Our Expertise & Proven Track Record

With a legacy of over 200 completed EIA studies, San Envirotech is recognized for technical precision and regulatory integrity. Our multidisciplinary team ensures every project aligns with the latest MoEF&CC guidelines, facilitating a seamless transition from project conception to obtaining Environmental Clearance (EC).

With over 15 years of expertise, our air quality team ensures that your project’s emission profile remains well within the National Ambient Air Quality Standards (NAAQS), even under the most challenging weather conditions.

Our Core Air Quality Services

1. Advanced Air Dispersion Modeling

We utilize industry-standard, MoEF&CC-approved software to simulate the transport and transformation of pollutants from stacks and fugitive sources.

  • Point, Area, and Volume Sources: Modeling emissions from chimneys, storage piles, and process areas.
  • AERMOD & ISCST3 Modeling: Using the latest regulatory models to predict Ground Level Concentrations (GLC) of SO2, NOx, PM10, PM2.5, and VOCs.
  • Complex Terrain Analysis: Specialized modeling for projects located in varied topographical regions.

2. Ambient Air Quality (AAQ) Baseline Studies

A model is only as good as its data. We conduct rigorous primary monitoring to establish an accurate baseline:

  • Micro-Meteorological Monitoring: In-house installation of weather stations to record wind speed, direction, temperature, and humidity.
  • Seasonal Monitoring: Capturing air quality data across different seasons to account for atmospheric inversions and monsoon effects.

3. Stack Emission & Fugitive Analysis

  • Adequacy Studies: Evaluating if your proposed stack height and Air Pollution Control Devices (APCD) like ESPs, Bag Filters, or Scrubbers are sufficient to meet emission norms.
  • Isokinetic Stack Sampling: Precision measurement of flue gas parameters to validate theoretical models.
  • Odor & VOC Analysis: Specialized modeling for the Pharmaceutical and Pesticide industries to mitigate odor nuisance in nearby residential zones.

Strategic Environmental Management Plans (EMP)

Beyond just modeling, we provide actionable solutions:

  • Greenbelt Design: Using modeling results to strategically place tree plantations that act as natural "pollutant sinks."
  • Mitigation Strategies: Recommending process changes or advanced filtration technologies to reduce the predicted impact on sensitive receptors like schools or hospitals.

Why Choose San Envirotech?

  • Technical Precision: We don’t just provide maps; we provide validated scientific data that stands up to the scrutiny of the Expert Appraisal Committee (EAC).
  • In-House Meteorological Data and AERMOD & ISCST3 Modeling: Our team manages primary data collection, ensuring that the modeling input is site-specific and 100% accurate.

Ensure your emissions stay within safe limits.
