Market of slurry pumps for OFMSW treatment is rapidly spreading. Here we explain what they exactly are, how they work, which are the main components and what are their main advantages.
OFMSW stands for Organic Fraction of Municipal Solid Waste, which is the biodegradable part of the waste generated by households, companies, and municipalities. OFMSW can be a valuable resource for producing biogas, a renewable energy source, through the process of anaerobic digestion (AD). AD converts organic matter into biogas and digestate by microorganisms in the absence of oxygen.
To optimize the AD process, OFMSW needs to be pre-treated, stored, fed, and recirculated in the anaerobic digesters. This requires special pumps, called slurry pumps for OFMSW treatment, that can handle the high solids content, abrasiveness, and viscosity of OFMSW. Pumps are also needed to transport the biogas and digestate to their final destinations. Therefore, pumps are essential components of any OFMSW treatment plant.
Different types of slurry pumps for OFMSW treatment
There are different types of pumps that can be used for OFMSW treatment, depending on the characteristics of the fluid and the application. Among them, centrifugal pumps are the most versatile and widely used. Centrifugal pumps use a rotating impeller to create a pressure difference and move the fluid. They can be classified according to the number of impellers (single-stage or multistage), the position of the shaft (horizontal or vertical) and the location of the pump (submersible or surface).
Single-stage centrifugal pumps have one impeller and are suitable for large volumes of fluids with low to medium pressure. Multistage – typically double and triple stage pumps – centrifugal pumps have two or more impellers and are suitable for fluids with high pressure or high suction head.
We also see horizontal and vertical centrifugal pumps in the market. Horizontal slurry pumps for OFMSW treatment have a horizontal shaft and are easier to install and maintain. Instead, vertical slurry pumps for OFMSW treatment have a vertical shaft and are more compact and efficient. Other types of slurry pumps for OFMSW treatment are submersible centrifugal pumps, which are immersed in the fluid and are more resistant to cavitation and corrosion. Finally, surface centrifugal pumps are located above the fluid and require a suction pipe.
