Key Technology Behind Loway Automated Filter Presses
Pressure Filtration Mechanics Automated filter presses use mechanical pressure to force liquids through filter media, typically filter cloths, while retaining solids. The pressure squeezes liquid from the slurry, creating increasingly dry solid cakes. Automation Control Systems Modern filter presses utilize sophisticated PLCs that control the entire operation from feeding to cake discharge. These systems monitor pressure, flow rates, and cycle times while making real-time adjustments for optimal performance. Filter Media Technology High-performance synthetic filter cloths with precise micron ratings ensure effective solid capture while allowing clear filtrate to pass through. Advanced media options include chemical-resistant materials for aggressive applications.
Technical Advantages
Secure Edge Welding
The stainless steel mesh is firmly welded to the plate edge, preventing tearing or damage during operation and maintaining filtration quality without frequent replacements.
Superior Structural Integrity
The high-strength construction maintains performance integrity even under intense backwashing conditions.
Anti-Clogging Design
The stainless steel mesh prevents adhesion of impurities and resists clogging, making it particularly effective for high-viscosity liquids and applications using diatomaceous earth filtration.
Precision Engineering
Features open-top and closed-bottom design with uniform mesh spacing on the upper surface and solid stainless steel plate on the bottom, for a tight, repeatable seal.
Enhanced Regeneration
Compatible with combined air-water backwashing systems, allowing complete performance restoration after cleaning cycles.
High Pressure Tolerance
Withstands backwashing pressures of 0.6-0.8 MPa.

Frequently Asked Questions About Stainless Steel Filter Plates
Q1: When should I choose stainless steel instead of polypropylene?
Choose stainless when the slurry is hot, solvent-laden or aggressive to polymers. Stainless plates work up to 300°C, tolerate pH 1-14, and meet food-grade requirements that polymer plates cannot.
Q2: 304 or 316L - which grade do I need?
304 covers most neutral and mildly corrosive duties. 316L is the safer pick for chlorides, acids and pharmaceutical or food contact, and both grades come from certified suppliers.
Q3: What filtration precision is available?
Mesh options run from 20 to 400 mesh. Coarser mesh handles coarse solids and support duty; finer mesh serves polishing and clarification.
Q4: Can the plates be backwashed?
Yes. The fully welded construction tolerates backwash pressure of 0.6 to 0.8 MPa, so the same plate can alternate between filtration and backwashing cycles.
Q5: How are the edges and surfaces finished?
Surfaces are polished and passivated, and the edge construction is fully welded. This keeps the sealing face stable through repeated thermal and pressure cycles.
