Combining Biosolids Waste Streams? Not So Fast…
7/12/2019
The idea of combining two systems into one sounds like a common-sense solution to simplifying operations. Wastewater treatment plant operators have been experimenting with this concept by combining waste activated sludge with primary and septage waste streams with the goal of lowering system complexity. The reality of these efforts is proving, in many cases, to be problematic.

Sludge Thickeners: The Good, The Bad, And The Smelly
7/11/2019
Management of wastewater sludge is a core responsibility of treatment plant operators. With this responsibility comes common challenges that must be overcome. These include controlling odors so as to have a minimal impact on the surrounding community and minimizing hauling costs for its disposal. Getting a handle on both of these responsibilities and more can be much easier with the proper sludge-thickening equipment.

Sludge Sampling For Polymer Selection — Critical For Project Success
7/10/2019
Polymers — the chemicals used in wastewater to thicken sludges and facilitate the removal of water — are critical to the operational efficiency of sludge-thickening equipment. Unfortunately, it’s common practice at treatment facilities to order and install equipment before even considering what the ideal polymer might be for the sludge produced at the specific plant. This flawed process is time consuming, disruptive to plant operations, and can become very costly.

How To Boost Wastewater Treatment Capacity Within An Existing Footprint
7/9/2019
Municipalities can find themselves in a real bind when wastewater treatment operations are strained by population growth. That’s because facilities are either landlocked and can’t expand at their current location, or the prospect of building an addition isn’t in the budget. When the bottleneck is at the digesters — the tanks where microorganisms break down waste — there are some commonsense strategies treatment plants can employ to address those growing pains.

FlexRake Bar Screens At 24+ Sites Around Houston Were Unaffected By Hurricane Harvey
9/11/2018
Despite the destruction of Hurricane Harvey in August 2017, Duperon wastewater screening systems in the cities of Cuero and Refugio, Texas – approximately 150 miles southwest of Houston – were virtually unaffected by the storm. Duperon’s FlexRake bar screens, installed at both locations as well as dozens of other sites in and around Houston, remove objects like rags, paper, plastics, and metals to prevent damage and clogging of downstream treatment equipment. Both communities found essentially no damage to their wastewater screening equipment.

STRAINPRESS® Helps Fort Worth Turn A Liability Into An Asset
7/25/2018
Scum is not a substance that anyone in a wastewater treatment plants wants to deal with. Scum, the greasy substance that floats to the surface of clarifiers, gets nastier as it accumulates. Some smaller wastewater treatment plants mix their scum back into other processing streams while other larger plants treat their scum separately. The City of Fort Worth takes a unique approach in managing its scum and now turns what was once a liability into an asset.

Solving The Headworks Screening Challenge Of Fitting In Tight Spaces
6/22/2018
Oostburg’s Black River Falls facility is a lean operation with limitations in space for screening technology and in the staff resources available to manage, maintain and report on the Village’s processes. Even though space was limited, Oostburg knew that putting a headworks screening solution in place would improve their operational efficiency. Oostburg found the perfect solution using the Huber Technology RoK4 confined space vertical screen.

FlexRake® Celebrates 20 Years Of Continuous Operation In Michigan
4/26/2018
In 1997, back before text messaging and cell phones, Duperon Corporation installed the FlexRake FP Full Penetration Coarse Bar Screen into its first wastewater treatment plant at the City of Adrian, Michigan. The same equipment is in operation today, with all of its original components, with the exception of a motor/drive head bearing replacement.

4-Step Wastewater Sludge Treatment Process
4/3/2018
Sewage sludge is a byproduct of treated wastewater. It is composed of both organic and inorganic materials, a large concentration of plant nutrients, organic chemicals, as well as pathogens. Therefore, it is extremely important to properly treat such sludge in order to minimize its environmental repercussions.

Cardston’s Community Relationship Improves With Dewatering Technology Choice
12/21/2017
Cardston WWTP’s choice of a dewatering system to replace its belt press, Huber Technology Q-Press®, has a striking comparison to the plant’s previous technology in both the footprint and the attention it requires. The Cardston staff also noticed striking improvements in water separation, end-product dryness and offensive odor by-product. Read more about how the Q-Press® helped Cardston become a better neighbor.
