Pumping water sounds like an easy process. However, pure water is a type of non-lubricating fluid that is a major problem for pumps that use pumped media like lubrication for its sealing. That is the reason why there is a wide assort of sealless pumps that are available in the marketplace that are utilised for water treatment, disinfection, or high-pressure cleaning applications. It is very different pumping wastewater compared to clear water. There are frequently abrasive solids such as long fibres contained in the fluid. Many different abrasive or aggressive chemicals are needed for water treatment.
Usually, wastewater and water treatment plans are continuous flow operations, that also include other treatment at certain points of the process like storing and disposing of treated sludge, sedimentation, dosing of chemicals, and vacuum filtration. Thee are also water treatments in addition to those processes that are run periodically, such as once a day or once a week.
The Processes Involved in Water Treatment
A number of different processes are combined by a professional waste treatment system and are either:
Biological (activated and aerobic sludge processes)
Chemical (e.g. coagulation and chlorination)
Physical (e.g. flotation and filtration)
A combination of the three.
Our comprehensive selection of barrel pump solutions allows us to provide you with the right result for your facility. Due to their high reliability and efficiency industrial water pumps have been designed perfectly to pump wastewater through ever treatment stage. Applications include the following:
1) Sludge Treatment
Tertiary sludge treatment
Secondary sludge pumping
Pumping of the primary sludge
Thickened sludge pumping
Stabilized sludge pumping
Dewatered sludge pumping
2) Wastewater Treatment
Feeding the filter press
Determination of polymer
Dosage of flocculants
Areas of Application
Pumps have been designed for different applications for pumping through a number of stages in the purification process. Highly reliable and highly efficient.
Residues and slurries are abrasive, highly corrosive, and need pumps that are capable of handling highly viscous fluids. Different industrial water pump ranges are designed for handling media that is difficult to pump. They are very inexpensive to operate and require only low maintenance.
It is essential to inject lime during the sludge storage stage of the process. Industrial water pumps work well for dosing and pumping lime. They are leak-free pump models that are able to operate sterile to their environment and deliver precise dosing.
Filter Press Feed
When fluid is injected into a chamber filter press system an imbalance of high and low pressures may result. Industrial water pumps, with their extensive range of accessories, ensure a controlled and trouble-free operation. Some industrial water pump ranges are well-suited to deliver media to a press system since it is self-regulating and in accordance with pressure build-up form the filters that clog and slow the flow rate down via the chamber.
An industrial water pump is a compact unit that pumps intense media like liquid sludge as part of the transfer process of dewatering and floating material.
This thickening treatment process needs pumps that can transfer viscous fluids. An industrial water pump is well-suited for transporting particles, fibres, and corrosive fluids while adjusting to viscosity changes and minimising consumption of energy.
Liquid polymers are dosed into sludge as part of the dehydration and separation process. Precise measurement is required at all treatment stages. Industrial water pumps are able to precisely dose the fluids precisely and without shear at high pressure.
Activated Carbon / Lime Milk
Transferring activated carbon or lime milk is an essential step in the wastewater treatment process. Peristaltic pumps have been designed to deliver the highest performance with the smallest footprint at the same time. Reduced maintenance costs, reliability, and maximum efficiency are ensured when industrial water pumps are used.
