Wastewater Management

Industrial Processing Challenges

01 | High Cost of Spent Cutting Fluid Treatment

Spent cutting fluids may contain oil, metal particles, grinding sludge, and various additives. Large volumes of waste fluid increase disposal, transportation, and handling costs, while also creating additional storage and management requirements.

02 | Continuous Accumulation of Oil and Solid Contaminants

Floating oil, metal chips, grinding particles, and sludge can accumulate in coolant tanks over time. If not removed regularly, these contaminants may accelerate coolant deterioration, cause unpleasant odors, and increase the load on downstream wastewater treatment processes.

03 | Premature Coolant Deterioration

Cutting fluid quality gradually declines as it becomes contaminated with floating oil, fine particles, and microorganisms. Frequent coolant replacement not only increases coolant consumption but also generates more spent cutting fluid.

04 | Waste Fluid Handling and Environmental Compliance

Spent cutting fluids and industrial wastewater must be handled, treated, and disposed of according to applicable local requirements. Higher waste-fluid volumes can therefore create additional demands for storage, handling, treatment, and disposal.

HC FENG Solutions: From End-of-Pipe Treatment to Source Reduction

HC FENG specializes in cutting fluid management and contaminant removal for CNC machining operations.

By combining coolant filtration, oil-water separation, ozone treatment, and regular solid contaminant removal, HC FENG solutions help manufacturers manage different sources of coolant contamination directly at the machining site.

Our approach is not simply to add another wastewater treatment process. Instead, we focus on managing contaminants directly at the machining source:

Reduce contaminant accumulation
↓
Maintain coolant quality
↓
Extend coolant service life
↓
Reduce coolant replacement frequency
↓
Reduce the generation of spent cutting fluid

Regular removal of metal chips, grinding particles, and sludge from coolant tanks can also help reduce the contaminant load entering downstream wastewater treatment systems.

BEST-1: Cutting Fluid Purification System

Filtration × Oil-Water Separation × Ozone Treatment

BEST-1 is designed for water-soluble cutting fluids. Through multiple treatment functions, it helps maintain coolant quality and control contamination during machining operations.

• Filtration | Removes suspended contaminants from cutting fluid
• Oil-Water Separation | Separates floating and tramp oil from water-soluble coolant
• Ozone Treatment | Helps control microbial growth and related odors
• Continuous Coolant Management | Supports ongoing coolant treatment during machining operations

By controlling several common sources of coolant contamination, BEST-1 can help extend coolant service life and reduce the frequency of coolant replacement.

The Value of BEST-1

Instead of waiting until deteriorated coolant must be replaced BEST-1 helps manage coolant condition during use—reducing unnecessary replacement and the resulting generation of spent cutting fluid.

FOODIE: Cutting Chips and sludge Cleaning System

No Machine Shutdown × No Electricity × Fast Cleaning × Easy Mobility

While BEST-1 focuses on coolant purification and tramp-oil management, FOODIE addresses another major source of contamination: chips and sludge accumulated in the coolant tank.

Cutting chips, grinding particles, and sludge generated during machining can accumulate in machine coolant tanks and circulation systems. FOODIE helps operators quickly remove these solid contaminants from coolant tanks, reducing the amount of contaminants that remain in the coolant system.

• No Machine Shutdown | Clean coolant tanks without interrupting normal production
• No Electricity Required | Pneumatic operation with no electrical connection
• Fast Tank Cleaning | Quickly removes metal chips, sludge, and solid contaminants
• Easy to Move | Conveniently transferred between different machines
• Reduced Contaminant Load | Helps prevent continuous accumulation of chips and sludge in the coolant

The Value of FOODIE

Remove solid contaminants from the coolant tank before they continue to accumulate—helping reduce coolant contamination and the downstream wastewater treatment burden.

Build a More Efficient Cutting Fluid Management Process

Reducing spent cutting fluid requires more than addressing a single contaminant. A practical management process should consider both the condition of the fluid and the solids accumulating in the coolant tank.

FOODIE removes accumulated chips, grinding particles, and sludge from coolant tanks, while BEST-1 supports ongoing coolant purification through filtration, tramp-oil separation, and ozone treatment.

Together, these processes can help manufacturers maintain coolant condition for longer and reduce unnecessary fluid replacement—lowering the amount of spent cutting fluid that eventually requires treatment, transport, or disposal.

When evaluating a cutting fluid management solution, manufacturers should consider factors such as coolant type, tank capacity, contaminant type, machining process, and existing filtration equipment to determine the appropriate approach.

They are not intended to replace a complete industrial wastewater treatment system required by applicable local regulations. Actual wastewater discharge and treatment requirements should be handled in accordance with local environmental regulations.
