Water pumping sounds relatively easy, but it can be a complex procedure. Pure water is a non-lubricating liquid and can be a large problem for pumps utilising pumped media as a type of lubrication for sealing. This is one of the reasons why there is a wide range of pumps without seals in the market being used for disinfection, high-pressure cleaning, and water treatment application. Pumping wastewater is different to pumping clear water. It is common for the liquid to contain long fibres with abrasive solids; therefore, the water treatment requires different aggressive chemicals to complete the process.
Water and wastewater treatment plants typically use continuous flow operations with additional treatments used at certain points in the pumping procedure, such as chemical dosing, vacuum filtration, storage and disposal of treated sludge and sedimentation. Moreover, the procedures used as part of the water treatments operate on a periodical basis running between once each day or once each week.
Professional wastewater treatment systems combine different treatment processes that are either physical, chemical, biological or a combination of the three aspects. It is via a comprehensive range of the water pump solutions and Woodhams fabricated pump bases that are correct for the facility. Industrial water pumps are designed for wastewater pumping at all stages of treatment with high levels of reliability and efficiency. The applications include the following:
1. Sludge Treatment
The sludge treatment includes the following aspects:
- Dewatered sludge pumping
- Thickened sludge pumping
- Stabilised sludge pumping
- Pumping of primary sludge
- Pumping of secondary sludge
- Pumping of tertiary sludge
2. Wastewater Treatment
Wastewater treatment includes the following aspects:
- Pumping of waste water
- Odour control
- Correction of pH levels
- Dosage of flocculants
- Determination of polymer
- Feeding of the filter press
What Are the Different Application Areas for Water Treatment Pumps?
1. Water Purification
Water treatment pumps are typically designed for application in various areas pumping wastewater through different stages in the water purification process. This is highly reliable and highly efficient as a water treatment process.
2. Industrial Waste Water Treatment
Residues and slurries are considered highly abrasive and corrosive; therefore, specific water pumps are required to handle the highly viscous liquids. Various ranges of industrial-style water pumps have been developed to handle the dangerous and difficult to pump liquid while requiring very little maintenance and being low in operational costs.
Injecting lime into the water treatment process is crucial when faced with sludge in the water. The industrial-strength water pumps are beneficial in this situation as they help with pump and lime injection. The pump models are able to deliver accurate dosing, operate in a sterile manner and are leak-free.
4. A Filter Press Feed
The imbalance of high and low pressures in the water can happen as a result of injecting liquid into a chamber filter press system. The extended range of accessories as part of industrial water pumps ensures that this operation is controlled and trouble-free. Some of the industrial-strength water pump models are suitable for delivery of media into the press system as it self-regulates according to the pressure build-up from clogged filters; thereby, slowing down the rate of water flow through the chamber.
5. The Liquid Sludge
Industrial-strength water pumps are beneficial as compact units used for pumping intense liquid sludge. This involves the transferring of floating material in water and dewatering the pumps.
6. Thickening Treatment
A thickening treatment involves the use of pumps suitable to transfer viscous fluids. Industrial pumps are ideal for the transfer of corrosive liquid, particles and fibres while adjusting to the changes in viscosity and reducing energy consumption.
