Zero Blowdown Technology
Eliminate Chemicals and Save Water
with WCTI's
Patented Technology
for Cooling Towers |
|
- Mitigates scale, corrosion and
bio-fouling without blowdown or chemicals.
- “New Dimension” cooling technology
permits operation at high TDS / Zero Liquid Discharge
- “State of Art” Corrosion & Scale
Inhibition at 10-100,000 TDS tower water
- Water use reduction and cost savings
without acid, scale or corrosion risks
- Six corrosion and scale inhibition
patents (Patents US6929749; US6949193; US6998092;
US7122148; US7517493; EP1704123)
- It doesn't get any greener,
this technology uses natural chemistry in the source
water

| How Zero
Blowdown Technology Works
|
- Proprietary pre-conditioning
system removes scale forming ions from tower make-up
- Permits unlimited makeup water
concentrations (10-500 COC)
- Silica concentrates without
deposition (200 - 800 Mg/L soluble silica)
- Silica chemistry protects metals
from high TDS corrosion
- High TDS and pH prohibits bio &
pathogen growth
|
|
|
ZBT Benefits
|
- Typically reduces total
treatment cost by 50% or greater
- Ideal corrosion protection (<0.2
MPY for steel, copper, galvanized steel, aluminum)
- Non-toxic chemistry and / or
eliminate discharge
- No chemical handling & storage
- Reduced testing and operator
time
- Ideal for high silica or reuse
(wastewater) makeup waters
- Eliminates “bleed & feed” water
wastage and chemical costs
|

|
Application Experience
|
- Six years of potable water
application and evaluation
- Three years using recycled water
application
- Customers include Industrial,
Food, and Commercial/Institutional systems.
- System metals tested include
mild steel, copper, galvanized steel, aluminum,
stainless.
- Cooling towers include Marley,
BAC, Evapco, Delta, others.

Program Implementation
|
- Survey design capacity, load,
water quality
- Proposal / water savings
comparison
- Purchase & install pre-treat
system
- Monthly flat fee for method use
and service
- Pre-treat start-up and program
transition
- Performance monitoring &
reporting
|
| |
| Pre-conditioning Systems
|
- Proprietary design; salt use
4 lbs/ft3 resin
- 30-50% lower salt use, 75% lower
regeneration waste water
- Polished quality with minimum
hardness ion leakage
- Dual units for continuous
treated supply
- Preventative maintenance program
- Economical design & simple
operation
