Septic tanks are very important additions to many sites. They are invaluable to industrial locations and large residential complexes, where the volume of waste often can exceed what the local municipal infrastructure provides. A local septic tank system is a great way to reduce waste bills by recycling the waste water locally. Septic tanks are also crucial for rural sites, where municipal services are lacking or not available.
You can learn about the specifics around septic tank use cases in two of our previous blogs, What is a Septic System? and What You Should Know About Large Commercial Septic Systems. But suffice to say, if you want to reduce your waste handling bill, safely recycle waste water into the local environment or service waste in areas with little to no infrastructure, a septic tank system is crucial.
Not all septic tanks are alike
But knowing you need a septic tank doesn’t answer what kind you should consider. Septic tank designs are in principle the same. Such a tank will comprise out of one or more chambers with bacteria that consume waste products. Heavy waste, such as feces, sinks to the bottom and light waste, such as oils, floats to the top.
Once these creatures are done, the water (called effluent) runs in a drainfield or french drain, but by adding a Bioreactor to the standard septic tank the effluent can be cleaned to pure enough to use elsewhere, such as irrigating plants. But septic tanks have many nuances and these matter if you want to invest in a tank that will do the job reliably for years and years to come.
Single vs Multi-chamber
The most basic septic tank is single chamber, encompassing the above process in one go. Wastewater flows in, is separated and consumed by the bacteria, then flows out again.
Here we have to admit to a small fallacy mentioned earlier: the effluent flowing from such a septic tank is far from useful. A single pass in a septic tank is not nearly enough to clean water, even for irrigation use. The risk of disease being in the water is still too high.
Another problem with basic septic tanks is they use manual overflows. This is a pipe that leads out of the tank, channel the wastewater once it reaches a certain level. More sophisticated tanks use pumps to manage flow rates.
If you want a septic tank that does a lot of heavy lifting and delivers real results, you should consider a multi-chamber system with its own pump.
How Calcamite’s BioMite Wastewater treatment systems work
We often try to dispense as objective advice as possible and not promote our own products. But one of Calcamite’s biggest sellers and proudest innovations is our Biomite wastewater treatment plant. These look deceptively like a single tank, but inside they house a multi-chamber system, including a pump.
From the inlet of the tank the first tank inside the BioMite wastewater treatment plant, is where the wastewater enters. Here the anaerobic bacteria, get to work on the waste particles. This is not dissimilar to the basic septic tank process described earlier in how waste is separated. But as the water is processed, it starts being fed into a second chamber suspended inside the main chamber.
This is the bioreactor, home to a number of columns that look a little like flattened honeycombs. These provide a large amount of surface area on which aerobic bacteria lives, enabling large populations that further consume waste in the water. The system also has a built-in pumping chamber, which moves the water as it is triggered.
The benefit of this system is not only vastly better processing of waste water,it’s also far easier to transport and install such as septic tanks. Maintenance is also much simpler and less demanding.
So when selecting a septic tank solution for your site, remember that not all septic tanks and wastewater treatment plants are alike. Multi-chamber tanks are much more effective, while single-unit multi-chamber tanks such as those built by Calcamite represent the best of all worlds.
