All material handling systems in a wastewater treatment plant need two things; conveyors and storage. These are two pieces of equipment that need to be designed correctly in order to operate optimally. Common questions for a material handling system are: what type of conveyor should I use, do I use a belt conveyor or screw conveyor, how to design my silo, how to design my hopper, etc. There are some key design considerations for conveyors and storage for all material handling systems.
Considerations in Selecting the Right Conveyor Option
There are two main topics needed to know when picking the best conveyor option as well as designing the right conveyor for a Wastewater application; product related and design related considerations.

Design Considerations for Conveyors and Storage: Belt Conveyor
Belt conveyors are one of the most popular styles of conveyor used in wastewater treatment plants. Belt conveyor designs allow it to be best used in dewatered sludge, wet/raw screenings, macerated screenings, or dewatered grit applications. Belt conveyors are available in both troughed belts and side wall belts.
Design Considerations for Conveyors and Storage: Screw Conveyor
Screw conveyors are another popular selection for conveyor options used in wastewater treatment plants. Screw conveyor designs allow it to be used in dewatered sludge, dry sludge/lime, macerated screenings, submerged grit, or dewatered grit applications. Screw conveyors can be offered in shafted or shaftless options.
Considerations in Selecting the Right Storage Option
There are two main topics needed to know when picking the best storage option as well as designing the right storage solution for a Wastewater application; product related and design related considerations.

Design Considerations for Conveyors and Storage: Hopper
Hoppers are square or rectangular storage vessels for wet sludge applications. Hoppers can be either shop welded up to a shippable size or they can be field welded for larger volumes. JMS has supplied volumes of up to 500 cubic yards usable; higher volumes are possible. Internal tension bars and external reinforcements are required especially on these large larger hoppers making them structurally sound and able to meet appropriately dictated seismic and wind loads. Hoppers can also be outfitted with live bottoms for distribution to either pumps or a truck load-out.
