Abstract

The invention discloses a manufacturing method of a reverse osmosis membrane element, which comprises the following steps: oppositely superposing two water inlet surfaces to form a water inlet flow channel; and winding the central pipe from the water inlet end of the water inlet flow channel along the water outlet surface, so that the reverse osmosis membrane forms a reverse osmosis unit. According to the manufacturing method of the reverse osmosis membrane element, the purity of the first cup of water is effectively improved, so that the user experience is improved, and the practicability ofthe water purification equipment is improved.

Description

technical field [0001] The invention relates to the field of reverse osmosis filter elements, in particular to a method for manufacturing a reverse osmosis membrane element. Background technique [0002] The existing water purification equipment mainly relies on the membrane filter element to filter the raw water. However, when the water purification equipment is in the standby state, there will be raw water, waste water and pure water in the membrane filter element at the same time. In front of the membrane, the pure water is behind the membrane of the membrane filter element, and the TDS values ​​of raw water and waste water are much higher than the TDS value of pure water. If the water purification equipment is in a standby state for a long time, the raw water and The ions in the wastewater diffuse into the pure water, thereby increasing the TDS value of the pure water. When the water purification equipment is turned on to obtain pure water next time, the TDS value of the...
