Wastewater Treatment Chemicals

Selection And Use Of Wastewater Treatment Chemicals

The specific wastewater treatment chemicals that are used will vary depending on the type of wastewater being treated, the pollutants that need to be removed, and the desired results. It is important to carefully select the right chemicals and to use them in the correct dosage to achieve the best results.

Overdosing chemicals can be costly and can also lead to environmental problems. For example, overdosing chlorine can kill fish and other aquatic life. Underdosing chemicals can reduce the effectiveness of the wastewater treatment process and can lead to the discharge of pollutants into the environment.

It is important to consult with a qualified wastewater treatment professional to select the right wastewater treatment chemicals for your needs and to ensure that they are used in the correct dosage.

There are a variety of wastewater treatment chemicals available, each with its own specific purpose. Some of the most common wastewater treatment chemicals include:

  • Coagulants and flocculants: Coagulants and flocculants are chemicals that are used to remove suspended solids from wastewater. Coagulants neutralize the electrical charge on suspended solids, causing them to clump together. Flocculants bind to the clumps of solids, making them larger and heavier. This makes it easier to remove the solids from the water using settling or filtration.
  • Disinfectants: Disinfectants are chemicals that are used to kill harmful bacteria and other microorganisms in wastewater. Common disinfectants used in wastewater treatment include chlorine, ozone, and ultraviolet light.
  • pH adjusters: pH adjusters are used to control the pH of wastewater. Maintaining a neutral pH is important for the effective operation of many wastewater treatment processes.
  • Nutrient removal chemicals: Nutrient removal chemicals are used to remove excess nutrients, such as nitrogen and phosphorus, from wastewater. These nutrients can cause algae blooms and other problems in water bodies. Common nutrient removal chemicals include alum, ferric chloride, and lime.
  • Heavy metal removal chemicals: Heavy metal removal chemicals are used to remove heavy metals, such as lead, cadmium, and mercury, from wastewater. These metals can be toxic to aquatic life and humans. Common heavy metal removal chemicals include sulfide, lime, and activated carbon.

Benefits Of Using Wastewater Treatment Chemicals

There are a number of benefits to using wastewater treatment chemicals, including:

  • Improved wastewater quality: Wastewater treatment chemicals can help to improve the quality of wastewater by removing pollutants, such as suspended solids, harmful bacteria, excess nutrients, and heavy metals. This can help to protect public health and the environment.
  • Reduced environmental impact: By removing pollutants from wastewater, wastewater treatment chemicals can help to reduce the environmental impact of wastewater discharges. This can help to protect water quality and aquatic life.
  • Compliance with regulations: Many wastewater treatment facilities are required to comply with strict regulations on the quality of their effluent. Wastewater treatment chemicals can help facilities to comply with these regulations and to avoid costly fines and penalties.

Wastewater treatment chemicals are an essential part of the wastewater treatment process. They help to remove pollutants from wastewater and make it safe for discharge into the environment. There are a variety of wastewater treatment chemicals available, each with its own specific purpose. It is important to carefully select the right chemicals and to use them in the correct dosage to achieve the best results.

Chemicals

Biological Augmentation

Biological Augmentation for Wastewater treatment refers to the use of select micro-organisms to augment the wastewater and facilitate microbial digestion of compounds.

Coagulants

Coagulants for wastewater treatment play a vital role in the process, allowing for solids removal and dewatering, water clarification, lime softening, and sludge thickening. With the help of other specialized chemicals and mechanical filtration methods, coagulants help companies maintain a consistent and reliable source of clean water to support their industrial processes.

Flocculants

High quality dewatering flocculants help to create a reliable and efficient system to ensure you mitigate downtime and maintenance costs. At ChemREADY, we provide chemicals and treatment solutions customized to meet your needs.

NoFoam

To ensure that water systems are well maintained and operate at optimum efficiency, the correct water conditions are essential at all times. This can be achieved using carefully selected antifoams and defoamers.

Sewer & Wastewater Odor Control

In the modern world of wastewater conveyance and treatment, a primary design consideration for most collection and treatment facilities is controlling the odors in a cost effective manner. As the attention paid to odor control has increased, so has the number of odor control technologies that are available in the marketplace.

Phosphorus Removal

The removal of phosphorus (P) from domestic wastewater is primarily to reduce the potential for eutrophication in receiving waters, and is mandated and common in many countries. However, most P-removal technologies have been developed for use at larger wastewater treatment plants that have economies-of-scale, rigorous monitoring, and in-house operating expertise.

pH Adjusters for Water Treatment

A pH adjuster is a chemical used to alter the pH or Potential Hydrogen level. pH (Potential Hydrogen) is the measurement of the activity of the hydrogen ion or how basic or acidic something is. By adding a pH reagent such as an acid you can drive pH downward. By using a caustic or other alkaline substance you can drive pH upward. Typical pH range is 0-14 but actual pH levels can exceed these theoretical limits.
