Reverse osmosis system

In the process of introducing the membrane system, users pay more attention to the design of the process, and many problems have arisen in the process of use:

   Incomplete pretreatment system
   System selection is inappropriate
   Biological contamination of influent
   Membrane system fouling
   The system uses a large amount of reagents and frequent cleaning

Shenying Environmental Protection Reverse Osmosis Solution
Shenying Environmental Protection has the most senior expert team in the industry and has many years of extremely rich experience. We will customize the plan for you according to your operation and the composition of the water you use. Our RO plan helps you extend the life of the membrane, increase productivity and achieve repeatable results, reduce unplanned downtime, and improve the efficiency of pumping equipment. Focus on factory operations.

Pretreatment
RO system has specific requirements for the pretreatment of raw water. Reasonable pretreatment of raw water becomes the key to the success of the system.
When the insoluble salts are continuously concentrated in the membrane element and exceed its solubility limit, they will scale on the reverse osmosis or nanofiltration membrane. Due to water shortage and environmental impact, a reverse osmosis concentrated water recovery system is often installed to increase the recovery rate. Therefore, it is necessary to adopt well-designed and well-considered structural control measures to prevent the slightly soluble salt from exceeding its solubility to cause precipitation and scaling.
Microbes enter the reverse osmosis system and find soluble organic nutrients in the water. These organic nutrients are concentrated on the surface along with the reverse osmosis process to form a biofilm. Biological fouling of membrane elements will seriously affect the performance of the reverse osmosis system. There will be a rapid increase in the pressure difference between the inlet and the concentrated water, and sometimes even the water-producing side of the membrane elements will also appear biological fouling. Therefore, the control of microorganisms is also the main task of the pretreatment process.
Shenying Environmental Protection can provide you with efficient scale inhibitors and fungicides.
SINE-225HE is a high-efficiency scale inhibitor and dispersant, especially suitable for water with high content of metal oxides, silicon and scale-causing salts. It has high scale inhibitory efficiency and does not occur with residual coagulants or aluminum-rich and iron-rich silicon compounds. Coagulates to form insoluble polymers.
SINE-40NP is an efficient scale inhibitor and dispersant, especially suitable for reverse osmosis systems with high barium and strontium content in feed water, and serious scaling tendency of barium sulfate and strontium sulfate. It can effectively prevent the occurrence of fouling in a wide concentration range of fouling substances.
SINE-88 is a non-oxidizing bactericide, used in reverse osmosis systems plagued by biological pollution, and suitable for aromatic polyamide membranes and acetic acid membranes used. It is effective against bacteria, fungi, yeasts, blue-green bacteria, etc. The reproduction of microorganisms and their biofilms are greatly reduced between the surface of the reverse osmosis membrane and the water inlet channel. It can be quickly degraded into relatively non-toxic products, and its main degradation method is to react quickly with nucleophilic substances or organic substances in various water quality.

Cleaning plan
The cleaning of the RO system is a technically demanding job, requiring the selected agent to be stable and not damage the membrane. After decades of exploration and cooperation with relevant universities, the technicians of Shenying Environmental Protection have developed high-efficiency cleaning agents suitable for membranes of different materials, which can effectively extend the service life of the membranes. According to the characteristics of the cleaning agents, they are equipped with special offline cleaning. The equipment has been successfully applied in hundreds of factories.
Shenying Environmental Protection provides RO system online and offline cleaning. Selected according to site conditions.
