Pumps for Water Treatment



Treatment of water is one of the most important processes that is carried out in today’s world. With the constant pollution of our natural water sources, it is crucial that water is treated effectively to make it safe for human consumption. More so, water bodies have been massively depleted calling for innovative ways of preserving and recycling water to ensure that people can meet their daily water needs and to provide water to industries regularly.

This is not as simple as pumping water to wherever we need it. It involves using the right equipment to ensure that water is treated effectively as well as making the process expediential. Most processes involving water treatment need the correct chemicals to treat the water and quality pumps throughout the entire water treatment process.

When treating wastewater especially, you need very dependable pipes to aid the process. This is because pumping wastewater is very different from pumping clear water. Clearwater from a borehole or water body has very little contaminants and is very close to its pure form. However, wastewater is thoroughly contaminated. It has long fibres within the fluid as well as very abrasive solids that make its treatment process an extensive one. This means that the use of aggressive chemicals must be applied to the water. Sturdy pumps that can handle these aggressive chemicals, as well as the waste fluid, must be used to ensure good and effective wastewater treatment.

In the wastewater treatment process multiple biological, physical and chemical processes take place within two main treatments of the waste fluid.

Firstly treatment of the sludge takes place.

Sludge is a wet thick, soft mixture of fluid and other solid components. This sludge is a product of the water refining process, and it needs to be treated. Treatment of sludge occurs in these stages; Dewatered sludge pumping, stabilized sludge pumping, thickened sludge pumping, pumping of primary sludge, secondary sludge pumping and tertiary sludge treatment.

Secondly, the wastewater treatment is carried out.

This basically involves; pumping wastewater, odour control, pH level correction, adding the dosage of flocculants, determination of polymer and feeding filter press.

These different processes may require different types of pumps depending on how aggressive the process itself will be and customised pump providers are here to provide you with a highly reliable air operated diaphragm pump solution.

Different pumps can be easily combined to enable to conduct accurate dosing of necessary water treatment additives before and during the treatment process of the wastewater. Peristaltic pumps are able to resist the abrasive nature of the fluids. It has a relatively high dosing accuracy and a very high suction lift as well.

To make things better it is very easy to maintain. Its design includes a reinforced long life hose that completely holds the fluid within it and this prevents the pump itself from degrading due to exposure to chemicals. As a result, the only maintenance is the replacing of the hose which is very affordable.

The pump can also work according to the suction, flow rate and discharge pressures needed and this is largely due to the use of a flow paced controller and pump only according to the plant’s demands. Peristaltic pumps will prove beneficial in the following processes:

1. Water Purification

Industrial pumps can withstand the wastewater purification process exceptionally well. They are designed to apply in the different stages of purification and remain strong and reliable at all times.

2. Industrial Wastewater Purification

Industrial wastewater is more viscous and corrosive than other wastewater. Customised pump providers design industrial pumps with materials to withstand this corrosive nature while still being able to pump the difficult fluid with ease.

3. Lime Injection

In storing sludge, it is important to dose it with lime and pump it well, ensuring that there is no leak. Industrial pumps are leak free and can deliver accurate dosing to the sludge.

4. Dosage of Polymers

During the separation and dehydration process, very accurate measurement of the liquid polymers that are dosed into the sludge is key. Industrial pumps are able to dose fluids without any shear and operate effectively even at high pressure.

5. Thickening

Industrial pumps are capable of transporting corrosive and viscous fluids, particles and even fibres while minimising energy consumption throughout the entire treatment process.

6. Liquid Sludge Treatment

Liquid sludge needs to be handled well as it has floating material. In the process of dewatering industrial compact pump can transfer such intense fluid such as liquid sludge very efficiently.

7. Chamber Filter Press System

In the chamber filter press fee, imbalances of low and high pressure may sometimes happen while in the process of injecting the fluid. Industrial pumps are accessorised with the correct mechanisms like a self-regulating system to observe and maintain build –up in pressure. This helps to ensure a safe and controlled operation environment.

8. Activated Carbon

Transferring activated carbon is a very important step in wastewater treatment. Industrial peristaltic pump design provides high performance and does little in affecting the environment.
