With advanced wastewater treatment technologies, WINTEC effectively purifies various industrial wastewater streams
and establishes sustainable production environments.
WASTE WATER TREATMENT SYSTEM
(Wastewater Treatment System)
Environment division
Equipment Overview

Wastewater treatment systems refer to comprehensive facility systems that treat various industrial wastewater through sequential physical,
chemical, and biological processes, reducing pollutant concentrations below legal discharge
standards for safe discharge into public water bodies or reuse.
Rather than a single treatment unit, wastewater treatment systems are integrated solutions that combine multi-stage processes — including pretreatment, primary treatment, advanced treatment, and sludge treatment — optimized according to wastewater characteristics such as BOD, COD, SS, heavy metals, pH, and specific water pollutants.
WINTEC provides comprehensive EPC turnkey solutions, covering the entire process from wastewater characterization
and process design to equipment procurement, construction, commissioning, and permitting support.
Treatment Process Flow
Each treatment process is configured as a standalone or integrated system depending on wastewater characteristics and discharge requirements.
Wastewater Inflow
Pretreatment
Physicochemical Treatment
Biological Treatment
Advanced Treatment
Discharge / Reuse
Sludge Treatment
Thickening → Dewatering → Final Disposal (Incineration → Landfill → Resource Recovery)
Target Pollutants
WINTEC provides customized wastewater treatment solutions tailored
to the characteristics of various industrial wastewater streams.
Organic Matter (BOD & COD)
Suspended Solids (SS)
Nitrogen & Phosphorus (T-N & T-P)
Heavy Metals (Cr, Pb, Cd, Cu, Zn & Ni)
Fluoride (F⁻)
Cyanide (CN⁻)
High-Concentration Ammonia (NH₃-N)
Volatile Organic Compounds (VOCs)
Color & Refractory Organic Compounds
Comparison of Sludge Dewatering Equipment Types
| Types of Dewatering Equipment | Operating Principle | Applicable Capacity | Dewatered Cake Moisture Content |
|---|---|---|---|
| Belt Press | Gravity & Pressure Dewatering | Medium to Large Scale | 75 ~ 82% |
| Filter Press | High-Pressure Compression | Small to Medium Scale | 60 ~ 75% |
| Centrifuge Dewatering Machine | Centrifugal Force Separation | Medium to Large Scale | 78 ~ 85% |
| Screw Press | Screw Compression | Small to Medium Scale | 75 ~ 83% |
Permitting & Regulatory Compliance
Preparation and Submission of Wastewater Discharge Facility Permit & Notification Documents
Preparation of Pollution Control Facility Drawings, Process Flow Diagrams, and Treatment Capacity Calculations
Calculation of Water Pollutant Emissions and Compliance Review with Discharge Standards
Startup Notification
TMS (Water Quality Tele-Monitoring System) Applicability Review and System Integration
(Mandatory Installation for Wastewater Discharge of 200 m³/day or More)
Verification of Effluent Quality Compliance and Support for Periodic Monitoring
In accordance with Article 33 of the Water Environment Conservation Act (Permit & Notification for Wastewater Discharge Facilities),
installation permits or notifications must be obtained from the relevant provincial or municipal authorities. Facilities discharging specific hazardous water pollutants (Cr, Pb, Cd, Cu, F⁻, CN⁻, phenol, etc.)
above regulated levels are subject to mandatory installation permits.
WINTEC provides comprehensive one-stop support throughout the entire process.
