A large amount of sludge is produced in the process of sewage treatment. These sludges contain a large amount of water and are very troublesome to handle. The plate and frame filter press is a commonly used device that squeezes out the water from sludge to dry it. However, sometimes when the plate and frame filter press works alone, the effect may not be particularly ideal. At such times, sludge enhancers come in handy.
What is a sludge enhancer
Sludge enhancer, in simple terms, isa kind of "magic potion" that can make sludge better treated. It contains many special components, which can react with the substances in the sludge, change the properties of the sludge and make it easier to dewater.
What good effects does it have on the plate and frame filter press
Make sludge dewatering faster
When no sludge enhancer is added, it takes a considerable amount of time for the plate and frame filter press to squeeze out the water from the sludge. Just like squeezing a very tight sponge, it's hard to squeeze out all the water at once. After adding the sludge enhancer, the sludge becomes softer, and the water is more easily squeezed out. The plate and frame filter press works much faster, which can greatly shorten the time for sludge treatment.
Increase the dryness of sludge
Sludge dryness refers to the amount of water in the sludge. The higher the dryness, the less water there is in the sludge. After using the sludge enhancer, the plate and frame filter press can squeeze out the water in the sludge more thoroughly and increase the dryness of the sludge. For instance, the original dryness of the treated sludge might have been 60%, but after applying the sludge efficiency enhancer, the dryness can be increased to 70% or even higher. After such treatment, the volume of the sludge becomes smaller, making it more convenient for transportation and subsequent processing.
Reduce equipment wear and tear
When the plate and frame filter press is in operation, if the sludge is difficult to handle, the equipment has to work hard. Over time, the parts of the equipment are prone to wear and tear. After the sludge enhancer makes sludge easier to handle, the plate and frame filter press no longer needs to work so hard, and the wear of parts will also be reduced. In this way, the service life of the equipment can be extended, and the cost of equipment maintenance can also be saved.
Practical application cases
A certain sewage treatment plant previously used plate and frame filter presses to process sludge. The daily processing capacity was limited, and the dryness of the treated sludge was not high, resulting in high transportation costs. Later, they began to use sludge enhancers and found that the speed of sludge treatment had increased, and the amount of sludge that could be processed each day was much more than before. Moreover, the dryness of the treated sludge has increased from the original 65% to 75%, significantly reducing transportation costs. At the same time, the faults of the plate and frame filter press have decreased, and the maintenance costs have also been saved significantly.
Overall, sludge enhancers are truly a "good helper" for plate and frame filter presses. It can make the plate and frame filter press work more efficiently, the quality of the sludge processed is better, and it can also save costs.
