I. Overview

Stainless steel membrane housing, also known as membrane pressure vessels, is a supporting product for reverse osmosis, sodium filtration, ultrafiltration and other devices. The shell is made of304Made of stainless steel tubes or wire-wound fiberglass reinforced plastic, the membrane housing is polished both inside and out.

Ii. Main Technical Features

●Pressure resistance2.0～2.5MPa

●Water inlet methods: Water inlet from both ends and from both sides

●Structure: Standard spare parts, easy and quick disassembly

●Sealing performance: Passed pressure resistance test

●The organizational structures at both ends: clamp type, card type, and internal spring type.

1.It mainly depends on the designer's requirements. The arrangement of the membrane and the requirements for the sections are different. According to the different angles of the inlet and outlet, it can be classified as:0Degree90Degree, and180There are three types of pressure resistance. In terms of pressure resistance theory alone, side-inlet water is better, but it increases the probability of water leakage in pressure vessels.

2.8The ratio of the flow rate and pressure of the membrane to water4"ROThe membrane is much larger. If two openings are made at the end of the membrane housing, it will reduce the pressure resistance of the end face and also add a lot of trouble in installation

3. The main issue is still the flow rate of the concentrated water, as the design for a large water recovery rate of a single membrane element is16%In order to improve the utilization rate of water, multiple membranes are connected in series to complete the task4"Inch"RO The pressure drop of the membrane is higher than8The pressure drop of the inch membrane is much larger, so the number of series connections cannot be too many. The specific number of series connections still depends on the water quality conditions and design parameters. In addition, the selection of high-pressure pumps also needs to be considered.

Its surface is mirror-polished and it has an attractive appearance. It is widely applied in various water treatment projects, pharmaceuticals, electronics, chemical and other industries.
