§ 07Industries / IND-04
Water treatment & municipal
Water treatment is the clearest case in our catalog for buying grade B-. The chemistry is mostly aqueous and non-permeating, nobody outside the plant ever sees the container, and the volumes are large enough that the per-unit saving is substantial.
- Flow pattern
- Steady, high volume, year-round
- Chemistry
- Mostly aqueous, mostly non-permeating
- Appearance
- Irrelevant — containers are never customer-facing
- Procurement
- Often public tender with documentation requirements
§ 07.aWhat arrives in totes
The products we see in this sector.
- Coagulants — alum, ferric, PAC
- Polymer flocculants
- Sodium hypochlorite
- Caustic soda and lime slurry
- Corrosion and scale inhibitors
- Fluoride and phosphate dosing solutions
- Dechlorination chemistry
§ 07.bWhat we recommend
Specification for this duty.
- Default grade
- B- — tested, sound, cosmetically worn
- Gasket
- EPDM for most; Viton for concentrated hypochlorite
- Pallet
- Plastic for washdown environments
- Closure
- Vented; many plants gravity-dose
- Valve
- 2" ball; stainless where hypochlorite is concentrated
- B-
- Recommended grade
- 48units
- Per trailer
- 262lb CO₂e
- Saved per reused unit
- 0
- Reasons to buy new here
Tested and sound; cosmetics irrelevant.
Standard 275 gal composites.
Against a new replacement.
Unless a tender specifies it.
§ 07.cReference
Water treatment chemistry and container implications
| Chemical | Permeation | Gasket | Notes |
|---|---|---|---|
| Alum, ferric, PAC coagulants | None | EPDM | Excellent reuse stock; may stain |
| Polymer flocculants | None | EPDM | Viscous — specify 3" butterfly |
| Sodium hypochlorite | None | Viton | Off-gasses; vented cap essential |
| Caustic soda | None | EPDM | Full reuse |
| Lime slurry | None | EPDM | Settles hard; declare for wash programme |
| Corrosion inhibitors | Low | Check per product | Often amine-based |
| Fluoride solutions | None | EPDM or PTFE | Full reuse |
§ 07.dSector-specific problems
What goes wrong here, and what we do about it.
Four problems we see repeatedly in this sector, with the answer rather than a sales line.
The problem
Sodium hypochlorite degrades gaskets and off-gasses
Our answer
Viton gaskets and vented caps as standard. Hypochlorite also bleaches bottle interiors, which is cosmetic and worth knowing is normal rather than a defect.
The problem
Public tender documentation requirements
Our answer
We supply per-unit test records, wash programme codes, previous-contents chains and UN recertification statements. Send us the tender schedule and we will complete it properly.
The problem
Large volumes and tight budgets
Our answer
Grade B- is the right answer here and it is the cheapest tested stock we sell. We will not sell you up to A- for a dosing application.
The problem
Lime slurry and other settling products are hard to drain
Our answer
Declare it. Settled lime needs a different wash programme and we will quote accordingly rather than discovering it on the line.
