Slide Gate Actuator for Biosolids Sludge Storage
Some storage vessels are meter discharged to downstream conveyors or pumps; however, a large percentage of hoppers are discharged to truck beds. They are called “Truck Outloading Hoppers", or Systems. Live bottom screws and slide gates facilitate outloading. The...
Should Scum Pipes Rotate in Both Directions?
Scum pipes represent one of the simplest and most economical ways to remove scum and other floating materials from the water surface in a municipal water or wastewater treatment plant. They typically operate intermittently from day to day, either manually or...
Typical Cost of a Vertical Paddle Wheel Flocculator
Vertical Paddle Wheel Flocculators (VPWF) are the most popular and economical flocculator used in water treatment plants. These flocculators are designed with 10 State Standards in mind. Plants are concerned, not only about the cost of the equipment, but also the...
Grit Classifier Internal End Bearing vs External End Bearing
Most grit classifiers employ an inclined shafted screw conveyor that rotates at a quite slow RPM and conveys grit from a hopper up and out of the water and then discharges into a dumpster or container. This shafted screw requires an end bearing assembly at both ends....
Typical Shafted Screw Conveyor Wear Parts
Screw conveyors are available in both shafted and shaftless configurations. The type of conveyor that is best for your application is determined upon the needs of your individual process. For this discussion, we will concentrate on the Shafted Screw...
Wastewater Plate Settlers Case History
Both water and wastewater projects are often challenged to make the most of their process (optimize solids removal) using existing infrastructure. The more population, the greater the need is for liquid solids separation. But, greater population can also mean less...
Top Belt Conveyor Manufacturers
Since the nineteenth-century belt conveyors have been used as an effective method for transporting bulk materials, and are now one of the most widely used and efficient means of transporting compactable and granular solids. Water and wastewater treatment facilities...
Typical Wear Parts for a Horizontal Paddle Wheel Flocculator
A couple of months ago, we put together an article on Flocculator Maintenance, outlining the importance of routine flocculator maintenance. The correct maintenance on your flocculator can result in decades of useful life. To add to those comments, we would now...
Methods of Operation for a Rotating Scum Pipe
Rotating scum pipe system is the most popular and most common option employed for collecting floating scum at municipal treatment facilities. There are numerous customized options available in the design of a system, both in materials of construction and the way you...
Pilot Testing for Water Treatment Plants Presentation
A pilot unit is designed to replicate an entire flocculation and sedimentation basin. This unit is a portable complete system that can be delivered to a plant site. A pilot unit is used for multiple applications in testing such as...
