Distillation has long been recognized as the most reliable method to generate sterile pyrogen-free water. This natural liquid-vapor-liquid phase process consistently remove impurities from water without the use of...
Pre-Treatment
The pretreatment includes all the process steps to prepare the water to feed the final water treatment steps that could be Reverse osmosis, Electrodeionization, Ultrafiltration and if WFI is required distillation.
The pretreatment is critical (even though often not given enough consideration) because if not adequate, it could cause problems to the final purification step.
Specifications
Design
The pretreatment will be developed depending on the final PW treatment selected; it will target the control or removal of the following main group of impurities:
- Turbidity and particulates
-
Hardness and metals
- Organics and impurities
- Oxidating agents
Configurations
The raw water analysis is the first step to achieve a successful water treatment plant.
Starting from this report we will design the Water treatment unit to meet your compendial PW or not compendial final water requirements.
The pretreatment system may include some of the following:
- Dualmedia filtration
- Cartdrige filtration
- Water softening units
- Chemical injection systems
-
Particulate removal filters
-
Ultrafiltration
-
Microfiltration
-
In-line Ultraviolets units
-
Antiscalant injection syste,s
- Heat exchangers
Skid construction features
Each ELETTRACQUA system is customized to meet our customers requirements, starting for example from room lay out to have the best installation solution. Several materials can be used at the pretreatment stage:
- PE-HD
- PVC
- PP
- AISI
