Dewatering may be able to make your company’s waste removal process much more efficient. According to Aqua-Zyme Dispoal Systems, Inc., it’s easier to clean and transport waste if the liquid by-products are removed first. Thus, you may be curious about the different ways in which biosolids dewatering can be done. In this article, we will show you four different techniques for this procedure.
1. Belt Press
For this method, the septage is dropped onto a dewatering belt or filtering cloth. This belt or cloth is then passed through a series of rollers, where the excess water is squeezed out of the sludge. Afterwards, the remaining sludge is scraped off, and then collected in a bin. The filtered water is then reprocessed by bringing it back to the front of the dewatering system.
2. Geo-Textile
Bags made out of high strength permeable fabrics are filled with septage. The water then permeates from the bag, leaving only the sludge inside of it. This is a cost-effective method, though it can take longer than other mechanical dewatering processes.
3. Rotary Vacuum
In this type of technique, septage is passed through a drum that has been pre-coated with a filter aid. A vacuum sucks the liquid part of the septage through a filter. The solids then stick to the outside of the drum, where they’re scraped off by a knife.
4. Centrifuge
With this method, the water is separated from the solids via the machine’s spinning action. Think of this in the same way a front load laundry machine works to get rid of water from your clothes in order to dry them.
With so many different methods for biosolids dewatering, you may find it hard to settle on the one that suits your needs most. Consult with an expert company in the field so that you can choose the process that works best for you.
