The global water treatment chemicals market was valued at USD 31.14 billion in 2022. It is projected to reach USD 40.63 billion by 2031, growing at a CAGR of 3% during the forecast period (2023-2031). Any procedure that enhances water quality to make it suitable for specific end-users is called water treatment. The final use could be for drinking, irrigation, maintaining river flow, water enjoyment, or a variety of other things, including being securely disposed of back into the environment. In order to make the water suitable for the intended end use, water treatment involves removing pollutants and unwanted components or reducing their concentration. Human health depends on this procedure, which also enables drinking and irrigation use benefits.

A crucial element in daily life is access to clean and safe water. Although water can dissolve almost anything, some materials are insoluble in it. These inorganic particles, such as clay, fine sand, dust, and rust, contribute to cloudiness by increasing the concentration of total suspended solids (TSS). The methods used to treat water to lower total dissolved solids (TSS) to levels acceptable to end-users vary with geography, application, and TSS level.

Segmental Analysis

The global water treatment chemicals market is segmented by type and end-user industry.

By Type Analysis

Based on type, the global market is bifurcated into coagulants, pH adjusters and softeners, flocculants, biocides and disinfectants, scale inhibitors and dispersants, corrosion inhibitors, and others.

The corrosion inhibitors segment is the highest contributor to the market and is expected to grow at a CAGR of 5.60% during the forecast period. Corrosion inhibitors are used to turn metal into soluble molecules during water treatment. It reacts with metallic surfaces, creating a layer that shields the surface. Passivity inhibitors (passivation), cathodic and anodic inhibitors, organic and inorganic inhibitors, precipitation-inducing inhibitors, and volatile corrosion inhibitors (VCI) are the five corrosion inhibitors utilized for water treatment. Additionally, these inhibitors are included in chemicals to decrease the chance of corrosion and increase service lifespan. Further, it enhances factory efficiency and lowers the likelihood of equipment failure. Chromates, molybdates, zinc, silicates, and phosphates are corrosion inhibitors used to treat water.

Increased usage of organic, inorganic, or a combination of both coagulants in water treatment to remove suspended solids from water is anticipated to drive market expansion. Aluminum-based and iron-based metal coagulants are the two most often utilized types. Aluminum sulfate, aluminum chloride, and sodium aluminate are coagulants based on aluminum. Ferric sulfate, ferrous sulfate, ferric chloride, and ferric chloride sulfate are the primary ingredients of iron-based coagulants. It is anticipated that there will be a rise in demand for organic coagulants during the forecast period to help reduce sludge production.

The pH scale measures the activity of free hydrogen in water. In order to separate dissolved waste from water during the treatment process, pH adjustment is a crucial step in wastewater treatment systems. The only chemicals examined to estimate the pH adjuster and softener market size are sodium hydroxide and lime. Alkaline water's pH is decreased by adding lime, but acidic water is neutralized by adding sodium hydroxides, which raises the pH without affecting the water's hardness. In order to prevent corrosion on equipment, these chemicals are placed directly into wells.

The use of flocculants, which are varying-weight anionic, non-ionic, and cationic polymers that improve the effectiveness of settling, clarifying, filtering, and centrifugation processes, is expected to raise demand for flocculants for water treatment in the years to come. Flocculation gathers particles into masses to filter or settle out of solutions. The practice of removing suspended particles from home and industrial wastewater is prevalent. Mineral flocculants, natural flocculants, and synthetic flocculants are the three main groups of flocculants. Kemira Oyj and BASF SE are the two leading companies producing flocculants for water treatment.

Chemicals and microorganisms, known as biocides and disinfectants, are used to kill or control hazardous organisms through chemical or biological means. Both industrial and treated water are treated with biocides. Biocides can be categorized into two groups based on how they are used: oxidizing agents (such as chlorine, chlorine dioxide, chloroisocyanurates, hypochlorite, and ozone) and non-oxidizing agents (acrolein, amines, chlorinated phenolic, copper salts, organo-Sulphur compounds, and quaternary ammonium salts). There are two methods of disinfection: chemical disinfection and physical disinfection. Chlorine, chlorine dioxide, hypochlorite, and bromine chloride are the most widely used chemical disinfectants.

Scale inhibitors are negatively charged, surface-active polymers used in both boiling and cooling water systems to treat water. In the oil and gas industry's production, stimulation, and transport processes, scale inhibitors are used to stop the deposition or formation of scale. Scale inhibitors frequently use phosphate esters, phosphoric acid, and low molecular weight polyacrylic acid solutions. Dispersants lessen water hardness and prevent the growth of scale. They also modify and buffer the water that is circulated.

By End-User Industry Analysis

Based on the end-user industry, the global market is bifurcated into industrial, municipal, and others.

The industrial segment owns the highest market share and is expected to grow at a CAGR of 5.25% during the forecast period. In order to maximize diverse water-based industrial processes like heating, refrigeration, rinsing, refining, and cleaning, industrial water treatment is crucial. Scaling, microbial operation, corrosion, and residual water discharge are every industry's four main problem areas. Water treatment in manufacturing ensures the efficient operation of industrial processes and reduces operational expenses. Enterprises must process pre-use raw or untreated water to meet quality standards and process requirements.

Collection, screening, chemical addition, coagulation and flocculation, sedimentation and clarifying, filtration, disinfection, storage, and distribution are some of the processes in the municipal water treatment process. Treatment of drinking water, wastewater, and other types of water, like pool and bottled water, are all included in municipal and other water treatment. Pressure on the water supplies available to meet the overall demand has increased due to increased industrialization, fast urbanization, and a continual drop in water availability per person. The growing issue of water scarcity could be addressed by conserving surface and groundwater resources. Additionally, preventing the degradation of water quality will be an essential step in the direction of water management and conservation strategy.
