TREATMENT SYSTEMS FOR ULTRA PURE WATER PRODUCTION

TREATMENT SYSTEMS FOR ULTRA PURE

WATER PRODUCTION

Generalities

Ultrapure water (also UPW or high-purity water) is water that has been treated to the highest levels of purity for all contaminant types, including : organic and inorganic compounds, dissolved and particulate matter, dissolved gases, etc..

A wide variety of industries & applications including food,

cosmetic, pharmaceutical, optic, microelectronic or

combined-cycled power generation use UPW in their process.

A typical UPW production system has three stages:

A pretreatment stage for elimination of physical impurities, organic compounds and color ;

Generally consisting of ( but not limited to ) media ( MM ) filtration, activated carbon ( AC ) filtration, microfiltration or ultrafiltration ( UF )

A primary stage to further purify the water ;

A single or double pass reverse osmosis ( RO ) system which removes an important part of dissolved material and microbiological activity

A polishing stage, the most performing part of the treatment process ;

Deionization ( DI ) or electro-deionization ( EDI or CEDI )

Features

Our systems are custom-designed and manufactured according to relevant European norms, based on a range of factors including ;

the characteristics of the available feed water, redundancy and the quality require-

ments for final product water.

• All pressurizing units consist of AISI 316 L or higher quality material for critical parts
• Efficient pretreatment by combining successive filtration equipment
• Complete corrosion resistance ;

FRP ( Fiber Reinforced Plastic ) or AISI 316 L cartridge filter housings

FRP media filter tanks

FRP membrane pressure vessels

• High performance system units ;

Superior quality TFC Polyamide RO membranes with high rejection

Superior quality CEDI modules generating mixed-bed quality deionized water without the use of chemicals

• Latest technology for final polishing stage ;

CEDI uses a reaction/transport mechanism to remove ions through resin under influence of a DC field

• Fully automatic operation by the use of an industrial PLC and touch screen HMI

Optional Features :

– Pre-installation of the equipment on stainless skid with complete piping and cabling
