The proper depuration plant is chosen by considering:

• the chemical characteristics of the waste waters
  
• the untied substances
  
• the treating waste water volumes
  
• the possible waters recycle after the dapuration
  
• other

:: galvanic sector
:: industrial washing
:: selective resins for heavy metals
