Cleaning a water tank is not just about draining the water and sweeping the floor. To ensure the water you use for brushing, cooking, and bathing is 100% hygienic, we employ a scientific 6-stage sanitization process that eliminates chemical residues, sludge, and microscopic bacteria.
Stage 1: De-watering. We use high-capacity submersible sludge pumps to drain out the dirty water and loose sediments. Stage 2: Sludge Removal. Technicians manually extract the thick mud and debris settled at the bottom of the tank. Stage 3: High-Pressure Washing. We wash walls, ceilings, and corners using industrial jet pressure washers to strip away algae, calcification, and stains without damaging the tank's surface.
Stage 4: Vacuuming. A specialized wet vacuum pump sucks out all the dirty slurry and water droplets, leaving the tank dry. Stage 5: Non-Toxic Spray Disinfection. We spray a WHO-compliant, food-grade sanitizing solution on all internal walls. Stage 6: UV Sterilization. We use germicidal ultraviolet tubes to neutralize any remaining invisible pathogens, leaving your tank sterile and ready to supply clean water.
Frequently Asked Questions About This Topic
What are the key steps in a 6-stage water tank cleaning process?
The 6 stages include: 1. De-watering 2. Sludge Removal 3. High-Pressure Jet Washing 4. Slurry Vacuuming 5. WHO-compliant Sanitization Spray 6. UV Germicidal Irradiation.
How long does the 6-stage sanitization process take?
For standard overhead plastic tanks (500L - 2000L), the entire 6-stage process takes 45 to 60 minutes. Underground sumps usually require 1.5 to 2 hours.
Is the 6-stage sanitization spray safe for drinking water?
Yes, we strictly use WHO-compliant, food-grade, chlorine-free disinfectants that decompose safely into water and oxygen without chemical residue.
What is the role of UV germicidal irradiation in tank sanitization?
High-intensity UV-C light targets dry tank surfaces to destroy microscopic virus and bacterial DNA that manual scrubbing alone cannot remove.
Does high-pressure jet washing scratch plastic Sintex tanks?
No. Pressure washers are calibrated to optimal PSI settings that effectively strip algae and dirt without abrading or damaging plastic surfaces.
Why is wet vacuum extraction better than manual wiping?
Wet vacuuming sucks out fine suspended sand particles and dirty water droplets from corners, leaving the tank floor 100% dry and sediment-free.
