Introduction to the reverse osmosis system of pure water equipment:
A complete reverse osmosis equipment system consists of pre- It is composed of the processing part, reverse osmosis host (membrane filtration part), post-processing part and system cleaning part.
Pretreatment part:
The pretreatment of reverse osmosis equipment often consists of quartz sand filter device, activated carbon device, and precision filter device. The main purpose is to remove sediment, rust, etc. contained in the raw water. Colloidal substances, suspended solids, pigments, odors, biochemical organic matter, reduce residual ammonia value in water and pesticide pollution and other harmful substances. If the content of calcium and magnesium ions in the raw water is high, a water softening device needs to be added. The main purpose is to protect the reverse osmosis membrane of the later stage from damage by large particles, thereby extending the service life of the reverse osmosis membrane.
Reverse osmosis host machine:
Mainly composed of booster pump, membrane shell, reverse osmosis membrane, control circuit, etc., it is the core part of the entire water treatment system. It determines the quality of the produced water. The most important thing also depends on this part. As long as the membrane model and booster pump model are properly selected, the reverse osmosis host's filtration capacity for salt in water can reach above
, and the conductivity of the effluent can be guaranteed to be within
(
degrees) .
Post-processing part:
Mainly to further process the pure water produced by the reverse osmosis main machine. If the subsequent process is connected to ion exchange or electrodeionization ()
equipment, Ultrapure water for industrial use can be produced. If it is used in a civilian direct drinking water process, it is often connected to a post-sterilization device, such as an ultraviolet germicidal lamp or an ozone generator, so that the water can be directly used.
Cleaning part:
In order to ensure the normal operation of the reverse osmosis equipment system and extend the service life of the reverse osmosis membrane elements, when the reverse osmosis equipment system has been running for a period of time, it is necessary to remove calcium carbonate scale and metal oxide scale in the water. , biological growth (bacteria, fungi, mold, etc.) and other substances require the system to be cleaned.
Pure water equipment installation steps
..
Place the pre-processor and reverse osmosis
pure water
host near the water source and power supply.
..
, filled with quartz sand
, activated carbon, softened resin
and other filter materials.
..
, connect the waterway: connect the raw water pump
water inlet to the water source, the pretreatment filter outlet to the host inlet, pretreatment
filtration
and the main unit are connected to the sewer with pipelines.
..
Circuit: First, connect the grounding wire to the ground reliably, and connect the supplied power cord to the electrical control box in the room.
..
, connect the water source and power supply, and operate according to the steps according to the requirements of the
Pretreatment Operation Instructions
, and the pretreatment debugging operation is completed.
..
When using this machine, turn the original water pump switch to the automatic position and turn on the shutdown switch. Connect the water source and power supply, and when the pressure at the multi-stage pump port reaches the set value of the pressure controller, the multi-stage pump will start working. After the multi-stage pump is started, adjust the system pressure to
. When starting up for the first time, the R membrane system should be manually flushed for several minutes.
