All You Need To Know: Sludge Filter Press Vs Screw Press
On the subject of wastewater treatment and sludge management, there are two primary options — sludge filter press and screw press. No one system fits all, but it is essential to learn and understand the distinction between each one of them.
Also, the sludge filter press operates by passing the sludge through a series of chambers and filter cloths to squeeze out all water. This method mechanically removes the solid from the liquid, and forms a solids “cake” suitable for disposal in landfills. In a screw press, however, the solid is forced by a rotating screw conveyor through a screen while the liquid is separated from the solids.
PICKING THE RIGHT TYPE TO FIT YOUR SLUDGE DEWATERING REQUIREMENTS
There are several factors that you will need to take into account when deciding whether a sludge filter press or a screw press is right for your sludge dewatering needs. There are two things to keep in mind, how much sludge you have and within what time frame must the sludge be treated. More time is usually needed when working with thicker materials such as sludge, making filter presses a great choice for large blossom endeavors; the screw press work faster but are not always cut out for high-volume production.
Sludge Filter Press or Twin Screw Press:
There are some pros and cons to sludge filter presses as well as screw presses. Due to their ability to remove water from sludge reliably and efficiently, sludge filter presses are widely used in wastewater treatment plants. Screw press albeit a more expensive breed to run and maintain.
Screw presses, on the other hand, are usually smaller and simpler to run making them ideal for less extensive operations or in locations with limited dimensions size. But it lacks a certain kind of dewatering ability as compared to filter presses, particularly seems not very effective when handling sludge in high volumes.
Advantages and Disadvantages Of Sludge Filter Presses Vs Screw Press
Sludge filter press can dewater the slurry of varieties of solid particles with watery content less than 95% with higher efficiency, produces cleaner kind of structures and allows lower discharge cost for more easy transportation and handling. They also have a very low waste factor in the manufacturing process, and are extremely reliable, meaning you get identical performance every time. Nevertheless, sludge filter are more expensive to maintain and this can contribute the ongoing operational expenses.
Nevertheless, screw presses are generally less expensive and easier to operate, which is why they are popular investments for smaller facilities or those on a tighter budget. Not only that but being smaller also makes them perfect for those businesses or properties with limited space in the area. On the flip side, although filter presses are more efficient at dewatering sludge than screw presses, they could result in bigger costs for disposal over time.
Guidelines for Poll Specific Dewatering System
Several things need to be deliberated when it comes to picking between a sludge filter press and the screw press. Ideally, one of your primary consideration when choosing among the best sludge dewatering equipment available is in regards to how much sludge volume you will be needing to process and how fast it needs to be done. The post Sludge filter press — suitable for high capacity operation appeared first on. But, if your operating at a small place with less space than a screw Press may be more suitable.
Do not forget to take into account the operating and maintenance costs of each system as well. Sludge filter presses are extremely effective filtration systems, though these systems do come with a cost to operate and maintain in the long-term. By comparison, screw presses tend to have a lower capital cost and are simpler to operate but may not provide the same level of dewatering efficiency.
In summary, sludge press machine and screw presses both have their pros and cons so we would recommend that you take some time to consider your needs and limitations before making a decision.
