Tank Size & Geometry
▶
Select geometry and size based on your inlet flow rate. Rectangular tanks provide longer detention time; trapezoidal geometry provides an extended beach for drier, more concentrated discharge. Selecting a tank auto-suggests the standard holding tank size and pre-selects DWTH heating.

2
Holding Tank — Heating Type
▶
Select the heating method for the scum holding tank. Heated tanks maintain scum pumpability — especially critical for high-FOG applications and cold climates. DWTH is the standard selection.
NN
No Holding Tank
Excluded from scope
DWTH Standard
Double-Walled – Tenco Hot Water
Tenco Hydro-provided recirculated hot water heating; recommended for most applications

Plant-provided hot water supply; double-wall tank
DWIH
Double-Walled – Immersion
Internal immersion electric heating element
EH
Electric Blanket / Heat Trace
Suitable for moderate FOG applications
NH
No Heating
Not recommended for high-FOG service
3
Holding Tank — Size
▶
Select holding tank volume. The standard size for your selected concentrator is highlighted. Size is based on scum production rate, heating method, and required storage duration.
NN
No Tank
Skip if NN selected in Step 2
HT450 Suggested
HT450 — 450 Gallons
5 ft dia × 2′-9″ side water depth

Custom Volume
Replace XXX with volume in gallons — contact Tenco Hydro
4
Material of Construction
▶
Select tank and mechanism material. 316SS is preferred for chloride-bearing or aggressive service environments.

304SS Suggested
304 Stainless Steel
General-purpose stainless
316SS
316 Stainless Steel

6″ avg pitch; ≥3,100 lbs working load
6
Inlet Manifold
▶
Controls how scum-laden flow reaches the concentrator. Selecting a manifold tier will auto-suggest and pre-select the standard controls package for Step 7 — you can override if needed.
