  The salt spray (or salt fog) test is a standardized and frequently used  corrosion  test method, used to check the corrosion resistance of materials and surface  coatings . Usually, the materials to be tested are metallic and finished with a surface coating that is intended to provide a degree of  corrosion  protection to the underlying metal. Salt spray testing is an accelerated corrosion test that produces a corrosive attack on coated samples in order to evaluate the suitability of the coating for use as a protective finish. The appearance of products of corrosion ( rust  or other oxides) is evaluated after a predetermined period of time. The testing apparatus is composed of a closed testing chamber, where a salt water (5% NaCl) solution is atomized by the means of a spray nozzle that uses pressurized air. This creates a  corrosive  environment of a dense fog of salt water in the chamber so that test samples expose...

  Sewage is the waste generated from residential, institutional, commerc ial and industrial establishments. Due to the hazardous impacts of municipal, industrial and hospital wastewater on water, soil, air and agricultural products, wastewater treatment and the proper disposal of the sludge produced are indispensable from an environmental safety point of view. Moreover, due to the global water shortage crisis, water from wastewater treatment needs to be reused increasingly in the near future. Reuse of sewage is the most sustainable and long-term solution to the problem of water scarcity. Sewage Treatment Plants (STP) treat the sewage and waste water to produce a cleaner, more environmentally friendly effluent that is safe for disposal, gardening/agricultural use or domestic use in toilets, etc. Physical, chemical, and biological processes are used to remove contaminants and produce treated wastewater (or treated effluent) that is safer for discharge into the environment or fo...

  A dehumidifier is a machine that removes excess moisture from the air. An industrial dehumidifier is built to be transported and used in several hard-wearing locations. Commercial and industrial dehumidifiers will reduce mold, condensation dripping from pipes or windows, and eliminate musty smells. APPLICATIONS WHERE DEHUMIDIFIER MACHINESARE USED: PHARMACEUTICAL Moisture control is a great concern in the pharmaceutical industry from product manufacturing to packaging, and from shipping to storage. Some applications for humidity and moisture control in pharmaceuticals relate to microbiological considerations, while many applications relate to processing in order to achieve correct moisture levels that will facilitate the filling of capsules, tablet forming, and packaging. For example, gelatin capsules are often monitored closely for moisture content to allow them to be sufficiently supple for filling without cracking or breaking in the manufacturing proces...
