Product introduction
Double-Effect Evaporator System
20 years of industry expertise, providing advanced and efficient evaporation solutions to recycle wastewater and significantly reduce energy costs.
Are You Facing These Wastewater Treatment Challenges?
We understand the challenges you face in wastewater treatment and provide targeted solutions.
High Operating Costs
Traditional methods have high energy consumption and chemical costs, increasing operational pressure.
Strict Environmental Policies
Rising standards lead to risks of heavy fines and production suspension for non-compliance.
Unstable Equipment
Low automation and frequent breakdowns impact production schedules and stability.
Inadequate Treatment
Complex wastewater components make it difficult to achieve stable compliance and low reuse rates.

Comprehensive After-Sales Service
Our professional team provides installation, commissioning, training, and lifelong technical support for your peace of mind.
Complete Pre-Evaporation Process Flow Design
We provide a comprehensive solution from pretreatment to final crystallization, ensuring high efficiency, energy savings, and stable system performance.
Pretreatment
Removes suspended solids, large impurities, and harmful components from the raw liquid through physical and chemical methods, adjusting the pH to provide a stable and clean feed for subsequent processing units.
Biological Treatment
Utilizes microorganisms to efficiently degrade organic pollutants (COD, BOD), converting them into harmless substances, forming a core part of our economical and eco-friendly process.
Advanced Oxidation
Employs Advanced Oxidation Processes (AOPs) to thoroughly treat refractory organics and color by breaking down large molecular structures, preparing the stream for further treatment.
Filtration System
Equipped with multi-media or activated carbon filters to precisely remove fine suspended particles, ensuring pure water quality for the membrane system and extending its operational life.
Membrane Treatment
Leverages advanced membrane separation technologies (e.g., UF, NF, RO) to efficiently separate and concentrate substances, removing dissolved salts and organics with significantly reduced energy consumption.
Evaporation & Crystallization
The concentrated liquid is heated to evaporate the solvent. As the solute becomes supersaturated, it precipitates as high-purity crystalline products, achieving resource recovery and zero liquid discharge.
ZLD Evaporation Equipment Costing
How much does a zero liquid discharge evaporation equipment cost? In order to calculate the cost accurately, we recommend that you fill out a questionnaire and then we will be able to prepare a commercial offer, taking into account all the features of your project. We are always ready to provide you with detailed information about the different models, their technical characteristics, performance. We offer a full range of services, from advice and assistance in selecting equipment to its supply, installation and configuration. Our goal is to provide you with the necessary equipment to effectively solve the water treatment problem in your specific situation.

Easily Handle Various Complex Wastewaters
We optimize process design for different wastewater characteristics to ensure efficient and stable system operation.
Scientific and Rigorous Double-Effect Process Flow
A clear, streamlined process ensures every drop of water is treated efficiently.
Step 1
Preheating
Wastewater is preheated using available residual heat to improve thermal efficiency.
Step 2
First-Effect Evaporation
Preheated wastewater enters the first-effect evaporator and is boiled using a primary steam source.
Step 3
Vapor Transfer
The secondary steam from the first effect is directed to the second-effect evaporator to act as the heating source.
Step 4
Second-Effect Evaporation & Condensation
The liquid in the second effect boils at a lower pressure. The final vapor is condensed into distilled water.
Step 5
Discharge
The concentrated liquid is pumped out from the bottom of the evaporator for further processing or disposal.
Preheating
Wastewater is preheated using available residual heat to improve thermal efficiency.
First-Effect Evaporation
Wastewater is boiled by a primary steam source in the first evaporator.
Vapor Transfer
Vapor from the first effect heats the second effect, saving energy.
Condensation
Final vapor is condensed back into distilled water for reuse.
Discharge
The concentrate is discharged for further processing or disposal.
How it works
The working principle of a double-effect evaporator centers on reusing heat energy. It consists of two evaporators (effects) operating at different pressures. Primary steam heats the liquid in the first effect. The resulting vapor (secondary steam) from the first effect, instead of being condensed immediately, is used as the heating source for the second effect, which operates at a lower pressure and boiling point. This cascading use of heat significantly reduces overall steam consumption, making it highly energy-efficient.
1. Heating & First Effect: Material enters the first effect and is heated by primary steam, causing evaporation.
2. Vapor Transfer: The secondary steam generated in the first effect is piped to the heating chamber of the second effect.
3. Second Effect Evaporation: The material in the second effect is heated by the secondary steam from the first effect, causing it to evaporate at a lower pressure.
4. Separation & Condensation: Vapor and concentrated liquid are separated in both effects. The vapor from the second effect is condensed into distilled water.
5. Collection: The concentrated liquid is discharged from the final effect and collected.
