Step 4: Waste Water Treatment

Waste Water Treatment

Biogas - An Anaerobic Biogas Reactor is a chamber or vault that facilitates the anaerobic degradation of blackwater, sludge, and/or biodegradable waste. It also facilitates the separation and collection of the biogas that is produced. The residence time of the fluid in the reactor should a minimum of 15 days in hot climates and 25 days in temperate climates. For highly pathogenic inputs, a residence time of 60 days was factored for test conditions in the habitat. Thermophilic conditions allow for pathogen disinfectant of the waste products within the habitat (i.e. a sustained temperature over 50°C). Once waste products enter the digestion chamber, gases are formed through fermentation. The gas forms in the sludge but collects at the top of the reactor, mixing the slurry as it rises. The system will produce nutrients for the wetlands, algae and hydroponic gardens.

Hydrostatic Filter - Centrifugal force creates transverse flow patterns in a curved channel, which under certain circumstances manifest themselves as a pair of Dean vortices. As particles flow down the channel, they spiral around the Dean vortex cores while a combination of drag and shear-induced forces move them toward the channel center. Under the correct conditions (specified by channel geometry and flow rate), this dynamic causes the particles to focus into a band near the outside wall. At the end of the length of the channel, the single flow is separated into two flows: the concentrate and effluent outputs.

Although HDS technology leverages centrifugal force, it is different than centrifuges and hydrocyclones. Instead of relying on density differences between particles and fluid, HDS technology is solely based on hydrodynamic forces, resulting in a particle size dependent separation that allows for direct concentration of particles of any density, including neutrally buoyant ones.

UV - The UV filtration unit is a small stainless steel tank that has a inner housing with a UV bulb that allows the passing of water around the bulb for sanitizing and treatment of water collection systems.

Wetland - The bottom of the habitat has a constructed wetland to utilize several plants species to consume the nutrients produced by the bio gas reactor is producing from human excrement, plant wastes and broken down consumables and biodegradable habitat waste products.


<p>Love your ideas and your project. A question ... Where did you get the neat high-tech video footage of scrolling data shown in your &quot;Teaser Video&quot;?</p>
Our video guy made it worth Adobe after effects
What sort of plants are viable for aquaponics with human waste? Also what bacteria would be used?
<p>Is anybody living in this yet?</p><p>And how isolated is it from the outside?</p>
No one yet but we have some volunteers. We flooded the entire thing on accident so we had to get a replacement control board for the AC everything else survived. Crazy.<br><br>Its 99% isolated I sealed it as best i could silcone, water proof hatch, etc. Of course power is not isolated and consumtion is large. One of the main reasons we have not run for that long is cost to keep it alive...<br><br>Please vote for us in the contest just applied should be up in a day or two.<br><br>http://www.instructables.com/contest/fullspectrum2014/<br><br>Check out our website. www.haesh.com
