Two Bed Demineralizers

Steel Tank Two-Bed Demineralizer
The TBS-Series is designed to remove
cations and anions (minerals) from water.
TBS-Series systems can produce water
with an effluent quality of 10 to 20
micromhos-cm, equivalent to a sodium
content of 2 to 5 ppm as CaCO3 and a
silica level of 0.1 ppm as CaCO3.
Vessels
TBS-Series vessels are constructed of high quality carbon steel
and have a bolt and yoke manway in the top head. This
permits the loading of media and inspection of internals
without disturbing main piping. A 3" diameter media removal
pad flange is provided in the lower side sheet. Vessels include
structural legs.
Distribution
TBS-Series vessels are provided with separate inlet, outlet,
and regenerant distributors. The distributors are designed to
direct flows uniformly over the entire bed with a minimum
pressure drop. TBS-Series distributors are constructed of
Sch. 80 PVC.
Media
The cation/anion resin is high capacity resin designed specifically
for demineralization. The cation capacity and attrition loss will
not result in demineralizer capacity loss of more than 3% per
year for three years if operated under the design conditions
specified. The anion capacity and attrition loss will not result in
demineralizer capacity loss of more than 25% within two years
if operated under the TBS-Series design conditions specified.
A bed of quartz protects the bottom distributor. The quartz
media also provides for a means of collecting and distributing
the water for service and backwash, respectively. High quality
quartz is provided, containing low levels of extractable materials
preventing contamination of product water.
Lining
Each tank is lined with 3/16" industrial grade rubber and spark
tested for integrity.
Piping
Standard configuration piping is Schedule 80 PVC with socket
welded fittings except where the attachment of threaded valves,
rotometers and other devices is needed.
Valves
Diaphragm valves are provided for 2" piping and smaller; butterfly
valves are provided for 3" piping and larger. Backwash
and rinse outlet valves are equipped with travel stops to regulate
flow rates during backwash and rinse cycles. An air pressure
filter/regulator is provided. Clean air at a minimum pressure of
80 psig is required for valve actuation. All tubing is polypro.
Individual manual rate set valves are provided on acid and
caustic draw lines. Manual vent valves are provided for each
vessel. Sample valves for service inlet, service outlet, and dilute
chemical sample are provided on each vessel.
Controls
A PLC controller will be provided, fully wired and programmed.
All regeneration times have been programmed into the unit. All
automatic valves are solenoid operated, and include manual
overrides.
Regenerant
The unit is designed to draw concentrated chemicals directly
from client supplied shipping container (carboy, or drum). The
concentrated chemical lines are provided with a PVC wand
attached to a flexible hose. Regenerant acid and caustic are
introduced to each vessel at the proper flow and concentration
by an eductor constructed of non-corrodible material. The flow
of concentrated chemicals are regulated by means of a manually
adjustable valve on each concentrated chemical line.
