Stainless Steel Secondary Reverse Osmosis Water Treatment Equipment
Description:
1. The floor space is small, and the mixed bed and regeneration
device are omitted.
2. The produced water is continuous and stable, and the effluent
quality is high, while the water quality of the mixed bed will
become worse when the resin is near to failure; EDI device is a
continuous water purification process, so its product water quality
is stable, and the resistivity is generally 15M Ω, up to 18M Ω,
reaching the index of ultrapure water. The water purification
process of the mixed bed ion exchange facility is intermittent. The
product water quality is high just after regeneration, but poor
before the next regeneration.
3. Low operation cost, regeneration only consumes electricity, no
acid and alkali, saving material cost; The operation cost of EDI
device includes power consumption, water consumption, reagent cost,
equipment depreciation and other costs, saving acid and alkali
consumption, reclaimed water, wastewater treatment, sewage
discharge and other costs. In terms of power consumption, the EDI
device is about. 5kWh/t of water, and the mixed bed process is
about 0.35kWh/t of water. The cost of power consumption is
relatively economic for the power plant, which can be calculated
using the price of auxiliary power. In terms of water consumption,
EDI unit has a high water production rate and does not use recycled
water, so the operating cost in this respect is lower than that of
the mixed bed. As for the pharmaceutical cost and equipment
depreciation cost, there is little difference between them. In
general, the operating cost per ton of water of conventional mixed
bed is higher than that of EDI device. Therefore, the extra
investment cost of EDI devices can be completely recovered within a
few years.
4. The environmental protection benefit is significant, and the
operation safety is increased; EDI is an environment-friendly
technology, which does not require chemical regeneration of acid
and alkali, saves a lot of acid, alkali and cleaning water, and
greatly reduces labor intensity. More importantly, there is no
discharge of waste acid and alkali liquor. As a non chemical water
treatment system, it does not require the storage and treatment of
acid and alkali and no discharge of wastewater, so it has a special
attraction for new users.
