Effluent Water Audit Service, India

Effluent Water Audit

An effluent water audit is a systematic assessment of industrial wastewater streams to evaluate their quantity, quality, and compliance with environmental standards. It helps identify treatment gaps, optimize reuse potential, and ensure adherence to CPCB guidelines.

Why Effluent Auditing is a Critical Business Responsibility

Industrial and infrastructure facilities today are under increasing pressure to meet stringent environmental discharge norms. Failure to comply can result in operational shutdowns, environmental damage, or heavy penalties from the Central and State Pollution Control Boards. At iFluids Engineering, we don’t just test effluents—we deliver holistic, actionable audits that help clients achieve and maintain full compliance with CPCB General Standards (Schedule VI) and Industry-Specific Effluent Norms (Schedule I) under the Environment (Protection) Rules, 1986.

Our audits are rooted in detailed regulatory interpretation, site-specific diagnosis, and performance benchmarking, ensuring that your business is aligned not only with the law but with best practices for environmental stewardship and sustainability.

What We Offer – Comprehensive Effluent Audit Solutions

  • Regulatory Compliance Assessment
    • Evaluation of discharge against limits specified for inland surface water, public sewers, land irrigation, and marine coastal areas.
    • Parameter-wise comparison for pH, BOD, COD, TSS, heavy metals (Pb, Cr, Hg), oil & grease, cyanide, fluoride, and ammonia.
    • Industry-specific evaluation for sectors such as petroleum refining, textiles, fertilizer plants, pulp & paper, and pharmaceuticals.
  • Wastewater Load & Generation Mapping
    • Verification of wastewater generation volumes per tonne/unit of product as per CPCB limits.
    • Flow metering audits for process effluents, cooling water, and blowdowns.
  • Treatment System Audit
    • Review of primary, secondary, and tertiary treatment components (e.g., ETPs, RO units, clarifiers, neutralizers, chlorinators).
    • Efficiency assessment based on removal percentages for BOD, TSS, phenols, and sulphides.
    • Validation of oil-water separators, equalization tanks, and sludge handling units against CPCB design guidelines.
  • VOC & Fugitive Emission Management
    • Evaluation of closed drainage systems, vapour-sealed junctions, and cover systems for floating tanks.
    • VOC control audit for benzene, toluene, and xylene during storage and transfer.
    • Inspection of LDAR (Leak Detection and Repair) programs, including ppm threshold checks for valves, compressors, seals, and connectors.
  • Process-Specific Pollution Control
    • Stack emissions audit for furnaces, SRUs, boilers, and FCC units with real-time/periodic SO₂, NOₓ, CO, PM, and VOC monitoring.
    • Sulphur recovery validation for refineries (>98.7% for SRUs >20 TPD).
    • VOC emission audits from effluent handling areas, collection pits, and open channels.

Types of Effluents Considered

In our comprehensive effluent water audit services, we evaluate a wide range of wastewater streams, ensuring environmental compliance and process optimization.

We analyze six major effluent streams—process water, blowdowns, sanitary waste, stormwater, and leachates—under our industrial water audit services. This ensures compliance with CPCB standards and supports ZLD and water reuse goals. Optimized assessment drives better treatment design and sustainable discharge practices.
Types of Effluents

Effluent streams can vary significantly across industries. Our audits address all major categories:

  • Process Effluent – Water used in chemical processing, extraction, reaction, or formulation (typically high in BOD, COD, pH variance, and toxic compounds).
  • Cooling Tower Blowdown – Often high in TDS, silica, and treatment chemicals.
  • Boiler Blowdown – Contains dissolved solids, phosphate, and hydrazine.
  • Sanitary Wastewater – Typically domestic waste, analyzed separately, and mixed with industrial streams.
  • Stormwater Runoff – Audited for oil, grease, suspended solids, and potential hydrocarbon traces near tank farms.
  • Leachates and Drainage Effluent – Particularly from landfills, solid waste yards, and waste pits.

Effluent Audit Process Flow

  1. Effluent Mapping – Identify and categorize all effluent sources across the facility.
  2. Sample Plan & Collection – As per BIS/ISO/APHA protocols, point-specific samples are drawn.
  3. Flow Monitoring & Mass Balance – Installed flow meters or manual gauging for volumetric checks.
  4. Lab Analysis – Accredited third-party labs or in-house validated labs perform analysis.
  5. ETP Process Evaluation – Check dosing, retention time, sludge separation, disinfection.
  6. Compliance Review – Results mapped against Schedule VI or Schedule I limits.
  7. Reporting – Clear observations, non-compliances, root causes.
  8. Remediation Plan – Short-term and long-term suggestions with budget notes.
