NESCO Systems
Sometimes it is desirable to wet process material through a direct application of water. DSI Water Spray Systems use a high-pressure pump and a variety of spray nozzles to add the right amount of water to your material.
NESCO Theory
NESCO spray systems control dust by producing a highly atomized mist that suppresses airborne particulates larger than 15um while adding from 0.2% to 0.5% moisture by weight to the process to prevent visible dust emissions from downstream unit operations. Water spray systems work on the principle of agglomeration for airborne dust, by producing water droplets that are the same size as the dust particles. These droplets collide with the dust particles and create larger particles that gravity brings back to the ground/process. The key component with water sprays is that the smallest droplet possible on a high pressure water spray system is around 20um, which will be effective for visible and inhalable dust, but not respirable airborne dust. The downstream reduction of dust created by the moisture addition will reduce the creation of respirable and visible dust.
