How to Solve the Problem Caused By Circulating Water

During the operation of the industrial cooling water system, the salt contained in the circulating water due to evaporation, wind damage, etc. breaks through, the ions increase, the pH changes significantly, the water quality deteriorates, and the temperature of the circulating water, pH and nutrients are beneficial. Microbial reproduction.

A cooling tower is an ideal place for plenty of sunlight to grow algae. Proportional control and corrosion control, microbial control, etc., are necessary for circulating water.

The main problem is the circulating water produced during operation.

1. Scale

As the water circulates during the cooling process, the water continuously increases the salt concentration and precipitates above a certain salt solubility. Commonly found are calcium carbonate, calcium phosphate, magnesium, and other pollutants.

The ratio is relatively dense and dense, greatly reducing the heat transfer efficiency, 0.6 mm 20% lower heat transfer coefficient and thicker dirt.

2. Dirt

Dirt is mainly concentrated in the organic matter composed of water, microbial colonies, discharge, sediment, dust, and soft texture. It not only reduces heat transfer efficiency but also reduces the life of equipment under the scale of corrosion.

3. Corrosion

Recycling heat exchange equipment is waterproof and anti-corrosive, mainly due to equipment corrosion defects, sufficient water, oxygen, water, corrosive ions (chloride, Fe2+, Cu2+) and dirt and other mucus secretion. The consequence of the corrosion consequences of micro-organisms is that even heat exchangers, water pipeline equipment are very severely scrapped and uncontrolled for short periods of time.

4. Microbial Slime

Due to a large amount of dissolved oxygen in the circulating water, suitable temperature and nutrient-rich conditions, it is suitable for microbial growth and reproduction.

If it is not controlled, it will quickly lead to the deterioration of water quality. Black, a lot of cooling towers with sticky deposits block the cooling and heat dissipation, equipment corrosion increases.

Therefore, treatment of circulating water is necessary to control the reproduction of microorganisms.

To ensure the operation of long-cycle production equipment, but also to improve the utilization of circulating water.

The use of circulating water treatment technology not only brings significant economic benefits to enterprises but also good social benefits for the society. Circulating water treatment technology is very necessary.

Amino trimethylene phosphonic acid, which is mainly used in industrial water treatment, is a highly effective stabilizer. Has a good chelation, low limit inhibition, lattice distortion, and other effects. Effectively prevent scale salts in water from forming various types of scale.

ATMP acid

ATMP chemical also has a corrosion inhibiting effect and can be used as a chelating agent and a scale inhibitor. It is used in scale inhibitors and corrosion inhibitors in large thermal power plants, recirculating cooling water in refineries, oilfield water injection systems and low-pressure boiler water.

ATMP has good chelation, low restriction inhibition, and lattice distortion. It prevents the formation of scale in the water, especially the formation of calcium carbonate scale.

ATMP acid is chemically stable in water and difficult to hydrolyze. When the concentration in water is high, it has a good inhibition effect.

ATMP is used to circulate cooling water in thermal power plants, refineries, and oilfield refill systems. It can reduce the corrosion and scaling of metal equipment or pipes. ATMP acid is used as a metal ion chelating agent in the textile printing and dyeing industry and as a metal surface treatment agent.
