A phosphorus-free, low-nitrogen and biodegradable future
During operation, the membrane system is prone to contamination by calcium and magnesium ions, silicides, iron and manganese ions, microorganisms, etc., which leads to a decrease in membrane flux, an increase in pressure difference, and a reduction in desalination rate.
During operation, the membrane system is prone to contamination by calcium and magnesium ions, silicides, iron and manganese ions, microorganisms, etc., which leads to a decrease in membrane flux, an increase in pressure difference, and a reduction in desalination rate. The dedicated membrane scale inhibitor effectively inhibits the crystallization and deposition of insoluble salts on the membrane surface through dispersion and chelation, keeping the membrane channels unobstructed and extending the cleaning cycle. For different types of pollution, acidic, alkaline and biofilm-specific cleaning agents can gently and efficiently remove contaminants on the membrane surface, restore membrane performance, and at the same time reduce damage to the membrane material.
In the field of seawater desalination, salt-resistant membrane scale inhibitors can adapt to water with high salinity and hardness, ensuring the stable operation of the system and reducing water production costs. In electronic ultrapure water and power plant boiler feed water systems, high-purity membrane chemicals can prevent secondary pollution and ensure that the produced water quality meets the standards. In industrial wastewater reuse projects, the combination of membrane chemicals and membrane systems can increase the wastewater reuse rate to over 85%, achieving the recycling of water resources.
With the continuous expansion of the application scope of membrane technology, membrane chemicals are developing towards being green, phosphorus-free, low-nitrogen and biodegradable, reducing their impact on the environment. Meanwhile, the intelligent chemical dosing system is deeply integrated with the membrane process, achieving online monitoring, automatic dosing, and fault early warning, thereby enhancing the stability of system operation and the level of management refinement. In the future, with the collaborative innovation of membrane materials and membrane chemicals, membrane separation technology will play a greater role in the field of water treatment.
