Macurco Common Applications

Wastewater Treatment Plants

Water / Wastewater treatment facilities take disturbed or unhealthy water and make it environmentally safe. This water, which can contain chemicals, oils, and human waste, endures a process of treatment and purification that utilizes chemicals and toxins that can potentially threaten personnel at the facility or the facility itself.


Due to growing cities, old landfills are being converted into commercial or residential developments. Due to the dangers of methane seeping up through the ground, the need to monitor methane levels is being required.

Oil Refining

Hydrogen sulfide occurs naturally in crude oil (sour crudes) and can be generated from refining processes, including hydro-cracking, hydrolysis and elemental sulfur production.
