As a Water Purification expert, Guangdong Xinjieyuan is committed to providing comprehensive pure water solutions!
As you know, In many regions around the world that lack surface freshwater resources, it is necessary to obtain water resources through deep digging of wells. And these deep-well -groundwater have the characteristics of high salt, high mineral content, and water hardness, human being can not use & drink such water directly.

So, how to purify such water into freshwater (or drinking water)is a very important for humans.

Xinjieyan have rich experience in this area, Today, let's talk about how to purify and desalt the groundwater(brackish) .

What solutions does XJY use for groundwater(brackish) water purification?

1.Overview of groundwater(brackish) water quality:

high salt, hardness, high mineral content, Abnormal pH value

2.What is the purpose of a groundwater(brackish) water purification system?

domestic water & drinkable water

3.What are the steps in the groundwater(brackish) water purification machine process?

A. With Pump water through a pump, pass through a simple filter, and enter the settling pad of the original water tank.

B. Pre-filtration: Quartz Sands & Activated Carbon filter

C. Reduce hardness: Resin exchange by water softener (removal Ca. & Mg. Ions)

D. Descaling system:If the mineral content in the ground water is too high, we need further descaling to protect the subsequent filtration module.

E. Security Filter: low cost & high efficiency filter to protect the RO membrane.

F. ro system: Using the specialized membrane to remove salt and other ions.

G. Ph regulator : acid-base balance, confirm PH 6.5~8

H. UV sterilization or O3 sterilization to keep the water in safety for drinkable.

4.The core components of groundwater(brackish) water purification plant:

Xinjieyuan choose anti pollution and high Desalination rate membrane.

What are the practical challenges in water purification equipment?

In short of fresh water area, such as in the vast regions of Africa, central South America, and central of Asia, using groundwater has become the important option, but about the technology still face too much challenges:

Energy supply: Many regions lack stable electricity and require the adoption of low-energy technologies. (For example, using a combination of solar energy and diesel engines can reduce emissions and ensure electrical safety)

Cost control: RO membrane is high cost for users.

Maintenance management: For bad water quality, it will short the lifespan of the equipment.

In response to the above challenges, we recommend that users try to use larger sized devices to handle these high salinity water, which can improve water efficiency and benefit more people.
