2. Nitrogen
3. Chlorine gas
4. Hydrogen sulfide - ANSWER-Hydrogen sulfide
What happens with the solids produced in wastewater
treatment at Cascades Tissue? - ANSWER-Solids
produced in wastewater at Cascades Tissue is conveyed
across onto a pad where a semi-truck picks them up.
Solids are then driven to farmer fields in the area and they
