Because of their aversion to light, they are found in the lower depths of pools . Two varieties of flatworms are seen in wastewater treatment processes.
How do nematodes help with oxygen diffusion?
They also aid in keeping slime porous and accessible to oxygen by tunneling through the slime. In the activated sludge process, nematodes play an important role as agents of better oxygen diffusion. They accomplish this by tunneling through floc particles.
What do nematodes feed on?
Once nematodes are firmly established in the treatment process, they can promote microfloral activity and decomposition. They feed on bacteria in both the activated sludge and trickling filter systems.
What does inactivity mean in sludge stabilization?
play an important role in sludge stabilization and serve as bioindicators or parameters of process problems; as noted earlier, their inactivity or sluggishness might indicate a low dissolved oxygen level or the presence of toxic wastes.
How big are microtubellarians?

Why are activated sludges present in relatively small numbers?
In activated sludge processes, they are present in relatively small numbers because the liquefied environment is not a suitable habitat for crawling, which they prefer over the free-swimming mode.
What are the layers of a Bida system?
The layers, from bottom to top, are 1. drainage basins placed on the floor which create an air chamber; 2. geotextiles; 3. river cobble; 4. wood shavings. The size depends on how many gallons will be applied per day as well as the contaminant level—the dirtier the water, the larger our system.
Is winery wastewater rich in sugar?
Healy: Winery wastewater is rich in sugars—worms and bacteria love sugar. The amount of worms present in our system is related to the wastewater quality—facilities that discharge water high in sugars, proteins, and fats (so wineries, milk/cheese/ice cream plants, slaughterhouses) have a very dense worm population.
When was the first commercial scale plant installed?
Healy: The first commercial scale plant was installed in 1995 by our chief technology officer, Alex Villagra. He first started studying the ability of worms to digest waste and wastewater while he was studying at the University of Chile and accredits his continued interest to the fact that "oftentimes the answers to the world's most complex problems are right in front of us—products of billions of years of research and development, mother nature shows us, through her natural processes and designs, that she does know best."
Is Healy water efficient?
Healy: It's energy-efficient. We use up to 95 percent less energy than traditional wastewater technologies to deliver the same, if not better, quality effluent. Many dischargers could spend hundreds of thousands of dollars, if not millions, each year just to power the aerators used to clean their water. Fetzer, for example, is expecting to reduce its energy consumption by 1 million kWh each year as a result of implementing our system.
Do worms filter wastewater?
Healy: Worms in and of themselves are not great at filtering wastewater. Rather, worms target the solids (or TSS) and break this waste down in their stomachs. Their excrement (worm castings) are rich in microbial activity.
Is water a waste?

What happens to midge larvae after they hatch?
The adult midge lay eggs which then hatch produc ing larvae that consume bacterial floc as they grow. After several days, the larvae undergo metamorphosis resulting in adult midge flies that start the cycle all over again. In addition to "eating" the active biomass, the larvae can cause effluent TSS problems and loss of ammonia removal efficiency ...
Do flies bite in wastewater?
In addition to "eating" the active biomass, the larvae can cause effluent TSS problems and loss of ammonia removal efficiency (nitrifiers grow more slowly than other bacteria and "wash out"). While the adult flies do not bite, they are annoying as they swarm in areas near the wastewater plant.
Can lowering DO below 2 mg/L disrupt the larvae life cycle?
While lowering DO below 2 mg/L may gradually disrupt the larvae life cycle, it comes at the risk of damaging the aerobic biomass especially when it comes to ammonia oxidation - converting ammonia into nitrate. So, we usually just use the Bt or Strike solutions.
Do bloodworms need biofilm?
Erik Rumbaugh. For blood worms to grow in potable water, there must be a biofilm somewhere for the larvae to eat. Biofilms start to grow when the chlorine residual is insufficient. I would investigate if you have biofilm in the holding tank and a way for the midge flies to lay eggs in the tank.
