You would think that pumping water would be easy; however, pure, clean water is not lubricating, which can be a large problem for water pumps that use the media being pumped as a lubrication to help with the sealing of the unit. This is the reason that there are many different types of seal-less pumps on the market.
The pumps are used for water treatment applications, high-pressure cleaning applications and disinfecting applications. The pumping of wastewater is much different than the pumping of clear water. Wastewater often contains abrasive solids and long fibres. Additionally, when you are treating water, a number of abrasive and aggressive chemicals are needed.
Processes Involved in Water Treatment
Wastewater and water treatment facilities often use continuous flow operations that include additional treatments along certain parts of the process such as sedimentation, vacuum filtration, storage and disposal of treated sludge and the dosing of chemicals. Additionally, certain water treatments only run once a week or once a day.
A professional waste treatment system often includes several processes that are either:
* Physical ( filtration and flotation processes)
* Chemical (chlorination and coagulation processes)
* Biological (activated and aerobic sludge processes)
* A combo of any of these three processes
There is a comprehensive range of water pump solutions, which means we can offer you the best pumping system for your facility. Industrial water pumps are designed to pump wastewater through all the different stages of the treatment process reliably and efficiently, whilst liquid dispensing.
* Sludge Treatment – Examples of sludge treatment applications include dewatering sludge pumping, stabilising sludge pumping, thickened sludge pumping, pumping of primary and/or secondary sludge, tertiary sludge treatment applications.
* Wastewater Treatment – Examples of wastewater treatment applications include pumping wastewater, controlling odors, correcting pH levels, dosing flocculant, determining polymer and feeding filter press.
Areas for Application Usage
* Water Purification – There are pumps that are available for the various stages of purification of wastewater. These are reliable and highly efficient.
* Industrial Wastewater – Residues and slurries are abrasive and corrosive, which means that this process needs a pump that can handle viscous fluids. There are many different industrial water pumps that are specifically designed to pump wastewater. These pumps are cost-efficient and only require low maintenance.
* Stabilization – The storage of sludge requires that lime is injected into the sludge. Industrial water pumps can be used to dose lime and pump sludge. These models can deliver precise doses, are leak-free and can help to protect the environment.
* Filter Press Feed – When fluid is injected into a chamber filter press system, the balance between high and low pressure can become imbalanced. Industrial water pumps offer a number of accessories that you can use to ensure a trouble-free and controlled operation. Certain industrial water pumps are designed to self-regulate to avoid buildup in the filters and deliver media to help avoid clogs and prevent the decrease of flow rates into and through the chamber.
Liquid Sludge – If you need to pump liquid sludge and other intense media for the process of floating material and dewatering, there are several compact industrial water pumps available.
Thickening – The thickening process treatment method requires a pump that is able to transfer viscous fluids. Industrial water pumps can handle the transport of particles, fibres and corrosive fluids, they can adjust to the changes in viscosity to minimize energy consumption.
* Dosing Polymers – During the separation and dehydration process, liquid polymers are added to the sludge. This process requires precise measurements during the different stages of the treatment process. Industrial water pumps have the ability to precisely dose fluids under high pressure, without shear.
* Lime Milk and Activated Carbon – Activated carbon or lime milk transfer is essential when treating wastewater. A peristaltic pump is designed to do this while maximising energy efficiency and reducing maintenance costs.
