Cooling tower appliction

One. Issues related to circulating water:

During the operation of the industrial circulating cooling water system, due to wind loss, water evaporation and other conditions, the circulating water is continuously concentrated, resulting in salt exceeding the standard, impurities or cations increase, and the pH value changes significantly, resulting in deterioration of water quality.

The temperature, PH value and nutrients of the circulating water are beneficial to the reproduction of microorganisms. The extra sunlight on the cooling tower is an ideal place for algae growth.

In response to these circumstances, it is inevitable to treat the circulating water.

TWO. Traditional coping style:

In order to solve these problems, multiple protection methods and treatment agents are generally used at the same time in the operation of the cooling cycle system, such as: non-oxidizing bactericide, oxidizing bactericide, algaecide, anti-corrosion coating, corrosion and scale inhibitor Corrosion inhibitors, etc.

THREE. Defects of the traditional way:

1. A large amount of financial and human resources:
Adding multiple medicaments at the same time will cause a lot of financial and manpower expenditures, thereby greatly increasing the operating cost of the system.

2. Single effect and strong negative effect:
The role of each agent is often singular, but it brings new problems while solving a problem. For example, the anti-corrosion coating will reduce the heat conduction of the system while preventing corrosion; the chlorine bactericide will aggravate the chloride ion corrosion while sterilizing.

3. Incompatibility between multiple medicaments:
The incompatibility between multiple chemical agents can cause the overall effectiveness of the system to decrease. Experience has shown that the more types of agents added to the circulating water system, the worse the system's operation.

4. Environmental hazards:
Most of the commonly used circulating water treatment chemicals currently contain harmful ingredients. For example, chlorine-containing bactericides can cause chloride (AOX) to exceed the standard.
In the face of the above situation, the silver nano-aqueous nano-aqueous solution, while achieving high-efficiency sterilization, can solve various problems of the cooling circulating water system, and is the most ideal comprehensive treatment agent for the cooling cycle/cooling tower.

FOUR. AGNPCLEAN Nano-silver Aqueous Solution:

Silver nano-silver-silver ion aqueous solution solution, as a fungicide, is particularly suitable for water treatment and can effectively kill bacteria, fungi, viruses and algae. The bactericidal effect of silver ions is based on the monovalent silver ions through covalent bonds and coordination bonds to firmly bind to bacterial proteins, thereby inactivating or precipitating bacteria, positively charged silver ion free radicals can directly act on the cell walls of microorganisms. Oxygen chemically reacts with desaturase molecules in the cell wall and destroys the cell wall.

Advantages of AGNPCLEAN NanoSilver Aqueous Solution in Cooling Circulation System:

Broad antibacteric:

A broad-spectrum product that does not produce microbial infectivity and can effectively target all types of microbes:

① Pathogens (Gram positive / negative, Pseudomonas aeruginosa, Legionella, Escherichia coli, etc.)

②Biofilm formed by bacteria (mucus forming bacteria, mycelium and sulfate-reducing bacteria)

③Virus

④Yeast

⑤Fungi

Eco-environmental:

Silver ions can be completely degraded without causing environmental pollution.  

It does not contain any substances that can produce AOX, so it will not cause an increase in AOX content. After using sodium hypochlorite, the AOX content of the main cooling water increased from 23g / L to 151g / L.

Improve heat transfer coefficient:

Clean the surface of the heat exchanger to the best extent to prevent surface deposition and improve the heat transfer coefficient (optimize the K value). So that you can achieve:

① Can conduct more heat.

② Reduce the load of the cooling fan (thereby reducing energy consumption).

Excellent cleaning effect:

Reduce the number of microorganisms and biological deposition,

Thereby greatly reducing the cleaning workload. Only lime dust deposits need to be cleaned. In the absence of biofilm deposition, it is also easier to clean lime deposits and reduce system corrosion.

Other Characteristic :

① Lower installation and maintenance cost

② Wide temperature range: can be applied in the whole temperature range of 0℃-95℃

③ Do not change the PH value of water

④ Applied in the environment of PH value 2-9, the effect is best in the environment of PH = 7

⑤ No corrosiveness, no need to take additional measures to reduce corrosion

⑥ Odorless and tasteless, without any form of stimulation at the specified dilution concentration

Application dose:

① Impact dosing of new and clean devices :

April-September (spring and summer): about 100ppb

October-March (autumn and winter): about 50-100ppb

② Shock dosing with obvious biofilm and poorly maintained facilities

April-September (spring and summer): about 1000ppb

October-March (autumn and winter): about 500-1000ppb

③ Continuous dosing:

With reference to various factors of water, according to the amount of water in the circle, the amount of addition varies between 1ppb~ 30ppb
