High-Performance Filter Presses for Food & Pharmaceutical Industries
High-Performance Filter Presses for the Mining Industry
With the rapid development of the pharmaceutical and food industries, the importance of effective wastewater treatment has grown significantly. Pharmaceutical wastewater, in particular, presents unique challenges due to its complex components, which include toxic organic substances, antibiotics, and other high-molecular-weight compounds. These pollutants, including side-chain lipids, acetone, methanol, petroleum ether, ethanol, and cephalosporin antibiotic residues, are difficult to treat and can have a harmful impact on biological treatment systems.
At Loway Equipment, we offer specialized filter press solutions designed to address the unique challenges of wastewater treatment in both the food and pharmaceutical industries. Our filter presses efficiently separate solid and liquid components in wastewater, enabling cleaner discharge, recovery of valuable materials, and meeting strict environmental regulations.

The Pharmaceutical Wastewater Challenge
Pharmaceutical wastewater presents unique treatment challenges that our filter presses are specifically designed to address:
- Contains high concentrations of toxic organic matter, including side chain lipids, petroleum ether, acetone, methanol, ethanol, dichloromethane, and toluene
- Presence of various acid and alkali substances
- Contains antibiotic residues (including cephalosporins) that inhibit conventional biochemical treatment
- Complex components with high organic content and large molecular weights
- One of the most difficult industrial wastewaters to treat effectively
Our filter presses provide a comprehensive solution for addressing these challenges, ensuring compliance with regulatory standards while maximizing resource recovery.

Frequently Asked Questions: Filter Presses for Mining Industry
Have More Questions? Our technical team is ready to provide detailed, personalized guidance.
Q1: How does a filter press work in the pharmaceutical and food industries?
The feed slurry is pumped into the press, and the liquid is filtered through the filter plates, leaving behind solid residues in the filter cake. This process is ideal for separating organic matter, antibiotics, and other contaminants from wastewater or liquid products.
Q2: How do your filter presses handle antibiotic residues in pharmaceutical wastewater?
Our filter presses effectively address the challenge of antibiotic residues in pharmaceutical wastewater through several specialized features:
- Enhanced Chemical Resistance: Materials specifically selected to withstand the corrosive nature of antibiotic compounds and their precursors
- Multi-Stage Filtration: Capability to integrate with pre-treatment systems such as coagulation and flocculation to aggregate antibiotic residues prior to filtration
- High-Pressure Operation: Operating pressures up to 1.6MPa and diaphragm pressing up to 2.5MPa effectively remove liquid containing dissolved antibiotics
- Specialized Filter Media: Compatible with advanced filter cloths designed to capture fine particles containing antibiotic residues
- Closed System Design: Prevents release of potentially active compounds during processing
When combined with appropriate pre-treatment chemistry, our filter presses can achieve reduction of antibiotic residues to levels that allow for conventional biological treatment of the filtrate or direct discharge in compliance with regulatory requirements.
Q3: What types of wastewater can be treated using a filter press in these industries?
Our filter presses are ideal for treating wastewater that contains toxic organic substances, antibiotic residues, fermentation by-products, and high molecular weight compounds found in the pharmaceutical and food industries. They effectively filter out contaminants from fermentation broths, enzyme preparations, and other industrial liquid waste.
Q4: What is the advantage of using a diaphragm filter press?
The diaphragm filter press uses a diaphragm to apply secondary pressure, improving filtration efficiency and reducing the moisture content of the filter cake. This results in better recovery of valuable liquid and reduces disposal costs. The technology also allows for high filtration pressure, making it suitable for more challenging wastewater.
Q5: Can the filter press be fully automated?
Yes, our filter presses can be fully automated, including functions such as cake discharge and system control via PLC programs. This automation reduces the need for manual labor, increases safety, and ensures consistent, efficient filtration.
Q6: How long does a filter press last in the food and pharmaceutical industries?
With proper maintenance, our filter presses are designed to provide long-lasting performance, even under the demanding conditions of food and pharmaceutical production. The corrosion-resistant coatings and high-quality materials used in construction ensure durability and reliability over time.
Q7: How do I choose the right filter press for my specific application?
Choosing the right filter press depends on several factors, including the type of wastewater or liquid to be filtered, the required filtration capacity, and the specific industry conditions. Our team at Loway Equipment can help assess your needs and recommend the best filter press model for your application.
