“…Activated charcoal or activated carbon is a material resulting from the pyrolysis process of charcoal at a temperature of 600 -900 o C [11]. Activated carbon has a surface area of 300 -2000 m2/g [12]. The particle size of activated carbon in powder form (Powdered Activated Carbon) is <0.188 mm and the particle size of granular activated carbon (Granular Activated Carbon) is 0.2 -5 mm [13].…”

One method to reduce the content of heavy metal mercury in wastewater is adsorption. Several media materials have been investigated for use as adsorbents. In this study the characteristics of the palm kernel shell were analysed so that it could be used as an adsorbent. In addition, it also analysed its ability to reduce levels of mercury in wastewater. Palm kernel shells were activated using two types of activators, namely H3PO4 and NaOH and variations in adsorbent sizes of 50 mesh and 100 mesh, as well as variations in contact time for 30 and 60 minutes. Based on the results of this study, it was obtained that the characteristics of the adsorbent of palm kernel shells with the use of H3PO4 and NaOH activators met the quality based on SNI 06-330-95. The adsorption efficiency of mercury (Hg) removal can reach 99.7% with a contact time of 60 minutes and an adsorbent size of 100 mesh activated by NaOH.

“…To reduce demand of bleed air on the engine for cabin thermalization and pressurization, aircraft manufacturers implemented an air recirculation system, which mixes bleed air with air recirculated from the cabin with a recirculation fan (Figure 1). Nowadays, on most commercial airliner models, the air flowing in the cabin comprises between 30% and 50% of recirculated air 1 . Modern aircraft recirculation systems include a filtration unit which comprises a high‐efficiency particulate air (HEPA) filter with stated single‐pass PM removal efficiencies up to above 99% 2 .…”

“…The first high‐efficiency filtration system on a commercial aircraft ECS was implemented in 1994 on an Airbus airliner 1 . According to the Federal Aviation Administration (FAA Title 14) and the American National Standards Institute (ANSI/ASHRAE standard 161), air filters are now mandatory to be mounted on all commercial aircrafts.…”

“…Today, modern airliners ventilation systems are equipped with HEPA filters as standard 27 . The HEPA cabin air filters definition in aerospace industry is based on a minimum removal efficiency of 99.97% when tested using a DOP challenge (mean size 0.3 µm, according to ASTM publication D 2986‐95—Boeing criteria) or 99.99% when tested with a sodium chloride challenge (mean size 0.58 µm, according to British Standard BS.3928—Airbus criteria) 1,28 . Typical ECS HEPA filters dimensions are roughly about 60 cm by 60 cm, with a 15–20 cm thickness and weight approximately 3–6 kg.…”

Exploring the potential of electrostatic precipitation as an alternative particulate matter filtration system in aircraft cabins

Over the last few decades, significant efforts have been made by aircraft manufacturers to reduce the overall energetic consumption of aircraft engines. Besides providing thrust and electric power, an engine must also provide pressurized fresh air to the cabin. A substantial part of the outside air compressed by the engine is "bled" off the engine and passed through air conditioning packs to be cooled and supplied to the cabin. This "bleed-air" pressurizes and heats the cabin to overcome extreme external conditions (low temperature and pressure at high altitudes). As passengers and crew are confined in the relatively low volume of the aircraft cabin, a high flow of fresh

“…Given the large number of passengers in an aircraft cabin, high concentrations of particles (dust, thin fibers, skin particles), bacteria (up to 30 000 bacteria per minute per passenger can be released from skin scales into the cabin environment), fungi, viruses, and volatile organic compounds (VOCs) carrying odors are encountered. Thus, exposure to one or several indoor air pollutants may lead to various adverse health effects such as headaches, loss of memory, dizziness, etc.…”

Air quality on aircraft cabins has become a major public health issue due to the increasing number of air travels since few decades. Exposure to volatile organic compounds (VOC) and micro-organisms is a major concern for human and animal welfare in indoor confinements and especially in aircraft cabins. Here we present an innovative air purification system based on the association of UV-C and photocatalysis. The SAVAB project is aiming at a higher decontamination degree of aircraft cabin air, thus improving health and comfort standards of aircraft crew and passengers. We show a degradation of irritating/noxious VOC such as formaldehyde, toluene, benzene, acetone, which are major pollutants of the aircraft cabins according the NF EN 4618 standard. In the same study, we also demonstrate the inactivation of pathogenic Influenza virus, adenovirus and pathogenic bacteria such as Legionella pneumophila, Burkholderia cepacia, Streptococcus pneumoniae, and Pseudomonas aeruginosa. This innovative system demonstrates its ability to improve air quality in indoor confinements of travel-motorized units such as aircraft cabins and could be applied in hospital environments.
