Industrial Wastewater Engineering Since 2005
Engineering Practical Solutions for Complex Industrial Wastewater
GRELLIX combines process evaluation, testing, equipment manufacturing and project support to help industrial customers minimize wastewater, recover resources and progress toward Zero Liquid Discharge.
Who We Are
GRELLIX is the international brand of Qingdao Shuiqing Muhua Environmental Engineering Co., Ltd. Founded in 2005, our Chinese operation has developed industrial wastewater treatment processes, environmental equipment and project-delivery capabilities for customers in multiple manufacturing sectors.
In response to growing demand for liquid-waste minimization and water reuse, we expanded our work into low-temperature vacuum evaporation, scraped vacuum crystallization and integrated ZLD systems. Our role is not limited to supplying equipment: we evaluate the feed, verify technical risks and design the process around the customer’s actual wastewater and operating objective.

What We Do
Technical Evaluation
Review wastewater source, composition, variability, corrosion, volatility, scaling and crystallization risks.
Bench & Pilot Testing
Test complex streams before equipment selection and use the results to define achievable concentration and distillate quality.
Process & Equipment Design
Configure pretreatment, evaporation, crystallization, polishing, materials of construction and automation for the project.
Manufacturing & Support
Provide fabrication, factory inspection, commissioning guidance, operator training, remote support and after-sales service.
Our Operating Principles
What Customers Can Expect from GRELLIX
Our company charter reflects more than twenty years of engineering experience. For international customers, it translates into five practical commitments.
Solve Real Problems with Technology
We begin with the wastewater, the production process and the customer’s operating objective—not with a standard machine.
Earn Trust through Service
Technical communication, manufacturing, commissioning and after-sales support are treated as one continuous responsibility.
Verify before We Promise
For complex streams, analysis, bench testing and field validation come before final process and performance commitments.
Protect Integrity
We communicate limitations honestly, record problems openly and do not conceal risks that may affect the customer’s project.
Respect Natural Processes
We seek safer, more stable and more controllable destinations for pollutants, while supporting water reuse, waste minimization and resource recovery.
From the field, back to the field. No paper-only engineering—only solutions that can withstand real operating conditions.
How We Work
- Submit wastewater information — source, analysis, daily volume and treatment objective.
- Technical review — identify risks and determine whether laboratory or pilot testing is required.
- Testing and process definition — verify evaporation, foaming, scaling, corrosion and crystallization behaviour.
- Customized proposal — define process, capacity, materials, utilities, controls and expected outputs.
- Manufacturing and inspection — fabricate equipment and complete control integration and factory checks.
- Commissioning and long-term support — guide installation, start-up, training and preventive maintenance.
Built Around the Wastewater, Not a Standard Machine
Performance depends on feed composition, operating conditions and the required reuse or discharge objective. We therefore recommend water analysis and testing before final equipment selection for complex or variable wastewater.
