How Different Wastewater Treatment Applications Work

In many industrial applications, conserving wastewater is quite vital. Separating water from sludge in an industrial setup is known as sludge dewatering. During wastewater treatment, the remaining product is a concentration of sediments and water. Dewatering is purposely used to reclaim the water from the concentrated solution.

Wastewater facilities spend heavily on the disposal and handling of sludge. Today, there are great innovations and improvements in the disposal mechanisms and treatment plants that used to exist before. Some of these improved options include:

1. Centrifuges

For a long period, the centrifuge system has been used in wastewater dewatering process. There have been considerable improvements to the system over the years. These systems are known to operate at high speeds of about 3000rpm and hence require regular maintenance. Furthermore, centrifuges are designed to be managed efficiently and in a reliable manner.

They produce a dry cake, meaning that most water has been removed from the sludge material. Being self-contained means that users do not have to worry about odour control. It is highly flexible and performs well in different conditions. It is one type of equipment that can work well in all kinds of treatment applications.

2. Belt Filter Presses

Belt filter presses are equipment that has been in the industry for a long time. They are considered one of the industry standards. They are quite easy to operate, familiar to facility or project workers. However, they are not the most suitable equipment to be used as alternatives in controlling odours.

3. Inclined Screw Press

This equipment works similarly as the rotary disk press. It feeds the flocculated material into a rotating and inclined screw that operates inside the stainless-steel wedge screen. It is self-contained equipment that operates quite slowly compared to the centrifuge. Additionally, it runs on minimum horsepower in comparison to other methods. This is the reason why its operation cost is very minimum.

4. Rotary Disk Press

This equipment introduces relatively new methods in operation. The flocculated material is fed in between slow-moving screens within each disk compartment. It contains anywhere between one to six disks in each unit. The slow rotation is usually between one to three rpm and users operating it love this feature including the self-contained feature.

5. Horizontal Screw Press

This system has a close resemblance to the inclined screw press. However, the flocculated material is inserted into a horizontal rotating screen. When you need to work with higher quantities, then this is the system to go for. They were common in the pulp and paper industry until their recent adoption in the wastewater dewatering plants.

There are some things you need to consider before choosing the right dewatering equipment. You need to consult a professional service that can help you evaluate your requirements. This will help you select the perfect and most efficient system for your dewatering project.
