Decanter Centrifuge & Vibrating Screen Manufacturer

This week, GN Separation completed the assembling of a batch of GNLW364 decanter centrifuges, which will soon be shipped to an overseas pharmaceutical client for use in their wastewater treatment facilities.

The Role of Decanter Centrifuges in Pharmaceutical Wastewater Treatment
Pharmaceutical manufacturing processes generate complex wastewater streams containing organic compounds, solvents, heavy metals, and biological contaminants. Decanter centrifuges, however, offer a robust solution by leveraging centrifugal force to separate solids from liquids at high speeds. This process is particularly effective for pharmaceutical wastewater, as it can handle varying particle sizes, concentrations, and viscosities while achieving high separation efficiency.
The pharmaceutical industry’s need for precision and reliability makes decanter centrifuges indispensable. These machines not only reduce sludge volume but also recover reusable water and valuable byproducts, aligning with circular economy principles.

Key Features of GN’s GNLW364 Decanter Centrifuges
GN Separation’s decanter centrifuges are engineered to deliver superior performance, durability, and flexibility, making them ideal for pharmaceutical wastewater treatment. Below are three standout features that set these machines apart:

1. Duplex Stainless Steel 2205 Construction for Enhanced Durability
The bowl and screw conveyor of the GNLW364 are crafted from duplex stainless steel 2205, a material renowned for its exceptional corrosion resistance and mechanical strength. The centrifugal casting process ensures uniform material density, eliminating internal defects that could compromise structural integrity. This results in a bowl and screw that maintain optimal balance even at high rotational speeds.

2. Tungsten Carbide Protection for Extended Lifespan
The screw conveyor’s blade is reinforced with tungsten carbide plates and spray-welded coating against abrasive wear. Tungsten carbide, known for its hardness second only to diamond, resists erosion caused by solid particles in wastewater, such as sand, silica, or undissolved chemicals. These features reduce the frequency of replacements and repairs, lowering total cost of ownership for pharmaceutical clients.

3. Triple Variable Frequency Drive (VFD) Control for Adaptive Operation
Flexibility is critical in pharmaceutical wastewater treatment, where feed compositions and treatment goals vary widely. GN decanter centrifuge addresses this challenge with a triple VFD control system, enabling independent adjustment of the bowl speed, differential speed, and feed pump rate. Operators can fine-tune these parameters in real time to optimize separation efficiency, whether processing high-solids sludge or clarifying low-turbidity effluent.

Paving the Way for Sustainable Pharmaceutical Manufacturing
By integrating advanced materials, wear-resistant coatings, and smart control systems, GN decanter centrifuges offer a cost-effective, reliable solution for an industry grappling with environmental and regulatory pressures. As pharmaceutical companies worldwide prioritize sustainability, GN’s commitment to innovation positions it as a trusted partner in the transition toward cleaner, more efficient manufacturing processes.
