Scrubber System Helps Reduce Bad Smell

Conflict between communities and industrial factories has continued to be an accumulated problem in many areas, especially, the complaints about air pollutions stemed from industrial factories because most of the production processes have usually created bad smell or pollution that will cause damage in various fields to the communities and the surrounding environments. However, there are a lot of factories not ignoring the rising problems and have been trying to find a solution whether in organizing the order of buildings, installing deodorizing devices, buildingwastewater treatment ponds including the design of scrubber system innovation to particularly remove particulates and/or gases from industrial exhaust streams to eliminate foul odors in the factories.

Scrubber system is anodor treatment process by using a solution for absorption in the case ofa smell with alkaline property: such as; ammonia, trimethylamine, to react with acid solution to acquire odorless compounds. In the event of an odor-caused substance with the acidic property: such as; hydrogen sulfide, methyl mercaptan, they can react with the alkaline solution to acquire odorless or less odor compounds. The scrubber system commonly used consists of two types: one is a vertical system using intake airflow through the bottom and outtake through the top and the other is an air cross-flow. At present, the air cross-flow system has become increasingly popular because of a less clog-up problem and the device is not too high which can be placed in low-ceilinged rooms. The system consists of the type in which a medium is placed inside to increase the surface of contact between gas and liquid and the type having no medium in which water sprayer is used to make a water curtain or high pressure air is used to spray water to cause the air and water to be exposed and the odorant substances in the air to dissolve in the water. It shall be cautioned that in using thissystem, the temperature of the treating air before being fed into the system must not be too high because it will cause a rising of the steam and reduce the absorption efficiency. In the event of a necessity, an air heat exchanger before the air is fed into the system may be required and that caution on the matter of the dusts should be exercised as they may cause a clog-up.

Exhaust air released from factories or any sources of origin may have an impact on the surrounding communities. It is therefore necessary to have an efficient air pollution treatment system suitable for the type of pollution such as particulates or gases. People handling air pollution treatment systems must have adequateknowledge and understanding on the fundaments and operations whether in the processing steps of designing, system calculations, construction and installation controls, working inspections as well as the directions on the use of the system to work properly.
