Product Introduction
The PP-coated filter press is a perfect example of balancing cost and performance. With its innovative “steel core, plastic armor” design, it provides excellent resistance to most industrial corrosive environments at a fraction of the cost of a full stainless-steel filter press. For many users who face corrosion challenges but also need to control budgets, this is one of the most mainstream, economical, and reliable choices.
Key Features and Advantages
This is its most essential advantage. Polypropylene (PP) provides excellent resistance to most inorganic acids, alkalis, and salt solutions, and it almost never rusts. This makes it ideal for handling highly corrosive materials such as acidic or alkaline sludge, electroplating wastewater, and chemical slurries.
Significantly lower cost compared to full stainless-steel filter presses.
Delivers the same mechanical strength and stability, with strong pressure resistance, resistance to deformation, and long service life.
Smooth surface prevents material adhesion and is easy to clean. Even if the PP layer is damaged, it can be repaired on-site (using PP welding rods) without replacing large components—making maintenance convenient and inexpensive.
Main Applications
- In the purification of photovoltaic materials (such as silicon, quartz sand) and the recovery of cutting fluid, a large amount of wastewater containing fine particulate matter will be produced.
- Zhonghao filter press can efficiently achieve solid-liquid separation, recover valuable metal powder and cutting fluid, and the moisture content of the filter cake is low, which is convenient for resource utilization.
- In the petrochemical production process, sludge with complex components containing oil and catalysts will be produced.
- Zhonghao filter press adopts special filter cloth and optimized structure, which is corrosion-resistant and has good sealing.
- It can efficiently treat such sludge, the filtrate is clear, and the separation is accurate to meet the requirements of environmental protection and discharge.
- In food processing (such as starch, juice, yeast) and pharmaceutical (antibiotics, traditional Chinese medicine extraction, fermentation liquid) processes, there are a large number of links that require precise solid-liquid separation.
- Zhonghao filter presses use materials and designs that meet food hygiene standards to ensure quality and safety, efficiently separate and recycle valuable intermediate products or by-products, and ensure the safety and quality of the final product.
- Dehydration is a key part of the biochemical sludge produced by municipal sewage treatment plants.
- Zhonghao filter press equipment has a high degree of automation and stable operation. It can continuously press the flowing sludge into dry and hard mud cakes, greatly reducing the volume and weight of the sludge, creating favorable conditions for subsequent incineration, composting or landfill disposal, and effectively reducing municipal operating costs.
- Facing the mud treatment problems caused by tailings, sand washing, etc., Zhonghao filter press has demonstrated excellent dehydration performance.
- It can compress ore slurry with extremely high moisture content into a sturdy, low moisture content filter cake, reducing the risk of environmental pollution.
- Aquaculture wastewater is rich in nitrogen, phosphorus and organic matter, and direct discharge is extremely harmful.
- The Zhonghao filter press function quickly separates the suspended solids and manurefrom the wastewater to form dry manure residue.
- These manure residues are high-quality raw materials for making organic fertilizers, which realize the resource utilization of waste.
