Wastewater Treatment

Wastewater treatment is the process of purifying sewage or wastewater to remove contaminants prior to its discharge into water bodies. The generation of wastewater is a direct consequence of human activities. The wastewater treatment procedure entails the transformation of wastewater into water suitable for safe release into receiving bodies of water or for potential reuse. This multifaceted treatment process incorporates a combination of mechanical/physical, biological, and chemical methods. Depending on the specific treatment methodologies employed, wastewater treatment is categorized into the following:

  • Primary Treatment: Incorporates physical and chemical processes.
  • Secondary Treatment: Utilizes biological processes.
  • Tertiary Treatment: Includes advanced physical and chemical processes.
  • Sludge Treatment: Elimination/management of sludge generated during the wastewater treatment process.
Activated Sludge Treatment plant

The Activated Sludge Process (ASP) is an inherent biological wastewater treatment method, mainly for secondary treatment under aerobic condition (with dissolved oxygen). It involves introducing activated sludge into wastewater to rapidly break down impurities. This process includes aeration and agitation in an aeration tank, followed by settling in a clarifier, The Activated Sludge Process (ASP) is an inherent biological wastewater treatment method, mainly for se

Extended Aeration Activated Sludge Plant

The extended aeration process stands out among activated sludge variations as it combines sludge disposal with wastewater purification. It efficiently treats small-volume domestic and industrial waste without the need for primary sedimentation tanks. An extended aeration period facilitates aerobic digestion of most biological sludge. 

In the process, organic waste is partially oxidized and synthesized into new bacteria c

Biological Nutrient Removal Plants (BNR)

Carbon, nitrogen, and phosphorus are significant nutrients for aquatic life. However, excessive levels of these nutrients pose serious problems. Wastewater treatment facilities must adhere to strict nutrient effluent limits, covering phosphorus, nitrogen, carbon, and various micronutrients commonly found in wastewater. Nutrient-rich wastewater can lead to eutrophication, ammonia toxicity, and nitrate contamination of groundwater. Nutrient removal in wastewater is

5 Stage Bardenpho Treatment plant

The 5-stage Bardenpho treatment plant, known as the Bardenpho System, represents a specific design within the realm of activated sludge wastewater treatment. It is a prominent and accepted choice for Biological Nutrient Removal (BNR).

The Bardenpho treatment process is a highly efficient and widely adopted approach for the removal of organic matter, nitrogen, and phosphorus from wastewater. This method incorporates anaerobic,

Nitritation - Deammonification Plant

A Nitritation-Deammonification (ND) system is an advanced wastewater treatment method that combines two distinct biological processes: nitritation and deammonification, to remove nitrogen compounds efficiently. This energy-efficient approach eliminates the need for traditional nitrification, which converts ammonia to nitrate, a less desirable form of nitrogen that can contribute to eutrophication in natural water bodies.
