Product Introduction
Pretreatment system
Sand filter Also known as “Mechanical filter” or “Multi media filter” Composition: mainly composed of pressure vessel and Filter material composition. Particle size difference is laid in layers under pressure a filter bed is formed in the pressure vessel.
Activated carbon filter is composed the activated carbon filter is composed of pressure vessel and activated carbon filter material.
Softening filter is composed of ion exchange resin (multi sodium type), pressure vessel, salt tank and regeneration cleaning control mechanism.
Precision filter (or security filter) is composed of filter element (filter element with pore diameter ≤ 5 microns is recommended) and stainless steel pressure vessel.
Flocculant when the suspended solids content in the water source is high, adding a certain concentration of flocculant can further reduce the pollution index SDI. The mechanism is to destroy the electrical neutrality of colloid and make it flocculate and precipitate.
Antiscalant adding an appropriate amount of scale inhibitor into the RO inlet water can inhibit the scaling of minerals on the surface of reverse osmosis membrane (concentrated water side).
Deep treatment
The Reverse Osmosis device is an equipment to purify the saline water with the action of pressure difference of semi-permeable membrane. It is called reverse osmosis, as it is counter to natural penetration direction. Difference materials have different osmotic pressures.
The reverse osmosis can remove more than 97% of the soluble salt and above 99% of the colloid, microorganism, particles and organic materials, becoming the best first-choice choice equipment in the engineering of modern purified water, highly purified water and space water (super-purified water). The most highlighted features are low energy consumption, no pollution, simple technique, high-quality water and convenient operation and maintenance.
Terminal treatment
Ultraviolet disinfection nucleoproteins in microorganisms are denatured due to the absorption of broad-spectrum ultraviolet energy, causing metabolic disorders and loss of reproductive ability. When the irradiation dose increases to a certain amount, the microbial cells are destroyed and killed.
Ozone disinfection Ozone is a strong oxidant, and the sterilization process is a biochemical oxidation reaction.
Membrane Filtration System
Reverse Osmosis Equipment
RO is a technology of separating solutes and solvent from solution by the selection and interception of semi-permeable membranes under drive by pressure. This technology can be applied to water treatment process fo removal of contaminants, such as inorganic ions, bacteria viruses, organisms and colloids.
So far, RO is the most advanced, effective and energy- saving membrane separation technology in the world. It’s often used concurrently with front-end pretreatment system for easy operation, lower operating cost, non-pollution and easy maintenance and other advantages. Semi-permeable membrane plays the function of interception under the compression of high pressure pumps, and working effectively to remove the water contaminants such as solid solutes, organisms, colloids, microorganisms, bacteria etc. It’s wide range of application, active control, small area, low energy consumption, and high quality of output water.
Ultrafiltration Equipment
Ultrafiltration can intercept the macromolecular substances and impurities which are between 0.002 to 0.1 microns, ultrafiltration membranes allow the small molecular subtances and soluble total solids’ (inorganic salt) pass, while intercept the colloid, preteins, macromolecular organic matter, microorganism, and the operating pressure is general between 1-7 bar.
Nanofiltration Equipment
Nanofiltration is a new membrane filtration process, mostly used to deal with the lower total solids water, such as surface water and groundwater, and its purpose is to soften (remove the multi-mediated cations) and remove DBPs, such as natural organic matters and organic compounds.
In recent years, nanofiltrations are widely used in food processing, for instance the dairy processing and etc, which can reach the concentration standard and partially remove mineral deposits.
