Reverse Osmosis Water Treatment

May 21, 2010 by Leave a Comment

　　Reverse osmosis water treatment is a pressure difference to drive a membrane separation technology, with a separate high, no phase change, simple and efficient characteristics. Reverse osmosis membrane “pore” has little to nanometer (1nm = 10-9m), the scanning electron microscope can not see the surface of any “filter” hole. Higher than the osmotic pressure in the operation of raw water pressure, water molecules can be reverse osmosis through semi-permeable RO membrane, production of pure water, while a large number of inorganic ions in raw water, organic matter, colloids, microorganisms, such as being the original RO membrane heat retention.

　　Reverse osmosis water treatment equipment is usually raw water pretreatment system, reverse osmosis purification systems, ultra-purified processing system composed of three parts. The main purpose of preprocessing is to make raw water to reverse osmosis membrane separation component of the water required to ensure the stable operation of reverse osmosis purification system. Reverse osmosis membrane system is a one-time 98% of raw water to remove ions, organics, and 100% of micro-organisms (in theory) the most cost-effective means of purification. Ultra-purification treatment system integration technology through a variety of reverse osmosis pure water to further remove the remaining trace ions, organic matter and other impurities in order to meet water quality objectives for different uses of the final requirements.

　　Pretreatment of reverse osmosis water treatment equipment systems usually polypropylene fiber (PP) filters and activated carbon (AC) filter form. Higher on the hardness of raw water softening resins need to install filters. PP water filter can effectively remove the original machinery of more than 5μm particle impurities, and the large jelly rust pollutants, such as protection of the follow-up filter, which is characterized by large pollutant, low price. AC carbon filter can be efficiently adsorbed chlorine and some organic matter in raw water, colloid, the protection of polyamide reverse osmosis composite membrane from chlorine oxidation. Softening resin can be removed most of the raw water calcium and magnesium ions to prevent scale buildup in follow-up RO membrane surface, improve water recovery.

Water Treatment Systems Residential

May 21, 2010 by Leave a Comment

　　The main problem facing the residential water

　　1)Muddy

　　As the municipal water supply network complexity, ancient or pipes of different materials, coupled with long-term corrosion or external pressure caused by the transmission pipeline damaged in varying degrees, so that the external impurities invasive tube. The water quality of water plant production is the standard completely, but in the transportation would be a lot of rust, sediment, suspended solids and flock into the pipeline, so that color turbidity, likely to cause secondary pollution of water. Water odor, and it will lead to pipeline blockage and water damage to the equipment.

　　2) Corrosion:

　　Corrosion is a water pipe or water-metal materials used in electrochemical processes in the water generated. When the water’s PH value is too low, the water has dissolved oxygen, water temperature or water conductive material will increase the water corrosive. PH value is too low in the water when it contacts the corrosion of metal compounds. Corrosion of metal surfaces is usually a layer of hydrogen will prevent continued corrosion protection film, but the oxygen will result in removal of this layer of hydrogen membrane corrosion to continue.

　　Therefore, the establishment of residential water treatment is necessary.

　　As for how to build residential water treatment, I will next time I will introduce. Welcome comments and suggestions.

Alum Water Treatment

May 19, 2010 by 1 Comment

　　Alum dissolves in water ionization can produce Al3 +, Al3 + and hydropower generated from the combination of OH ˉ generated aluminum hydroxide, aluminum hydroxide, colloidal particles with a positive charge, with negatively charged sand particles encounter each other was in charge and .Loss of charge particles, they will quickly coalesce together, the more particles larger end, and finally went to the bottom. This becomes clear clean water.

　　But the alum containing aluminum ions, alum treated water; the aluminum element can remain in the water. The aluminum does not belong to the trace elements necessary for the body, so excessive intake of aluminum element is harmful to human body. High content of aluminum element in the human body, it will affect the absorption of phosphorus.

　　In recent years, we also found that the emergence of Alzheimer’s disease and usually have too many elements in the aluminum intake. Using alum or other aluminum salts for purifying agent, also increases the water content of aluminum, so that people’s health is threatened.

　　In one word, healthy people occasionally a small amount of alum intake no big problem, but the adverse long-term consumption on health.
