1. What is industrial liquid-solid vacuum filtration?
Liquid-solid filtration is a process used in industries to separate solid particles from a liquid. This separation is achieved using a filter medium. The filter medium allows the liquid to pass through while retaining the solid particles. The filter medium can be made of various materials: woven wire mesh, filter cloth, or paper.
During filtration, the mixture of liquid and solids also known as the slurry, is fed into the filter.
The liquid, called the filtrate, passes through the filter medium, leaving the solid particles behind as a filter cake.
Liquid solid filtration solutions are for continuous process and under vacuum which gave better and continuous production for customers. It is a critical step in ensuring the quality and performance of the final product, whether the desired outcome is the clarified liquid or the recovered solids.
The efficiency of the filtration process depends on several factors such as the size and nature of the solid particles, the type of filter medium used, cycle times, washing steps, drying time. All the HASLER’s advanced filtration solutions are for continuous process and under vacuum.
2. Where is used liquid-solid filtration?
Industrial liquid-solid vacuum filtration is used in many continuous process industries:
- Fertilisers process: producing fertilisers with continuous phosphoric acid (P205) and potash processes. We have specific design on our filters for having better P2O5 recovery, and also avoiding dilution of the strong P2O5.
- Hydrometallurgy: We propose filtration solutions for: copper, uranium, zinc, lithium, bauxite, alumina, nickel, cobalt,
- Mining, minerals & metals process: We are involved in tailings for mine industry, washing and drying phosphate rock, and also for aluminium slags in metal process for instance.
- Fine & speciality chemicals: We can propose filtration solutions for wide range of process (soda ash, plastic production, methionine, others…) with pilot small filter for R&D until big industrial filters with very high flows.
3. What are the Top 3 industrial vacuum filtration solutions designed for continuous process industries by HASLER Group?
There is a wide range of advanced vacuum filtration solutions designed for the performance of above industrial applications. Here are some key details from HASLER Group range of products:
PHILIPPE VACUUM BELT FILTERS:
- Efficiency: high cake washing efficiency, with multiple washing zones and effective filtrate recovery, achieving over 98% recovery depending on the product.
- Operational reliability: filters built with robust materials to handle corrosive or abrasive substances, ensuring long-term reliability. Belt filter design allows easy maintenance and access for repairs or cleaning.
- Water Savings: Dedicated solutions like cloth high pressure washing ramp or belt dry support table reducing water consumption. Water recirculation from vacuum pump liquid ring, cloth and belt washing, filtrates.

VERNAY ROTARY DRUM VACUUM FILTERS:
- Availability: drum filter ensures maximum filtration efficiency with a continuous availability rate of 98%.
- Low Operating Costs: VERNAY Rotary Drum Filters are cost-effective to operate. The robust construction design, and durable components allow a long-life equipment use. The drum filter consume relatively low energy and less water for functioning.
- Versatility: drum filter can handle a wide range of slurries and solids, making them suitable for diverse applications.
- Reduced layout: Drum filter design is made for having a small footprint for similar filtration area.
- Protecting product or people: drum filter can be completely covered by a hood allowing to protect the final product inside the filter, or to protect the workers around the equipment from dangerous products.

AOUSTIN VACUUM TABLE FILTERS known as ATF:
- Good performances: this filter provides a high-quality output, optimal efficiency, no dilution or mix of the filtrates. High cake washing efficiency, optimised quantity of washing liquid, good slurry distribution to keep cake thickness constant and uniform.
- Water savings: reduced clean water requirements due to an optimised filter cloth washing system arm ramp, and recovery of filter cloth washing water, then used to wash the cake.
- Large filtration area and robustness: The maximal filtration area can be 320m². The design made with robust material, and strong civil work allows long lifetime of the filter.
