Stainless Steel Anti-Corrosion Electric Hoist for H₂S
In a nutshell: Kelude Heavy Industry provides crane configuration solutions for wastewater treatment plants, covering all four process stages—inlet, biological treatment, sedimentation, and sludge dewatering. With lifting capacities from 2 to 32 t and spans from 6 to 30 m, the total investment in plant-wide lifting equipment ranges from approximately $18,000 to $178,000. The feed pump house is equipped with stainless steel anti-corrosion electric hoists (5–16 t), the biological treatment zone uses stainless steel anti-corrosion hoists (3–10 t), the sedimentation tank area features stainless steel cantilever jib cranes (2–5 t), and the sludge dewatering room is fitted with stainless steel anti-corrosion KBK cranes (1–5 t)—delivering full-process anti-corrosion hoisting solutions from water intake to sludge dewatering.

Key Characteristics of Wastewater Treatment Plant Zones
Wastewater treatment plants consist of four main zones—the feed pump house, biological treatment area, sedimentation tank area, and sludge dewatering room—all of which share challenging operating conditions: high humidity (RH ≥ 90%), corrosive gases (H₂S/NH₃/Cl₂), and acidic environments (pH 5–9). Every crane installed in these areas must incorporate a stainless steel anti-corrosion design. In the feed pump house, individual pumps weigh between 2 and 10 tons, and the wastewater contains hydrogen sulfide at concentrations of 10–200 ppm. We recommend SUS304 stainless steel electric hoists (5–16t capacity) paired with hot-dip galvanized rails and IP66-rated stainless steel electrical control boxes, with motors equipped with isolated fresh-air ventilation ducts. The biological treatment area primarily uses aerators, flow pushers, and agitators (500–5,000 kg), where stainless steel underslung cranes or KBK systems (1–5t) are recommended, featuring hot-dip galvanized rails and stainless steel lifting points. In the sedimentation tank area, scraper bridge girders and drive assemblies weigh 2–8 tons; we recommend stainless steel jib cranes mounted on the walkway plates along the tank perimeter. The sludge dewatering room handles the heaviest equipment—centrifuges from 3 to 10 tons and plate-and-frame filter presses from 5 to 15 tons—where stainless steel anti-corrosion KBK systems with pneumatic balancers are the ideal solution. Kelude Heavy Industry provides comprehensive stainless steel anti-corrosion crane solutions for wastewater treatment plants across all four zones.
