Snyder Industries 22 Gallon HDPE Vertical Liquid Storage Tank Opaque Resin

Small tank, opaque wall, plant-grade resin

A 22 gallon tank is the day tank on a pilot plant, the make-up tank on a lab skid, or the reservoir on a chemical feed cart, and a tank that light cannot reach keeps hypochlorite, peroxide and the light-sensitive reagents at strength longer than a translucent one does. What it shares with the largest tanks in the same line is the wall, sized for a liquid nearly twice as dense as water. Full, it puts 349 pounds on an 18 inch circle, which a bench or a paver supports; the concrete pad sizing guide covers a shared slab where several small tanks stand together. The tank sizing calculator sizes a day tank to the pump's rate and the refill schedule, and the tank sizing guide covers the reserve; at this size the reserve is measured in hours, and the tank is refilled from a carboy.

What is fitted

• Access: 2 inch lid; filled by funnel or drum pump from a carboy.
• Outlet: name the chemical when ordering so the bulkhead fitting matches it; a flexible line to the pump suction.
• Service limit: 120 F / 48 C.

A tank this small stands on a bench or a spill tray, bracketed so a snagged hose cannot drag it, with the dosing pump below the outlet so it primes by gravity. The opaque wall means no reading the level by eye: a sight tube on the outlet or a float switch does it, and a low-level float switch protects the pump. Keep the lid closed against vapor loss; the wall already keeps the light out. Label it with the chemical and the fill date, because an opaque tank tells you nothing by looking at it, and rinse it at every changeover, which takes a minute at this size.

Applications

Pilot plants, lab skids, chemical feed carts, small package treatment plants, and the bench reservoir that feeds a metering pump for a test with a light-sensitive reagent. One chemical per tank, labeled, refilled on a schedule the chemistry tolerates, and rinsed at every changeover, which takes a minute. Several of them are the make-up stage of a small reuse system, per the industrial water reuse tank topology article.

On the truck

At 9 pounds and 18 by 18 by 23 inches, the 1530000N52 ships by UPS rather than freight; the freight cost estimator shows the cost to your ZIP, and the listed price is before shipping. Unbox it, check the lid and the outlet fitting, and fill it once with water to prove the seal before the first chemical goes in. Mark the vent and the outlet on the outside of the shell so nobody caps the wrong one in the dark.
