Remineralization and pH Booster System in Water Treatment

Remineralization and pH boosters are important technologies in water treatment that serve to restore essential minerals and balance the pH of water after going through purification processes such as reverse osmosis (RO) or demineralization. This process is essential because water that has gone through high levels of purification often loses essential minerals and has a low pH, which can lead to corrosiveness and is less than optimal for various applications.

Why are Remineralization and pH Boosters Needed?

Water purification processes such as reverse osmosis are very effective at removing contaminants, but also remove beneficial minerals such as calcium, magnesium and bicarbonate. Water that has been fully purified (demineralized) has some unfavorable characteristics:

Low pH (acidic) which can cause corrosion of pipes and equipment
Lack of essential minerals required for health
Poor taste for consumption
Aggressive nature towards materials it comes in contact with
Electrolyte imbalance that can affect biological processes

Remineralization and pH boosters address these issues by adding back essential minerals and balancing the pH of the water, resulting in water that is more stable, less corrosive, and more suitable for a variety of needs.

How Remineralization and pH Booster Systems Work

Remineralization and pH booster systems use various methods to restore minerals and balance the pH of water. Here are some of the commonly used methods:

1. Calcium Carbonate Media

One of the most common methods is to run water through a medium containing calcium carbonate (CaCO₃), such as limestone, marble, or calcite. When water with a low pH comes into contact with these media, a chemical reaction occurs that dissolves some of the calcium carbonate:

CaCO₃ + H₂CO₃ → Ca(HCO₃)₂

This reaction increases the calcium content in the water while increasing the pH and alkalinity. Media such as Clack Calcite and Imerys Calcite are specifically designed for this purpose.

2. Magnesium and Calcium Mixed Media

To increase the effectiveness of remineralization, some systems use a mixture of media containing magnesium oxide (MgO) and calcium carbonate. Media such as Clack Corosex (magnesium oxide) is often mixed with calcite to provide stronger pH adjustment and add beneficial magnesium to the water.

3. Chemical Injection

For large-scale systems, chemical injection is often used for remineralization and pH adjustment. Commonly used chemicals include:

Sodium bicarbonate (NaHCO₃) to increase alkalinity and pH
Calcium chloride (CaCl₂) to add calcium ions
Magnesium sulfate (MgSO₄) to add magnesium ions
Sodium hydroxide (NaOH) for pH adjustment

Chemical injection systems require precision dosing pumps such as LMI or OBL that can accurately regulate the amount of chemicals added.

4. Remineralization Cartridge

For small-scale systems, remineralization cartridges containing calcite media or other mineral mixtures can be used. These cartridges are easy to install and replace, making them a popular choice for under-sink or point-of-use systems. Products such as HydroPro Mineral Cartridge and Aqualine Remineralization Cartridge are specifically designed for this purpose.

Key Components of Remineralization and pH Booster Systems

A comprehensive remineralization and pH booster system usually consists of the following components:

Mineral contact tank: Contains remineralization media such as calcite or calcite-corosex mixture. This tank can be a Pentair or HydroPro FRP tank designed to withstand the required pressure and flow.
Control valve: Regulates the flow of water through the remineralization media, such as Fleck, Autotrol, or Runxin.
Chemical injection system: For systems that use injection methods, this component includes the chemical tank, dosing pump(LMI, OBL), and controller.
Monitoring system: pH, conductivity, and TDS sensors to monitor the quality of the produced water. Instruments such as Create Instruments or HydroPro Sensors ensure the water parameters are always within the desired ranges.
Post-filter cartridge: To filter out fine particles that may have escaped from the remineralization media, such as the Pentair Pentek or HydroPro Cartridge.

Remineralization and pH Booster System Applications

Remineralization and pH booster technologies are used in a variety of industries and applications, including:

Food and Beverage Industry

Bottled water production
Soft drink and beer manufacturing
Food processing that requires high quality water
Dairy and dairy industry
Ice cream and frozen food production

In these industries, remineralization is important to create a consistent and optimal taste profile. Minerals such as calcium and magnesium contribute to the flavor of the water and can affect the characteristics of the final product.

Pharmaceutical and healthcare industry

Production of water for drug formulation
Laboratories and research facilities
Hospitals and clinics
Medical equipment production

In the pharmaceutical industry, purified water often requires controlled remineralization for certain applications. A balanced pH is also important to prevent corrosion of equipment and pipes.

Manufacturing industry

Semiconductor and electronics production
Automotive industry
Precision equipment manufacturing
Dyeing and textile industries

In manufacturing processes, water with a balanced pH and mineral content can prevent corrosion of equipment, extend machine life, and improve product quality.

Commercial Applications

Hotels and restaurants
Shopping centers
Office buildings
Schools and universities

Commercial facilities use remineralization systems to ensure safe and palatable drinking water, and prevent corrosion of the piping system.

Residential Applications

Household water treatment systems
Under-sink system for drinking water
Whole-house systems to prevent corrosion

In households, remineralization is mainly used after reverse osmosis systems to improve the taste of drinking water and prevent corrosion of pipes and equipment.

Benefits of Remineralization and pH Booster System

Implementation of remineralization and pH booster systems provides various benefits, including:

Technical Benefits

Corrosion prevention: Water with balanced pH and sufficient alkalinity is non-corrosive to pipes, fittings, and equipment, extending the life of the system.
Water stability: Remineralized water is more stable and less reactive, reducing the risk of quality changes during storage or distribution.
Compatibility with other systems: Water that has been pH balanced is more compatible with other treatment systems such as UV disinfection or ozonation.
Reduction of scaling: Controlled remineralization can prevent excessive scale formation on equipment and pipes.

Economical Benefits

Reduced maintenance costs: Preventing corrosion means less repair and replacement of system components.
Improved energy efficiency: Systems free from corrosion and scaling operate more efficiently, saving energy.
Extended equipment life: Equipment that avoids corrosion has a longer service life, reducing replacement costs.
Reduced downtime: Systems operating with balanced water experience fewer interruptions and downtime.

Product Quality Benefits

Improved taste: Remineralized water has a more pleasant and natural taste.
Product consistency: For the food and beverage industry, remineralization ensures quality consistency of the final product.
Added nutrients: Minerals such as calcium and magnesium provide health benefits to consumers.
Improved process quality: For industrial applications, water with a balanced pH and minerals can improve process results.

Remineralization and pH Booster System Selection and Design

Selecting the right remineralization and pH booster system requires consideration of several important factors:

Design Factors

Feed water quality: Characteristics of the water before remineralization, including pH, TDS, and alkalinity.
Water quality targets: Desired water specifications after remineralization, including pH, hardness, and mineral profile.
Flow rate: The volume of water that needs to be processed per unit time.
Available space: Space limitations for system installation.
Budget: Initial investment costs and long-term operating costs.
Maintenance needs: Frequency and complexity of maintenance required.

Operational Considerations

Media consumption: Media such as calcite will deplete over time and need to be replenished.
Backwash requirements: Some remineralization systems require periodic backwash to prevent channeling and media compaction.
Quality monitoring: Monitoring system to ensure consistent water quality.
Chemical availability: For chemical injection systems, the availability of the required chemicals should be considered.
