pipes and nozzles can be reduced when compared to the needs of the sprinkler installation. The way the nozzle works on the water mist system is the same as the sprinkler, which is to be active if there is heat from the fire. The size of the nozzle on the water mist system is lower than the sprinkler.

In the use of the water mist system, there are some tool controls. The fog that comes out can be governed by selection, a high-quality detector or detector using the VESDA smog technology system. But the drawback of this tool is the cost of its installation higher than the usual sprinkler.

Demikianlah reviewasi mengenai apa itu water mist system dan cara kerjanya. Diharapkan pemasangan water mist system di Jakarta bisa diterapkan dalam jumlah banyak mengingat banyaknya bangunan-bangunan bertinggah atau tinggi.
