Understanding Water Evaporation

Evaporation is a natural process that converts liquid water molecules into a gaseous state. This process is accelerated by:

  • Surface Area - Larger water surfaces lose more water
  • Temperature - Higher temperatures increase evaporation rates
  • Wind Velocity - Air movement carries away water vapor faster
  • Aridity - Dry air absorbs more moisture from water surfaces

In tropical and surrounding regions (up to 4,000+ km from the equator), water bodies can lose 1 to 3.5 meters of water depth every year to evaporation alone. This includes 50 plus countries, situated in Asia, Europe, Africa, Australia, North and South America Continents.

Ultra-Thin Film Technology

Evaloc continuously forms an invisible, mono-molecular film over the water surface that significantly reduces evaporation with the help of following:

Evaloc SRP (Sustained Release Pack)

A specialized, non-toxic, organic compound that spreads gradually across water surfaces to form a protective molecular film. Bio-degradable and safe for all aquatic life.

SFMDA (Stationary Floating Marked Dispensing Apparatus)

Specially designed floating anchored bags that release Evaloc material consistently across the water surface. Self-regulating deployment system.

MPDT (Multi Point Dispensing Technique)

The patented application method ensuring optimal coverage and sustained protection. Includes site assessment, material calculation, and deployment protocols.

The Evaloc Process

1

Site Assessment

Our team conducts a comprehensive site study to calculate current evaporation loss, assess environmental factors, and determine the optimal deployment strategy.

  • Water body surface area measurement
  • Evaporation rate calculation
  • Environmental factor analysis
  • Cost-benefit assessment
2

Material Deployment

Evaloc material is placed in floating anchored bags at strategic positions across the water body. The dosage is precisely calculated: 1 gram per square meter per 10 days.

  • Strategic placement of SFMDA bags
  • Anchoring to prevent drift
  • Dosage calculation per surface area
  • Coverage verification
3

Film Formation

Evaloc continuously releases from the floating bags, spreading across the water surface to form an ultra-thin molecular film that blocks evaporation.

  • Continuous material release
  • Self-spreading film technology
  • Automatic re-formation after disturbance
  • Consistent coverage maintained

Performance Monitoring

Results are measured using Class A evaporation pans - one with Evaloc and one without. The difference indicates water savings, typically achieving 30% ± 20% reduction.

  • Dual pan measurement system
  • Regular reading intervals (10 days)
  • Documented water savings
  • Performance optimization

Measuring Results

Evaloc effectiveness is verified using the internationally recognized Class A evaporation pan method. Two identical pans are installed at the site:

Pan with Evaloc

Protected by molecular film, shows reduced water loss

vs

Control Pan

No treatment, shows normal evaporation rate

Water Saved = (Control Pan Loss - Evaloc Pan Loss) × Water Body Surface Area
