Process description
The process consists of the following parts: stacked filters, ultrafiltration system, scale inhibitor injection system, reverse osmosis membrane desalination system, EDI system.
Stacked filter
The role of the device to remove large impurities in the water, soft impurities, fibrous impurities, and effectively protect the ultrafiltration membrane unit. Filter selection of Israel ARKAL automatic backwashing disc filter. ARKAL company is the founder of the laminated filtration technology, thin plastic laminated sheet of a particular color on both sides of a large number of engraved with a certain micron size grooves. A series of laminated sheets of the same pattern are stacked on a specially designed inner support. When pressed together by spring and fluid pressure, the grooves between the laminations cross to create a deep filter unit with a series of unique filter channels, which is housed in a pressure- and corrosion-resistant cartridge to form a filter. During filtration, the filter stacks are compressed by springs and fluid pressure, and the greater the differential pressure, the stronger the compression force. This ensures self-locking and efficient filtration. The fluid flows from the outer edge through the grooves to the inner edge of the laminate and passes through 18-32 filtering points, resulting in a unique deep filtration. At the end of the filtration, the laminations are manually or hydraulically released from each other for manual cleaning or automatic backwashing.
The system filtration unit adopts SPIN KLIN automatic backwashing filter unit, SPIN KLIN automatic backwashing filter is the further play of the advantages of the stacked plate filter, SPIN KLIN filter and the general stacked plate filter is different from its patented design of the inner support, one-piece inner support has a set of springs, a piston, and three sets of backwash nozzles. They work together with other control systems to achieve high efficiency filtration and complete backwash.
In order to prevent the filter backwash on the ultrafiltration system operation, the system is set in the filter outlet pipe a FRP stabilizer tank, the volume of 200L, the maximum bearing pressure of 0.8Mpa.
Ultrafiltration system
Ultrafiltration equipment is the key part of the system pretreatment part of the ultrafiltration device, and ultrafiltration equipment for the heart of ultrafiltration membrane elements. The ultrafiltration membrane is composed of hydrophilic polyether maple hollow fiber, each ultrafiltration membrane element is composed of thousands of hollow fiber fiber bundles, each membrane length of 43 inches, the effective area of its filtration is 14m2. The molecular weight of its molecular weight retention of 5,000-100,000, the incoming water is from the hollow fiber of the internal flow into the water from the inside wall of the water through the outer wall (known as the pressure type) collected from the produced water discharges, the suspended solids, the suspended solids, the suspended solids, the suspended solids, the suspended solids, the suspended solids, the suspended solids, and so on, are collected from the produced water. The retained suspended solids, bacteria, macromolecular organic matter, colloids, etc. are accumulated on the inner surface of the fiber, after running for a period of time (about 4-8 hours), it is necessary to carry out backwashing, backwashing water for ultrafiltration of the water or a RO concentrate, but after several backwashing, the membrane may be adhered to the surface of the pollutants and micro-organisms that can not be easily flushed out, at this time, should be used with a certain concentration of chemicals in the water to carry out backwashing or chemical cleaning, generally the chemical is the same as the one that is used for the membrane. Or chemical cleaning, the general chemical for hydrochloric acid or sodium hydroxide or sodium hypochlorite.
Scale inhibitor dosing system
The agent is a dispersed hidden agent, it has the following effects:
l It is non-toxic, no foreign body shedding, stable chemical properties, can be chemically cleaned.
l Make the raw water Langelier LSI index from 0 to 2.6, in this range of calcium, magnesium hardness will not cause scaling in the membrane.
l Can prevent sulfate scaling, i.e. relatively increase the solubility of scaling substances in water, to prevent the harm of calcium sulfate and other substances on the membrane, especially BaSO4 and SrSO4 crystalline crystals on the membrane.
l It can also play a dispersing role for the iron colloid and fine particles blocking the membrane microporous.
l At the same time, the scale inhibitor is a composite organic matter, not dispersed to produce orthophosphate nutrients with bacterial nutrients, and will not pollute the environment after discharge, it is a green and environmentally friendly product. Dosing device including scale inhibitor solution box, the United States MILTON ROY dosing pump 1. Drug preparation is based on the drug solution tank occurs in the low liquid level alarm signal, by the operator to operate. By the dosing point configuration of the online flowmeter output 4-20mA signal to the metering pump, dosing and feed water flow rate proportional to automatically realize the adjustment of the dosage. At the same time, the pump itself has the ability to manually adjust the flow rate.
Reverse osmosis membrane desalination system
The pure water and the solution containing solutes with a semi-permeable membrane can only be separated by water, at this time, the pure water side of the water spontaneously through the semi-permeable membrane into the solution side, the solution side of the water surface rises, this phenomenon is osmosis. When the liquid level rises to a certain height, the pressure on both sides of the membrane to reach equilibrium, the solution side of the liquid level is no longer elevated, then, there is a pressure difference between the two sides of the membrane, known as the osmotic pressure . If the solution side with a pressure greater than the osmotic pressure, the water molecules in the solution will be squeezed to the pure water side, this process is exactly the opposite of osmosis, we call it reverse osmosis. We can see from the process of reverse osmosis that due to the pressure, the water molecules in the solution go into the pure water and the amount of pure water increases while the solution itself is concentrated.
The reverse osmosis membrane used in this equipment is a semi-permeable spiral membrane, when the raw water is sent to the reverse osmosis membrane at a certain pressure, the water through the tiny aperture on the membrane, the collection of pure water, while impurities in the water, such as soluble solids, organics, colloidal substances and bacteria, etc., are intercepted by the reverse osmosis membrane, the concentration of the intercepted liquid in the fluid and is removed. One-stage reverse osmosis can remove more than 97% of the dissolved solids in the raw water, and the two-stage equipment can remove more than 99% of the dissolved solids, more than 99% of the organic matter and colloid, and almost 100% of the bacteria. This dual-stage RO equipment is the use of the first stage of pure water into the second stage as raw water, so that the production of pure water to achieve a higher quality, in order to be used in the latter stage of EDI high-purity water production needs.
RO equipment is currently the world's water treatment equipment in the production of pure water, one of the most advanced equipment, its low operating costs, economic, easy to operate, reliable operation, is the user's first choice for the production of pure water equipment. This system of two-stage reverse osmosis equipment water production capacity of 45 tons / hour. The production capacity of the equipment is in the raw water at 25 ℃, the value of standard production conditions.
