Reduce costs and production time for your concentration and purification needs using FMX

FMX has been used not only for treating high strength wastewater such as polymer production waste, but also to concentrate colloidal particles as a dewatering process. Such applications are possible thanks to its unique anti-fouling mechanism designed to handle high feed solids, up to 40% for some applications.

CASE STUDY

Methylcellulose Wastewater Treatment

Conventional and competing membrane technologies were tested for methylcellulose wastewater treatment, but none could cost effectively separate the non-biodegradable substances from the waste. By applying the FMX, Samsung Fine Chemicals in South Korea is able to reduce the volume of wastewater from 100 tons per day to 35 tons per day, drastically reducing wastewater treatment costs.

Methylcellulose is a chemical compound produced by larger chemical companies, which has various uses such as a thickener, lubricant, or emulsifier in multiple applications. During the equipment cleaning process, significant amounts of methylcellulose are washed off into the wastewater. This wastewater is very difficult to treat using biological treatment due to the significant amount of non-biodegradable substances present. Thus, activated carbon is often used first to treat the wastewater before it is sent to conventional biological treatment. Conventional and competing membrane technologies were tested for methylcellulose wastewater treatment, but none could cost effectively separate the non-biodegradable substances from the waste.

By applying the FMX, Samsung Fine Chemicals in South Korea is able to reduce the volume of wastewater from 100 tons per day to 35 tons per day, drastically reducing wastewater treatment costs. Additionally the FMX permeate contains readily biodegradable organic carbon such as methanol, which can be given or sold to local municipal wastewater treatment plants to function as a carbon source. The remaining concentrate can be further treated in a treatment process including powder activated carbon and biological nutrient removal.

The FMX was so successful at reducing the volume and cost associated with methylcellulose wastewater treatment, Samsung has ordered a total of 8 units over the past eight years.

COLLOIDAL PARTICLE CONCENTRATION

The typical production process uses conventional membrane systems or evaporators to concentrate the colloidal particles, but low production capacity, high operation and maintenance costs, and decreased ability to concentrate the particles caused a large U.S. chemical manufacturer to look for a new solution. The FMX was able to concentrate an initial colloidal particle concentration of 6%, to over 42% in the final product.

Increase it using FMX.

Many large chemical companies across the globe are involved in the production of colloidal particles to be used as a raw material in other production processes, such as for electronics. The typical production process uses conventional membrane systems or evaporators to concentrate the colloidal particles, but low production capacity, high operation and maintenance costs, and decreased ability to concentrate the particles caused a large U.S. chemical manufacturer to look for a new solution.

Parameter Units Batch 1 Batch 2
Average Flux LMH (GFD) 120 (71) 121 (71)
Initial concentration wt% 6% 6%
Final concentration wt% 44.7% 42.4%

Pilot test results showed the FMX could not only achieve higher final product concentrations, but was also able to reduce fouling with the unique vortex system. The FMX was able to concentrate an initial colloidal particle concentration of 6%, to over 42% in the final product. During concentration the FMX can maintain a substantially higher flux when compared to the previous conventional membrane system, resulting in shorter processing times and lower operation and maintenance costs.
