ZERO LIQUID DISCHARGE COOLING WATER
TREATMENT
We are introducing new patented technology
(developed by WCTI) for Zero Liquid Discharge cooling water treatment. This
technology mitigates scale, corrosion and bio-fouling without blowdown or
chemicals. “New Dimension” cooling technology permits operation at high TDS /
Zero Liquid Discharge and provides “State of Art” Corrosion & Scale Inhibition
at 10-100,000 TDS tower water. Benefits are water use reduction and cost savings
without acid, scale or corrosion risks.
Reuse treated wastewater as cooling tower make-up:
WCTI technology allows us to reuse treated wastewater as cooling water due
to unique operating conditions. High TDS, nutrient content, ammonia or presence
of bio-organisms typically causes problems in reuse of treated wastewater as
cooling tower make-up using conventional chemistry. With WCTI technology, we can
reuse treated wastewater with high TDS, nutrient content, ammonia or presence of
bio-organisms as cooling tower make-up.
How WCTI 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
WCTI Technology 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
- Green Technology
Application Experience:
- Five years of potable water application and evaluation
- Two years using recycled water application
- Customers include Industrial, Food, and Commercial/Institutional systems
- System metals tested include mild steel, copper, galvanized steel, aluminum,
stainless steel.
- Cooling towers include Marley, BAC, Evapco, Delta, others.
