DOMESTIC WASTEWATER TREATMENT – EFFECTIVE ENVIRONMENTAL PROTECTION SOLUTIONS FOR RESIDENTIAL AREAS, APARTMENTS AND BUSINESSES

What Is Domestic Wastewater Treatment?

Domestic wastewater is generated from daily human activities such as bathing, washing, cooking, dishwashing, toilet use and other household activities in residences, apartment buildings, hotels, schools, hospitals, office buildings and residential communities.

Domestic wastewater typically contains:

  • Organic pollutants (BOD, COD)

  • Suspended solids (TSS)

  • Oil and grease

  • Nitrogen and phosphorus compounds

  • Bacteria, viruses and pathogenic microorganisms

Without proper treatment, domestic wastewater can contaminate surface water and groundwater resources, negatively affecting public health and the environment.

VIET WATER JOINT STOCK COMPANY (VIET WATER JSC) specializes in consulting, designing, constructing, operating and maintaining domestic wastewater treatment systems for residential, commercial and industrial projects throughout Vietnam.

Characteristics of Domestic Wastewater

Domestic wastewater is characterized by relatively high biodegradable organic content and significant concentrations of pathogenic microorganisms.

Typical Wastewater Parameters

Parameter Typical Range
BOD5 150 – 400 mg/L
COD 250 – 800 mg/L
TSS 100 – 350 mg/L
Total Nitrogen 20 – 80 mg/L
Total Phosphorus 4 – 15 mg/L
Coliform Very High

Proper treatment is required to ensure compliance with environmental discharge regulations.

Why Is Domestic Wastewater Treatment Important?

Regulatory Compliance

Residential complexes, apartment buildings, hotels, factories and commercial facilities are required to install wastewater treatment systems in accordance with environmental regulations.

Protection of Water Resources

Wastewater treatment helps prevent pollution of rivers, lakes, canals and groundwater resources.

Public Health Protection

Treatment systems remove harmful bacteria, viruses and disease-causing pathogens before discharge.

Corporate Social Responsibility

Environmental compliance enhances corporate reputation and demonstrates commitment to sustainable development.

Sustainable Water Management

Wastewater treatment contributes to water conservation and supports green development initiatives.

Domestic Wastewater Treatment Process

Depending on project scale and effluent quality requirements, Viet Water designs customized treatment systems using appropriate technologies.

Wastewater Collection and Screening

Wastewater is collected through:

  • Bar screens

  • Basket screens

  • Collection pits

These units remove large debris and protect downstream equipment.

Equalization Tank

The equalization tank serves to:

  • Stabilize wastewater flow

  • Balance pollutant concentrations

  • Prevent biological shock loading

Mixers or aeration systems are commonly installed to prevent sedimentation.

Biological Treatment

Biological treatment is the core process of domestic wastewater treatment systems.

Aerotank Process

Utilizes aerobic microorganisms to degrade organic pollutants.

MBBR Technology

Moving Bed Biofilm Reactor technology uses suspended media carriers to increase biomass concentration and treatment efficiency.

SBR Technology

Sequencing Batch Reactor integrates multiple treatment stages within a single tank, reducing construction area.

MBR Technology

Membrane Bioreactor combines biological treatment with membrane filtration to achieve superior effluent quality.

AAO Technology

Anaerobic-Anoxic-Oxic technology effectively removes BOD, nitrogen and phosphorus.

Secondary Clarification

Separates biological sludge from treated wastewater.

Disinfection

Treated water is disinfected using:

  • Chlorination

  • Ultraviolet (UV) systems

  • Ozone systems

This process eliminates harmful microorganisms before discharge.

Discharge or Reuse

After treatment, water may be:

  • Discharged in compliance with environmental regulations

  • Used for landscape irrigation

  • Road washing

  • Cooling water applications

  • Other non-potable reuse purposes
