Selenium Removal in Water & Wastewater

Selenium treatment performance depends on influent chemistry, co-contaminants and required discharge targets. Onterris develops treatment strategies that align system selection and operating conditions with site-specific performance needs.

Iron-based media treatment supports removal of oxidized metals and metalloids in a single step. This approach can address selenium alongside arsenic, chromium, cadmium, molybdenum and other target contaminants within the same treatment train.

Many facilities need stronger treatment performance without a full system rebuild. Onterris supports retrofit-friendly deployment approaches that can integrate into existing infrastructure while improving treatment reliability and regulatory alignment.

Effective treatment starts with understanding how a solution will perform under real conditions. Onterris applies testing, evaluation and implementation insight to help clients move forward with greater confidence in treatment outcomes and operating stability.

Selenium challenges often sit within broader water, wastewater and project delivery demands. Onterris connects treatment planning with regulatory, operational and lifecycle priorities across sectors that need durable environmental performance.
