Environmental Plant
Water Treatment System
SYSTEM Configuration
Depending on the required water quality, the system can be configured with various equipment. For general industrial water, the configuration includes a Make-up System, while a Polishing System is added when water quality higher than purified water is required.

Pre-treatment equipment
MMF(Multi Media Filter)
Function
Removes suspended solids from raw water by passing it through porous media layers such as sand and anthracite.
Features
- Effective removal of turbidity and suspended solids (SS) from raw water
- Easily applicable as pre-treatment for all downstream processes
ACF(Activated Carbon Filter)
Function
Removes suspended solids, taste and odor, and oily substances from raw water by utilizing the adsorption capacity of activated carbon.
Features
- Various types of activated carbon are available depending on form and raw material
- Removal of turbidity and suspended solids (SS) from raw water
- Effective removal of taste and odor
- Capable of removing organic substances and gases
DAF(Dissolved Air Flotation)
Function
Suspended solids in raw water are removed by flotation, in which air bubbles attach to the particles and carry them to the water surface.
Features
- Removal of turbidity and suspended solids (SS) from raw water
- Capable of removing algae
- Capable of removing oil and grease
MF(Micro Filter)
Function
Removes fine suspended solids in the range of 0.1 μm to 10 μm by filtering raw water through a precisely structured screen surface with fine, uniform pores.
Features
- Available in pressurized and cartridge types
- Used for water treatment, wastewater treatment, water reuse systems, and pre-treatment for seawater desalination
UF(Ultra Filter)
Function
With a pore size intermediate between MF and RO, this system filters and removes substances in the range of approximately 0.001 to 0.01 μm from raw water.
Features
- Backwashable, providing a long service life
- Used as pre-treatment and post-treatment for ultra-pure water (UPW) production systems
- Applied as pre-treatment for reverse osmosis (RO) systems and in water reuse facilities
- Available in pressurized and submerged configurations
