B
BOD (Biochemical Oxygen Demand)
Pronunciation: /ˌbaɪ.oʊ.kɛm.ɪ.kəl ˈɒk.sɪ.dʒən dɪˈmɑːnd/The amount of dissolved oxygen needed by aerobic biological organisms to break down organic material present in a given water sample at certain temperature over a specific time period.
Example Usage
"CPCB mandates that effluent treatment plants must maintain wastewater discharge BOD below 30 mg/L."
C
CEMS (Continuous Emission Monitoring System)
Pronunciation: /sɛmz/The total equipment required to determine a gas concentration or emission rate using analyzer measurements and a conversion formula to provide data in units of the applicable emission standard.
Example Usage
"Power plants must install a stack CEMS to continuously report SO2, NOx, and CO emissions."
COD (Chemical Oxygen Demand)
Pronunciation: /ˈkɛm.ɪ.kəl ˈɒk.sɪ.dʒən dɪˈmɑːnd/An indicative measure of the amount of oxygen that can be consumed by chemical reactions in a measured solution, commonly used to quantify organic pollution in wastewater.
Example Usage
"Real-time UV-spectrophotometric sensors measure COD instantly without requiring chemical reagents."
N
NDIR (Non-Dispersive Infrared)
Pronunciation: /ɛn-di-aɪ-ɑːr/A spectroscopic method commonly used as a gas detector to measure the concentration of carbon oxides, sulfur dioxide, and other infrared-absorbing gases.
Example Usage
"The AuraStack CEMS-300 utilizes multi-channel NDIR cells to measure SO2 and NOx concentrations with zero drift."
R
RTDMS (Real-Time Data Management System)
Pronunciation: /ɑːr-ti-di-ɛm-ɛs/The cloud platform operated by the Central Pollution Control Board (CPCB) that ingests, processes, and displays real-time telemetry inputs from environmental monitoring systems across India.
Example Usage
"A telemetry implementation may formulate XML or other payloads compatible with the applicable CPCB or SPCB server specifications; confirm the current endpoint requirements before procurement."
S
SPCB (State Pollution Control Board)
Pronunciation: /ɛs-pi-si-bi/The regional government authority responsible for monitoring, regulating, and enforcing environmental compliance laws in their respective states.
Example Usage
"Plants in Faridabad must submit calibration certificates to the Haryana State Pollution Control Board."
T
TSS (Total Suspended Solids)
Pronunciation: /ˈtoʊ.təl səˈspɛn.dɪd ˈsɑː.lɪdz/The dry weight of particles in water that do not dissolve, which can be trapped by a filter, measured by turbidity or suspended solids analyzers.
Example Usage
"An online TSS sensor triggers alarms if the clinker effluent channel becomes muddy."
