Useful Hard Water Treatment

April 23, 2010 by Leave a Comment

　　Hard water is the more soluble mineral constituents of water, especially calcium and magnesium. Hard water does not cause direct harm to health, but it will bring many problems, such as apparatus on furring water, soap and washing detergents to reduce the efficiency of such. Will soften hard water to avoid the deposition of scale there are many ways, frequently used methods are:

　　1) the ion exchange method: the use of specific ion exchange resins, sodium ions will displace calcium and magnesium in water, due to the high solubility of sodium, so we avoid the increase of temperature caused by scale build situation. This method is the most commonly used standard method. Main advantages: stable and accurate results, process maturity. Hardness can be reduced to 0.

　　2) Lime: adding lime to water is mainly used to handle large flows of high hard water, hardness can only be reduced to a certain extent.

　　3) Electricity and Magnetism method: use in the water with some electric or magnetic fields to alter the characteristics of ions, thus changing the calcium carbonate (magnesium carbonate) and sediment deposition rate of the physical characteristics of the time to prevent the formation of hard scale. Are used for business (such as central air conditioning, etc.) cooling water treatment, not for industrial production and boiler feed water treatment.

　　4) Canada Drugs Aid method: the water by adding specific inhibitors, calcium and magnesium ions can change the binding properties of carbonate ions, so that can not scale precipitation, deposition.

　　Water treatment is an integrated energy-intensive technology.

　　Water treatment is high energy consumption, high operating costs of technology. Can solve the problem of energy consumption of the water plant, a reasonable distribution of energy has become a water treatment plant decision good or bad running efficiency a key factor.

　　Effluent from the pollution source, which with the total amount or concentration of pollutants higher emission standards or fail to adapt to the environment capacity requirements, thereby reducing water quality and functional goals. Therefore, this place is the water treatment plant. Generally divided into urban sewerage treatment plants and water treatment plants dist

ributed sources. Treatment plant process flow is a variety of common or unique combination of optimal water treatment methods, including physical, chemical and biological methods. Depth from the treatment, the water treatment plant can be primary, secondary, tertiary or advanced tr

eatment process. Water treatment plant design includes a variety of structures, ancillary buildings, the pipeline of plane and elevation, and road design,

 green, channel integration, factory water supply and drainage, sludge disposal

 and treatment systems management and automation designed to

 ensure that water treatment plant treatment efficiency and stability to meet the design requirements, to facilitate operation and management, advanced technology, investment and other operating costs of provincial requirements.

Sponge iron oxygen scavenger

April 23, 2010 by Leave a Comment

　　Room temperature, the sponge iron oxygen scavenger, is an environmentally friendly water treatment media. Room temperature, the water treatment industry can achieve the desired effect. Sponge iron deoxidants facilities with less capital investment and use, simple maintenance, transportation costs low, oxygen removal effect of a good advantage.

　　 As a kind of water treatment chemicals, Sponge iron oxygen scavenger can be widely used in boiler and recycled water equipment corrosion, is a highly cost-effective energy-saving products.

　　Principles of sponge iron for the oxygen removal deoxidants: The great surface area of sponge iron for the filter, when water containing dissolved oxygen through the sponge, the sponge iron and oxygen in water hygiene and thorough oxidation occurred. Reaction product is insoluble in water, soft floc, when the reaction products accumulated to a certain extent, it can drain through the backwash, back to the initial oxygen removal capacity.
