The PMA study aimed to establish the safety and performance of the CALCIVIS imaging system determined through the correlation of the luminescent images produced by the system and a clinical assessment of active demineralisation
associated with caries lesions.
A simple two-stage ion exchange demineralisation
system can produce purified water of better than 1 [micro]S/cm conductivity which is equivalent to about 0.5mg/l total dissolved solids (TDS) whilst RO permeate is typically about 5[micro]S/cm (about 2mg/l TDS), so ion exchange wins that round.
Dave Clark, commercial & engineering project manager at Veolia Water Technologies explained that Veolia designed and constructed a bespoke water treatment system consisting of pre-treatment by coagulation, high rate clarification and filtration followed by demineralisation
by reverse osmosis and ion exchange.
Therefore, the present in vitro study aimed to evaluate the contribution of acidic medicine on bovine dental enamel subsurface demineralisation
under pH cycling conditions.
Heat Exchange Products also take care of process water systems incorporating filtration, softening, demineralisation
or reverse osmosis as well as "stripping-water plants", producing clean water that does not block spray-nozzles.

Metito will install a conventional demineralisation
plant featuring the latest industry equipment including a degassed water tank, strong base anion exchanger, chemical injection pumps, air blower systems and a regeneration system utilising bulk chemicals.
The UAE based company will install a conventional demineralisation
plant featuring the latest industry equipment, including a degassed water tank, strong base anion exchanger, chemical injection pumps, air blower systems and a regeneration system that utilises bulk chemicals.
Efficient ion exchange demineralisation
methods therefore are required in this so-called "polishing stage."
Sometimes dentists can identify this demineralisation
by seeing a change in the colour of the tooth, or by looking at x-rays.
effect of orange juice may be lessened by the buffering capacity of saliva."
Metito has been sub-contracted by Samsung C & T Corporation to design, manufacture, supply, install and commission a demineralisation
plant for the Shuweihat S2 Independent Water and Power Project in the UAE.
It can lead to demineralisation
of the tooth enamel which can result in discoloration, sensitivity and expensive dental work such as veneers.
One of the facilities, a mixed bed demineralisation
plant, will process 2 x 90 cu m per hour of high-purity water.
