Composite wastewater treatment package
Before we want to explain about the composite wastewater treatment package, we want to introduce you to the meaning of composite: it is called combining several materials or composite materials. In fact, if there are two phases in the matrix and approximately five percent of the phase Second, this word is used.
Composites consist of two phases: Main phase and booster phase.
Usually, in the composite structures, composites show new properties compared to their raw materials. The reason why composites are made is because the new material obtained from the raw materials is lighter, more resistant and even cheaper. .
In industry, composite materials that are widely used include:
1- Wood composites such as three-layer composites
2- Ceramic matrix composite
3- Reinforced plastics such as polymer reinforced by fiberglass or fiber
4- Masonry and reinforced concrete
5- Metal matrix composite
6- Other advanced composite materials
What is fiberglass?
Fiberglass is a type of plastic (polymer) that is reinforced with fiber and is considered a composite material that is reinforced and made with fibers. The type of these fibers in fiberglass and in polymers reinforced by carbon fiber are made of carbon, and the other type of these fibers are basalt or aramid. On the other hand, other types of fibers are also used, which include wood. It is paper or asbestos. The type of polymers is vinyl ester, epoxy or polyester. In the air and space industries, phenol-formaldehyde composite resins are used, which are used in making ballistic armor.
Consumables of composite materials
In general, it can be said that composite materials are used for:
- the buildings
- Storage tanks
- Making boat hooks
- Swimming pool signs
- Marble sinks
Composite wastewater treatment package equipment and… is used
More advanced composites can even be used in airplanes and spacecraft.
Industry application of composite wastewater treatment package
Using different types of it for chemical treatment of wastewater such as:
- Activated carbon composites
- Composite composites
- Oxide-based composites
- Polymer composites
- Biosorbent composites and…
For example, for the treatment of industrial, sanitary, hospital, etc. heavy metals such as: lead, zinc, mercury, nickel, and copper, the physical treatment is done first, and then the composite wastewater treatment package is used. It is considered as the second stage. In this method, the removal of chemicals and pollutants is very cheap, high-quality and even completely effective.
- In this method or the second stage, a composite wastewater treatment package is used. In this method, all the treatment is done in the same way as other treatment packages. The only difference between the composite wastewater treatment package and other packages is in the treatment units and the type of tools. It is the body. Fiberglass is used in the composite sewage treatment package.
If you ever want to buy a composite sewage treatment package, you will come across the abbreviation GRP, in fact, it is the general modification of FRP and conveys the concept of fiberglass, so know that they both mean the same thing and are of the same type.
Various and common fiberglass or FRP products
Most of the FRP products are cylindrical, such as: Piping systems, storage tanks, chimney liners, duct systems, etc. One of the unique features of fiberglass is that they can be combined with other elements such as carbon, which results in The uses of this product will increase, on the other hand, it has been distinguished due to its unique features such as insulation, smoothness and even lightness.
The quality of the composite wastewater treatment package
As you know, a composite sewage treatment package should have high efficiency, light weight, high quality, high durability and easy installation, all these features are available in the composite sewage treatment package. Is.
The composite wastewater treatment package can be used in the treatment of industrial wastewater and sanitary wastewater, etc., and it is completely cost-effective, and due to the presence of FRP, it is resistant to corrosion and at high pressures without leakage and very resistant.
How does the unit work?
The working principle of these units is such that it completely destroys arsenic, fluoride, suspended, iron, and ammonia substances. And it even helps the growth of microorganisms a lot (microorganisms actually remove and digest existing pollutants, parts have been used in these units that help purify and clean sewage and sedimentation a lot slow
سیستم بی هوازی ABR
It is called an anaerobic baffled reactor. In this unit, you can see chambers where pollutants and wastes are treated. These chambers have advanced septic poison. It can be said that ABRs have a very high purification efficiency and are very resistant, that’s why their use is highly recommended for wastewater treatment. If during the purification process, materials such as sludge are left behind, a separate operation should be considered for it.
Advantages of using anaerobic system
1- It does not need any electrical energy.
2- They have a long life.
3- Their operating cost is very low.
4- Very resistant to pressure and electrical load
5- One of the features of this system is that it can be installed underground and will not need a separate space.
6- In this process, the resulting sludge is very small and will stabilize it.
7- Reducer of BODs
Disadvantages of anaerobic system
1- It does not have a high ability to reduce factors such as pathogens.
2- It needs a specialist for design and construction.
3- It needs water to wash.
4- In this system, due to the remaining sludge, it will definitely need more purification.
5- In order to purify the remaining sludge, it must be done sequentially, otherwise the sludge effluent will be of poor quality after purification.
6- It has a long start phase.
anoxic system process
Usually, anoxic system processes are used to remove nitrogen from wastewater. Nitrogen is converted into nitrate during the first step during the denitrogenization process. Therefore, with this process, nitrated water is exposed to the environment. The presence of microorganisms in this process causes them to use nitrate as an electron acceptor without the need for oxygen, which in this way provides their necessary oxygen. and then nitrogen is released in the form of N2 gas. This process can be done for sulfates as well, which will eventually release hydrogen sulfide.
Anoxic attached growth reactors
This type of reactor is in the form of a submerged pond inside which filters are used to purify the process. The way this process works is that the wastewater reaches the bottom of the filters and combines with the carbon source. Of course, another source can be used as carbon, which is the purified sludge, even methanol can be used instead.
reactor system (IFAS)
It can be said that the reactor system (IFAS) is a completely new and advanced technology. The IFAS reactor system unit has a combination of two units that include: Activated sludge and fixed bed method.
These two units were created to use the advantages of both methods. The fixed bed process Composite wastewater treatment package It has excellent resistance and stability, and on the other hand, the activated sludge process has been used for biological treatment for a long time. Therefore, if you combine both of them and use them in one unit.
Advantages of using the reactor system (IFAS)
1- Combining the two methods of fixed biofilm and activated sludge makes the sludge to be kept for a longer period of time, which will increase the ratio of nitrate to the simple growth system.
2- It increases the stability of the process.
3- Faster nitrification of the system due to the presence of a large mass of nitrifier in the fixed bed.
4- Less sludge is produced.
معایب استفاده از سیستم راکتور(IFAS)
1- High construction costs
2- Preparing the spare parts that are needed in this system will be more difficult than the other methods
3- A lot of energy is needed. such as aeration
4- It requires an expert and specialized knowledge.
Static settling unit
As usual, in all treatment plants, such as the composite wastewater treatment package, a tank is used to settle the solids in the wastewater and suspended particles. The work of these tanks actually creates stability and stillness necessary for coagulation of solids. At this stage of the process, before the wastewater enters the tank, chemicals are added to it to make it easier to coagulation. One of the features of these tanks that distinguishes it from the others is that after the completion of the purification process, it collects the sludge resulting from the process in a timed and automatic manner.
Microorganisms are found in the waters of lakes, rivers, and even underground waters, on the other hand, they are not harmful to human health at all, but in some cases they may cause disease in humans, which are called pathogens. They are water, they grow and multiply very easily, and they may enter the human body through drinking water, which will cause disease. Therefore, to prevent pathogens in drinking water, they use different methods to disinfect and deactivate these pathogens. Along with the methods used for water purification, such as sedimentation, coagulation and purification, chlorination is also used, which makes drinking water safe. This method has been common since a century ago and is still used today. In the calcification unit, materials such as calcium hypochlorite and sodium hypochlorite are used for the composite wastewater treatment package.
Prefabricated composite sewage treatment package
Advanced techniques and technology are used in prefabricated composite wastewater treatment packages that are used to treat non-concentrated wastewaters. The prefabricated composite sewage treatment package can be used not only for sewage treatment, but also in agriculture. For example, if urban sewage treatment plants are not available to you, you can use the composite sewage treatment package for your operation.
