River Water Treatment System for Safe Drinking

 
 

Situation

A remote agricultural community suffered from severe water shortages when their ineffective media filter deteriorated and their conventional membrane system broke down in a matter of weeks due to extremely poor feedwater quality.

 
 

Site

River next to palm oil plantation in East Malaysia.

 
 

Feedwater Characteristics

Turbidity of 100-300 NTU depending on seasonality. Feedwater has high Total Suspended Solids (“TSS”) and organic content.

 
 

Treatment Objective

Provide 0.2 MLD of product water with turbidity of <5 NTU.

 
 

Conclusion

Objective surpassed with product water turbidity <0.1 NTU. River water treatment system validated by government department to meet National Drinking Water Quality Standard.

Mining Wastewater Treatment for Safe Discharge

  mining wastewater treatment
 

Situation

A large mining operation sought an effective treatment system to reduce the high turbidity and arsenic levels of the wastewater. Given its location, it had to be effective in an open area and easily maintainable.

 
 

Site

Gold mine in Malaysia.

 
 

Feedwater Characteristics

Turbidity of 80-350 NTU. Feedwater has high arsenic content of >1,000 ppb.

 
 

Treatment Objective

Provide 3.6 MLD of product water for safe discharge with turbidity reduced to <5 NTU and arsenic <10 ppb.

 
 

Conclusion

Objective surpassed with product water turbidity <0.5 NTU, arsenic <6 ppb and reduced usage of hydrogen peroxideand ferric chloride.

Groundwater Treatment for Commercial Aquaculture Farm

 
 

Situation

Groundwater from an arowanna fish farm had extremely high iron and manganese levels that affected the survival of the highly prized fish and fouled the pipes.

 
 

Site

Commercial aquaculture farm.

 
 

Feedwater Characteristics

Feedwater is red with high iron content of >30 ppm and turbidity >130 NTU.

 
 

Treatment Objective

35,000 litres of water per day with significantly lowered iron and manganese content and turbidity <5 NTU.

 
 

Conclusion

Our groundwater treatment system was chosen due to its efficacy and cost. Product water had lowered iron and manganese content with reduced turbidity of <5 NTU.

Cooling Water Treatment to generate cost savings

 
 

Situation

An international oil and gas firm had issues with its chiller systems due to high turbidity and iron content, resulting in lower heat transfer efficiency, more frequent chemical dosing and maintenance.

 
 

Site

Chillers of an international oil and gas firm’s training centre.

 
 

Feedwater Characteristics

Difficult to treat with colloidal particles, with turbidity of 45 NTU and high iron content of 12 ppm.

 
 

Treatment Objective

Reduce chilled water turbidity to <20 NTU and iron to <1 ppm.

 
 

Conclusion

Objective surpassed with product water turbidity at <5 NTU and iron at <1 ppm.

 
 

Ozone Treatment for Bottled Water Production

 
 

Situation

A bottled water manufacturer had problems with its feed water. It had high levels of iron and manganese that affected taste and fouled pipes. Harmful microbial growth was also present.

 
 

Site

One of the largest bottled water manufacturing facilities in Malaysia.

 
 

Feedwater Characteristics

High iron and manganese content along with microorganism growth.

 
 

Treatment Objective

Reduce the iron and manganese levels as well as disinfect using ozone.

 
 

Conclusion

Our ozone systems helped increase the water quality to bottled drinking water quality standards.
