Firefighter Mike Kruse to be remembered Wednesday

MUSCATINE, Iowa – Six members of the 11-person shift that arrived to battle a late-night house fire on a cool September night remain on active duty with the Muscatine Fire Department. Four have retired or moved on. One remains the only Muscatine firefighter to die in the line of duty.

A year and three days after 343 firefighters perished in a terrorist attack on the World Trade Center, Muscatine lost one of its own while battling a house fire. Firefighter Michael Kruse was 53-years-old and a 27-year veteran of the Muscatine Fire Department when he lost his life on the night of September 14, 2002.

Kruse will be remembered during a special service Wednesday (Sept. 14) with the laying of a wreath, placing of structural firefighting gear, and a moment of silence at the Firefighters Memorial commemorating the 20th anniversary of his death.

Kruse remains the only Muscatine firefighter to die in the line of duty, the only Iowa firefighter to lose their life while on duty in 2002 and the 131st in the state of Iowa since record keeping began in 1890.

Jerry Ewers, now the Muscatine Fire Chief, fondly remembers meeting Kruse for the first time as part of his team at Station 2, and sadly remembers the night Kruse lost his life.

“I remember that night very well,” Ewers said.

Muscatine Fire Department’s Green Shift responded to a structure fire at 10:30 p.m. on Saturday, Sept. 14, 2002, finding a wooden three-story multi-family home at the intersection of Orange and East 6th streets engulfed in flames. Kruse was one of two firefighters who were working on the structure’s roof when Kruse fell through and into the structure below. 

When Ewers arrived at the scene he issued an all-call to bring in other shifts and relieve Green Shift in containing the fire.

“The tragedy suffered by Green Shift was felt by all those who came to the scene,” Ewers said. “But it was best to relieve that shift and allow them to grieve. We still had a job to do but it was a very emotional night.”

Kruse’s dedication to job safety and protecting Muscatine residents is a lesson that can be taught to the firefighters of today and those of the future. 

His sacrifice and loss of life while on active duty, the emotional toll it took on his family, co-workers, and Muscatine residents, and the hope that Muscatine will never again experience a tragedy such as are all part of the message presented verbally or in the silent thoughts of those attending during each memorial service.

Assistant Fire Chief Mike Hartman also knew Kruse and carried his picture with him when he completed the National Fallen Firefighters Foundation Memorial Stair Climb. The significance that two tragedies come so close together for Muscatine Firefighters is not lost on Hartman.

“It is sad but also offers you an opportunity to reflect on the job, and the sacrifices they made,” Hartman said. “I look at it as a chance to kind of rededicate yourself. Mike passed in 2002 and we don’t have a lot of people on staff who remember him.”

Ewers first met Kruse in the 1990’s as a newly appointed Fire Lieutenant assigned to Station 2. Kruse was a member of Ewers’ crew along with then firefighter June Anne Gaeta.

Ewers admits that as a very young, very green fire lieutenant he was book smart but lacked the fire ground command and exposure to structure fires.

“Mike was a true teacher and mentor to me,” Ewers said. “His experience in fighting real fires, his expertise with the equipment, and his knowledge of the city helped this young lieutenant grow.”

Kruse joined the department in 1975 and was one of the first members to obtain his fire science degree at MCC. 

“He was a true firefighter dedicated to protecting property and saving lives,” Ewers said. “He was very detail oriented, liked everything clean and in its place, and took his job very seriously.”

One thing about Hartman’s relationship with Kruse is that Hartman knows that Kruse would expect him to maintain his training and safety, two things that were very important to Kruse.

“That’s one of things I reflect on at this time of year,” Hartman said. “What can I do to train a little bit more, to be a little bit safer, or to help our staff train harder and be safer.” 

Hartman said you can either focus on the negatives at this time of year or you can look for ways to become better.

“Everybody is going to be sad at the loss of life,” Hartman said. “You can be sad and focus on the negative part. Or you can be sad and ask what would Mike want. Those of us, especially those who worked with Mike, would ask that question.”

Everybody dealt with Kruse’s death in a different way. Many on staff just did not talk about the event or what Kruse meant to the department. A gap started to develop as staff left or retired and were replaced his young new hires. Hartman noted that after a while, one of the newer firefighters asked what you can tell me about the event and about Mike. 

Hartman and others realized that they had not done a good job of that, and sat down to put together a presentation to give to each shift. The two-hour presentation on the event, what went wrong, what could be done better, and what Mike was all about is now given at each new hire academy.

“You cannot undo what happened but you can use what happened and get as much positive out of it as you can,” Hartman said. “I think sharing this information with the department and the new hires helps to not only keep Mike’s memory alive but it is the right thing to do and brings them in to culture.”

Ewers spoke of the difference between commemoration and celebration during his 2012 speech. Commemorating an event, he said, is done to honor the memory of that event. Celebration is a time or rejoicing, a time to feel good about something that has happened.

“Commemorations often remind us of what we have lost,” Ewers said. “Commemorations are important, not because of the words spoken, but because of honor, courage, and sacrifice that were displayed during the time of the event itself. 

“We all know in our hearts that firefighting is a dangerous profession,” Ewers said. “Mike knew this when he was hired in 1975. Not every firefighter who responds to the sound of an alarm is guaranteed a safe return to quarters. Some will be mentally scarred for life with what we see and encounter at emergency scenes, some will be seriously injured, and some will pay the ultimate price.

“So it was with Mike Kruse on September 14, 2002 while battling a house fire at 6th and Orange just a few blocks from here,” Ewers said. “We have gathered here to commemorate that tragic event that took one of our own and left behind a painful gap in our ranks. We will continue to do this as long as the Muscatine Fire Department is in existence.”

Muscatine’s Firefighters Memorial is located at the intersection of Cedar and 5th Streets.

NATIONAL FALLEN FIREFIGHTERS MEMORIAL – Kruse is among the fallen firefighters to be honored with inclusion on the National Fallen Firefighters Memorial. 

In his memorial, his children wrote:

“Mike was a ‘True American Hero.’ He never wanted to be recognized for all the wonderful things he did. Mike always stood up for what he believed in. He was always honest‚ even though the other person did not want to hear what he had to say. Mike always followed the rules‚ unless someone gave him a direct order to do otherwise.

Mike always put others before himself. He always talked about his family which he was so proud of. Mike stood by them through thick and thin. He gave his children unconditional love. He taught them to respect other people for who they are. Mike explained to them to love life because life is short. He became their best friend. He loved them for who they are. He was so excited about his little grandson‚ who bore his name. He took time out of his busy life to spend lots of loving moments with him.

Mike always went the extra mile at home and at work. He kept track of every run he had ever been on. He stopped by some of the houses while he was out for his morning jog and checked on patients to make sure they were doing all right. He never passed up the opportunity to play in the yearly basketball game with the Special Olympics. Mike always enjoyed carrying the boot and receiving donations for MDA.

Mike was a veteran at the fire department for twenty-seven years. He was still able to keep up with some of the younger guys. He was able to give the younger firemen the knowledge he had learned over the years. He was very respected for that.

Mike was taken from us at a moment in time when his family and friends were so proud of who he was. He will always remain alive in our hearts as a ‘True American Hero.’”

WRRF has new tool to reduce nutrients, fight struvite formation

MUSCATINE, Iowa – The Muscatine Water & Resource Recovery Facility (WRRF) has a new tool to battle against struvite buildup … algae. The WRRF is taking part in a pilot study that uses growing algae as a way to reduce nutrients in wastewater.

 

“Algae is a wonderful way to take nutrients out of water,” Jon Koch, WRRF director, said. “They do that naturally anyway, taking nitrogen and phosphorus from the water to grow more of themselves.”

 

Gross-Wen Technologies, based in Slater, Iowa, developed a sustainable water treatment solution that was algae based, and a pilot program was established in early April at the WRRF and is now operational.

 

The process was developed by a graduate student and professor at Iowa State University as a way to remove the nutrients from lagoons and similar places.

 

“I was at a conference in Ames a few years ago when they presented this process,” Koch said.

 

What started as a process for lagoons attracted the interest of wastewater people and how this process could be used at wastewater plants. The thought of using algae to treat wastewater was new to the group presenting the process at the conference, and it took a few years of development to bring the costs down to a more manageable level.

 

The company visited the WRRF in 2019 and proposed a pilot program for Muscatine.

 

“We kind of lost track of the company during the pandemic but when we got slammed so badly by struvite in 2021, I called them up and said we needed to revisit bringing a pilot program to Muscatine,” Koch said.

 

The original cost for the six-month project was $100,000, but after some refinements to the process the cost was whittled down to $30,000.

 

“That is a lot more manageable,” Koch said. “During the revisit I asked them if we could get a pilot program right away and they said they could. However, it still took several months before the mechanism was delivered and installed.”

 

Struvite is a phosphate mineral crystal that is composed of magnesium, ammonia, and phosphate (referred to as MAP by the wastewater industry for the nutrient composition of struvite). Struvite is a common problem in sewage and wastewater treatment because it forms a scale in pipelines, belts, centrifuges, pumps, clog system pipes, and anaerobic digester systems. Damage to equipment, pipes and piping can lead to biosolids treatment mechanical and process failures. 

 

To reduce the problems caused by increased struvite levels in wastewater, a “Revolving Algal Biofilm System (RAMTM)” was developed for algae-based nutrient recovery from wastewater. The system also provides a cost-effective solution that can be used to comply with new, more stringent municipal and industrial wastewater discharge permits.

 

“This mechanism sits outside in a kind of greenhouse using the sun to keep the interior warm for good algae growth,” Koch said. 

 

041922 Algae System at WRRF 04 (JPG)The system uses vertically oriented conveyor belts that grow algae on their surface. As the algae grows, it consumes nitrogen and phosphorus from the wastewater while it uses sunlight and carbon dioxide from the atmosphere to rapidly grow algae biomass.

 

“The belt rotates through the effluent water and grabs nutrients from the wastewater,” Koch said. “Algae grows on the belt as it rotates up into the warm air. The algae picks up more nutrients as the belt continues to rotate back down, through the water, and back up.”

 

Algae is harvested by being scrapped off the belt, and can be used to make fertilizer, bioplastics, and biofuels, providing an additional revenue stream alongside an already more economical system.

 

“All that scraped off algae has the nutrients in it and the water that comes out has less nutrients than when it came in,” Koch said. “The mechanism also puts oxygen in the water using a six hp motor.”

 

Oxygen is needed by the bacteria to allow biodegradation to occur (breaking down the organic matter containing carbon to form carbon dioxide and water). At the present time, Koch is using three 150 hp and two 250 hp motors to add oxygen to the water. 

 

“If I can use 6 hp to add oxygen instead of 800 hp I am saving a lot of electricity,” Koch said.

 

The system benefits the WRRF by reducing the amount of nutrients in the water thus reducing the amount of struvite formation while meeting the more stringent DNR permit requirements and saving the WRRF money.

 

“So, you are meeting your permit limits for the nutrients you are required to take out, you are saving electricity, you are reducing struvite formation, you are reducing the amount of solids because it will pull solids out as well, and you have a revenue source,” Koch said. “This system kind of hits on a lot of different goals that we have.

 

Koch noted that using an algae-based system to remove nutrients from the water would quickly pay for itself.

 

“The savings you would have on energy reduction, and on the amount of time, energy, and chemicals used to prevent struvite formation along with the additional revenue from algae generation make this technology affordable,” Koch said.

 

But it is not only in the benefits of nutrient reduction to prevent struvite formation and to meet DNR permit requirements that make the system practical.

 

“This will be a really good compliment to the watershed work,” Koch said. “What this system can do for us as far as struvite removal is key, but you don’t have to do the whole thing (nutrient removal) at the plant.”

 

Koch noted that it would take an acre or more of these systems put together to do all the nutrient reduction and the cost would be pretty high.

 

“But if you scale it just where you need it, just enough to affect your struvite reduction and everything else, then maybe you can get most of that reduction done at the plant,” Koch said.

 

And whatever you cannot get done at the plant, then you can go out to the watershed, put in prairie strips and things like that, and do other watershed work which is really inexpensive but beneficial to the entire watershed.

 

“Muscatine city, the watershed as a whole, and the entire city basin will benefit from what we are starting to do at the WRRF today,” Koch said.
