How to inspect RO system for first time use?
1, from the pretreatment to reverse osmosis device all the equipment, piping, dosing systems and other materials to meet the requirements of corrosion;
2, all piping and equipment corrosion and daily operation and chemical cleaning when the pH range compatible;
3, all of the pretreatment system has been backwashing or cleaning and in a clean state;
4, the security filter installed a new clean filter;
5, the security filter must be no surfactant, lubricant, fabric;
6, the water supply pipeline has been washed, usually in the high-pressure pump and RO system before the completion of the connection; to confirm all the dust, grease, lubricants, metal residues and so have been removed from the pipeline installation;
7, the location of the drug point is correct, dosing system in the operating state;
8, dosing on the correct installation of the relevant valve;
9, the chemical into the RO system before the right mix;
10, dosing metering pump shutdown or drug to ensure that the RO system to stop the chain;
11, RO system to stop when the system shut down dosing system;
12, pretreatment if the use of chlorine and other oxidizing agents, to ensure that the use of the relevant measures to remove residual chlorine;
13, configure the relevant instrument is sufficient to monitor the system operating parameters and standardization;
14, the relevant instrument has been installed, calibration;
15, the system installed a pressure relief valve and in the correct set position;
16, any time the water pressure will not exceed the water or concentrated water pressure 0.7bar;
17, all the chain, delay and alarm installation is correct and tested;
18, to ensure that each pressure vessel can be sampled;
19, to ensure that the water, water, concentrated water for sampling;
20, the pressure vessel and the cleaning pipeline is connected correctly;
21, all the pressure vessel is safely secured to the RO bracket;
22, all the pressure vessel has been completed to fill the membrane components, the correct and safe installation of the pressure vessel cover;
23, safe and correctly connected to all the pressure vessel, in particular, check the clamp junction and pressure vessel end seal;
24, water outlet valve open;
25, before the water into the RO and the water can be discharged directly;
26, open the concentrated water control valve.
