Pumps for hazardous materials handling areas of self service stations are still scattered in the country, generator room, engine room of the small vessels, etc. are installed inside buildings against big is the risk of fire extinguishers are installed only. These facilities are in severe climate change because it is an open space area, as well as a water based fire extinguishers may not be suitable for that type of gas extinguishing system is also adaptable. This study features a compressed air port operation principles and characteristics, equipment, fire extinguishers, which can minimize the casualties and property losses from fire against hazardous substances in small business, design requirements, domestic contain fire extinguishers laws and foreign Compression Four fire extinguishers through the air and foreign regulations comparative analysis of the compressed air port installations such as fire extinguishers and applied to study the measures to be included are fire extinguishers installed in the country. Climate change is a big country review In winter, water based fire extinguishers are also concerned about the freeze, but compared to the foreign installations were exploring ways to work in the country. CAF is especially preferred that the fire extinguishing performance and to demonstrate the protective space as there is a risk of frost risk significantly less compressed air port digestion plant.

The objective of this study was to investigate the response characteristics and performance of a biofilter in the removal of ammonia, as a malodor compound. A trickle-bed type biofilter was applied for this study, and operated at the ammonia loading rate of 0.97-15.52 g/m3·h. The results of the experiment indicate that the critical loading rate of ammonia to the biofilter was 10.7 g/m3·h and the elimination capacity was 11.6 g/m3·h. The analysis of nitrogen mass balance in the reactor indicates that inlet nitrogen as gas phase was converted through the biofilter into NH4 + (41.5% by mass), NO2 - (43%), and NO3 - (15%) as the available form of nitrogen in the effluent liquid. Free ammonia concentration in the effluent liquid was estimated as being in the range from 0.14 to 2.93 mg/L (average 1.7 mg/L) during the experimental period.
