Waste water treatment

Environment impact assessment is prerequisite requirement for any new investment project in Vietnam, and how to treat the waste of the industrial process including wastewater to conform to environmental legislation at a reasonable cost and with environmental friendly solution is of the top concern.

Water treatment consists of several mechanical and chemical processes that aim to remove water contaminants or reduce their concentration in order to make water more acceptable for a desired end-use.

Air Liquide Vietnam with industrial gases can offer alternative solutions to the traditional water and waste treatment processes. With the support of 35 years of experience and references in water treatment from Air Liquide group, we are confident to introduce ASPAL™  solution – a reliable and cost-effective technology providing environmental benefits in competitive manners to treat and recycle water. ASPAL™ leverages know-how in:

  • pH control
  • Biological and activated sludge treatments
  • Odor control
  • Disinfection
  • Scale prevention

Our expert team will do site survey and carry out the solution implementation on site to deliver customers’ expected performance.

N2 for wave & reflow soldering

Electronic components and products

Sparked by innovation in the assembly of electronic components, electronics have become smaller, lighter and less expensive. Currently, oxidation reaction, poor wettability and high peak temperature during soldering of printed circuit boards create harm to electronic solder joints. To offset these effects, using nitrogen to inert the atmosphere during soldering has become a globally accepted practice within electronics manufacturing.

Nitrogen atmosphere improves the wettability of solder, reduces the degree of oxidation, and accelerates the speed of soldering reaction. Whatever our customer need to inert their wave soldering equipment and simultaneously decrease costs, Nexelia for wave soldering is the optimal choice.

Nexelia for wave soldering is a total retrofit solution to generate and carefully maintain an inert atmosphere during the wave-soldering process.

Food & Beverage

Food manufacturers are faced with significant challenges. First and foremost, they must meet the nutritional needs of a growing global population. Second, they are under pressure to satisfy the demands of increasingly urban consumers, providing ready-to-eat and wholesome products with fewer chemical additives and preservatives. They must do this while adhering to stringent food safety rules and coping with strong competition. In consequence, manufacturers are under pressure to innovate and launch new products in shorter delays.

With strict regulations and constantly evolving consumer behavior, the beverage market is structured around three central challenges. Most importantly, food safety must be guaranteed, but the quality of taste and nutritional benefit must also be assured. Finally innovation is used as the lever for company differentiation thus responding to consumer demand for new products.

Air liquide food grade nitrogen - ALIGAL™ - is produced in conformity with Air liquide standards and procedures for foods applied in European countries and is also certified in Vietnam by MOH (Ministry of Health) for conformation to food safety regulations, which are suitable both for MAP (modified atmosphere packaging) and beverage.
