How does BioKube clean sewagewater?
The BioKube Biological wastewater treatment system is a compact biological purification system, consisting of 3 identical units. Each unit has one section with submerged filters and an aeration system (coarse bubble aeration), and one section for sedimentation.
Micro-organisms growing on the submerged bio-block® filter degrades the dissolved organic load.
The submerged filter process is known to be one of the most stable techniques for treatment of wastewater in smaller quantitiesfor up between 5 and 5.000 people. This is due to the fact, that such a system can function even though the amount of inflowing wastewater varies greatly in incoming amounts. This is the case in smaller villages, hotels, vacation houses etc.
The largest system we have designed is for 7.500 persons.
The BioKube cleaning proces Step by Step:
1. Break down of Hydrogen Sulphide.
First it is important to prevent Hydrogen Sulphide (H2S) from reaching the AWTS (Aerated Wastewater Treatment System), as this will damage or at best hamper the bacteria needed for the cleaning process in the first cleaning chamber. H2S is always produced by bacteria living in sewage water deficient in oxygen, which is the case in a pre-settlement tank. The unique process in the BioKube AWTS (See our patent) makes it possible for us to break down the Hydrogen Sulphide in the pre-settlement tank, thus preventing it from reaching the AWTS. The fact that our patented method eliminates H2S already in the pre-settlement tank reduces the bad smell of Hydrogen Sulphide in the wastewater cleaning system to an absolute minimum.
2. Break down of organic material.
The wastewater is pumped from the pre-settlement-tank (septic tank) into the first AWTS cleaning chamber at precisely timed intervals (See our patent) One of the keys to our unique and stable cleaning process is based on our precise control of the inflow of the sewage water to be cleaned. The wastewater flows through the bio filter blocks, where the heterotrophic bacteria break down the organic material in the wastewater. From here the wastewater is led through a clarification chamber, where the wastewater moves slowly, and the sludge settles through gravitation. From this chamber the water flows into the second section, where this process repeats itself.
3. Break down of ammonium/ammonia nitrogen (nitrification).
From the clarification chamber of the second section, the water gravitates into the third section. Here we find the autotrophy micro-organisms, which break down the ammonium/ammonia nitrogen. This process is called nitrification. From the clarification chamber of the third section, the treated water is discharged back into nature as cleaned. The water is now so clean, that it can be led directly into a lake or stream. You can also use it for irrigation or similar purposes.
4. Removal of sludge.
The sludge, which settles in each section, is pumped back to the pre-settlement tank (septic tank) several times a day. From the pre-settlement tank the sludge should be removed once or twice a year in order to prevent any clogging.
5. Removal of Phosphorus.
The BioKube AWTS can be equipped with a phosphorus precipitation kit, if it is required that the system removes phosphorus. Phosphorus is removed by adding an Aluminum chloride to the sludge, as it is returned to the pre-settlement tank thereby creating non-dissolvable salt, which stays in the pre-settlement tank until it is emptied once or twice a year (See our patent)
Sewage water is increasingly complicated.
In order to maintain or restore optimal conditions in our waters (streams) we have to reduce nutrients, chemicals and foreign compounds to the environment, which today are discharged with wastewater from the households.
The composition of the household wastewater is now more complex than 10 years ago. During the last decade the water consumption per person has dropped significantly. But the low wastewater flow results in a higher concentration of chemicals used for cleaning in the households.
The combination of less wastewater with a higher concentration of chemicals and environmentally foreign compounds, demands an intensified treatment process. BioKube AWTS is designed to handle such an advanced wastewater treatment process.
We use natural bacteria.
A BioKube AWTS is designed so that it employs natural principles for treating the wastewater.
In nature, our water streams treat the wastewater. This happens as the water moves and thus is aerated, and thereby is provided with oxygen. The oxygen is used by the micro-organisms, which live on stones and plants in the stream. This enhances the conditions for the microbiology to break down the pollution, which may be in the water.
No add-ons to nature.
The BioKube AWTS has optimized the process, so that the concentration of micro-organisms, oxygen and nutrients always are in an optimal balance.
A BioKube AWTS takes the normal irregularities of the flow of wastewater from an individual or few households into account, e.g. high flows in the morning and in the evening, or no inflow of wastewater at all because the family is on vacation. Irregular flows of wastewater result in a great strain on the micro-organisms during the cleansing process. BioKube’s process control unit (See our patent)balances out the flow of the wastewater over 24 hours. This is done by pumping the wastewater from the inlet-well in small quantities and regular intervals into the AWTS. The micro-organisms are therefore offered optimal operating conditions, and treat the wastewater more efficiently than in any other solutions.
See here documentation for our excellent cleaning process.
BioKube has since June 2004 had independant laboratory tests conducted on water samples from 4 BioKube AWTS every 14 days.
We perform these tests also to document that BioKube very stable and constant cleaning process is not affected by yearly variations such as winter temperatures below freezing or long vacation periods where no sewage water is produced.
BioKube performs yearly service on all installed BioKube AWTS. As part of this obligatory yearly service we conduct laboratory analyze on water samples from all plants.
We can hereby document, that the stability of our cleaning process is not affected by specific individual conditions in a house such as few or many inhabitants, individual use of household chemicals or other specifics.
