In this post, we will reveal the importance of motor pumps and how they ensure the efficient functioning of direct and indirect water reuse systems.
The scarcity of fresh water and the need for more sustainable practices have driven the adoption of water reuse systems. Above all, what is the fundamental component of these systems? You guessed right: motor pumps! Imagine them as the heart of a water reuse system. Responsible for pumping, they are mainly responsible for ensuring the circulation and pressurization of water throughout the entire process.
Particularly in the context of water reuse systems, pumps perform specific functions of:
- Capture: they suck water from alternative sources, such as cisterns, rainwater reservoirs or treated effluents, pushing it to the subsequent treatment stages.
- Treatment: provide adequate flow and pressure for the various treatment processes, such as filtration, demineralization and reverse osmosis, ensuring the quality of the reused water.
- Distribution: distribute reused water to consumption points within the industry, ensuring the pressure needed to meet the demands of different applications.
Direct and Indirect Reuse: What’s the Difference?
In direct reuse, the system treats the collected water and reuses it immediately afterwards for non-potable purposes, without releasing it into the environment. In these cases, the motor pump will certainly be involved in the following processes:
- Collection and transfer, pumping treated wastewater directly from treatment tanks to points of use; and
- Pressurization, ensuring that water is supplied at the appropriate pressure for end use.
Direct reuse includes, for example, irrigation of green areas, washing vehicles, cooling equipment and use in other industrial processes that do not require drinking water.
In indirect reuse, we release wastewater into the environment (rivers, lakes or aquifers); later, we capture it again for use. In this way, the motor pump can participate in the processes of recapturing and reintroducing water into the environment.
How do Reuse Systems with Motor Pumps Work?
- Collect: The water used is collected from industrial processes or other sources.
- Treatment: The water goes through a cleaning process to remove impurities.
- Pumping: The motor pumps come into action, moving the treated water to the points of use or to reintroduce it into the environment.
- Distribution: Water is distributed as needed, either directly for use or released into the environment for future recapture.
Choosing the Ideal Water Pump
In short, choosing the right motor pump will depend on several factors such as:
- Flow and pressure, because, primarily, the pump needs to have the capacity to meet the system demand and the characteristics of the reuse system.
- Type of water, that is, the pump material must be compatible with the type of water to be pumped (potable, grey, treated effluent).
- Material, after all, for reuse systems, it is best to opt for equipment with materials resistant to corrosion and wear, such as stainless steel or cast iron.
- Energy Efficiency, therefore, opt for pumps that consume less energy.
Pump Performance
The performance of pumps in water reuse systems is certainly measured by their efficiency, flow capacity, and pressurization capacity. Therefore, it is necessary to select and size the pumps correctly so that the specific demands of each system are met.
The nature of the water, whether residual or treated, the pumping distance and height, and the pressure and flow requirements are factors that determine the type and power of the motor pump to be used in reuse systems.
Common Problems and Solutions
- Clogging: Suspended particles in the water can clog pumps. Therefore, use filters and pre-treatment systems to remove particles that may clog the pump.
- Corrosion: Exposure to chemicals and wastewater can cause corrosion on metal parts. Therefore, choose resistant materials such as stainless steel or special coatings and perform preventive maintenance.
- Cavitation: This occurs when vapor bubbles form, which can damage the pumps. Therefore, adjust the system pressure to prevent vapor bubbles from forming.
- Wear: Continuous use can lead to wear and tear on pump components, so schedule and perform preventive maintenance to replace worn parts.
