Nutrient Removal — Process Challenge

Biological Nutrient Removal — Denitrification Carbon Source

Plants held to low total-nitrogen limits dose an external carbon source to feed denitrifying bacteria when influent BOD is insufficient. Methanol, acetate and glycerin are the standard electron donors, bought in bulk as a recurring nutrient-compliance spend

Solution Approach

RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.

Typical Treatment Workflow
1
Water & System Assessment
Characterize the water and the system — hardness, alkalinity, pH, TDS/conductivity, microbial load, and the metallurgy and temperatures of the equipment being protected.
2
Program & Chemistry Selection
Match coagulants, flocculants, scale and corrosion inhibitors, biocides, or pH adjusters to the water profile and discharge limits, factoring compatibility with any existing program.
3
Jar Testing & Dosing
Confirm coagulant and flocculant dose and feed point by jar test, set inhibitor and biocide treat rates, and size packaging (drums, totes, bulk) to consumption.
4
Monitoring & Control
Track residuals, turbidity, ORP, corrosion coupons, and effluent compliance, adjusting chemistry and dose as feedwater and load change.
