Water treatment system
Introduction to the system
Water supply treatment composes of water for beverage foods
processing, water for electronic medicine and water for industry.
The water sources for water supply treatment compose of surface
water and under ground water. Surface water is also named as over
ground water and refers water in the river, lake and reservoir, and
features relatively salt content and hardness, water quality is
unstable and has big changes according to the season. Under ground
water means the water in deep well which is excavated manually, and
features more salt with stable water quality which won’t change
according to the season.
Introduction to Water treatment system
The technology a set of water treatment system uses depends on
water quality and purpose of water use. The adopted technologies
can basically be divided into pre-treatment system, depth treatment
system and terminal treatment system. Pretreatment system includes
media filter, active carbon filter, softener, iron and manganese
filter, ultra-filtration, micro-filtration, etc; advanced treatment
includes membrane method treatment and ion exchange; aftertreatment
system includes sterilization and ion exchange, etc.
Pretreatment system
Pretreatment system refers to using mechanical filtration,
absorption and coagulation to remove soap grains, colloid,
suspended substances, free residual chlorine and organic as much as
possible and lowering turbidity, colority, stink and hardness of
influent water to guarantee pretreated water meets the requirements
of depth salt-removing system.
Main Features:
Reasonable equipment structure, high treatment capacity;
Simple operation, automatic or manual operation is available
according to the actual situation;
All materials are quality stainless steel or carbon steel with
rubber.
Less spare parts, simple replacement.
Advanced treatment system
Ion exchange technology was adopted in depth treatment system in
China in early days. Because ion exchange needs acid-alkali
reclaiming treatment after a period of use, its reclaiming solution
is apt to pollute the environment after it’s discharged and the
maintenance cost is relatively high. Membrane method treatment
matured at technology is more widely employed now. Membrane method
treatment includes ultra-filtration, reverse osmosis and ion
filtration. Ultra-filtration is generally used in pretreatment
instead of depth treatment system. Reverse osmosis primarily
removes salt, metal ion and microbe in water to guarantee final
effluent water is qualified for the influent water requirements of
terminal treatment system.
Main Features: simple operation, convenient maintenance;
Automatic or manual working.
Water discharged from the system won’t cause any pollution to the
environment;
Compared with traditional salt removal equipments such as
electrodialysis and compound machine, it doesn’t need acid and
alkali regeneration with low cost in maintenance and low
occupation.
Terminal treatment system
According to end water, terminal treatment system can be roughly
divided into two types: one is preparations of drinking water and
the other is preparations of ultrapure water. After treatment
system for drinking water mainly uses ozone for sterilization.
Ozone is extremely strong oxidant with the function of
high-efficiency and sterilization. Meanwhile, the product of ozone
reaction is oxygen whose performance is better than that of
chlorine ultraviolet ray as a high-efficient oxidant without second
pollution. It is exactly this characteristic of ozone that has been
widely used in water treatment system extensively during recent
decades. Terminal treatment system for ultrapure water mainly uses
the most advanced technology of EDI, short for
electro-deionization, or mixed resin bed to further remove various
kinds of ion in water. EDI utilizes mixed ion exchange resins to
absorb anion and cation in supplied water and meanwhile the
absorbed ion is affected by direct current voltage to reclaim
resins continually in course of operation with the help of removing
by anion and cation Mixed resin bed also utilizes anion and cation
exchange resins to remove salt in water to a certain degree and
then carries on reclaiming with the help of acid and alkali.
Utilization-use-preparations means are often needed to keep the
system’s incessant water effluence.
Main Features:
Simple operation, convenient maintenance, it can continuously
output water without spare parts;
Compared with traditional equipment, it has small size and low
maintenance cost;
Automatic or manual working.
Water discharged from the system won’t cause any pollution to the
environment;
Electrical controlled system:
Electrically controlled design for water treatment abandons
traditional intermediate relay and time relay control methods and
selects mature programmable controller(PLC ) to carry on logic
control,. It adopts PLF of famous brands such as Siemens S7 series,
Mitsubishi FX series and ABLogix**0 series and network control such
as PPI, MPI, Profibus and CClink. It maximizes the guarantee of
system dependability and security and can also realize remote
monitoring.
In choosing low-voltage electric apparatus, Tech-long always
selects standard parts of ABB, TE Schneider and Muller, Siemens
low-voltage apparatus and selects Mitsubishi, Denver and ABB
converter according to the site technological requirements or
special project requirements. Siemens, ABB or Denver soft starter
expands technological flexibility greatly and gives play to the
greatest potential of equipment in electrical control of high power
or technologically key equipment.
In ergonomic operation, Tech-Long always selects stainless steel
electric cabinet and Boanerges electric fan matched with ABB, TE
Schneider or Muller snap fastener and contact switch and sometimes
matched with advanced and reliable GP Proface, Siemens TP/OP or AB
series human-machine touch-interface (HMI) according to the needs
of project to demonstrate the operation of equipment vertically and
rapidly and have the order of operator transmitted to PLC control
system in time
