PureTech develops individually designed and engineered pre-treatment systems to treat the local water in local conditions.

As market leaders in the design and delivery of raw water pre-treatment units, Puretech has installed units all over the world, each one individually designed and engineered to treat the local water in local conditions to provide the first step of treatment and protection to the water purification technology.

The production of water for pharmaceutical use (WPU) requires potable water. According to the World Health Organisation (WHO), the purification of the water to obtain potable water depends on the source of raw feed water for the system. The feed water available for the production of pharmaceutical waters usually contains different concentrations of solids in suspension and contaminants which must be removed before feeding the equipment for pharmaceutical water production. These contaminants or compounds are usually oxides of iron and manganese, calcium, magnesium, solids in the suspension of various sizes, soluble salts, organic compounds etc..

The retention devices commonly used in pre-treatment are:

  • Multimedia filters
  • Duplex softeners
  • Particulate filters
  • Dosing of chlorine, NaOH, metabisulphite.
