Bio septic tank and it's advantages in gas and fertilizer production

In the agricultural sector, the importance of Bio Septic Tanks when it comes to gas and fertilizer production cannot be overemphasized. 

Aside from them been used as a channel through which domestic wastewater flows for basic treatment, it has vital roles it plays in the agricultural sector.

In this article, we’ll be discussing Bio septic Tank and their advantages. You will also learn about how it works and its possible disadvantages. 

Let’s start with the definition!

What are Septic Tanks?

A Septic tank is one of the major components of a compact bio sewage treatment system. Basically, it's made of one or more concrete, fiberglass, and plastic tanks of between 4000 and 7500 liters which is 1000 to 2000 gallons. 

It is more like a two-designed chamber through which domestic wastewater flows for basic treatment and gets ready for technical purposes. One end is connected to an inlet wastewater pipe and the other to a septic drain field.

Note, waste is segregated into 3 layers: Scum, Liquid, and Sludge. The liquid enters the first chamber, giving the solid waste space to settle for anaerobic digestion and scum to float. Further, liquid water flows to the second chamber through a pipe that is connected inside the tank for treatment by the microbes. 

Once it is treated, it is drained from the outlet into a leach field known as a septic drain field or seepage field. 

For sludge, they are the unwanted wastes that did not decompose during the anaerobic digestion process. These sludge are removed from the septic tank because if left in the septic tank may clog the drain field or decrease the soil porosity which will require a huge sum of money to fix.

How it Works

The process begins when wastewater from the toilets, kitchen, bathrooms, and laundry flows into the tank. In the tank, the solid waste settles. The naturally occurring bacteria then begin to break it down gradually. 

Overflowing wastewater now enters the aeration tank. To grow aerobic bacteria, the air is diffused into two aeration chambers.

Bacteria decompose waste into water and carbon dioxide. There would be no odor since the aerobic bacteria are breathing this oxygen. Finally, a small amount of chlorine is applied to destroy any bacteria that survived the aeration process.

You can now garden with filtered water. Plants are the perfect way to absorb nutrients that should not be discharged into rivers and streams.

Benefits of Biological Septic Tanks

Many people use septic tanks because they do not have access to a public sewage system or choose to use a septic tank because of its many advantages. 

When looking for an effective water treatment solution, septic tanks can be a great option. These are only a few of the benefits of a septic device:

    • Septic tank is used for the complete cleaning of domestic and sewage biological means

    • They are cheap to maintain. 

    • septic tank is applicable in clay soil and soil with the presence of groundwater.

    • There is no overflow of chambers during simultaneous operation of a washing machine, taking a shower, washing dishes.

    • There is no need for a well for additional filtration of the effluent; they are biologically safe.

    • Bio Septic Tanks occupies small space

    • The system is easy to operate. So, it doesn't require highly trained personnel to operate. 

    • It is an excellent option for rural communities, buildings, parks, and motels.

    • Septic tanks do not require electricity for the process, unlike sewage treatment plants. 

Generally speaking, septic tanks are a great option. But even at that, they can be challenging for their users when poorly maintained. These challenges pose disadvantages or drawbacks. Some of them include:  

    • Septic tanks may contaminate water used for human consumption. 

    • If not properly maintained, there are foul odors that can clog on the septic systems. 

    • Poorly maintained septic system can be a breeding ground for flies and insects that can transmit infectious diseases that can put in danger you and your family’s health.

    • It can cause soil contamination 

    • There is a risk in rainy seasons that the septic system overflows bringing sewage to the surface

    • Furthermore, septic tanks require more responsibility and regular maintenance

How to Maintain Septic Tanks

Considering the delicate ecology we have, septic tanks should be properly taken care of. 

First, it is important not to discharge or dispose of harsh chemicals into a septic tank for any reason. 

And the wastes- Scum and Sludge must be regularly monitored to make sure that a septic tank delivers all the time. 

In regards to one of the major challenges about septic tanks which is the solid wastes passing through the tank instead of remaining there for required retention due to overflow of solid wastes, it is expedient the tank is emptied every 2 to 5 years. 

For emptying of the tank, Motorized Emptying and Transport technology or Human-Powered Emptying are two great options that can be considered. 

Note, this must be done to ensure that sludge is not spilled around the tank during emptying, as the removed sludge from a septic tank includes fresh sludge and presents a risk of transmission of diseases of fecal origin.

Alternatively, a Bioclean Septic can be used for septic tank maintenance too.

What is Bioclean Septic?

Bioclean Septic contains enzymes and bacteria, take the dosage and mix with water, pour it inside your WC, the bacteria now spread over the plumbing system and starts to eat the gunk in thick waste, they biodegrade the waste then gets to the tank inside the tank, they multiply, fasten the sludge breakdown to maintain a sturdy septic tank. 

That bio-clean septic can be used every month in a trouble-free healthy septic tank. Note, most of the sewage from septic tanks is used as manures and fertilizers.

Septic Tank

A septic tank is a very simple device, essentially it’s a trap for solid waste with a run-off for wastewater and because it’s cost-effective it remains a very popular solution.

What will you need to install a septic tank?

First of all, you will need to find out whether you are allowed to discharge from a septic tank to the ground (via a soak-away).

For this, you will need to perform some percolation tests in the ground to establish if your ground conditions will cope with the wastewater discharged from the septic tank. Because this wastewater is untreated, the Environment Agency is quite strict about where you discharge, and here are the requirements:

Your septic tank soak-away must be at least:

• 10m from a watercourse or ditch

• 50m from any water abstraction points

• 15m from any building

• sufficiently distant from any other soak-away, including roof water

• 2 meters from a boundary

The soak-away or drainage field area should be downslope of any groundwater sources and no water supply pipes or underground services should be within the soak-away area. No access roads, driveways, or paved areas should be within the soak-away area.

The water table or bedrock must not, at any time, be within 1 meter of the bottom of the soak-away pipe itself. This usually means it has to be a minimum of 2 meters below ground, at all times. No rainwater must be allowed to enter the septic tank system.

Having understood the septic tank concept, benefits, drawbacks, and process of installation and maintenance, let’s proceed to help how septic tank wastes can be used in the production of fertilizer.

Septic Tank Wastes in Fertilizer and Gas Production

According to research, sewage sludge, waste scum and liquid serve as a source of fertilizer for gas production. It is believed that there is an eco-friendly process that enables the recovered salts to be converted directly into organic food for crop plants.

Septic tank wastes is an alternative to one of the major element use for plant and human food production – Phosphorus. Due to the relevance of this mineral element which has increased its price, many farmers find it difficult to afford it.

Thereby going for the local resources, which are found in plentiful supply in the wastewater from sewage treatment plants and in the fermentation residues from biogas plants.  

In conclusion

Bio Septic Tank produce has in the long run been an alternative phosphorus most farmers use in today’s agricultural activities. And this is one truth that can’t be neglected.
