Hebi Hongze Technology Co., Ltd.: A specialized manufacturer of aluminum sulfate without iron.
Deeply rooted in the chemical industry, we focus on the R&D and production of water treatment agents.
Hebi Hongze Technology Co., Ltd. was established in 2019 and is a modern enterprise specializing in the research, development, production, and sales of water treatment agents and related chemical products. The company is located in the Jijiashan Industrial Park, Heshan District, Hebi City, Henan Province, covering an area of over 54 mu. It has invested in a project to produce 100,000 tons of water treatment agents annually, which is being developed and constructed in two phases.
The company has a registered capital of RMB 10 million and paid-up capital of RMB 10 million, supported by state-of-the-art production facilities, a highly skilled technical team, and a rigorous quality management system. After years of development, Hongze Technology has established a comprehensive product portfolio centered on aluminum sulfate-based products, extending to a wide range of water treatment agents and chemical raw materials. The company provides stable, reliable product supply and technical support to customers across multiple industries nationwide.
Ferric-free aluminum sulfate: a high-purity product that meets the application requirements of multiple industries.
Ferric-free aluminum sulfate is one of Hongze Technology’s core products. Its chemical formula is Al₂(SO₄)₃·xH₂O, and it appears as white granules, flakes, or powder. It is readily soluble in water, and its aqueous solution is acidic. Compared with conventional aluminum sulfate, ferric-free aluminum sulfate undergoes a specialized processing procedure that reduces its iron content to an extremely low level—typically below 0.005%—while also significantly lowering the levels of other heavy metal impurities.
Main application areas of the product
Water treatment industry As a flocculant, it is widely used for the purification and treatment of drinking water, industrial water, and domestic wastewater. It effectively removes suspended solids, colloidal substances, organic matter, and certain heavy metal ions from water without introducing additional iron‑ion contamination, making it particularly well suited for applications with stringent water‑quality requirements.
Paper industry It is used as a sizing agent and retention aid for paper. When combined with rosin and other sizing agents, it forms a dense hydrophobic film on the surface of pulp fibers, enhancing the paper’s water resistance, ink‑set resistance, and fold endurance. Because it contains no iron ions, it prevents yellowing and spotting caused by iron contamination, making it widely employed in the production of writing paper, printing paper, and food‑grade packaging paper.
Food and Pharmaceutical Industries It can be used as a food additive (E520) and also as a pharmaceutical excipient or raw material in the manufacture of medicines.
Other fields It can also be used in multiple industries, including titanium dioxide post‑treatment, concrete waterproofing agents, foam fire‑extinguishing agents, oil and fat decolorizers, and wood preservatives.
Product Specifications and Quality Control
Hongze Technology’s iron-free aluminum sulfate is manufactured in strict accordance with the HG2225-2001 standard and is available in various alumina contents (15.8%, 16.5%, 17%, etc.). Customized production is also offered to meet specific customer specifications. The company has established a comprehensive quality‑control system, conducting rigorous inspections on every batch to ensure consistent and reliable product quality.
A comprehensive product portfolio and robust service capabilities
In addition to iron-free aluminum sulfate, Hongze Technology also manufactures and markets liquid iron-free aluminum sulfate, ammonium aluminum sulfate (ammonium alum), potassium aluminum sulfate (potassium alum), battery-grade aluminum sulfate, defluorination agents, magnesium sulfate, polyaluminum chloride, polyferric sulfate, and a variety of other products, thereby meeting the diverse needs of different customers.
The company boasts a dedicated sales and technical services team that provides customers with product selection assistance, usage guidance, and other technical support. In addition, the company holds qualifications for both goods import and export as well as technology import and export; its products are not only supplied to the domestic market but are also exported to numerous countries and regions.
Continuously driving innovation to support environmental sustainability.
As a company dedicated to the production of water treatment chemicals, Hongze Technology consistently adheres to the principles of green development, placing great emphasis on environmental protection and sustainable manufacturing. The company continuously optimizes its production processes, enhances resource efficiency, and minimizes pollutant emissions, striving to deliver more environmentally friendly water treatment solutions to its customers.
Looking ahead, Hebi Hongze Technology Co., Ltd. will continue to deepen its expertise in the chemical industry, increase investment in research and development, and consistently enhance product quality and service standards. The company is committed to becoming a leading domestic manufacturer of water treatment agents, contributing to China’s environmental protection efforts and industrial development.
