Hemodialysis reverse osmosis water treatment system

Hemodialysis reverse osmosis water treatment system

Firstly, let me explain what infiltration, osmotic pressure, and reverse osmosis are:

Penetration: The solvent (water molecules) spontaneously flows into one side of the concentrated solution (water molecules) through a semi permeable membrane (such as peritoneum, reverse osmosis). A semi permeable membrane only allows water molecules to pass through and prevents dissolved solids (salts) from passing through.

Osmotic pressure: During the process of permeation, the concentrated solution dilutes the water flow, and when the water flow is concentrated, the solution generates sufficient pressure to prevent the water from continuing to flow in, resulting in permeation equilibrium. In equilibrium, water flows uniformly through the semi permeable membrane, which is in a dynamic equilibrium state. The pressure at this point is called the osmotic pressure of the solution. Osmotic pressure is a characteristic of a solution that increases with the concentration of the solution.

When equipped with reverse osmosis devices, the number of dialysis machines, the reuse of water by dialyzers, and the reasonable speed of water reverse osmosis machines for future development should be considered. The water quality analysis report based on water pretreatment should be reasonably allocated, and the standard type and quantity of dialysis membrane water for reference selection and dosage should be selected.

The reverse osmosis water treatment system generally consists of reverse osmosis membrane components, pressure vessel shells, device frames, pressure pipelines, regulating control valves, high-pressure pumps, system control electrical devices, detection and control devices, alarm devices, disinfection devices, etc.

Centrifugal pump high-pressure pump is the main component of the reverse osmosis system, which provides stable and uninterrupted flow and appropriate pressure to the membrane components. It requires 1.6MPa for conventional composite membranes and 1.05MPa for ultra-low pressure composite membranes.

Reasonably select pipelines and valves, such as pressure resistant, non-toxic, corrosion-resistant, etc. Copper devices should not be used on the water side of the product, and sanitary fittings should be selected. The system should have disinfection equipment and safety facilities;

In addition, the reverse osmosis device should have: conductivity display records for inlet and product water, flow indication records for inlet, product water, and drainage, residual chlorine display for inlet and product water, pressure display records for inlet and high-pressure pump inlet and outlet, and product water, as well as inlet temperature and pH value display.
