Zero Blowdown Tower Treatment Overview
Zero Blowdown – Zero Liquid Discharge Technology is a Non-Chemical – Chemical-Free Water Treatment System Creating WCTI Conditions for all Cooling Tower Needs
American Made and Patented Technology for Cooling Towers and Water Reclamation
Overview
- Controls scale, corrosion and bio-fouling without bleed or chemicals.
- Allows tower operation at elevated TDS levels (up to 200 cycles of concentration without the need for blowdown.
- Advanced corrosion & scale inhibition at 10-100,000 TDS tower water.
- Reduced water consumption and cost savings without acid, scale or corrosion risks
- Proprietary corrosion and scale inhibition patents (US Patents #6,929,749; #6,949,193; #6,998,092; #7,122,148)
- True green technology utilizing natural chemistry in the source water
How the Technology Works
- Technology specific, pre-conditioning system removes scale forming ions from tower make-up
- Allows tower to cycle up to unlimited makeup water concentrations (10-100+ COC)
- Permits silica concentrates without deposition up to 200 – 800 Mg/L of soluble silica.
- Silica based chemistry protects tower, chiller and piping metals (steel, copper, galvanized steel, aluminum) from high TDS corrosion
- Develops high TDS levels prohibiting biological & pathogen growth
- Develops and maintains WTCI conditions
Provided Benefits
- Reduces on average total treatment cost by 50%
- Exceptional corrosion protection (<0.2 MPY for steel, copper, galvanized steel, aluminum)
- Non-toxic chemistry
- Eliminates discharge (blowdown / bleed)
- No chemical handling & storage
- Reduced testing and operator time
- Ideal for high silica environments
- Allows reuse of wastewater/grey water) for makeup
- Eliminates “bleed & feed” water wastage from chemical programs
Field Experience and Application
- Over five years of application and evaluation
- Clients include Industrial, Food, Manufacturing facilities, universities and hospitals, etc.
- Tower and piping metals tested include mild steel, copper, galvanized steel, aluminum and stainless steel
- Appropriate for all tower manufacturers and scalable to any tower size
