Filter Press

LiqTech Water’s separation solution produces high cake dryness of up to 80 % at reduced processing times. The solution is suitable for process media where high throughputs are required and good access for handling is necessary. It is a simple solution, which is easy to operate and maintain.

Moreover, the sludge dewatering system is an automated solution aided by a feed pump that generates pressure filtration. Thus, by employing a filter press for wastewater dewatering, you may also reduce the man-hours used on wastewater handling.

The filter press is made with a solid steel frame to ensure a strong and long-lasting framework. It is a simple system designed as a compact solution. It can be designed as a customized solution to match your specific separation needs.

A feed pump generates a pressure, which will send the sludge to be treated into the filter press. The pressure will push the filter plates towards the end-plate, forming a tight seal. The filter press then dewaters the sludge and delivers filter cakes of up to 80 % dry matter, depending on the pressure and application. The liquid will permeate the filter press filters, called filter cloths, attached to the filter plates, while solid will be retained. This will make the solid build up as thick layers on the filter press filters. The thicker the solid layer gets, the better it will retain smaller particles and solids, enabling an even more thorough separation process. The pressure from the feed pump will increase as the filter cake builds. Several drip trays are installed to collect wastewater, sludge, and filter cake debris dripping from the filter plates. Once the pressure reaches a set value, the filter press must be emptied. The set pressure highly depends on the application. The filter press machine can easily be opened in two stages to remove the filtered solids and for easy cleaning or replacement of filter press filters. Once it is opened, the dry cakes of dried solids drop to a tray. The dried solids can either be discharged to a significantly reduced price, reused, or sold for reuse.  

The LiqTech filter press for wastewater dewatering is made of strong and durable materials to ensure an application applicable for harsh environments with a long lifetime. It can withstand heavy-handed treatment required by many industrial processes and operations.

As we have worked with many diverse industries, we know how to separate various types of water and wastewater to obtain the best and most cost-effective results. Moreover, the required filter press filter may vary from industry to industry and task to task. At LiqTech, we know which filter press filters deliver the best separation results for various industries and applications.  

A solid and liquid separation process may require customized solutions to obtain the best dewatering results. At LiqTech Water, we design your filter press wastewater treatment system based on the type of sludge and volume to be treated. We can, among others, customize your solution in terms of the number of filter plates and dimensions. The filter press can be installed with 10-60 filter plates. Each filter plate has a filter surface area of 0.56 m² and a press volume of 7 liters. Our filter press machines can be built in various sizes, making them applicable for several applications in various industries. Likewise, we offer many types of filter cloths, depending on your type of water or wastewater to be treated. Some types of wastewater or sludge may require a thick filter press filter, while other types may require a thinner filter press filter.

At LiqTech Water, we are always ready to assist you with a customized solution, matching your specific separation needs. Our filtration experts are ready to provide recommendations on how a sludge dewatering unit can optimize your operation and whether any special features or accessories should be added to your filter press technology.

Moreover, the LiqTech filter press can easily be upgraded in order to meet ever-changing demands. This means that you can always increase your filter press wastewater treatment capacity if your production capacity changes. Likewise, you can always add extra features or accessories to your solution.
