Surface Water and River Water Treatment Solutions for Industrial and Domestic Water Supply

Surface water from rivers, lakes, canals, and reservoirs is one of the most important water sources for domestic consumption, industrial production, and agricultural activities. However, the quality of surface water is often affected by seasonal changes, industrial discharge, domestic wastewater, and environmental conditions. Therefore, investing in an efficient surface water treatment system is essential to ensure a stable and reliable water supply.

VIET WATER JOINT STOCK COMPANY (VIET WATER JSC) specializes in consulting, designing, constructing, operating, and transferring technologies for surface water and river water treatment systems. Our solutions are optimized to provide high treatment efficiency, reasonable investment costs, and stable water quality that meets customer requirements.

Characteristics of River Water Requiring Treatment

River water quality can vary significantly depending on weather conditions, seasonal fluctuations, and surrounding environmental impacts.

High Suspended Solids Content

River water often contains:

• Sand and silt

• Suspended organic matter

• Algae and microorganisms

These contaminants increase turbidity and affect water quality.

Variable Organic Content

Parameters such as:

• BOD (Biochemical Oxygen Demand)

• COD (Chemical Oxygen Demand)

• TOC (Total Organic Carbon) may fluctuate due to industrial and domestic wastewater discharges.

Microbiological Contamination

River water may contain:

• Bacteria

• Viruses

• Coliforms

• E. coli which pose potential health risks.

Seasonal Variations

During the rainy season:

• Turbidity increases significantly

• Sediment concentration rises

During the dry season:

• Pollutant concentrations increase

• Saltwater intrusion may occur in coastal regions

Basic River Water Treatment Process

Depending on raw water quality and treated water requirements, Viet Water applies the most suitable treatment technologies.

Pretreatment – Removal of Coarse Impurities

The first stage removes:

• Debris

• Leaves

• Branches

• Floating materials

using:

• Bar screens

• Coarse strainers

• Intake structures

Coagulation and Flocculation

Coagulants are added to destabilize suspended particles and form larger flocs for easier removal.

Common chemicals include:

• PAC (Polyaluminum Chloride)

• Polymer

• Alum

Sedimentation and Filtration

Flocs settle in sedimentation tanks and are subsequently removed.

The water then passes through:

• Sand filters

• Multimedia filters

• Activated carbon filters

to remove fine particles and residual organic compounds.

Disinfection

Filtered water is disinfected using:

• Chlorine

• Ultraviolet (UV)

• Ozone

to eliminate pathogenic microorganisms.

Fine Filtration or Membrane Technology

For higher-quality water requirements, advanced treatment systems may include:

• Ultrafiltration (UF)

• Nanofiltration (NF)

• Reverse Osmosis (RO) to further enhance water quality.

Applications of Surface Water Treatment Systems

Surface water treatment systems are widely applied in various sectors.

Domestic Water Supply

Suitable for:

• Residential areas

• Apartment complexes

• Urban developments

• Schools

• Hospitals

Industrial and Manufacturing Facilities

Used for:

• Process water

• Cooling water

• Boiler feed water

• RO feed water systems

Agricultural Applications

Including:

• Irrigation systems

• Livestock farms

• Aquaculture facilities
