But the large systems are difficult to maintain an absolute vacuum. This is not due to poor welding, and leak occurred mostly in the flange joints. As the aging of sealing materials, and even contact with the atmosphere of the small joints, are due to CO2 into the air leakage into the water system to lower pH values, causing corrosion.

　　System material is mostly carbon, so the system over the metal oxide corrosion products, of which the most iron corrosion products. Corrosion rate is not normal operation, but the infrastructure at the unit stage, the shutdown period, the start to protect properly, do not rinse the net, did not use dematerialized water rinse and load changes and other factors exacerbated the erosion. When the boiler feed water control is not operating at that time, will bring a number of soluble salts, when the hydrophobic of untreated back when the system will cause some pollution.

　　Therefore, the primary task of condensation water is removed metal corrosion products, silicon rubber, suspended impurities, should also remove soluble salts, this setting should be considered Condensate Treatment Unit. Should normally be under the specific circumstances of the project, such as the unit parameters, boiler type, hydraulic conditions and water quality requirements of units to be determined.

　　Biological wastewater treatment systems are mainly to remove dissolved oxygen in wastewater pollutants, chemical pollutants, the suspended solid pollutants, heavy metals and other pollutants and the senses, and adjust PH value.

　　The work scope of the Biological wastewater treatment system:

　　Sewage treatment system to discharge water mains water points, the starting point only. That regulate pools, PS fluidized bed, clean pool, sludge well, automation control devices. One regulation pool, clear pool, sludge wells constructed of reinforced concrete, fluidized bed by the fluidized bed tank, automatic control unit.

　　1) Reduce operating costs, simplifying operational procedures. Directly into the water need to be able to use sterile

　　2) Sterilization effect is obvious, lasting, and stable

　　3) On the raw water without any effect

　　4) Does not produce any harmful ingredients: only residual water and oxygen

　　Desalination Methods

　　1) distillation

　　2) freezing

　　3) RO

　　4) Solar Energy Law

　　5) low-temperature multi-effect

　　6) Multi-Stage Flash

　　7) pressure steam distillation

　　8) The flow of adsorption capacitance

　　1) Chlorine Disinfection

　　Chlorine disinfection is mainly through the oxidation of hypochlorite to kill bacteria, sodium hypochlorite is a small neutral molecule, can spread to the negatively charged surface bacteriological, bacteriological through the cell wall of bacteria through to the inside, and from oxidation, destruction of bacteria bacterial enzyme system Reship death, but for water, viruses, parasites kill the eggs less effective.

　　2) Ozone

　　Ozone oxidation and disinfection mechanisms, including direct indirect oxidation of free radicals, and chlorine and chlorine dioxide as the structure of micro-organisms through oxidative damage, to achieve the purpose of disinfection.

　　3) Chlorine dioxide

　　Chlorine dioxide disinfection mechanism is the oxidation can be better to kill bacteria, viruses, and does not produce damage on the plants and animals, sterilization lasted longer, the affected small, can be deodorant, to color.

　　4) Chloramines

　　Chloramines disinfection is the chlorine derivatives of disinfection methods, due to chloramines disinfection is slow, and it can not be as basic disinfectant, once disabled.

　　5) UV disinfection

　　The mechanism of UV disinfection is a certain dose of UV radiation can damage the structure of biological cells, by damaging the genetic material and biological to kill aquatic life, so as to achieve the purpose of water purification.

　　The filtered water should be disinfected with chlorine disinfectants. Inorganic substances that produce the smell of it, it can be oxidized thoroughly disinfected, the living natural material such as algae, bacteria, it can penetrate the cell wall; oxidation of the enzyme system (enzyme biological catalyst) lost its activity and life activity of bacteria killed by the barrier.

　　First, disinfect the water.

　　According to Secondary water supply system the characteristics of alternative disinfectant dosing point or high water tank underground cistern in two ways. Dosing underground cistern, disinfectants and water mix, while ensuring high quality water tanks. Directly adding water tank in the high dosage of less time, but the underground disinfection tank for long periods of the breeding of fungi and algae will be required to disinfected regularly cleaned.

　　Second, the high water tank and underground cistern sterilization:

　　In accordance with the relevant provisions, the owners need to periodically high water tank and underground cistern for disinfection. Disinfection methods can be used or high-pressure water gun immersion washing method, manual cleaning method.

　　Water enters the ship through the pipeline system before the marine life to prevent the device, to prevent marine life of the equipment of the ship.

　　Ballast water by pumping ballast to each ballast tank.

　　Also between each ballast tank ballast water pipeline system by the ballast pump each other through the transmission to adjust the ballast of ships.

　　Some ground water contains a variety of corrosive chemical composition, often using equipment geothermal serious corrosion damage, direct impact on equipment life. There are high salinity of ground water, using the temperature lower, which will dissolve some solid materials rather than saturation scale generated in the use of the system, causing equipment and pipeline blockage.

　　Therefore, the use of geothermal water should generally be based on water conditions and use for the corresponding processing; the equipment is kept in good condition and prolongs life.

　　Simple Home Solutions can improve your water pH, you can of soda ash or sodium hydroxide injection system to improve pH. This will increase the alkalinity of water.
