Snyder Industries 150 Gallon Heavy Duty Vertical Storage Tank

Sized to a metering pump, not a hose

A feed pump moves gallons a day through a small line, and a big outlet on a small tank is a reducer and a place for sediment to settle; the 1 inch fitting on this tank feeds the pump directly through an isolation valve, which is what lets the pump be serviced without draining the tank. At 150 gallons it is a couple of weeks of feed on most dosing duties and light enough that one person carries it in. The 1.9 wall takes the dense chemicals, and the white wall shows the level through it in daylight, the gauge most feed tanks run on. Full at the rating it puts 2,377 pounds on a 30 inch circle: a level slab per the concrete pad sizing guide, a spill tray or a berm when the liquid is regulated, and a strap to the wall behind it, because a tank this narrow and this tall goes over when it is empty. The tank sizing calculator turns feed rate and delivery interval into a volume, and the tank sizing guide covers the reserve to keep the pump wet between deliveries.

The 30 inch family, and the 29 inch tanks either side

The C34 is this tank in black for a pad in the sun, the N42 the cross-linked one for hypochlorite and peroxide, and the N48 the other chemical grade, all on the same 30 x 59 shell at this weight. The 1007300C26 is the 130 gallon at 51 inches and the 1008400C26 the 175 at 66, both an inch narrower, the sizes either side when the delivery interval says so.

The 1 inch outlet and the manway

• Outlet: 1 inch polypropylene female NPT bulkhead fitting, at the base; an isolation valve at the tank, a flexible connector to the pump, and the pump mounted below the outlet so it primes by gravity.
• Access: 18 inch threaded, vented manway, 59 inches up, opened from the floor; fill from a drum pump or a tote through a dip tube, and vent outside on anything that fumes.
• Service limit: 120 F / 48 C.

A low-level float, or a weight on the suction lance, stops the pump before it draws air; a feed pump that runs dry loses its prime and the plant loses its dose until someone notices. Keep the manway closed against vapor and evaporation, label the one chemical the tank holds, and stand it in a spill tray where the floor drains somewhere it should not. A tank this small is emptied and rinsed for a chemical change rather than switched over; the 1 inch fitting drains it in a few minutes.

Where a 150 gallon feed tank goes

The polymer or the coagulant day tank at a small water plant, a chlorine solution tank on a well site, the acid and caustic pair at a boiler room, a cooling tower biocide tank, and the supply on a pilot skid. Not a fire tank, which the fire-water reservoir design guide sizes in thousands of gallons and a water wall. Where a reuse system doses treatment chemical between storage stages, the industrial water reuse tank topology article shows where a tank this size sits in the train.

Shipping and the first fill

The 1012800C26 ships from Philippi, West Virginia as LTL freight at class 300; the freight cost estimator quotes it to your ZIP, and the listed price is before freight. One person carries 55 pounds through a door upright; at 30 inches across it fits. Fill it with water to the manway once and look at the outlet fitting for a weep, then drain and dry before the chemical goes in. Write the chemical and the date on the wall in paint marker; on a feed tank that is the label the inspector reads. Keep one spare gasket for the outlet fitting on the shelf; it is the part that fails on a holiday.
