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.

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.

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:

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.

Join Hydro International For The Vortex Flow Controls In Practice Webinar
11/11/2021
In this follow-up webinar Technical Product Manager, Phil Taylor will demonstrate in more detail how to select and design a Hydro-Brake using our free online design tool. The Hydro-Brake is one device that should be in every stormwater engineer’s toolbox. Hydro invented the vortex valve back in the 1960’s and has led the world in its development and design ever since.

Ushering In A New Era Of Sustainable Biological Treatment
9/14/2021
Conventional activated sludge treatment for wastewater is becoming increasingly problematic over time. Not only does the process require significant amounts of energy, which drives up operating expenses, but utilities are under mounting pressure from the U.S. EPA to go green.

Improve Sludge Quality With Sludge Screening
6/7/2021
Plants with Anaerobic Digestion see phenomenal performance improvements in this process when they removed rags, plastics, and inorganic solids from their digester with the Hydro-Sludge Screen from Hydro International. Learn about a few of the many wastewater treatment plants that have benefitted from cleaner sludge. Read this brochure for brief case studies of how plants have improved their overall operations as well as protected valuable process performance and capacity with the Hydro-Sludge Screen.
