01
Wastewater Inflow & Equalization
Fluctuations in flow rate and water quality over time are smoothed to stabilize downstream processes.
ENVIRONMENTAL SOLUTION
Water Pollution Control Facility
Building a stable treatment process by analyzing industrial wastewater composition and discharge requirements.INDUSTRIAL WATER TREATMENT
Connecting influent composition to discharge standards —
a site-tailored water treatment process.
The type and concentration of pollutants in industrial wastewater vary greatly depending on the production process and raw materials used. Stable discharge water quality requires accurately understanding influent quality, daily treatment volume, and load fluctuations.
Changjo Eng combines the necessary unit processes — physicochemical treatment, sedimentation, filtration — while also accounting for chemical usage, sludge generation, and maintenance access when configuring the treatment system.
PROCESS FLOW
Treatment Process
Pre- and post-treatment stages are combined to fit each site's conditions.02
Chemical Reaction
pH adjustment and coagulation/reaction conditions are formed to match pollutant characteristics.
03
Solid-Liquid Separation & Filtration
Formed flocs and suspended solids are separated and filtered to the required level.
04
Water Quality Check & Discharge
Treated water condition is verified and safely discharged in compliance with standards.
PROCESS ENGINEERING
Treatment performance and operating efficiency are designed together.
For a water treatment facility, the balance of the whole process matters more than any single unit. We size capacity and residence time and configure automatic control so every stage — from flow adjustment through chemical reaction to solid-liquid separation and filtration — connects stably.
- Influent AnalysisIdentifying water quality parameters, concentration, and daily/hourly fluctuation conditions
- Process CombinationStaged configuration of unit processes matched to the treatment target
- Chemical OptimizationControl that reduces overdosing and raises reaction efficiency
- Sludge ManagementOperating plan that accounts for generation volume, dewatering, and removal
DESIGN POINT
Standards for consistent discharge water quality
Load Fluctuation Response
Buffer capacity is secured so downstream processes keep running stably despite changes in flow rate and concentration.
Water Quality Target Management
Designed so reaction conditions and filtration stages can be adjusted to match treatment targets.
Operating Convenience
Controlled so chemical dosing, pump operation, and water-level management run efficiently.
