Question: Which is the best type of screw spiral to use in your live bottom bin? Answer: The answer to this question depends on the application and your specific situation, but here are some points to help illuminate some of the benefits for both types of...
Recently we were presented with a great opportunity to make a proposal for a new $100 million dollar Design-Build water treatment plant. This plant consisted of a Preliminary Treatment System, Flocculation System, and Residuals Treatment Systems all of which can be...
Biosolids require storage for all types of materials from dried biosolid to dewatered sludge. When deciding on a biosolids storage solution there are 3 main options; hoppers, silos, and bins. Selecting the right storage solution can help keep a project in budget as...
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...
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....
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...
Troughs are a key component in water management for water and wastewater operations. They can be supplied in straight or circular configuration for use as effluent troughs, filter troughs, clarifier troughs, and sluice troughs. Careful design to meet the needs of the...
Municipal Water and Waste Water Treatment plants need to use conveyance for solids, screenings, and grit. Plants choose between belt conveyors and screw conveyors. The choice between belt conveyors vs screw conveyors comes down to what materials you are conveying....
Grit Classifiers, also known as a grit screws or grit separators, are used at wastewater treatment plants at the headworks (front end of the plant) to help separate the grit from organics and water. Grit removal needs to be performed at the headworks of plants...
One of the key components in the water treatment process, flocculation, is most effective when the functions of fluid motion, differential settling, and velocity gradient (during each stage of the process) work in harmony to achieve the ultimate goal: maximizing...
