Electroplating wastewater include the pretreatment rinsing wastewater, plating rinsing wastewater. And the principal pollutants are heavy metal ion . 1.1 Up-to-standard discharge technology The emission of waste water which contains heavy metal ions such as Cr, Cu and Ni must meet the local requirements by adopting the means of Physical and Chemical Reaction + Sequencing Batch Precipitation + Ion Exchange + Compulsory Filtration to reach the standard. 1.2 Electroplating wastewater reuse technology Electroplating wastewater reuse technology means to add reclaimed water reuse system and reuse system on the basis of standardized discharge technology. The effluent can meet reclaimed water reuse standards(such as cleaning). 1.3 Electroplating wastewater zero-discharge technology MVR evaporator Working principle: MVR evaporator will increase the energy of secondary steam by using compressor, and will take advantage of the secondary steam with improved energy to recycle the potential heat of secondary steam. Specifically: Increase the pressure and temperature of the secondary steam generated by evaporator through the adiabatic compression in compressor, and after that, the steam will be fed into the heating chamber of evaporator (heat exchange system) as the heating steam, thus the potential heat of steam can be reused. The cold material will absorb the heat of non-condensable gas through preheating exchanger before being sent into evaporator, so the temperature of the cold material will increase, meanwhile, the condensate can be cooled by this material. This can further improve the utilization ratio of heat.

If you want to know more about our functional crystals, please do not hesitate to contact OST Photonics. What are Functional Crystals? A wide range of functional crystal materials is used in various optical applications. While optical glass is commonly used as a transparent material, different functional crystal materials, primarily monocrystalline materials, are required for diverse applications due to their unique functionalities: In contrast to glass, birefringent crystals can exhibit birefringence, which is a requirement for various types of polarizers, wave plates, birefringent tuners, and other optical components. Commonly used birefringent crystal materials include YVO4, �±-BBO, quartz, calcite and sapphire. The lattice symmetry of a crystal material is not too high (such as a triangular, quadrilateral, or single prism), and it can exhibit nonlinearity. Nonlinear crystals are primarily used for nonlinear frequency conversion but also find applications in optical modulators like the Pokel cell. A wide variety of functional crystal materials can be used as laser crystals, serving as host materials for laser-active dopants (rare earth ions or transition metal ions). They typically exhibit relatively high transition cross sections, small gain bandwidth, and good heat conduction compared to laser-active glasses. In general, they also allow for higher doping concentrations. In some cases, functional crystal materials are used in spectral regions where glass does not have a wide enough wavelength range and high transmittance. In particular, various materials such as zinc sulfide (ZnS), zinc selenide (ZnSe) and Sapphire (Al2O3) are used as infrared crystals, and other materials such as lithium fluoride (LiF), calcium fluoride (CaF2) and magnesium fluoride (MgF2) are used as ultraviolet crystals. Some functional crystal materials, such as terbium gallium garnet (TGG), exhibit the Faraday effect (polarization rotation caused by magnetic fields), and they can be utilized in devices like Faraday rotators and Faraday isolators.
Application Benchtop temperature chamber can meet certain quality standards and testing specifications ,for example: Daily necessities, cosmetics, electronic components, and medical products .� Most ideal designed for temperature and humidity testing of small samples and specimens used for research, development and quality control.� This dimension are very cute. customer can fit on a personal desk is the most consideration.If you need more models about our test equipment, please reference our chamber-testingï¼?.ï¼?com Feature: Our JOEO Benchtop Temperature Chamber's window is equipped with an anti-sweat electric heater device to prevent water vapor from condensing and water droplets, and high-brightness PL fluorescent lamps keep the interior of the box illuminated;Rectangular multi-layer glass viewing window, which can be used to observe the test items during the test.� With automatic-water supply system, it is convenient to supplement the water supply of the humidification barrel, and it can be recycled and used automatically.
