Yimei Integrated Wastewater Treatment Equipment has once again completed manufacturing and export shipment and is about to be delivered to the Vietnam market. This marks the third shipment of a Packaged Wastewater Treatment Plant to Vietnam this year, fully demonstrating overseas customers’ high recognition of Yimei’s environmental equipment manufacturing capabilities, engineering expertise, and wastewater treatment solutions.

With the continuous advancement of industrialization in Southeast Asia and increasingly stringent environmental standards, the demand for stable and energy-efficient Wastewater Treatment Equipment is growing across various industries. Leveraging years of experience in Wastewater Treatment Engineering, Yimei provides customized Integrated Wastewater Treatment Solutions based on diverse customers’ water quality characteristics and treatment requirements, continuously contributing to sustainable environmental development in Southeast Asia.

Project Background
This project focuses on the treatment of latex wastewater with a capacity of 120 m³ per day. Listed below are the key water quality indicators of the latex wastewater.

High Organic Matter Content
Suspended Solids
Wide pH Fluctuation
High COD (Chemical Oxygen Demand) and BOD (Biochemical Oxygen Demand)
High Ammonia Nitrogen Content
High Coloration
Trace Toxic Substances

High Temperature
Abundant Foam

Challenges in Treatment:

Colloidal Stability: Colloidal substances in latex wastewater are highly stable and difficult to remove through conventional physical methods.

Organic Matter Degradation: Although organic matter is biodegradable, some synthetic latex components may be difficult to degrade.

Foaming Issues: The surfactants in the wastewater can cause excessive foaming during treatment, affecting the normal operation of treatment equipment.

Customized Wastewater Treatment Solution
Yimei relies on customer-provided data on raw water quality, flow volume, and discharge requirements, and utilizes core technologies along with an intelligent PLC control system to achieve stable treatment and compliant discharge of latex wastewater. 
Based on the characteristics of latex wastewater, the main treatment process is designed as follows: 
Equalization of water quality and flow → Coagulation and flocculation → Solid-liquid separation → Biological treatment → Sedimentation → Sludge treatment → Compliant discharge 

Core Equipment Configuration 
Water Quality and Flow Rate Equalization 
Regulates influent water quality and flow rate to minimize the impact of production fluctuations on system operation. 

Coagulation and Flocculation System 
Our automated system adds precise dosages of chemicals to form flocs from colloidal particles and suspended solids in latex wastewater, enhancing solid-liquid separation efficiency. 

Biological Treatment System 
Utilizes suspended packing media as a microbial attachment surface, improving biological treatment capacity—particularly suitable for industrial wastewater with significant water quality variations. 

Sedimentation and Separation System 
Effectively separates sludge generated during prior biological processes, ensuring high-quality effluent downstream. 

Sludge Treatment System 
Concentrates and dries excess sludge produced, reducing overall sludge disposal costs.

Based on wastewater experience data and information provided by the client, the influent water quality and effluent standards are designed as follows:

Why choose to collaborate with Yimei?

As a Chinese manufacturer, Yimei has stood out in the industrial wastewater treatment industry. Our customers highly appreciate and trust our equipment performance, mature wastewater treatment technology, and strong comprehensive corporate strength. Our extensive project experience enables us to provide stable, reliable, and long-term compliant wastewater treatment solutions for global manufacturing enterprises. 

Professional equipment and core technology advantages

Small floor area, no complex civil construction

We customize integrated modularization for our clients, integrating all treatment units, including water quality balancing, coagulation and flocculation, biological treatment, sedimentation and sludge treatment, into a complete set of equipment. This saves floor space, eliminates the need for complex civil construction, and enables flexible installation and rapid commissioning, making it suitable for factory renovations and overseas project deployments. 

Intelligent fully automatic operation

This equipment is equipped with a standard intelligent PLC control system. The entire wastewater treatment process can be operated automatically and real-time operation monitoring can be carried out. It effectively adapts to the fluctuations in the quality and volume of latex wastewater. 

Stable processing performance

The equipment incorporates optimized biological filler technology, effectively removing suspended solids, colloidal particles, and organic pollutants specific to latex wastewater. This addresses the common problem of unstable processing results of traditional sewage treatment equipment. 

Low operating and maintenance costs

Our designed efficient sludge treatment system can minimize the amount of sludge generated and reduce the cost of sludge treatment. Its integrated structure reduces the number of vulnerable components, which lowers the frequency of daily maintenance and the overall operational investment. 

Our extensive project experience across the globe is one of the advantages that enables us to offer precise wastewater treatment solutions. Choosing products Yimei made in China is supported by a reliable track record of quality.
