United States Soft Water Salt 40 Lbs The Perfect Choice for Water Treatment

Product Description:

Soft water salts used in medical hemodialysis systems are mainly made from raw materials such as sea salt, lake salt, mine salt, and rock salt. The following are their grade differences and their impact on product quality and application areas:

Difference in raw material grades

sea salt

Ordinary grade: obtained by direct evaporation and crystallization of seawater, without further refining, may contain a large amount of impurities such as sediment, seaweed, etc. The sodium chloride content is usually around 90% -95%.

Refined grade: After multiple processes such as impurity removal, evaporation, and crystallization, the impurity content is significantly reduced, and the sodium chloride content can reach 97% -99%. The appearance is white and the particles are uniform.

lake salt

Beginner level: Directly extracted from salt lakes, after simple drying and screening, it will contain a certain amount of impurities such as calcium, magnesium, and other minerals, with a sodium chloride content of approximately 92% -96%.

Advanced: After deep processing, most impurities are removed through processes such as dissolution, precipitation, filtration, and evaporation. The sodium chloride content can reach 98% -99.5%, and the product quality is relatively stable.

Well mineral salt and rock salt

Industrial grade: After mining, basic crushing, screening and other treatments are carried out for general industrial use, which may contain small amounts of insoluble impurities and other salts. The sodium chloride content is generally between 95% and 98%.

Food grade/pharmaceutical grade: Through advanced vacuum salt production technology and multiple purification and impurity removal processes, the sodium chloride content is usually above 99%, even up to 99.9%, with extremely low impurity content, meeting strict food safety and medical hygiene standards.

The impact on the quality of finished products

Purity aspect

Soft water salts made from high-grade raw materials have higher purity, such as pharmaceutical grade mine salt or rock salt, with very few impurities, which can effectively avoid problems such as sedimentation and blockage in the hemodialysis system.

The purity of soft water salt produced from low-grade raw materials is relatively low, and it may contain more impurity ions such as calcium, magnesium, and iron, which can affect the effectiveness of soft water and may also cause damage to dialysis equipment.

Solubility performance

The soft water salt made from refined sea salt, high-grade lake salt, and food/pharmaceutical grade well and rock salt has a regular crystal structure, moderate dissolution rate, and uniform dissolution, which can ensure stable saline concentration and provide stable softened water for the hemodialysis system.

Soft water salts made from ordinary grade sea salt, primary lake salt, etc. may have problems such as too fast or too slow dissolution rate, incomplete dissolution, and easy agglomeration, which can affect the normal operation of the soft water system.

Impurity content

The impurities in the soft water salt produced from high-grade raw materials are extremely low, and the heavy metal content is strictly controlled within a safe range, which will not cause secondary pollution to the dialysis water and ensure the safety of dialysis patients.

There are many impurities in low-grade raw materials, which may contain harmful heavy metals such as lead, arsenic, mercury, etc., and can enter the dialysis system with softened water, posing a potential threat to the health of patients.

The impact on the application field

Medical hemodialysis system

Soft water salts made from food grade or pharmaceutical grade well and rock salts are generally used, with a requirement of sodium chloride content ≥ 99.5%, insoluble matter ≤ 0.2%, and moisture ≤ 0.5%.

How can we improve salt softener purity and reduce impurities ?

Optimize raw material selection

Selected mineral sources: For those using well salt and rock salt as raw materials, in-depth investigation of mineral sources is conducted, and mineral layers with high sodium chloride content and low impurity content are selected for mining. For sea salt, choose areas with less pollution and good water quality for sun drying operations.

Strict screening: Strictly screen and inspect the purchased raw materials to remove obvious impurities such as stones, mud, etc.

Improve production process

Dissolution precipitation filtration: In the production process, multi-stage dissolution, precipitation, and filtration processes are used. By adding appropriate precipitants, impurities such as calcium, magnesium, and iron ions are formed into precipitates, which are then removed by high-precision filtration equipment such as ceramic membrane filters, ultrafiltration membrane filters, etc.

Ion exchange: Using ion exchange resin to further remove trace impurity ions from water and improve the purity of soft water salts.

Evaporative crystallization control: During the process of evaporative crystallization, precise control of parameters such as temperature, pressure, and evaporation rate is carried out to ensure uniform growth of sodium chloride crystals and reduce the inclusion and entrainment of impurities. By using vacuum evaporation technology, the evaporation temperature can be reduced, the decomposition and volatilization of impurities can be minimized, and the product quality can be improved.

Strengthen quality inspection

Advanced testing equipment: Equipped with advanced testing equipment such as atomic absorption spectrometer, inductively coupled plasma mass spectrometer, etc., real-time monitoring of raw materials, intermediate products, and finished products is carried out to ensure that product quality meets standards.

Strict quality standards: Establish strict internal quality standards for the enterprise, strictly control indicators such as impurity content and purity, and ensure stable product quality through multiple testing processes for each batch of products.
