Wastewater Treatment Chemicals

Selection and Use of Wastewater Treatment Chemicals

Choosing the right wastewater treatment chemicals is essential for effective pollutant removal. The selection depends on the type of wastewater, the pollutants present, and the desired outcomes. Proper dosing is crucial—overdosing can harm the environment, such as chlorine killing aquatic life, while underdosing can reduce treatment effectiveness and allow pollutants to enter the environment.

Consulting a qualified wastewater professional ensures you select the correct chemicals and use them in the right dosage for optimal 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.

Coagulants and Flocculants: Coagulants neutralize the charge on suspended solids, causing them to clump together. Flocculants bind the clumps, making them larger and easier to remove through filtration or settling.
Disinfectants: These chemicals, such as chlorine, ozone, and UV light, kill harmful bacteria and microorganisms in wastewater.
pH Adjusters: pH adjusters control the pH levels in wastewater, ensuring optimal conditions for other treatment processes to operate effectively.
Nutrient Removal Chemicals: Chemicals like alum, ferric chloride, and lime remove excess nutrients like nitrogen and phosphorus, which can lead to algae blooms in water bodies.
Heavy Metal Removal Chemicals: Chemicals such as sulfide, lime, and activated carbon remove toxic metals, including lead, cadmium, and mercury, which are harmful to aquatic life and humans.

Benefits of Using Wastewater Chemicals

Improved Water Quality: Wastewater chemicals remove pollutants such as suspended solids, harmful bacteria, nutrients, and heavy metals, protecting public health and the environment.
Reduced Environmental Impact: Chemicals help minimize the environmental impact of wastewater discharges by effectively removing harmful pollutants.
Regulatory Compliance: Many facilities must adhere to strict effluent quality standards. Using the correct chemicals helps them meet these regulations and avoid fines and penalties.

Using wastewater treatment chemicals is crucial for ensuring safe water discharge into the environment. Each chemical serves a distinct purpose, and selecting the right one is vital for efficient treatment. Always consult with a wastewater treatment expert to choose the appropriate chemicals and ensure their effective application.
