Ion Exchanger

Industrial boiler water (including steam boiler and hot water boiler feedwater): Its core function is to prevent boiler scaling, extend boiler service life, improve equipment thermal efficiency, and ensure stable and safe operation of the boiler. Cooling circulating water (including air conditioning, direct combustion engine, and cooling tower makeup water): mainly used to reduce pipeline scaling, lower equipment operating energy consumption, and avoid pipeline blockage affecting the normal operation of the circulation system. Production process water (suitable for industries such as chemical, pharmaceutical, printing and dyeing, brewing, etc.): can ensure stable water quality required for the process, prevent corrosion and blockage of production equipment, ensure smooth production process and meet product quality standards. Domestic water (covering hotels, restaurants, office buildings, apartments, homes, etc.): The focus is on preventing scaling of hot water equipment, improving daily bathing experience, and extending the service life of domestic water equipment. Reverse osmosis pretreatment (RO system pre softening): The core purpose is to protect the reverse osmosis membrane, prevent membrane surface scaling, extend membrane service life, and ensure efficient and stable operation of the reverse osmosis system.

Product Introduction

The ion exchange resin hardness removal system uses sodium type cation exchange resin to replace scaling ions such as calcium (Ca ² ⁺) and magnesium (Mg ² ⁺) in water with sodium ions (Na ⁺), thereby achieving water quality softening. It is mainly used for boiler feedwater, industrial circulating water, and domestic water treatment.

When the raw water flows through the resin tank, Na ⁺ on the resin exchanges with Ca ² ⁺ and Mg ² ⁺ in the water, and Ca ² ⁺ and Mg ² ⁺ are adsorbed onto the resin. Na ⁺ enters the water, and the effluent is softened water.

Equipment composition: resin tank (for storing resin)+salt tank (for storing recycled salt)+control valve (for automatically controlling the operation process)+pipeline valve.

Regeneration process: When the resin is saturated with adsorption, the system automatically flushes the resin layer with salt water, and Na ⁺ replaces Ca ² ⁺ and Mg ² ⁺ to be discharged, restoring the resin's softening ability.

Technical Advantage
Equipment protection and energy conservation and consumption reduction
Eliminate calcium and magnesium ion scaling, extend the service life of boilers, heat exchangers, and other equipment, while improving heating efficiency and saving energy by 8% -12%.
Fully automatic and stable operation
Adopting fully automatic control valves to achieve full automation of operation and regeneration, without the need for manual supervision; The hardness of the effluent has steadily decreased to below 50ppm, meeting the standards for industrial and domestic water use.
Low operation and maintenance costs
Regeneration only consumes industrial salt (NaCl), with no complex chemicals, simple maintenance, and economical operating costs.
Long service life of resin
The resin can be recycled and reused, with a lifespan of over 10 years under normal maintenance conditions, and has a high comprehensive cost-effectiveness.
Equipment Selection

1. Determine the operating mode

The selection of equipment operation mode is mainly based on whether interruption of water usage is allowed:

Intermittent water supply: It is recommended to use a single valve and single tank configuration. In this mode, the device will stop producing water during regeneration, which is suitable for intermittent water use scenarios that can accept short-term water maintenance.

Continuous water supply required: It is recommended to use a one in use and one backup or dual tank configuration. When one set of tanks is regenerated, another set of tanks can continue to operate, achieving 24-hour uninterrupted water supply.

2. Core parameter calculation

The three core parameters and their acquisition methods for equipment selection are as follows:

Hourly processing capacity: The unit is tons per hour (t/h), which is usually provided directly by the user and serves as the basis for determining equipment specifications.

Raw water hardness: The unit is milligrams per liter (mg/L), which needs to be obtained through water quality testing. The higher the hardness of the raw water, the greater the amount of resin required to remove these ions.

Periodic water production: The unit is cubic meters (m ³), which determines the regeneration frequency of the equipment. The calculation formula is: the total amount of resin multiplied by the resin working exchange capacity, and then divided by the hardness of the raw water.
