Know 9 chemicals that are used in Industrial Water Treatment
Polyaluminum Chloride (PAC)
Polyaluminum chloride, also known as PAC, is one of the most effective water treatment chemicals available today. Compared with other water treatment chemicals, it has a high coagulation efficiency, the widest pH and temperature application range, so it is widely used in drinking water and wastewater treatment.
PAC comes in a variety of colors. The white PAC, with the highest price, is mainly used in special fields such as daily use chemicals; Light yellow is more high-end, often used for drinking water treatment; The yellow powder PAC is used in industrial water treatment.
Aluminium Chlorohydrate (ACH)
Aluminium chlorohydrate is an inorganic polymer flocculant, similar in nature to PAC, with longer shelf life but higher cost, which is used in the special needs for flocculation treatment of water.
Aluminum Sulfate
The chemical formula of aluminum sulfate is Al2(SO4)3, which is mainly used for the flocculation and purification of water. As a coagulant, aluminum sulfate can condense suspended impurities into larger particles, making it easier to settle and filter. This process is called coagulation and flocculation.
At the same time, aluminum sulfate can also be used in the wastewater treatment of paper making, printing and dyeing, leather and other industries.
Polyacrylamide (PAM)
The chemical formula of PAM is (C3H5NO)n, which is divided into anionic, cationic and non-ionic types. PAM is a versatile polymer that adapts to a wide variety of water quality.
- PAM can be used as a flocculant to treat various industrial wastewater and municipal sewage.
- In the paper industry, PAM can be used as a paper retention agent and strengthening agent.
- In agriculture, PAM can be used as a soil conditioner to retain soil moisture and promote plant growth.
- In the petroleum field, PAM can be used as a viscosifier to enhance oil recovery.
For more details, please refer to: Polyacrylamide (PAM) and Oilfield Exploitation
- PAM can be used as dewatering agent, playing an important role in sludge dewatering.
PDADMAC
PDADMAC, a strong cationic polymer used in water treatment as a flocculant, fungicide, and decolorizer to effectively remove suspended matter, organic matter, and microorganisms from water.
- PDADMAC can be used as a flocculant for water treatment to effectively remove suspended particles in water.
- Used as mud stabilizer in oil extraction to improve drilling efficiency and reduce costs.
- In the paper making process, PAM can be used as a fortifying agent to increase the dry and wet strength of paper.
- Used as an antistatic agent and softener in the personal care industry.
Polyamine (PA)
Polyamine, also PA, is colorless to light yellow liquid, with good water solubility and chlorine resistance, non-toxic and tasteless. Like PDADMAC, PA also plays an important role in water treatment, oil extraction, paper making, etc.
Ferric Chloride
Ferric chloride, in the form of black brown crystals or flakes, easily soluble in the water and has a strong water absorption.
Ferric chloride is an inorganic flocculant with strong oxidation ability, which can remove H2S and other reducing substances in water, so it is suitable for treating high concentration organic polluted water.
Antifoam
Antifoam, also defoamer, can be used to remove foam from water treatment processes to prevent foam from adversely affecting equipment and processes.
There are many kinds of defoamer, such as silicone defoamer and polyether defoamer.
- Silicone defoamer: White emulsion composed of silicone oil, emulsifier, stabilizer and dispersant. The defoamer is widely used in water treatment, coating field, textile industry, food processing and so on.
- Polyether defoamer: A highly effective non-silicon-based defoamer designed for a wide range of industrial applications. The defoamer is particularly suitable for water systems and provides excellent performance even under the most demanding conditions.
Decoloring Agent
Decoloring agent is mainly used to remove pigments and colored substances in industrial wastewater, so that the wastewater can meet the discharge standards or reuse requirements.
There are three kinds of decolorizing agents: oxidation decolorizing agent, adsorption decolorizing agent and flocculating decolorizing agent. Due to the limitations of the first two, flocculant decolorizers are the mainstream products for decolorizing chemicals.
How Industrial Water Treatment Chemicals Work
Industrial water treatment is a complex process that involves several steps to ensure the quality and purity of water for various applications. Here's a breakdown of how chemical treatments contribute to this process:
Clarification.
- Coagulation: Coagulant chemicals, such as polyaluminum chloride or ferric chloride, are added to the water. These chemicals neutralize the charges on suspended particles, causing them to clump together.
- Flocculation: Flocculating agents, like polyacrylamide (PAM), are added to promote the aggregation of these clumps into larger, heavier particles called flocs.
- Sedimentation: The larger flocs settle to the bottom of a sedimentation tank due to gravity, forming a sludge layer.
Disinfection.
- Chlorination: Chlorine-based chemicals, such as Sodium Dichloroisocyanurate (SDIC) and Trichloroisocyanuric Acid (TCCA), are added to kill bacteria and other microorganisms.
- UV Disinfection: Ultraviolet light is used to inactivate microorganisms by damaging their DNA.
- Ozone Disinfection: Ozone gas is a powerful oxidant that can kill microorganisms and oxidize organic matter.
Although UV and Ozone disinfection methods are also used, the chlorine disinfection is still one of the most important disinfection methods.
Lime Softening.
Lime Addition: Lime (calcium hydroxide) is added to increase the pH of the water, which causes calcium and magnesium ions, contributing to water hardness, to precipitate out of solution as insoluble solids.
Ion Exchange (IX).
Ion Exchange Resin: Water is passed through a bed of ion exchange resin. The resin exchanges sodium ions for calcium and magnesium ions, reducing water hardness.
Membrane Filtration.
Microfiltration (MF): Removes large particles, such as bacteria and algae.
Ultrafiltration (UF): Removes smaller particles, such as viruses and colloids.
Nanofiltration (NF): Removes dissolved salts and organic molecules.
Key Points:
- The choice of chemical treatment depends on the specific water quality issues and the desired end-use of the water.
- Effective water treatment requires careful monitoring and control of chemical dosing, pH, and other parameters.
- Proper disposal of sludge and other waste generated during water treatment is essential to protect the environment.
