Dust Monitoring for Air Purification - Case Study
Overview
Heavy welding, metal cutting, and buffing activities inside the JCB manufacturing plant of India generate high amounts of Particulate Matters of 2.5 microns (PM2.5) & 10 microns(PM10) (exceeding 300 ug/m3). The situation demanded air quality monitoring and suppression of pollutants. Oizom deployed Dustroid to monitor real-time dust particle generation within the facility. Dustroid solution helped in setting up a threshold for the particulates and activate the air purification systems immediately.
Problem
Automobile manufacturing process produces air pollution within the plant due to continuous welding, metal cutting and buffing activities. The situation is severe in heavy vehicle manufacturing plants like JCB due to scaled-up execution of these activities. Metal welding creates extreme heat and disperses minute metal particles like copper and manganese in the air. These small metal particles can be easily inhaled and settle in the lung tissues and nervous system to cause damage. Workers are at risk within the facility without a comprehensive dust control system. Devic Earth has designed Pure Skies purifier, an ambient air quality purifier to remove dust particles from the air. They installed a purifier at JCB’s manufacturing plants. Continuous operation of the air purifier is expensive, and hence, the real challenge was to assess the impact and accordingly switching on the Pure Skies purifier.
Offered Solution
Oizom offered collaboration with Devic Earth for automating the Pure Skies purifier’s operation within JCB manufacturing plant by installing Dustroid along with the purifiers. Dustroid monitors dust particles (PM2.5 & PM10) and generates real-time data. It provides quantitative analysis for particle size distribution and concentration measurements. It helped to set up a PM threshold limit beyond which the dust particles need to be removed from the plant. The data gathered by Dustroid allowed for the identification of the critical hours to switch on the air purifier. Data-driven operation of purifier reduces the power consumption and ultimately cuts down the operational cost.
Impact
Installing Dustroid helped the JCB manufacturing plant to reduce the exceeded dust exposure. The combined effect of Dustroid and Pure Skies purifier eliminated the dust pollution from the facility to a great extent. The objective was achieved by hitting the correct time of putting the purifier in use to optimize the purification process. It substantially reduced the operational cost of the air purifier by switching it on only when required. Reduction in dust levels also improved the health conditions of the workers.

Air Quality Monitoring for Schools and Universities - University / Academia / Research
Students spend more than 25% of their day at School and University campuses. Poor air quality levels at the school campuses put the most vulnerable group at the highest risk. UNICEF and WHO have stated that young lungs are more susceptible to air pollution. Exposure at a young age when the immune system is weaker may lead to permanent respiratory health issues such as asthma and lung cancer. This renders air monitoring essential in and around the school and university campus.
