Prestigious Wastewater Treatment Services

What is wastewater treatment service?

Wastewater treatment is the process of removing contaminants in wastewater before it is discharged into the environment. Wastewater is used water that contains human or industrial waste. These wastes can be harmful to human health and the environment if left untreated.
Common types of wastewater:
  • Domestic wastewater: from toilet, bathroom, sink, kitchen. Contains organic matter, bacteria, grease, soap.
  • Industrial wastewater: from factories, enterprises. Contains heavy metals, acids, alkalis, industrial grease.
  • Medical wastewater: from hospitals, clinics. Contains bacteria, viruses, medicines.

Typical wastewater treatment steps:

  1. Pretreatment: Clean large solids by hand, barricade or filter mesh.
  2. Rainwater treatment: Separate rainwater to reduce the waste water load for the treatment system.
  3. Gravity Treatment: Clear the residue by keeping the water in the tank for 1-2 days. Solids heavier than water will settle to the bottom.
  4. Bioremediation: Using bacteria or enzymes that break down organic matter.
  5. Chemical treatment: Add biocide chemicals, precipitate heavy metal ions.
  6. Physical treatment: Using activated carbon filter adsorption pollution, ultraviolet light sterilization.
  7. Final treatment: Discharge treated water to rivers, lakes or reuse.

Current advanced wastewater treatment technology

  • Membrane technology: Uses reverse osmosis membranes that remove any impurities. Allows clean water reuse.
  • Aerobic – anaerobic biological treatment technology: Application of aerobic and anaerobic active bacteria to decompose organic matter.
  • Advanced Oxidation Technology: Uses oxygen, ozone, chlorine to powerfully oxidize and kill bacteria.
  • Electrostatic membrane treatment technology: Using static current to create a membrane to adsorb metal ions.
  • Closed-cycle treatment technology: Optimize the water treatment process into a closed cycle, reducing waste.

Benefits of wastewater treatment services

  • Protect public health: Eliminate pathogens, prevent disease from spreading through water sources.
  • Environmental protection: Reduce water, soil and air pollution. Preserve natural ecosystems.
  • Save and reuse water: Post-treatment water can irrigate plants, wash streets, replenish air conditioning pools.
  • Reduce the cost of pollution treatment: Treatment at the source reduces the cost of treating pollution at its source is very expensive.
  • Compliance with legal regulations: Environmental protection laws require wastewater treatment before discharge into the environment.
Wastewater treatment standards
  • Vietnam Standard: QCVN 14: 2008 / BTNMT – National technical regulation on domestic wastewater.
  • American Standards: Effluent Guidelines of the U.S. Environmental Protection Agency.
  • EU Standard: Council Directive 91 / 271 / EEC on municipal wastewater treatment.
  • WHO Standard: Guidelines for medical wastewater treatment by the World Health Organization.
Steps for selecting wastewater treatment services
  • Identify the source and amount of wastewater to be treated
  • Selection of treatment technology suitable for wastewater type
  • Assessment of investment, operation and maintenance costs of the system
  • Selection of reputable contractors, project implementation experience
  • Test the processing system works stably, up to standard
  • Negotiation of service contract, warranty, long-term maintenance
