Sewage Treatment Plant Manufacturer in Faridabad

Faridabad, located in the National Capital Region (NCR), is one of the fastest-growing industrial cities in India. With rapid urbanization and industrialization, sewage generation has increased significantly in Faridabad. Proper collection, transportation, treatment, and disposal of sewage are crucial to maintaining public health standards and environmental sustainability. Sewage treatment plants play an important role in treating the sewage before discharging the treated effluent into water bodies or using it for non-potable applications. The market for sewage treatment plants in Faridabad has seen rising demand with increasing environmental regulations and sewage volumes. Netsol Water is a renowned sewage treatment plant manufacturer in Faridabad and based in Greater Noida. With over 10 years of experience in the water and wastewater treatment industry, Netsol Water manufactures a wide range of sewage treatment plants catering to industries, housing societies, commercial buildings and municipalities in Faridabad and across India.

Overview of Sewage and Need for Treatment

Sewage refers to used water from domestic, institutional, commercial and industrial establishments containing various kinds of waste, including human excreta, suspended solids, colloidal particles, organic matter, oils and grease, metals, nutrients, viruses, pharmaceuticals and more. Untreated or partially treated sewage is a major source of water pollution and spreads diseases.

Some key statistics on sewage generation and treatment status in India:

  • Around 61,754 million liters per day (MLD) of sewage is generated from urban centers in India
  • Treatment capacity exists for only ~23,277 MLD sewage (37% of generated)

Proper sewage treatment before discharging into water bodies or land is essential to:

  • Remove solids, organics, nutrients, metals and pathogens
  • Prevent contamination of water sources
  • Protect public health
  • Enable reuse of treated sewage for non-potable uses
  • Comply with regulatory discharge norms

Treatment of sewage comprises physical, chemical, and biological processes to meet the discharge norms for Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), nutrients and pathogens.

Standards and Regulations for Sewage Treatment

The key regulations governing sewage treatment in India include:

  • The Environment Protection Act, 1986 and Rules 1986
  • Water (Prevention and Control of Pollution) Act, 1974 and Rules, 1975
  • National Green Tribunal rulings on sewage discharge
  • Central Pollution Control Board (CPCB) / State PCB discharge norms

Some key parameters and norms for treated sewage discharge as per the CPCB include:

Parameter: Norm for Discharge into Water Bodies

Biochemical Oxygen Demand: Less than 30 mg/l Chemical Oxygen Demand – Less than 250 mg/l
Total Suspended Solids: Less than 100 mg/l Total Nitrogen – Less than 100 mg/l Total Phosphorus – Less than 5 mg/l Fecal Coliform: Less than 1000 MPN/100 ml

Additionally, State Pollution Control Boards have the authority to stipulate more stringent discharge norms if required to meet the water quality criteria of the receiving water body.

Thus, sewage treatment plants must be designed and operated to reliably meet the prevailing discharge norms. Additionally, online monitoring of treatment plant discharge is mandated in many cases.

Sewage Treatment Process and Technologies

Sewage treatment typically involves three stages: primary, secondary and tertiary treatment. Primary treatment removes suspended solids and other gross solids through physical processes. Secondary treatment uses biological treatment processes and removes dissolved and suspended organic matter, promoting biological stabilization. Tertiary treatment comprises disinfection and advanced methods to remove recalcitrant organics, nutrients and pathogens.

Various technologies used in sewage treatment include:

Primary Treatment

  • Bar Screens: Removal of coarse solids >10 mm size
  • Manual / Mechanical Screens – Removal of solids 1-10 mm size
  • Grit Chambers: Settling of sand, gravel, metal pieces
  • Primary Clarifiers: Settlement of suspended solids

Secondary Treatment

  • Activated Sludge Process: Aerobic biological treatment
  • Membrane Bioreactor: Ultrafiltration membranes for solid-liquid separation
  • Sequential Batch Reactor: Cyclic aeration basin operation
  • Rotating Biological Contactor: Rotating media with biomass growth

Tertiary Treatment

  • Filtration: – Rapid gravity sand filters, microfilters or ultrafilters
  • Disinfection: – Chlorination, UV irradiation, Ozonation

Additionally, nutrient removal, metals removal, and water reuse systems may also be incorporated as required to meet the effluent standards and enable reuse.

Odor control units, machinery cooling systems, and back-up power units are also important supporting infrastructure.

Challenges and Opportunities in the Sewage Treatment Sector

Some key challenges faced in the sewage treatment industry include:

  • Increasingly stringent discharge norms
  • Land and power constraints for setting up and expanding facilities
  • Limited investments allotted for sewage infrastructure
  • Seasonal variation in sewage characteristics
  • O&M constraints – lack of trained manpower, financial resources
  • Reluctance for reuse among stakeholders for non-potable applications

However, there are also significant emerging opportunities:

  • Swachh Bharat and Smart Cities programs are increasing momentum in sewage management
  • Increasing environmental awareness among the public accelerates projects
  • Availability of land through industrial parks and clusters
  • Progress in tertiary treatment technologies – MBR, MBBR for reuse
  • Automation and remote monitoring technologies improving O&M
  • Mandates on industrial water recycling and zero liquid discharge
  • Water scarcity makes reuse inevitable for industry and large residential complexes

Companies like Netsol Water, having both conventional and advanced sewage treatment technologies, strong project execution capabilities, and O&M services, are well-positioned to tap the upcoming opportunities in this sector.
