Water Treatment Industry

Committed to purifying various water sources to meet different water quality standards such as domestic water and industrial water.This industry requires various chemicals to remove impurities, pollutants, etc. from water to ensure water quality safety.

RELATED PRODUCTS

Sodium Bicarbonate

Weakly alkaline, mild and non corrosive, easily decomposed into carbon dioxide when heated.

Industrial wastewater pH adjustment scenario

Specific Scenario

Used for neutralization treatment of acidic wastewater (such as electroplating wastewater, printing and dyeing wastewater).

Product Function

Weak alkalinity can slowly adjust the pH value to neutral, avoiding local alkali problems caused by strong alkalinity, and the reaction is mild, reducing corrosion to equipment.

Industrial wastewater pH neutralization (acidic wastewater treatment)

Applicable Scenarios

Processing acidic wastewater (pH ≤ 5) from industries such as electroplating, printing and dyeing, and chemical engineering, such as electroplating wastewater containing sulfuric acid and hydrochloric acid, and printing and dyeing wastewater containing organic acids.

Application Advantages

Soda ash has a mild alkalinity and minimal pH fluctuations during the adjustment process, which can reduce the problem of heavy metal hydroxide precipitation and encapsulation caused by local alkalinity; And the cost is relatively low, suitable for large-scale wastewater treatment.

Soda Ash Light

Adjusting pH value, softening water quality, and removing heavy metal ions are the basic chemicals for industrial wastewater and municipal sewage treatment.

Soda Ash Dense

Adjusting pH value, softening water quality, and removing heavy metal ions are the basic chemicals for industrial wastewater and municipal sewage treatment.

Applicable Scenarios

Pre treatment of industrial circulating water systems to prevent pipeline scaling; Municipal tap water softening (especially in hard water areas).

Application Differences

Soda Ash Dense is suitable for continuous softening systems due to its coarse particles and slow dissolution (by slowly stirring the reaction in a reaction tank); Soda Ash Light dissolves quickly and is suitable for intermittent softening equipment (such as small circulating water filtration systems).

FAQ

When should one choose Soda Ash(Soda Ash Dense or Soda Ash Light), and when should one choose Sodium Bicarbonate?

Selecting Soda Ash
It is necessary to quickly and significantly increase the pH value (for example, neutralize strongly acidic wastewater, meet the pH requirements for discharge, and promote the precipitation of metal hydroxides (excluding heavy metals)).
We need to use carbonate ions for chemical precipitation softening.
It is necessary to simultaneously increase the pH and total alkalinity, and allow the pH to rise higher.
Choose Sodium Bicarbonate
Need to gently and accurately increase or stabilize pH to avoid excessively high pH.
The main goal is to supplement and maintain alkalinity/buffering capacity, without causing drastic changes in pH.
Dealing with weakly acidic conditions or situations that require buffering.
As a neutralizing agent after dechlorination.
