Reverse osmosis pure water equipment

It is an integrated technology that combines microfiltration, adsorption, ultrafiltration, reverse osmosis, ultraviolet and ultra-purification,A device that directly converts tap water into ultrapure water. The core component of reverse osmosis pure water unit is reverse osmosisRO"Membrane" .

1.Select reverse osmosis membranes(ROmembrane)Pure water is prepared by using the current reverse osmosis technology process in the world;

2.Multi-stage filtration comprehensively leverages the effective functions of each treatment unit to remove sediment, suspended solids, colloids, organic matter, heavy metals, soluble solids, viruses, pyrogens and other harmful substances from the raw water, while retaining only water molecules

3.The stainless steel multistage pump is adopted, which features low noise, high efficiency, long service life and stable and reliable operation;

4.The pre-treated filter material can be replaced.

5.The water production process is automatically controlled. The machine stops when the raw water is short of water. During operation, it has low water pressure protection and stops when the water storage tank is full.[1]

The principle of reverse osmosis

A film that is selective for the substances passing through is called a semi-permeable membrane. Generally, films that can only allow solvents to pass through but not solutes are regarded as ideal semi-permeable membranes. When the same volume of dilute solution and concentrated solution are placed on both sides of a container respectively, separated by a semi-permeable membrane, the solvent in the dilute solution will naturally pass through the semi-permeable membrane and flow towards the concentrated solution side. The liquid level on the concentrated solution side will be higher than that on the dilute solution side by a certain height, forming a pressure difference and reaching an osmotic equilibrium state. This pressure difference is called osmotic pressure. The magnitude of osmotic pressure is determined by the type, concentration and temperature of the concentrated solution, and is independent of the properties of the semi-permeable membrane. When a pressure greater than the osmotic pressure is applied to the concentrated solution side, the solvent in the concentrated solution will flow towards the dilute solution. The direction of this solvent flow is opposite to the original osmosis direction. This process is called reverse osmosis.

Pretreatment of reverse osmosis pure water equipment

Including: raw water tank, raw water pump, multi-media filter, softener, etc.

The main issues to be addressed are as follows

1Prevent organic pollution;

2Prevent clogging by colloidal substances and suspended solid particles;

3Prevent oxidative damage to the membrane caused by oxidizing substances; This can ensure the stable operation and normal service life of the reverse osmosis device.

4Prevent scaling on the reverse osmosis membrane surfaceCaCO3,CaSO4,SrSO4,CaF2,SiO2Iron, aluminum oxides and other substances are deposited on the film surface
