Snyder Industries 400 Gallon HDPE Vertical Chemical Storage Tank in White

The bulk tank for a small system

Four hundred gallons is the bulk tank at a small water system or a single-process plant: two totes' worth, filled from a tote pump and drawn down by a dosing pump over weeks. Size it to the feed rate and the delivery interval with the tank sizing calculator, and carry the reserve the tank sizing guide recommends. The list below is the resin's rated chemistry; the chemical compatibility database gives the rating for your liquid at its concentration, which is a separate question from the weight rating.

Snyder's 360 to 440 gallon tanks

The N42 is the cross-linked twin at the same 85 pounds, for hypochlorite and the other oxidizers; the N48 is another resin option in the same shell, 2 inches shorter. The two 53 inch tanks are heavier-wall vessels on a wider base: the 5760100N42 gives up 40 gallons for a 59 inch height, and the 5770100N42 adds 40 gallons at 69 inches, 45 pounds heavier than this tank.

Openings, sampling and labels

• Outlet: 2 inch, at the bottom of the sidewall.
• Access: 18 inch threaded, vented manway.
• Service limit: 120 F / 48 C.

Three practices make a small chemical tank a safe one. Choose the level sender for the chemical with the level gauge selection guide. Draw samples that represent the tank and not its stratified top, per the bulk tank chemical sampling protocol. And label it so the fire inspector and the workplace inspector both read the same thing, NFPA 704 diamond and GHS pictograms reconciled as the tank label and signage compliance guide describes.

Jobs it is bought for

Hypochlorite, caustic and coagulant storage at small water and wastewater systems, acid and inhibitor feed at cooling towers, brine for softeners, and reagent storage on a pilot plant. A 45 inch tank fits a standard spill pallet; keep one chemical per tank and keep the manway closed against vapor loss.

Freight for a 400 gallon tank

The 1740000N45 ships palletized as LTL freight (NMFC 156600-02) at a class rate; the freight cost estimator shows it for your ZIP, and the listed price is before freight. Eighty-five pounds comes off a liftgate and walks in on two hands. Water-fill it to the manway and hold it before the chemical connection is made.

Chemicals this resin is rated for, with the fitting and gasket to order

These are the chemicals listed for this tank at the concentrations shown. Each links to the full compatibility page; confirm your exact concentration and temperature there or in the chemical compatibility database before ordering.

• sulfuric acid at 98% (CPVC fittings, Viton gaskets)
• hydrochloric acid at 37% (PVC, Viton)
• phosphoric acid at 85% (PVC, Viton)
• hydrofluoric acid at 48% (PP/PVC, Viton)
• hydrofluosilicic acid at 26% (PP/PVC, Viton)
• sodium hypochlorite below 16.5% (PVC, Viton), and
• hydrogen peroxide at 50% (PVC, Viton). It also handles the water-treatment coagulant and salt lineup:
• ferric chloride at 50%
• ferric sulfate at 60%
• ferrous sulfate at 20%
• aluminum sulfate at 50%
• polyaluminum chloride
• calcium chloride at 40%
• magnesium chloride at 30%
• sodium carbonate at 30%
• potassium carbonate at 50%
• potassium hydroxide at saturation
• sodium bisulfite
• sodium bisulfate
• sodium thiosulfate at 40%, and
• zinc orthophosphate (PVC or PVC/PP fittings, EPDM gaskets on these). For fluids stations and fleet yards it is documented for
• DEF at 32.5% and
• urea solution at 50%, along with
• ethylene glycol and
• acetic acid at 60%, plus
• peracetic acid at 30% and ozonated water up to 10 PPM.
