Recently, the self‑developed rotary‑disc oil skimmer from Qingdao Huahai Environmental Protection completed on‑site water‑immersion testing and project acceptance at a southern river project site. Its operational performance far exceeded the customer’s expectations. The partner immediately confirmed renewal of the original contract and placed an additional purchase order for new‑batch equipment, recognizing Huahai Environmental Protection’s technical strength through tangible procurement.

At the acceptance site, construction workers wearing safety gear steadily carried the yellow‑and‑blue rotary‑disc oil skimmer to the riverbank. After quick pipeline connection, the equipment was deployed onto the water surface. Orange oil booms were laid in advance to enclose an oil‑recovery working area on the river. Floating in the designated water zone, the skimmer adsorbed floating oil on the water surface via rotary discs, and the recovered oil was smoothly diverted ashore through hoses. A simulated river floating‑oil pollution scenario was created on site. Despite interference from natural water flow, the oil skimmer ran stably with qualified disc adsorption efficiency. Floating oil was thoroughly collected without oil leakage or missed recovery. Compact and easy to transport, the whole set features simple start‑stop operation, making it suitable for emergency oil‑removal scenarios in various water bodies including rivers, lakes, waterways and reservoirs.

This rotary‑disc oil skimmer represents Huahai Environmental Protection’s independent R&D achievement accumulated over years of dedication to water‑area oil‑spill treatment. Drawing on the enterprise’s technical expertise in the full‑chain environmental‑protection equipment for oil containment and oil recovery, the product features optimized float structure and rotary‑disc materials, combining water‑corrosion resistance, high oil‑absorption rate and lightweight portability. Different from traditional large‑sized oil‑skimming equipment, this compact model can be carried and deployed by manual labor. It enables rapid on‑site response to sudden oil‑pollution emergencies, effectively filling the equipment gap for emergency oil cleaning in small‑and‑medium‑sized water bodies. From drawing‑board R&D and workshop trial production to repeated water‑area trial runs, the enterprise polishes its products based on real‑world water‑site working conditions, rather than relying on ideal laboratory parameters. All mass‑produced models have passed practical on‑water tests.

Having long engaged in the water‑pollution‑prevention equipment sector, Huahai Environmental Protection insists on verifying product quality through field tests and delivering product value via practical application outcomes. It has successively secured domestic and overseas project orders with its series of oil booms and oil skimmers. The customer’s contract renewal and additional purchase this time serve as direct market recognition of its self‑developed products.

Building on its existing technical advantages, Huahai Environmental Protection will further explore market demands for water‑body oil‑pollution treatment, iterate and upgrade oil‑skimming equipment, develop more market‑oriented environmental‑protection devices, and steadily advance in the water‑environment protection industry.
