Pumps, Screens & Clarifiers - 3 Valuable Investments For Your Wastewater Treatment Plant

If you run a wastewater biological treatment plant, you must have done your research on wastewater screw pumps, screens, and wastewater clarifiers already. These are not just a few products that facilitate the smooth operation of your plant. These are your valuable investments and you should make sure to invest in only the best quality available in the market.

Wastewater Screw Pumps

Two of the most popular types are centrifugal pumps and booster pumps. Centrifugal pump is a generic name for pumps that have one or more impellers. You should be able to find different types of configurations for different applications. These are typically electric motor driven but other drive types are also available. Centrifugal pumps are suitable for almost all kinds of liquids. They are able to handle the highest level of flow rate without any problem. You can install them to handle both dirty and clean liquids and fluids with low viscosity levels. The only thing that you have to take care of is that the liquid should not contain any air or vapor.

Booster Pumps

As the name suggests, these pumps can be used to boost the pressure in your wastewater biological treatment system. It can either be an end suction, horizontal split case, inline circulator, or a vertical turbine. This pump can function as a multipurpose stage pump with more than one impeller. All other features that you are looking for in this pump will be more specific to the application you want to put it to. This is highly suitable for potable water distribution and irrigation purposes as well.

You can utilize them in applications where the water is relatively thin and has no concentration of thickening agents such as oils or any kind of soluble debris. This means it is not really recommended for liquids with solids or any corrosive alloys and metals. Booster pumps are also highly suitable for moving liquid over a long distance. You can also use the high-pressure feature in these pumps for spraying applications and similar processes where it is required to build up additional pressure to move the liquid around.

Importance Of Wastewater Screening

You will realize how important wastewater screens are the moment you set up a water treatment plant. This is the first unit operation in all kinds of water treatment apparatuses. The screen that we are talking about here can easily retain solids found in the influent wastewater. The biggest advantage of screening is that it helps you remove all the solid materials from the liquid that can:

  • Result in long term damage to all other processing equipment
  • Reduce the efficiency of the whole cleaning system
  • Easily contaminate the waterways

Wastewater screens are primarily of 3 types based on the size of the opening and the screen element used. You can find coarse screens, fine screens and also micro screens.

Wastewater Clarifiers - Sedimentation Through History

Wastewater clarifiers are also called sedimentation tanks or settlers. These are one of the most essential components of your wastewater treatment plant. They follow the simple rule of gravity and sedimentation which helps you remove solids from the wastewater. Sedimentation is one of the most highly efficient and tried and tested methods of wastewater treatment. Wastewater clarifiers give you enough retention time so that you can slow down the water and separate all of the suspended solid particles easily.
