Sulfuric Acid Filter

In the field of sulfuric acid filtration, the vacuum disc filter is one of the most widely adopted pieces of equipment.Featuring a corrosion-resistant structure and specialized filtration media, it leverages vacuum negative pressure to achieve rapid capture and separation of solid particles in acid solutions. Widely applied in highly corrosive working conditions such as sulfuric acid production, chemical pickling, and metallurgical acid leaching, this equipment offers outstanding advantages including high separation efficiency, superior filtrate clarity, stable and reliable operation, and easy maintenance. It serves as a core piece of equipment for material processing in acidic systems.

Advantages of Sulfuric Acid Filter

1. Excellent Corrosion Resistance & Strong Adaptability

Specifically engineered for sulfuric acid systems, the entire machine housing and filtration media are constructed from acid-resistant, application-specific materials. It delivers stable performance across sulfuric acid environments of varying concentrations and temperatures, as well as mixed-acid settings. This effectively addresses the industry-wide pain points of equipment aging and damage under highly corrosive working conditions.

2. High-Efficiency Separation & Outstanding Capacity

The vacuum disc design features a large contact area, enabling rapid filtration under negative pressure. Its efficiency is 2–3 times that of conventional equipment, with solid recovery rates reaching over 98% and suspended solids in the filtrate controlled to ≤ 50 ppm. This significantly boosts overall production efficiency.

3. Stable Operation & Easy Maintenance

The machine adopts a modular layout, ensuring a compact structure and minimal floor space. The proven drive system design guarantees smooth operation and low failure rates. Filter cloth replacement is straightforward, and cleaning cycles are extended, effectively reducing daily operation and maintenance costs, as well as unplanned downtime.

4. Energy Efficiency & Environmental Friendliness for Green Production

Powered by vacuum negative pressure, its energy consumption is only about 60% of that of pressure-driven filtration equipment. The filtrate can be directly recycled, and the filter cake moisture content is reduced to below 25%. This not only cuts acid solution losses but also alleviates subsequent environmental treatment burdens, fully aligning with clean production principles.

5. Flexible Customization & Wide Application Coverage

Filter area, material combinations, and automation levels can be flexibly configured to meet specific process requirements, comprehensively satisfying diverse application scenarios across industrial production operations of all scales.

The core demand of industrial production for equipment—continuous operation and low failure rates—dictates that buyers focus more on total cost of ownership (TCO) rather than just the purchase price. The ability of equipment to operate stably over the long term and the convenience and cost-effectiveness of its maintenance directly impact production line efficiency and overall costs.

1. Equipment Reliability

Customers pay close attention to the equipment’s failure-free operation capability, which hinges on two key metrics:First, the mean time between failures (MTBF);Second, the service life of wear parts.

2. Maintenance Convenience

Key considerations include whether wear parts are easy to disassemble, replace and standardize, and whether maintenance can be performed without relying on professional teams. This avoids prolonged downtime caused by complicated maintenance procedures.

3. Failure Rate and After-Sales Service

Buyers also value manufacturers’ established after-sales service teams, failure response time, and the speed of spare parts supply. These factors are critical to preventing production line shutdowns due to equipment malfunctions.
