In recent years, as a result of agricultural activity and the influence that discharge contamination, the content of nitric acid salt in fountainhead of partial the earth's surface appears to increase a current apparently, become groundwater and one of heat issues that drinking water domain pays close attention to. To solve this one problem, kehaisai divided sex of the innovation in project of nitric acid salt to use ion exchange law to come in some groundwater the nitric acid salt in purify water.
This project handles water to measure 70m³/h, content of salt of raw water nitric acid is 22mg/l, the target is nitric acid salt falls to 20mg/l the following. Division sea thinks of technical group to be based on national level requirement, applied ability to get the technology of special type colophony that sulfate, chloric ion is disturbed and implements root of alternative adsorptive nitric acid, used the two place fountainhead, run mode that uses one equipment, made sure water quality amounts to mark not only, what still realized frequency conversion water supply is efficient run mode.
Colophony of groovy anion exchange suffers be confined to to the purify effect of nitric acid salt its are right of sulfate alternative preferential, bring about colophony second birth easily frequent, water quality giving water is not stable wait for a problem. Kehaisai is aimed at this one pain spot, chose Tulsimer®A-62MP to divide colophony of special type of nitric acid salt, this kind of colophony has the characteristic of salt of first exchange nitric acid, can promote pair of nitric acid effectively alternative adsorptive capability of salt, although be in the water that contains sulfate also salt of can preferential adsorptive nitric acid, do not suffer sulfate effect, make thereby its can better the nitric acid salt in purify water.
The course is custom-built the design that change and debug, the project checks and accept a result to show, content of nitric acid salt is reduced successfully from original 22mg/l to not check gives a level, far the 20mg/l target under project set.
Division sea thinks of the Tulsimer®A-62MP that technical group uses in the project to have the following advantage except colophony of nitric acid salt:
1, processing nicety is tall: By right of its high accuracy handles ability, a-62MP divides colophony of nitric acid salt to be able to fall the stability of total nitrogen content in liquid waste to 1ppm, stability obtains surface water requirement of 3 kinds of water standard.
2, adsorptive amount is large: Have good adsorptive performance, to nitric acid salt (with N plan) saturated and adsorptive capacity exceeds 10g/l, ensured the effect of purify of the deepness in handling a process.
3, alternative preferential, interference rejection sex is strong: This colophony is peculiar the alternative adsorptive function that is aimed at nitric acid salt, although be in the complex water that contains sulfate also salt of nitric acid of can first exchange, avoided the sulfate effect to efficiency of purify of nitric acid salt effectively.
4, use safety, apply extensively: Regard food as material, the deepness purify that Tulsimer®A-62MP colophony applies to nitrogen of salt of the nitric acid in a variety of fountainhead such as drinking water, groundwater, mineral water extensively, safeguard waters safety and character.
5, condense than optimizing: Can deepness handles low density liquid waste, compare a design through condensing efficiently, waste water of salt of nitric acid of low density of success broken solution tackles the trade difficult problem with big difficulty.
6, automation rate is high: Use module component form, the automation that implemented operation flow and simple and easy change, the moving efficiency that promoted whole the system greatly and safeguard convenient quality.
Kehaisai eliminates the successful practice on project of nitric acid salt in groundwater, showed division sea to consider the technical actual strength in water treatment domain and innovation ability not only, more solve nitric acid salt to exceeded mark issue to offer economy, efficient and the technical method that can last, strong the safety that ensured dweller drinking water and health.
