What is dewatering?
Dewatering, in its simplest form, is the removal of water from solid material or soil by wet classification, filtration, or a similar solid-liquid separation process such as the removal of residual liquid from a filter cake by a container press as part of an industrial process. In the context of wastewater treatment, whether private or in municipalities, dewatering is the part of the process whereby sludge is reduced in volume and converted from a liquid to a solid product.

Why choose dewatering?
As the soil is dewatered, it controls the hydrostatic pressure and seepage, thereby increasing the stability of the foundation soil. So as to make them more suitable for supporting structures. Dewatering is also very necessary in construction where it is needed to lower the groundwater level and create favorable conditions for building. If overlooked during your project-planning phase, dewatering can be very costly.

Who can benefit from dewatering?
Dewatering is most often used by large wastewater treatment plants, municipalities, private citizens, restaurants, and industrial companies to separate sludge into a liquid and solid. The principal equipment used in wastewater treatment is a container press like the Sludge Mate and centrifuges. These systems are easily maintained and do not require a high degree of supervision and operator training. With a Sludge Mate, it can be custom fitted for any dewatering project and can be used by both larger facilities and smaller ones without compromising its efficiency. Primary treatment is essential prior to the dewatering. The filtrate or centrate liquid, which is separated during the dewatering process, must also be treated. This typically involves circulation to the headworks of the wastewater treatment plant.

Since we understand choosing the right dewatering equipment can be difficult, here’s a breakdown of four equipment must-haves:

Sludge Mate
The Sludge Mate is a must-have for any dewatering project. This state-of-the-art machinery utilizes a single-step process to dewater different types of sludge. The Sludge Mate is available in various models, including roll-off, trailer mounted, and tipping-stand mounted.

Oil Water Separator
Another must-have is the Oil Water Separator. This piece of equipment is a dewatering box that uses coalescing tubes for optimal water-sludge separation. 

Filter Press
Our Power Pak Filter Press helps pump liquids through a center feed into fixed vertical plates to further optimize pressure filtration. 

Container Filters
The design of our Container Filters consists of three components: the container, porous support panels, and filter media. Essentially, the space between the support panels, container walls, and floor provide a drainage area for the fluids, while the outlets on the bottom and side walls allow from gravity drainage or pump suction.
