120HOverview of large-scale reverse osmosis water treatment equipment:

Large scale reverse osmosis water treatment equipmentA water treatment equipment that uses reverse osmosis membrane separation technology to filter and remove impurity ions, bacteria, colloids and other substances in raw water. The general components of the equipment mainly include: booster pump, quartz sand filter, activated carbon filter, scale inhibition and dosing device, security filter, high-pressure pump, reverse osmosis device, and pure water pump. If applied to different industries, different water requirements, and different water sources, the process can be adjusted appropriately,RO reverse osmosisThe current application range of technology is very wide

III20T/HThe production process of large-scale reverse osmosis water treatment equipment:
Raw water tank → Raw water pump → Mechanical filter → Activated carbon filter (stainless steel) → Scale inhibitor dosing system → Precision filter → High pressure pump → Reverse osmosis host → Pure water tank → Water point;

4T/HCleaning of softened water device in large-scale reverse osmosis water treatment equipment

The working principle of the softener is ion exchange,ion exchangerThe characteristic of use is to frequently regenerate the resin. Pay attention to the following issues when using:

1. When the hardness of the effluent exceeds the standard (hardness requirement ≤ 0.03mmol/L), it must be stopped from use and regenerated;

2Cationic resinThe regeneration method is to soak the resin in salt water for about two hours, dry the salt water, and then rinse it back with clean water to continue using it;

5T/HIn large-scale reverse osmosis water treatment equipmentroPreservation methods for membrane components

1. Short term preservation

Suitable for stopping operation for 5-30 daysLarge scale reverse osmosis water treatment equipmentAt this time, the membrane element is still installed in the systempressure vesselIn the middle.

(1) Rinse with waterLarge scale reverse osmosis water treatment equipmentAt the same time, pay attention to removing the gas from the system;

(2) After filling the pressure vessel and related pipelines with water, close the relevant valves to prevent gas from entering the system;

(3) Rinse every 5 days according to the above method.

2. Long term disuse protection

(1) Cleaning membrane components in the system;

(2) Prepare disinfectant solution using reverse osmosis produced water and rinse with disinfectant solutionLarge scale reverse osmosis water treatment equipment；

(3) Fill with disinfectant solutionLarge scale reverse osmosis water treatment equipmentAfter that, close the relevant valves to keep the disinfectant in the system, and at this time, make sure the system is full;

(4) If the system temperature is below 27 degrees, a new sterilization solution should be used every 30 days for operation; If the temperature is above 27 degrees, the disinfectant should be replaced every 15 days;

(5) InLarge scale reverse osmosis water treatment equipmentBefore putting it back into use, rinse the system with low-pressure water for one hour, and then rinse the system with high-pressure water for 5-10 minutes; Regardless of whether it is low-pressure flushing or high-pressure flushing, all water discharge valves of the system should be fully opened. Before the system resumes normal operation, it should be checked and confirmed that the product water does not contain any fungicides.
