Packaged Sewage Treatment Plant which is known as Packaged STP. It is an ultra modern technology that wide application in industrial, commercial and residential sectors. Generally packaged plants are included screening, flow equalization unit, aeration unit, clarification, sludge digestion unit, and effluent disinfection. The Smaller Packaged Sewage Treatment systems are arrived completely assembled and ready to run at site. Larger Packaged Sewage Treatment systems are arrive as fully assembled as possible, with the major accessories ready to connect together.
First it is important to prevent Hydrogen Sulphide (H2S) from reaching the cleaning chambers in the BioKube, as this will damage or at best hamper the bacteria needed for the cleaning process in the first cleaning chamber.
Hydrogen Sulphide 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 makes it possible for us to eliminate the Hydrogen Sulphide in the pre-settlement tank, thus preventing it from reaching the BioKube.
The fact that our patented method eliminates Hydrogen Sulphide already in the pre-settling tank also eliminates the bad smell of Hydrogen Sulphide in the wastewater cleaning system.
The wastewater is pumped from the pre-settling tank (septic tank) into the first BioKube cleaning chamber at precisely timed intervals.
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 biofilter 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.
From the clarification chamber of the second section, the water gravitates into the third section. Here we find the autotrophy microorganisms, 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.
The sludge, which settles in each section, is pumped back to the pre-settling tank (septic tank) several times a day. From the pre-settling tank the sludge should be removed. This is typically done once a year, depending on the size of the settling tank. A one family system (5 PE) needs a minimum 2 m3 settling tank to require emptying once a year in order to prevent the settling from overflowing and sludge entering the BioKube.
If there are no inhabitants in the house for a long period of time then there is no waste water produced that will feed the bacteria.
This situation is taken care of by our patent of recirculation of treated water back to the settling tank. In a single house system we recirculate 750 litter / day to the settling tank. In the settling tank there is enough nourishment for the bacteria to live for minimum 12 months. This we have documented by many field tests.
The recirculation of cleaned sewage water back to the settling tank has the effect that a system will also preform nitrification.
In a standard system removalot total N is about 70 % because of the regular recirculation back to the settling tank.
The BioKube can be equipped with a phosphorus precipitation kit, if it is required that the system removes phosphorus.
Phosphorus is removed by adding a Poly Aluminum chloride to the sludge, as it is returned to the pre-settling tank thereby creating a non-dissolvable salt, which stays in the pre-settlement tank until it is emptied once or twice a year.
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 is designed to handle such an advanced wastewater treatment process. But substantial use of household chemicals which are non degradable should be avoided
We use natural bacteria.
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 microorganisms, 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.
It has optimized the process, so that the concentration of microorganisms, oxygen and nutrients always are in an optimal balance.
It 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 microorganisms during the cleansing process.
The process control unit 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 process. The micro-organisms are therefore offered optimal operating conditions, and treat the wastewater more efficiently than in any other solutions.
High or low temperatures.
The systems have also well documented cleaning qualities in both very high temperatures (example plus 40 degrees in the sun in the oilfields in Libya) or in the sub freezing temperatures in Scandinavia.
