Ion-Exchange System

 These two systems used ion-exchange method to adsorb heavy metal ions from the waste streams of electroplating production lines, the waste streams contained copper ions (Cu2+), nickel ions (Ni2+) and dichromate ions  (Cr2O7-) at concentration of about 10-20 ppm :

Chlorinator

These two systems are chlorinators which use DC current to electrolysis salt water (NaClaq) to form bleach or called sodium hypochloride (NaOCl) (a strong oxidizing agent) as a disinfectant :

Sequencing Batch Reaction System (SBR)

This system use microorganisms to treat the oily wastewater from the grease traps. The wastewater passes through a "Dissolved Air Flotation" (DAF) System first (not shown here) to remove large amount of floating oil and then stored in the feed tank of this SBR system.

Ultra Filtration

Ultra filtration (UF) is world wide trend used in water and wastewater treatment in recent years, the advantages are obvious:

 

 This system is a pilot scale UF system set up in a municipal wastewater treatment plant
