The challenge of treating high BOD sewage wastewater is a significant environmental crisis in the city of Delhi. It stands out as an issue that continues to face stiff pressure from the ever-increasing populations and continues growing its various infrastructures that manage the city's wastewater. Netsol Water is a leading Sewage Treatment Plant Manufacturer in Delhi, offering solutions for waste water management.
Explaining the BOD Challenge
Biochemical Oxygen Demand, or BOD, is one of the significant parameters for determining the amount of oxygen required to break down organic materials present in sewage for microorganisms. In Delhi, the BOD levels in sewage are often alarmingly high, sometimes exceeding 300 milligrams per litter (mg/L), well above the standard limit of 30 mg/L set by the Central Pollution Control Board (CPCB) of India.
Netsol Water is one of the best Sewage Treatment Plant Manufacturer in Delhi, offering solutions for waste water management. This high BOD is a significant challenge in the treatment since it demands intensive processing and energy-intensive aeration in getting rid of the organic pollutants. The sheer volume of wastewater generated in the city coupled with its high BOD content, has overwhelmed existing treatment infrastructure forcing the partial or even untreated effluent into the water bodies around the city.
Aging Infrastructure and Capacity Constraints
In Delhi, the main reasons for high BOD in its sewage are aging and inadequate wastewater treatment infrastructure. Most of the city's STPs were built decades ago and have long exceeded their design capacities, which most of the cities cannot keep up with, let alone population growth and increased generation of wastewater.
The total treatment capacity of STPs in Delhi is just 2,330 million litters per day whereas the generation of wastewater is around 3,800 MLD. The gap between the treatment capacity and the generation of wastewater has been forcing untreated or partially treated effluent into the water bodies of the city-Yamuna River-and also enhanced the pollution problem.
Lack of Adequate Collection and Conveyance of Sewage
One of the most important issues which need to be addressed to counter high BOD is lack of an integrated sewerage collection and conveyance system in the city of Delhi. In fact, in most of the cases, almost all the un authorized colonies and slums do not have any regular sewer networks and thus untreated sewage is given out directly into the water bodies and drains of the city.
For one, there are many slums and informal settlements within the city which cause jamming in waterways and obstruct wastewater flow, resulting in an aggregation of organic matters and other pollutants.
Lack of Adequate Treatment and Disposal
Even in the areas with treatment plants for wastewater, treatments are mainly marred by several factors that include use of outdated technologies, poor maintenance and operations, and a deficiency of well-trained personnel for the proper management of the treatment plants.
The third aspect is the disposal of the treated effluent and the management of the sludge produced. The treatment sometimes produces effluent rich in organic matter and other pollutants, which is eventually discharged into water bodies with little or no dilution or treatment at times, causing further degradation of the environment, continuously.
Towards a Sustainable Solution
Netsol Water is top on Sewage Treatment Plant Manufacturers in Delhi, offering sustainable solutions for waste water management. Addressing the challenge of high BOD sewage wastewater in Delhi will need to be multi-pronged and focus on the root causes of the problem. This shall include:
1. Infrastructure upgradation and expansion: Investment in upgrading as well as expanding modern sewerage treatment infrastructure in the city to increase capacities and enhance efficiency.
2. Sewerage Collection and Conveyance Upgraded: It will provide a comprehensive sewerage collection network by formalizing informal settlements and removing encroachment in drainage channels.
3. Advanced Treatment Technologies: Introduce advanced wastewater treatment technologies, including membrane bioreactors and sequential batch reactors that would enhance the removal of organic matter and other pollutants.
4. Close Monitoring and Enforcement Strengthen and Enforce: The regulatory framework to ensure that standards of discharge are complied with and best management practices for wastewater are encouraged.
5. Public Awareness and Public Participation: Creating awareness among the local communities on the importance of proper management of wastewater and involving them in active conservancies.
Thus, by concerted and sustained efforts to address these challenges, Delhi might develop a better, more environmental-friendly system for the management of wastewater and sewage, hence a better environmental health of the city as well as its citizenry.
