- Food and beverage wastewater with high organic loads
Yes. Specify inner liners made of SS304 or SS316L, which tolerate temperatures up to 80°C.
Panels are engineered with flexible joints and reinforced base rings to absorb ground motion. Compliance with ASCE/SEI 7-22 standards is mandatory in earthquake zones.
Standard tanks range from 10-100 ft (3-30m). Custom designs can exceed 150 ft (45m) with auxiliary support structures.
Yes. Bolted tanks can be dismantled and reassembled at new sites, unlike welded or concrete structures.
