TREATING WASTEWATER

FLEXI has modular wastewater treatment systems that can be prefabricated and combined according to clients’ different types and volumes of effluent to be treated and discharged.

Customised Industrial Wastewater Treatment Systems

Our High Concentration Cyanide Decomposition System can treat wastewater containing cyanide with concentrations of up to hundred thousands PPM and achieve 99.99% removal rate. It does not use liquid bleach and is therefore environmentally friendly.

Features and Benefits:
  • System’s plug-and-use feature allows for immediate use of system upon connection of electricity mains on site
  • Modularity in design allows for easy transportation
  • Modules can be stacked to reduce site area required for installation of system
High Concentration Cyanide Decomposition System

Our High Concentration Cyanide Decomposition System can treat wastewater containing cyanide with concentrations of up to hundred thousands PPM and achieve 99.99% removal rate. It does not use liquid bleach and is therefore environmentally friendly.

Features and Benefits:
  • Achieves up to 99.99% removal of cyanide of concentrations up to hundred thousands PPM
  • Lower operations cost compared to conventional method
  • By-product (NH3, Ammonia) can be reused to produce nitrogen fertiliser
  • Simple, automatic process with short processing time

ITEMS SPECIFICATIONS
Treatment Capacity 500L per Batch
Processing Time Batch processing time subjected to concentration of incoming cyanide
Chemical Injection Method Electrical Diaphragm Metering Pump
Electrical  Requirement 220V, 5kWh
System Installation Required Area 4m x 4m x 3m(H)
Chromic Acid Purification System

Our Chromic Acid Purification System can purify aged chromic acid and achieve 90% removal rate by using a unique type of resin in the ion exchange process. The purified chromic acid can be reused again for production processes if required. Note however that System is not suitable for chromic acid coarsening process.

Features and Benefits:
  • Achieves up to 90% removal of iron and copper ion
  • Special anti-oxidative resin used in System has relatively longer life
  • Ion exchange process in System is highly corrosive resistant
  • Purified chromic acid can be reused
  • Lower operations cost compared to conventional method
  • Simple, automatic process with short processing time
