Tube Settler Coverage in a Circular Clarifier
Tube settler coverage is the minimum required area tube settlers must cover to obtain the desired treatment. By nature of the shape, the calculations for circular clarifiers are a bit more complicated. However, the variables in the equation are standard measurements. To calculate in English units, all you need to know is basin flow in MGD, overflow rate in gpm/ft2, and clarifier diameter in ft. ...

A multi-step genetic algorithm model for ensuring cost-effectiveness and adequate water pressure in a trunk/limb mains pipe system
A water distribution network is the most expensive component of a water supply system; consequently, the overall planning, installation, and rehabilitation processes should be implemented accurately and carefully. The main issue that developing countries are facing is how to optimize the distribution network to meet increasing water demand. To tackle the issue, this paper proposes a new concept ...

Monroe Clarifier provides cost-effective expansion of manufacturing capacity via wastewater reclamation and re-use
Challenge A PVC resin manufacturing plant was looking to expand its operations without purchasing additional water supply, a limiting factor in the expansion decision. In order to do so, the plant had to clarify and re-use the process water that was being discharged from a centrifuge. This wastewater contained PVC fines that had to be removed before the water was suitable for re-use. Solution ...

50 GPM Parallel Plate Clarifier for raw water treatment at a chemical manufacturing plant
Challenge A chemical manufacturing company needed to clarify surface water that was being drawn from a local creek for use as a cooling agent in their manufacturing process. The existing system was 30-years old, corroded, and not very adept at handling solids after separation from the water. Space requirements were a limiting factor in the installation. Solution Monroe sent an engineer to the ...

City of Memphis Wastewater Treatment Plant - Case Study
The T.E. Maxon Wastewater Treatment Plant of the City of Memphis, TN has four, 180-foot diameter primary clarifiers. Clarifiers 1, 2 and 3 were built in 1980 with 54-inch diameter concrete inlet pipes. Looking forward, engineers designed the splitter box that distributes effluent to the clairfiers, to allow a fourth clairfier, which was added in 1996 with a 48-inch diameter concrete inlet. After ...

Monroe Environmental Saves Steel Mill $145,000 on Clarifier Upgrade and Meets Stringent Performance Requirements
Challenge A prominent midwestern steel mill needed to put one of its blast furnaces back online in order to increase production and keep up with rising demand. Blast furnace “C”, said to be one of the most efficient blast furnaces in the world for its size, required a large volume of water to maintain proper operation, and the mill’s existing water treatment plant was ...

Amnite k100 & k150 case study
This trial was carried out in the waste water treatment plant of a paper mill with severe bulking problems. Large amounts of suspended solids regularly overflowed from the secondary clarifier and the aerated lagoon had a scum layer of about 20cm on top. This scum layer contained a lot of filamentous bacteria. The effluent from the clarifier flowed into a river resulting in visual floating clumps ...

Hunter water`s Largest treatment plant installs Logmax® Clarifiers with Cleansweep® - Case study
Body CopyThe Burwood Beach WWTP is the largest sewage treatment system that Hunter Water operate, with a processing capacity of 44 million litres per day, or up to a population equivalent of 190000. A recent upgrade included the installation of a new secondary clarifier system. EPCO Australia were awarded the design, fabrication, installation and commissioning of a 33M diameter peripheral drive ...

Characterizing shallow secondary clarifier performance where conventional flux theory over-estimates allowable solids loading rate
The performance characteristics of relatively shallow (3.3 and 3.7 m sidewater depth in 30.5 m diameter) activated sludge secondary clarifiers were extensively evaluated during a 2-year testing program at the City of Akron Water Reclamation Facility (WRF), Ohio, USA. Testing included hydraulic and solids loading stress tests, and measurement of sludge characteristics (zone settling velocity ...
