At the time of acid introduction in the demineralisation
process, the existing collagen fibers in bone will be swelled, therefore the internal cohesion properties of the collagen fibers will decrease.
The system supplied by Aquatech will include three Multiple Effect Distillation with Thermal Vapor Compression (MED-TVC) units, each with a net capacity of 5,352 m3/day, three Fractional Electrodeionisation (FEDI(R)) demineralisation
units, each with a capacity of 3,360 m3/day of ultrapure water for boiler feed, and two remineralisation dosing skids for the production of service water and potable water.
