Introduction to Groundwater and Well Water Treatment Services

Groundwater and well water remain important water sources for factories, industrial parks, farms, commercial facilities and residential communities. However, groundwater quality often varies depending on geological conditions and may contain iron (Fe), manganese (Mn), ammonium (NH₄⁺), hardness, salinity, heavy metals and other dissolved minerals that can negatively affect production processes and human health.

VIET WATER JOINT STOCK COMPANY (VIET WATER JSC) provides professional consulting, design, construction, operation and technology transfer services for groundwater and well water treatment systems. Our solutions are optimized for investment cost, operational efficiency and long-term reliability.

Why Is Groundwater Treatment Necessary?

Although groundwater is generally less contaminated by organic pollutants than surface water, it is heavily influenced by local geological formations.

Common groundwater issues include:

• Iron contamination (Fe)
• Manganese contamination (Mn)
• High ammonium concentration
• Water hardness
• Acidic groundwater
• Salinity intrusion
• Hydrogen sulfide (H₂S) odor
• High dissolved mineral content
• Heavy metals and trace contaminants

Without proper treatment, these contaminants may cause:

• Corrosion of industrial equipment
• Pipe scaling and blockage
• Product quality deterioration
• Health risks
• Failure to meet drinking water and industrial water standards

Characteristics of Groundwater and Well Water

Classification by Aquifer Depth

Shallow Groundwater

• Typically located 2–4 meters below ground surface
• Easily affected by surface contamination
• Water quality is often unstable

Intermediate Groundwater

• Better water quality
• Less vulnerable to environmental impacts
• Commonly used for domestic water supply

Deep Groundwater

• Located between impermeable geological layers
• Stable flow rate and water quality
• Widely used in industrial applications

Typical Components Found in Groundwater

Groundwater may contain:

• Calcium (Ca²⁺)
• Magnesium (Mg²⁺)
• Sodium (Na⁺)
• Ammonium (NH₄⁺)
• Iron (Fe)
• Manganese (Mn)
• Chloride (Cl⁻)
• Sulfate (SO₄²⁻)
• Dissolved CO₂
• Hydrogen Sulfide (H₂S)
• Methane (CH₄)

In some areas, groundwater may also contain:

• Arsenic (As)
• Lead (Pb)
• Mercury (Hg)
• Nitrate (NO₃⁻)
• Volatile Organic Compounds (VOCs)

Groundwater Quality Assessment

Based on groundwater analyses, parameters such as:

• Arsenic (As)
• Barium (Ba)
• Mercury (Hg)
• Lead (Pb)
• Cadmium (Cd)
• Nitrate (NO₃⁻)
• Benzene
• Chloroform
• Volatile Organic Compounds (VOCs)

should be carefully evaluated before selecting an appropriate treatment technology.

Since every water source has unique characteristics, treatment solutions must be customized according to actual laboratory results rather than applying a one-size-fits-all approach.

Common Needs for Groundwater Treatment

Businesses often seek Viet Water’s services when experiencing:

• Unstable raw water quality
• Yellowish water or turbidity
• Iron and manganese contamination
• High water hardness
• Poor performance of existing treatment systems
• Fluctuating treated water quality
• New clean water system requirements for factories and industrial facilities

Groundwater and Well Water Treatment Technologies

Depending on water quality and intended use, Viet Water selects the most suitable treatment technology.

Aeration for Iron and Manganese Removal

One of the most effective methods for treating groundwater containing Fe and Mn.

Typical Treatment Units

• Cascade aerators
• Aeration towers
• Oxidation tanks

Advantages:

• Low investment cost
• High efficiency
• Easy operation

Chemical Oxidation

Using strong oxidizing agents such as:

• Chlorine (Cl₂)
• Ozone (O₃)
• Potassium Permanganate (KMnO₄)

to convert dissolved iron and manganese into removable precipitates.

Lime Softening and Iron Removal

Suitable for groundwater with:

• High hardness
• Elevated iron content

Often combined with water softening processes.

Microfiltration (MF)

Removes:

• Suspended solids
• Fine particles
• Microorganisms

Ion Exchange Technology

Applicable for:

• Water softening
• Nitrate removal
• Ammonium removal
• Heavy metal removal

Reverse Osmosis (RO)

RO is an advanced treatment technology capable of removing:

• Dissolved salts
• Heavy metals
• Nitrates
• Bacteria
• Viruses

with treatment efficiency reaching 95–99%.
