  • How many wastewater treatment plants are there in Thailand?
  • In 2017, Thailand had 97 active central municipal wastewater treatment plants (WWTPs), covering 55 of the country's 77 provinces (Pollution Control Department 2017b). However, only a small number of treatment systems have installed chlorine disinfection systems beyond secondary treatment, which are suitable for reuse purposes.
  • Does TCB meet the standard of water quality in Thailand?
  • DO, BOD and TCB did not meet the standard of water quality of Thailand ( Haapala, 2002, Simachaya et al., 2000 ).
  • Is wastewater reclamation a solution to Thailand's water scarcity problem?
  • The Thai government, industries, the private sector and academic institutions are increasingly paying attention to wastewater reclamation from WWTPs as a solution to the country's water scarcity problem. However, most wastewater treatment facilities here have not been upgraded or monitored for effective reuse of water.
  • Are surfactants harmful to the environment in Thailand?
  • The surfactant consumption has rapidly increased in Thailand, the household and laundry sectors being the major markets ( Colin, 1996 ). Hence surfactants may be considered as major contaminants in the environment of Thailand, especially in surface waters.
