31. Defining Lamella In The Sedimentation Process 5/23/2022

    Lamella, or lamellae, is a term frequently used when discussing sedimentation and clarifier design. Lamella clarifiers can be used in applications ranging from municipal water and wastewater treatment to various industrial applications. The primary benefit of utilizing lamella clarifiers over conventional clarifiers is reduced footprint. However, the term “lamella” is often used too broadly in the industry without clear intention.

32. Top 5 Considerations When Choosing A Flight Scraper For Your Rectangular Clarifier 5/20/2022

    What should you consider when planning to replace the flights in your rectangular clarifier? Flights are also known as scrapers, c-channels, flight boards, drag flights, and sludge pushers. Regardless of what you call them, they serve the same purpose. Flights convey settled solids to a hopper or collection pit and push surface debris into a scum removal device in a straight-line clarifier system. Although flights may all seem the same at first glance, there are some key characteristics to think about when evaluating which type you may need for your chain and scraper system.

33. Tube Settlers Vs. Plate Settlers: Comparing Lamella Technologies 5/17/2022

    Although both types of lamella sedimentation equipment operate on the same principles of solids settling, there are several notable differences between them. 

34. Comparing Sludge Removal Systems For Water Treatment Plants 5/12/2022

    Due to limited clearance and accessibility, effective removal of settled sludge beneath tube settlers has long been a challenge for plant owners and design engineers. They needed a sludge removal solution with a low-profile design that would offer flexibility during operation and maintenance.

35. Trickling Filter Technology Is Still Relevant 5/12/2022

    Trickling filters have proven to efficiently remove pollutants from wastewater since their inception, earning recognition as a technology that will continue to serve the industry well into the future.

36. Not All Sprockets Are The Same 5/12/2022

    There is a common misconception that all sprockets are the same, simply because they have the same number of teeth and run on 720-series chain. There are a number of other features that distinguish between a long-lasting, wear-resistant gear and a sprocket that needs to be replaced after a few years due to wear or failure.

37. Thermoformed Vs. Extruded Tube Settlers 5/9/2022

    Tube settlers use multiple tubular channels, which are adjacent to each other and sloped at nominal 60˚ angles, to form an increased effective settling area. This configuration allows for a shorter particle setting depth, and as the tube settler channels collect solids, they form a compact mass that promotes the solids to slide down the channel. Tube settlers are an inexpensive method of upgrading existing clarifiers and sedimentation basins by allowing increased flow rate and/or improved performance. They can also reduce the footprint of new clarifier construction.

38. Winter Maintenance For Trickling Filters 5/6/2022

    As winter approaches and cold weather sets in, both the air and wastewater temperatures of your trickling filter can drop to the single digit area, so we want to bundle it up to prevent it from catching a “cold.” It is critical to preserve heat within the filter so the bugs are happy, healthy, and keep working hard to clean up the wastewater that humans produce. Here are a few measures you can take to keep the bugs happy and your trickling filter efficient:

39. Protecting The Environment And Reducing Cost Through Improved Sludge Quality 4/13/2022

    Sassuolo WWTP operators noticed high levels of zinc in generated sludge. Here is how Kando helped prevent metal contamination, allowing the sludge to be applied for agriculture.

40. Maximizing Value In WWTP Equipment, Parts, And Services 12/21/2021

    In demanding wastewater treatment environments, even the best equipment needs some TLC every now and then. Finding the best way to approach that can have a tremendous impact on the total lifecycle cost of that equipment. Here is how planning ahead to evaluate the range of options and the best choices for the task at hand can make a tremendous difference in both the cost and continuity of equipment performance.
