2025-10-15
Recently, the original, high‑quality group standard “FHG‑Type Reverse‑Lifting Bar Screen Cleaner,” drafted under the leadership of Huahong Water Services Group Co., Ltd., has been approved by a panel of experts. This standard specifies the structural, performance, testing, and inspection requirements for FHG‑type reverse‑grapple bar screens, providing comprehensive technical specifications to support the design, manufacture, and application of this equipment in urban drainage systems. By leveraging standardized design and testing procedures, it ensures the equipment’s reliability and efficiency under complex operating conditions, thereby advancing technological progress and promoting standardized development within the environmental protection equipment industry. It thus holds significant practical value and serves as an important guide for the sector.
Application Background
Against the backdrop of rapid urbanization and increasingly stringent environmental protection requirements, the construction and optimization of wastewater treatment facilities have become particularly critical. As one of the core pieces of equipment in wastewater treatment plants, the FHG‑type reverse‑grating screen cleaner’s performance and reliability directly impact the efficiency and quality of wastewater treatment. At present, similar products on the market vary in specifications, performance, installation, and maintenance, and there is a lack of unified technical standards, which creates operational challenges for wastewater treatment plants. In response, the state has introduced a series of policies and regulations, including the Action Plan for Water Pollution Prevention and Control, to strengthen the development of urban wastewater treatment infrastructure and enhance treatment capacity.
Technological Innovation Highlights
The group standard “FHG‑Type Reverse‑Draw Grating Cleaner” specifies the basic requirements, manufacturing specifications, and electrical control criteria for grating cleaners, thereby ensuring the equipment’s quality and safety. It outlines the performance parameters of the grating cleaner—such as water depth, width, design flow rate, and bar‑clearance velocity—to guarantee that the equipment meets practical operational needs. The standard also defines corrosion‑protection treatments and coating processes, including rust‑preventive measures and specified coating thicknesses, to extend the service life of the equipment.
Equipment Workshop
Technological role
By establishing this standard, equipment performance and stability can be enhanced, wastewater treatment efficiency can be ensured, and the processes for equipment procurement, installation, and operational management can be streamlined, thereby reducing operating costs. This will also drive technological innovation and industrial upgrading in the mechanical bar screen industry, elevate the overall technical level of China’s wastewater treatment equipment, and play a positive role in advancing the environmental protection equipment sector.
At the review meeting site
After hearing a report from the standard‑drafting organization on the progress of drafting the standard, experts from Guangxi University for Nationalities, the Guangxi Standardization Association, Guangxi Beitou Environmental Protection and Water Services Group Co., Ltd., the Guangxi Society for Environmental Sciences, Guilun Environmental Technology Co., Ltd., and other institutions conducted a thorough review of the standard article by article and clause by clause. They unanimously concluded that the group standard “FHG‑Type Reverse‑Lifting Grating Cleaner” is comprehensive and possesses scientific rigor, cutting‑edge technology, and practical applicability. The promulgation and implementation of this standard are of great significance for standardizing the technical requirements of FHG-type reverse‑grappling bar screens and for advancing the high‑quality development of the environmental protection equipment industry.
