Easier ammonia measurement

June 16, 2020

Iowa's revised water-quality standards are forcing some lagoon systems to face tougher limits for ammonia than they're used to observing. If you're in that boat, consider ATI's Q46N dissolved-ammonia monitor, which permits you to monitor ammonia with a simple, on-line monitor. The system is simple and compact, and it costs a lot less than competitive instruments. Contact us for specs, pricing, and options for a trial installation.

A free tool for budget savings

June 12, 2020

It's becoming clear that many municipal budgets are going to be under stress in the coming year, as the pandemic raises many costs while it also cuts into revenues. It's not always easy for water and wastewater utilities to cut operating expenses while remaining in compliance, but nobody wants to cut salaries at a time like this, either. We'd like to offer access to a tool that might help.

Thanks to our new relationship representing Hoffman and Lamson blowers to wastewater customers in Iowa, Nebraska, and South Dakota, we can offer you access to audits of energy use that can uncover major aeration blower power savings and help with cost reductions. Typical wastewater sites can experience an energy savings of 20% or more by taking action based on these audits. (Find out what's involved.)

In addition, incentives can help fund recommendations from our audit. These audits are a $3,995 value, but for a limited time, we can have those charges waived and offer audits to qualified plants for free. We would be happy to present this to you and discuss further, so please let us know if you are interested.

We realize that due to Covid-19, most site visits are restricted. We can provide you with a program overview and all of the information you require to make an informed decision on the value to your plant via a video presentation over Skype, Zoom, or Teams at your convenience. Then, when the time is right for travel, we can get your energy audit on the calendar.

Our team wishes you good health and safety at this time. Please let us know anytime if we can be of service to you.

Hoffman and Lamson bring more than 100 years of experience in quality and innovation to your blower needs. Contact us to get started.

A simple diversion

June 11, 2020

For those applications where simple flow diversion is needed in an open channel, stop gates are an economical measure for getting the job done. We have supplied Golden Harvest stop gates and frames on projects serving in applications like headworks (where they can be used to isolate a channel containing a mechanical bar screen or a grit trap, for example) and disinfection systems (where a UV disinfection channel might need to be taken out of service for lamp replacement), but also in flood-control and storm diversion applications as well. Aluminum and stainless steel construction are both available. Contact us for more information on stop gates anytime.

Biological nutrient removal (BNR) aided by baffles

June 10, 2020

For those operators and engineers looking to improve biological nutrient reduction by separating aerobic from anoxic zones, we would like to highlight the effectiveness of creating that separation by using tank baffles from Environetics. They're literally flexible (in the sense that they're mostly composed of geomembranes), of course, but they're also installation-flexible -- they can be retrofitted into existing concrete structures or moved, altered, and adapted to suit changes in condition. The pricing is highly economical, the materials are durable and long-lasting, and the installation process is much easier than for any other type of control structure. Contact us for more information.

Virus detection at the wastewater treatment plant

April 13, 2020

A story in Water and Wastes Digest says that a Dutch city of 150,000 found evidence of coronavirus in its wastewater before any cases had been otherwise detected in the city, just a week after the virus was first detected in the Netherlands.

The good news: This suggests that wastewater-level detection could provide useful surveillance to public-health experts as an accessory to the test, isolate, and trace protocols being discussed as the best means of dealing with the virus until vaccines are available. More information gathered at the community level can help identify hotspots that might be experiencing asymptomatic spread.

The bad news: It still isn't clear whether the virus can actually be transmitted in wastewater, either in the liquid flow or otherwise. Drinking water remains safe, but we also need to show concern for the public-works employees responsible for the collection and treatment of wastewater. They are invisible -- but essential -- front-line workers protecting public health, and they need adequate protection, too!

We have always believed that one of the most important ways to protect workers in the wastewater sector is to keep them in safe, above-ground locations wherever possible -- where fresh air and limited exposure to sewage can preserve their health. With the uncertainty surrounding the transmission of COVID-19, that's suddenly more true than ever. See our presentation "Revenge of the Mole People" for a list of 25 related reasons why it's important to keep wastewater workers above-ground (or as close to the surface) as possible, and 10 ways that lift stations can be designed to maximize that potential to stay high, safe, and dry.

Update to the diaphragm pumps in our online store

April 6, 2020

Our online store section featuring portable diaphragm pumps has been freshly updated. These are great machines for moving fluids that don't like to flow easily -- mud, slurries, sludge, and the like. They're great for in-plant applications at WTP and WWTP facilities.

Straight centrifugal pumps

April 2, 2020

Newly updated on our website: AMT heavy-duty straight centrifugal pumps. These tough little pumps come in 2" and 3" sizes and are great for applications like circulation and industrial fluid transfer. Order them online anytime, day or night, through our online store. Most are ready to ship in about two business days.
