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.

Diethylene Triamine Penta(Methylene Phosphonic Acid) Heptasodium Salt (DTPMP.Na7)
CAS 68155-78-2
Genuine, textbook fit. DTPMP is THE workhorse RO/NF membrane antiscalant — a penta-phosphonate with the broadest threshold-inhibition spectrum across CaCO3, CaSO4 and BaSO4, and the best thermal/high-pH stability of the commodity phosphonates, so it holds at the concentrate tail where LSI peaks. The heptasodium salt is the near-neutral, feed-dosable form (no pH depression on injection). CAS 68155-

Bis(HexaMethylene Triamine Penta (Methylene Phosphonic Acid)) BHMTPMPA
CAS 34690-00-1
Genuine fit for the specific high-LSI/high-hardness niche this page describes. BHMTPMPA is a high-charge-density, high-molecular-weight phosphonate marketed precisely for scale control where lower phosphonates lose Ca-tolerance and precipitate — i.e. high-hardness, high-alkalinity, elevated-temperature membrane and oilfield service. Directly serves CaCO3/CaSO4/BaSO4 threshold inhibition in the RO
