1. Problem description:
The customer wants to use high hardness groundwater as raw water, By advanced EDI (Electric deionization) Technical treatment, Produce pure water that meets high standards of conductivity and hardness, For the production of baby hand and mouth cleaning wipes and family, Wipes for medical and other application scenarios.
2. Application scenario:
Infant care: The wipes should be soft, No stimulation, Can safely clean the baby's hands and mouth, Reduce bacterial transmission.
Household cleaning: Suitable for kitchen, Rest room, Cleaning of furniture and other surfaces, Need wipes with good decontamination ability and gentleness.
Medical use: Some medical Settings require high purity wipes for surface disinfection or patient skin cleaning.
3. Raw water quality and quantity:
type: Underground water
Water quality characteristics: High hardness, May contain more minerals, Suspended matter and trace organic matter.
Water requirement: On a production scale, The preliminary estimated daily water requirement is 24 Tons of (T/D) , Production needs during peak hours need to be considered.
4. Water quality requirement:
Electric conductivity: It needs to meet the ultra-pure water standard, Electrical conductivity below is usually required 0. 1 μS/cm.
hardness: Almost no hardness residue, Ensure that the wipes will not affect the use effect or precipitate due to water quality problems.
pH value: Close to human skin pH value, around 4. 5-6 among, To reduce skin irritation.
Special index: alcohol-free, fragrance-free, Non-fluorescent agent, No chemical additives, Ensure product safety.
5. Water requirement:
According to production line design, Water consumption per hour is approximately 3 Tons of (T/H)
6. Device installation environment:
The construction site should have a stable water passage, Ensure smooth flow of raw water supply and pure water discharge.
The power supply must meet device running requirements, Have a backup power supply in case of power failure.
The installation site depends on the device layout, Operation space and maintenance channel, Total area approx 10 Square meter.
Design in accordance with the following national and industry standards:
"Standard for drinking water" GB5749-2022
"Water quality standard for drinking water" CJ94-2005
"Standard for reverse osmosis water treatment equipment" GB/T 19249-2017
Design principles include:
Ensure that the treated water meets the strict requirements of all application scenarios.
The system runs stably and reliably, Easy to maintain and manage.
Energy saving and consumption reduction, Reduce operating costs.
Environmentally friendly, Consistent with the concept of sustainable development.
System introduction:
This system adopts preprocessing+Reverse osmosis (RO) +EDI Tertiary treatment process, Ensure that groundwater is converted to high purity EDI Pure water.
Process flow:
Pretreatment stage:
Multimedia filter: Remove suspended solids from water, Large particles of impurities and some organic matter.
Activated carbon filter: Further adsorption to remove organic matter from the water, Residual chlorine and other chemicals.
softener (selectable) : For high hardness groundwater, Softened by ion exchange resin, Reduces the hardness of water.
Reverse osmosis (RO) phase:
The pre-treated water is fed into the reverse osmosis membrane assembly by a high pressure pump, The selective permeability of the membrane is used to remove most dissolved solids from the water, Ions and microorganisms.
EDI phase:
Reverse osmosis water enters EDI cell, By the action of an electric ion exchange membrane and electrode, Further remove residual ions from the water, Meet the ultra-pure water standard.
EDI The advantage of the technology is continuous operation, No chemicals required, And can retain the original purity and activity of water molecules.
System advantage:
Efficient removal of impurities: Through a multistage processing process, Effective removal of suspended matter in raw water, Organic matter, Ions and other impurities, Ensure clean water.
Energy saving and environmental protection: Reverse osmosis and EDI Technology combination, Reduce energy and water consumption, Achieve green production.
Stable and reliable: High degree of system automation, Stable and reliable operation, Reduce human error.
Easy to maintain: Modular design, Facilitates routine maintenance and troubleshooting.
Flexible adaptation: Water production and quality standards can be adjusted according to customer needs, Meet the requirements of different application scenarios.
