As a leading manufacturer in industrial wastewater treatment, Qingdao Conqinphi Environmental Technology Group leverages over a decade of expertise to deliver robust, high-efficiency solutions. Our skid-mounted thermal evaporator for metal finishing rinse water is engineered to tackle one of the industry's most persistent challenges: reducing the volume of contaminated rinse water to dramatically lower hauling and disposal costs. This 500 GPH unit represents a significant advancement in on-site wastewater management, offering a reliable, automated system that minimizes operational hassle while maximizing resource recovery and compliance assurance.
This evaporator is designed specifically for the demanding environment of metal finishing operations, where rinse water often contains heavy metals, salts, and other contaminants. The core principle involves using thermal energy to boil the wastewater, separating pure water vapor from the concentrated contaminants. The condensed vapor can often be reused as high-quality process water, while the vastly reduced volume of concentrate simplifies disposal. Our skid-mounted design ensures that the entire system – including the evaporator vessel, heat exchanger, condenser, pumps, and sophisticated control system – arrives pre-assembled and tested on a single structural base. This translates to a plug-and-play installation, drastically reducing commissioning time and on-site labor costs.
Key Features & Technical Advantages:
- High-Efficiency Thermal Design: Optimized heat transfer surfaces and energy recovery systems ensure maximum evaporation rates with minimal energy input per gallon processed.
- Corrosion-Resistant Construction: Built primarily with high-grade stainless steel and other compatible materials to withstand the aggressive chemistry of metal finishing effluents, ensuring long service life and low maintenance.
- Fully Automated Operation: The system is controlled by a user-friendly PLC (Programmable Logic Controller) panel. It automates start-up, shutdown, concentration control, and safety interlocks, requiring minimal operator intervention.
- Compact, Skid-Mounted Footprint: The integrated design saves valuable floor space within your facility. The unit is ready for connection to utilities (power, water, steam) and process lines.
- Scalable & Customizable: While this model is rated for 500 GPH, the design can be adapted for different flow rates or specific contaminant profiles upon request.

Frequently Asked Questions (FAQ)
Q1: What is the primary advantage of a skid-mounted design?
A: The skid-mounted design means the entire system is factory-assembled, piped, wired, and tested before shipment. This minimizes installation time and cost at your site, as it primarily requires placement on a level foundation and connection to utilities and process lines.
Q2: Can this evaporator handle rinse water with different types of metals?
A> Yes, the system is constructed with corrosion-resistant materials like 316L stainless steel to handle a wide range of common metal finishing contaminants, including zinc, nickel, chrome, and copper. For highly specific or aggressive chemistries, material upgrades can be discussed.
Q3: What happens to the concentrated waste left after evaporation?
A: The evaporation process reduces the wastewater volume by over 95%, leaving a small volume of highly concentrated slurry or brine. This concentrate is collected in a dedicated tank and must be disposed of as hazardous waste, but at a fraction of the original volume and cost.
Q4: Is the condensed water (distillate) pure enough to reuse?
A: In most metal finishing rinse water applications, the distillate is of very high purity, typically meeting standards for reuse as rinse water or for other non-potable plant uses. Final water quality can be confirmed with a feed water analysis.
Q5: What are the main utility requirements for operating this unit?
A: The system typically requires a source of thermal energy (process steam or electric heating), electrical power for pumps and controls, and a cooling water supply for the condenser. Specific requirements will be detailed in the proposal based on your selected configuration.
Q6: How is the evaporation process controlled?
A: An automated PLC control system manages all critical parameters, including feed rate, temperature, level, and concentration. Operators interact via a simple touchscreen interface for monitoring and adjustments.
Q7: What kind of maintenance does this system require?
A> Maintenance is relatively low. It primarily involves periodic inspection, cleaning of heat exchange surfaces if scaling occurs, and routine servicing of pumps and instrumentation as per the provided manual.
Q8: Do you offer units with different capacities?
A: Absolutely. While this listing is for a 500 GPH model, we design and manufacture thermal evaporators in a range of capacities, from smaller units to large-scale systems. We can tailor a solution to match your specific wastewater flow rate.
