Traditionally, most septic tank systems have operated simply through the anaerobic separation of waste. The sludge gets into the tank, solid waste settles at the bottom, grease and fats rise to the top and the grey water is decanted and pumped out into a leach field.
Today, more progressive alternative septic tank systems are finding their way into the market and into people's homes. So what are these alternative septic tank systems? How do they work and are they a good option? Read on to find out
What are alternative septic tank systems?
An alternative septic tank system is one that seeks to improve on what a traditional septic system does. They seek to purify waster faster and in a more environmentally friendly manner. They rely on more than just anaerobic waste treatment to refine waste water from toilets, sinks and bathrooms.
There are various types of alternative septic tank systems available today, each utilising various alternative waste treatment technologies.
- Aerated systems: Aerated systems feature vents that allow air inflow for aerobic breakdown of organic waste inside the septic tanks. The aerobic process speeds up the waste breakdown process and reduces the amount of solid waste in the tanks.
- Worm-based systems: Other alternative septic tank systems take the aerobic process further by incorporating use of worms. Worms are fed into the tanks periodically to create a natural eco system in the tank. The worms digest organic matter, further reducing the amount of waste retained in the tanks.
- Filtration-based systems: Other alternative septic tanks systems feature filtration chambers. Waste water is passed through these chambers after going through aerobic bacteria action and decantation. The filtration system sieves off any suspended solid particles, further purifying the remaining effluent before extraction into the leach field.
How are they better than traditional septic tank systems?
There are several factors that make alternative septic tank systems alluring. These are:
- Some alternative septic systems are faster. They breakdown waste quicker, reducing the need for frequent pump outs.
- Some alternative septic systems break down waste more efficiently. This means cleaner water is released for reuse in irrigation. The cleaner waste is safer for the environment because the water has been greatly purified. The effluent is also safer for leach field systems because there are no fine waste particles to cause blockage.
- Septic tank systems that use worms can treat a broad range or organic waste. They can eliminate waste such as food remains, weeds, flowers and other vegetation, thereby reducing the amount of garbage disposed off commercially.
If you're thinking of getting an alternative septic tank system, contact companies like Biosystems 2000. Also have a local health inspector approve its use before installation.
