Introduction

Ornate Naturale is proud to introduce a new Water Treatment System under the brand name AQUADION in the market that is ideally suited for Drinking water applications. This is a new generation of water treatment system that can treat ground or surface water containing high dissolved salts to produce clean potable water that meets WHO standards.

Traditionally ground water treatment is done using Reverse Osmosis Technology. This technology wastes lots of water during treatment, uses more power and chemicals and has a high operating cost for delivering drinking water.

AQUADION is an excellent alternative to this technology. This is a high recovery system where water wastage is just 20% as against 70% from a RO system. It does not use any chemicals, consumes less power and has the lowest operating cost for treating water when compared to any system in the market today.

AQUADION is based on a technology called Capacitive Deionization (CDI). This innovative technology is used to desalinate water without using resin or membrane filters. It does not require chemicals to treat water and uses less power to separate salts in water.

The unique features about this product are :

Low water wastage : Compared to conventional RO systems that waste more than 50% of water, the maximum water wastage in AQUADION is 20%. This results in long-term conservation of ground water.

Low Operating Cost : AQUADION uses no chemicals and has low consumables for operation. It consumes less power and the total cost of producing treated water works at less than 5 paise per liter.

Simplistic Operation : AQUADION has a built in controller that automates the working of plant in typical Indian conditions. There is no major skill required to operate the plant. The system can be managed and operated by local resources where AQUADION is installed.

Handles Multiple Contaminants in Water : AQUADION reduces all dissolved salts like Calcium, Magnesium, Fluoride, Nitrates, Arsenic and other contaminants typically found in ground water – but yet retains the desired levels of minerals required for human body.

Environment Friendly : AQUADION does not use any chemicals for treatment. The drain water coming from the system does not contain any chemicals that are hazardous to environment. This ensures safe release of water back to the environment.

Product Overview

AQUADION is based on a technology called “Capacitive Deionization”. Capacitive Deionization is a technology for removing salinity from water.

The system takes out the following salts (not limiting) in a single process. By controlling the flow and managing the contact time, it is possible to ensure the required salts be retained in the output water that is good for consumption.

Table below shows some examples of salts and metals removed using AQUADION

Working of CDI

CDI Cells uses different coupled electrodes contained in a pressurized container, supplied with direct current at a potential difference of 1.6 Volt. The electrodes are placed at a distance at an order of magnitude of 0.1mm.

By powering the electrodes, an electrostatic field is created. The salts contained in the water, having an electric charge, will be attracted by the electrode with opposite charge.

Operating at low voltages, electrolysis and gas production will not occur. The result is the partial or total demineralization of the water (Step 1 in picture below)

Once the electrodes are saturated with ions, the system will automatically short-circuit the electrodes (Step 2 Picture below) releasing the ions and after that will reverse the polarity and move all the salts to the drain (Step 3 picture below) in a small amount of water (around 20% of incomeing water). At the end of step 3, electrodes are regenerated, the polarity is reversed back to normal and the cycle starts again.

The whole process takes place automatically at a frequency of about one minute.

Step 1 Ion removal : When Water passes between the electrodes, the ions get attracted to opposite charged electrodes. The water void of these salts and metals come out of the system

Step 2 Regeneration : With more and more ions sticking to the electrodes, they become saturated – when this happens, the system automatically changes the polarity. The ions sticking to the electrodes fall off.

Step 3 Flush : Water is then flushed between the electrodes and the wasted ions are flushed to drain. The Polarity is reversed back and the Ion removal process (Step 1) starts again

Water Treatment Process

Figure 2: Schematic representation of the water treatment process

Working of CDI

1. Pre-treatment stage

Pre-treatment is a crucial component for water treatment. Proper pre-treatment is required to ensure smooth operation of the plant and lesser maintenance of the system.

AQUADION has the following pre-treatment steps (Stages 1-5 in Figure 2)

Raw water tank : Input from the Sump/Main lines enter the Raw water Tank

Low pressure pump : This is used to deliver suitable pressure to the sand filter and carbon filter and rest of the unit.

Pressure Sand Filter (PSF) :PSF is used to remove any turbidity in water. The PSF is filled with a mixture of gravel at the bottom, followed by fine sand and then a layer of Anthracite for good turbidity removal from water.

Activated Carbon Filter (ACF) :Water then passes through activated carbon present in a pressurized vessel. ACF is used to take out any organics in water and it also takes out any residual Ozone / chlorine present in water and restores taste.

Ultra Filter :A 0.001 micron, Anti- Bacterial Ultra-Filter is used to trap any residual carbon that may be coming out from the ACF. This filter also blocks any dirt / silt that might have accidently passed through the PSF and ACF.

2. Treatment Stage (Stage 6 in Figure 2)

Once water passes through the pre-treatment stages, it enters AQUADION for treatment. AQUADION systems are built modularly and delivered as a box. Each of these boxes will have a capacity to produce 4000 LPD of treated water. By building the system modularly we will ensure simpler maintenance and ease of installation.

Water coming out of AQUADION is directly sent to the output tank from where it will be discharged for consumption.

3. Post treatment stage (Stage 7 in Figure 2)

Post treatment ensures the electrodes in the cells are kept clean. This process is done automatically.

AQUADION can be programmed to run continuously for a period of 5 / 10 / 20 hours. After running for these durations, the system is programmed to rest for 1 / 2 / 4 hours respectively.

During the rest period, the system automatically sucks in a desired quantity of Maintenance solution (the duration of which can be set based on water condition). The system then cleans the electrodes with this solution. The entire cleaning operation takes about 5 minutes after which the system rests till the rest cycle is complete. This cleaning extends the life of the cells.

Web Interface and Remote Monitoring

The complete system works automatically and is web enabled, when connected through an internet, the system can also be accessed from anywhere for monitoring and maintenance purposes.

Web Interface

Users will be able to access the system through a tab, smartphone or computer using the web interface shown above. All functionalities of the machine including setup, status and performance parameters can be viewed using this screen.

AQUADION is also enabled for an IoT (Internet of Things) architecture which will allow users to operate and maintain the plant from anywhere once it is connected to the local area network.

All parameters such as flow, conductivity, pressure and any errors caused by the system can be seen using this interface and suitable action at site can be planned accordingly.

Work Site requirement

The total weight of the unit will be approximately 500 kgs (including all equipment shown). A suitable manual pallet lifter may be required to down load the equipment and take it to work place

AQUADION would need an enclosed space – preferably in a cooler place not next to any boilers or heat generating equipment

Total enclosed space dimension would be 6 feet x 6 feet by 8 feet (height).

Water to the outlet tank will be delivered at a maximum pressure of 1.4 Kg/cm2 (BAR). This would allow the water to climb up to a maximum height of 2 meters. The outlet tank must be suitably placed to ensure this discharge.

A single phase power connection is required with 4 direct 15/5 Amps Sockets. The connection has to be well grounded and if there are fluctuations then a Servo Stabilizer is required for the plant.
