There are two types of transfer when bacteria are used to purify water, and aerobic transfer is one of them. Aerobic transfer is the conversion of pollutants in water by oxygen-dependent bacteria. Aerobic bacteria require oxygen for different types of chemical transformations. Aerobic bacteria convert the compounds when there is enough oxygen. In general, aerobic bacteria convert pollutants into carbon dioxide and water.

There are two types of transfer when bacteria are used to purify water, and anaerobic transfer is one of them. The anaerobic transfer is the conversion of pollutants in water by oxygen-independent bacteria.

Anaerobic bacteria use other types of substances to carry out chemical transformations. Anaerobic bacteria perform the transformation when the water is low in oxygen. During its conversion, not only carbon dioxide and water are produced, but also methane gas.

The ultraviolet water filter is a compact, precise, energy-saving, and environmentally friendly disinfection system, which is an effective and safe way to eliminate harmful bacteria in water. In the ultraviolet water disinfection technology, ultraviolet light with a wavelength of 253.7 nanometers is used to disinfect bacteria, viruses, molds, algae, and other microorganisms that multiply and grow in large numbers. UV disinfection technology destroys the DNA of microorganisms, rendering them dead and unable to grow further.

Activated carbon after processing has pores with small shapes and small areas, which increases its surface area in use. Activated carbon filters can adsorb and filter chemicals very well, and effectively remove chlorine, sediment and other particles, volatile organic compounds and odors in the water.

Bacteria and microorganisms in water can also be removed by disinfection. It can be done by adding certain substances such as fungicides to remove bacteria. UV light is a more environmentally friendly way of disinfecting.

Fertilizers such as phosphates in water are chemically reacted by adding another substance (iron), which turns into solid precipitates, which are then removed by filtration.

Settling

Some pollutants, such as oil, can be settled in a settling tank prior to the start of the purifying process. Once they have descended to the tank’s bottom, they are very simple to remove.

Removal of dangerous microorganisms

It is frequently necessary to remove microbes from polluted water. After that, the water is typically chlorinated to sterilize it.

Removal of dissolved solids

Microorganisms can be beneficial for the methods used to purify water in addition to being a hazard to it. They have the capacity to transform harmful pollutants into harmless substances.

Physical/ chemical techniques

When microbial treatment is not available, we usually use different physical or chemical treatment technologies for water treatment. Chemical treatment involves the addition of chemicals that change the material structure of pollutants for better removal. Physical treatment is directly related to the purification process, and filtration is one of the most common methods.

Industrial water treatment is the method, technique, or mechanism utilized to prepare water (incoming feed water) for initial usage before it is employed in manufacturing or commercial operations.

Industrial wastewater treatment refers to the procedures, gear, or methods used to clean up water that has been tainted by industrial or commercial operations before it is returned to the environment or put to use again.

Industrial businesses and manufacturing facilities frequently need to treat spent water or wastewater before discharging it in order to stay in compliance with discharge regimes that protect the environment.

Industrial wastewater treatment and industrial water treatment technologies can use chemical treatment in addition to multi-stage water filtration systems.

Generally speaking, the two ways are chemical water treatment and physical industrial water treatment equipment. Chemical treatment is generally used before physical equipment water treatment. The choice of boiler feed water treatment method largely depends on the water quality type of raw water and the industrial pressure of the boiler itself.

Calcium carbonate scaling is relatively common in low-pressure boilers. Demineralized water (with the highest purity) should only be used in high-pressure boilers, as water of lower purity can lead to deposits or corrosion in the boiler equipment. The water quality of boiler feed water can be produced and treated by filtration, softening, reverse osmosis process, and other treatment methods, especially reverse osmosis and softener can also reduce the chemicals needed to treat boiler feed water.

Soften water can only meet the needs of some low-pressure boilers, but for most boiler-feed water treatment, soften water treatment alone is far from enough. The softener can only remove the calcium and magnesium minerals deposited by the scale, but cannot remove other sediments and minerals. A reverse osmosis filtration system solves this very well, filtering out all the chemicals and providing high-quality water to the boiler.

Reverse osmosis is a water treatment technology that uses semi-permeable membranes to remove most pollutants and impurities from water. The membrane allows only water molecules to pass through, while most dissolved solids and pollutants are blocked. The technology removes up to 99% of impurities and contaminants.

The shortest answer is no. Superior industrial reverse osmosis systems remove solid particles from the water up to 0.001 microns, blocking most contaminants (95% and above). During the operation of an industrial reverse osmosis system, approximately 50% to 75% of the filtered feed water can be recovered for recovery.

Reverse osmosis and nanofiltration are similar in appearance and function. Both systems force water through membrane filters, removing unwanted contaminants from the water.

The main difference between the two is that nanofiltration does not absolutely block dissolved minerals but allows 15% of dissolved minerals to exist in the water. Reverse osmosis will block 90% or more of the same minerals.

Nanofiltration is mainly used to purify drinking water. Since minerals can cause damage to industrial systems such as boilers, reverse osmosis is still the preferred filtration method for industrial purposes.

What you’re aiming to remove will have a big impact on the kind of filtration system you choose. For substances such as chlorine, you only need to use activated carbon filters. For water with too much hardness, the industrial water softening system is needed to deal with.

For iron-removing or suspended sediments, the best way to deal with them is filtering through oxidation and depth or multimedia filters. For bacteria and viruses in water, reverse osmosis, sub-micron filtration, and ultraviolet sterilization are good choices.

Water filters are physical barriers that can block or retain impurities and solid particles in water or wastewater, and some even prevent bacteria from passing through. In general, the size of the gaps in the filter barrier or membrane will determine how quickly water flows. Brother Filtration has a variety of industrial filters to choose from, considering the most ideal solution in combination with different dimensions such as water quality and industrial needs.

Gravity water filter is to use gravity to promote water through the sand or smoke-free coal filter bed to a lower level. Pressure water filters generally use glass fiber or steel pressure vessels, forcing the water to go down through the filter bed.

Nowadays a single water softener or filtration system is not enough to meet the needs of most industries. The use of purified water will be more gentle for industrial equipment, reducing corrosion and maintenance of industrial systems. Especially the cooling tower water system is in great need of durable piping in order to avoid the failure of the whole system.
