● Carefully remove the industrial reverse osmosis membrane from the package and check that the brine seal ring on the industrial reverse osmosis membrane or the small arrow on it is in the correct position and orientation.

drainage中文

Drainage systems can be different for stormwater and sewers, but sometimes both these inputs drain into the same underground drainage system. The advantage of having separate drainage systems is that stormwater runoff is not so dangerous that it has to be treated. This can be drained directly into water bodies. Water containing sewage and industrial wastes, on the other hand, can be extremely toxic. Therefore, they have to undergo at least a primary treatment before they can be let into water bodies.

drainage意思

The use of open drains is not a good option to carry wastewater even if the solids have been removed by the use of septic or interceptor tanks because people can easily come into contact with it. Moreover, since they are open any excess water can result in flooding. The only advantages of using open drains are in its convenience of construction and maintenance as it is easily accessible. This is why you can still see the use of open drains in rural areas. However, in densely populated urban areas, such a system will fail in its effectiveness.

● Push the RO membrane from the feed side to the retentate side until the first installed RO membrane is in firm contact with the retentate end plate.

ULP Series Ultra-low Pressure Industrial RO Membrane Elements are made of polyamide composite membrane materials, and operate at ultra-low pressure. The industrial RO membrane elements can achieve the required water production and high desalination rate under the ultra-low pressure condition. The ultra-low pressure RO membrane operating pressure is 2/3 times of that of the conventional composite membrane, thereby reducing the investment costs of related pumps, pipelines, containers and other equipment and the operating costs of the reverse osmosis system, and improving economic benefits. ULP series RO membrane elements are suitable for water sources with a salt content of less than 2000ppm, such as the desalination of surface water, groundwater, tap water and municipal water etc..

Sewage

● Install a thrust ring at the concentrate end of the pressure vessel to prevent the reverse osmosis membrane from being over squeezed and damaged.

● Repeat the above steps to connect reverse osmosis membranes to each pressure vessel and connect all external water inlets, concentrate and water generation pipes.

Soil

There are two uses for a drainage system as part of existing and developing urban systems or cities. Drainage systems are in place to remove the excess water in development. This could be floodwater, rainwater, and different kinds of runoff. Drainage systems are also in place to effectively remove wastewater, which is referred to as a sewer system.

Absorb

There are both closed and open drains in different areas. Closed drain forms a complex network underground. The primary refuse from individual areas is collected and transported to the main network, which finally goes to a treatment plant. An open drain is mostly used to collect wastewater that is not sewage. The use of open drains to dispose of sanitary waste is extremely unhygienic and unsafe. The use of open drains to a certain degree can be acceptable. However, any place with a collection of water breeds various disease-carrying pathogens.

● Push one end of the industrial reverse osmosis membrane without the brine seal through the inlet end of the pressure vessel until the membrane element is exposed about 30cm outside the inlet end of the pressure vessel. Lubricate the brine seal.

A drainage system is an arrangement to move liquids away from where they are not required for disposal in appropriate locations. A ‘drainage system’ can include anything from gutters and drains in houses to remove rainwater, stormwater systems to drain rainwater from roads into roadside drains and drainage systems to remove sewage from houses into municipal ‘sewers’ for disposal.

● When installing the end cap, carefully inspect the "O" ring of the component adapter, apply lubricant, then insert the adapter into the concentrate end plate and connect to the external pipe, to make the connection, the end plate must be carefully placed on the The purge end of the pressure vessel and align the concentrate end plate assembly with the assembly fitting. Press parallel to the pressure vessel.

Not having a proper drainage system in place will result in flooding of low-lying areas, thereby causing property damage and health risks. An effective drainage system is one that removes all excess water without causing inconveniences in terms of design. For example, in an area with many buildings like residences and shops, there cannot be open drains that flow through the areas.

● Take the second industrial reverse osmosis membrane out of the package again, make sure that the "O" ring on the permeate end of the membrane does not fall off, and align the end of the reverse osmosis membrane without the sealing ring with the first element (fix the first element Branch RO reverse osmosis membrane). Rotate to the right, the two marks on the end face become a straight line, when a click is heard, it means that the two membrane elements are fixed, the two membrane elements are fixed to the second push it into the pressure vessel . It is exposed about 30cm outside the inlet end of the pressure vessel, and other components are installed in the same way.
