Reusable construction materials

Reaction due to contaminants, e.g. in reusable containers or in transfer pipelines. Reaction with construction materials. 

Many users of large amounts of water treatment chemicals have product supplied in either semi-bulk or bulk containers (tanker trucks). Semi-bulk usually means the supply of intermediate bulk containers (IBCs) or tote bins. These are reusable, stackable containers, holding 120 to 330 gal. (450 to 1250 1). One ton semi-bulks are very common. They are available in a variety of construction materials and configurations. The customer may hold two IBCs on-site for every product employed, with one IBC being exchanged as soon as it becomes empty. Alternatively, the IBC may be used to supply small day tanks. 

Temperature control Adequately sized pressure relief Elimination of contaminants, including metallic residues, from process streams and equipment Selection of materials of construction compatible with the chemicaKs) in use, properly cleaned and passivated Elimination of ingress of reactive chemicals, e.g. water, air Date labelling and inventory control in storage Cleaning and inspection of reusable containers, tankers etc. before refilling ... 

Composites are also used extensively where light but very strong materials are needed such as in the construction of the new Boeing 767 where composites play a critical role in the construction of the exterior. They are also used where excessive high heat stability is needed such as in the reusable space vehicle (Figure 18.7). 

During collection, storage, and transportation, use containers constructed of materials compatible with the treatment methods utilized. Ensure the use of burnable single-use containers for waste destined for incinerators. Containers destined for steam sterilizers should allow proper treatment of the waste. Decontaminate reusable containers after each use using only approved methods. Never reuse containers unless decontaminated and before use remove all medical waste labeling.
