Advanced Laundry Wastewater Treatment by Varuna: Sustainable, Compliant & Future-Ready Solutions

Introduction: The Laundry Wastewater Crisis

Every wash cycle in a commercial laundry facility discharges more than just dirty water. Detergents, oils, greases, dyes, suspended solids, and volatile organic compounds (VOCs) combine to form a highly polluted wastewater stream that cannot be released untreated into municipal sewer networks.

In centralized settings like laundromats, hotels, hospitals, or industrial facilities, the wastewater volume and pollutant concentration far exceed regulatory limits. Without on-site treatment, this poses significant risks to both public infrastructure and environmental health.

At Varuna, we address this challenge with high-performance Laundry Effluent Treatment Plants (ETPs) designed for maximum purification, reuse, and environmental responsibility.

Why Treat Laundry Wastewater?

Whether it's a commercial laundromat or an in-house hotel laundry, the generated wastewater is:

• Chemically Complex: Contains surfactants, solvents, bleach, softeners, and alkalis

• Solid-Loaded: Lint, fabric fibers, dirt, and undissolved residues

• Biologically Active: High Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD)

Dumping this wastewater untreated not only harms aquatic life but also leads to pipe corrosion, sludge build-up, and potential legal penalties.

Varuna advanced ETP solutions prevent this by filtering, neutralizing, and purifying the wastewater, making it suitable for reuse in non-potable applications like flushing, HVAC, and irrigation.

Grey Water vs. Black Water: Why Greywater Treatment Matters

Greywater, from sources like laundry machines, showers, and washbasins, constitutes a large portion of domestic wastewater. Unlike "black water" (from toilets), it doesn't contain fecal matter but still harbors:

• Detergents

• Body fluids

• Bacteria

• Oils & Grease

Greywater is reusable, but only after proper biological and chemical treatment.

At Varuna, our greywater treatment systems for laundries reclaim 60-80% of used water, turning a waste stream into a sustainable resource.

Varuna's Multi-Stage Laundry ETP Process

Our laundry wastewater treatment plants are engineered using a step-by-step purification sequence to ensure regulatory compliance and high recovery:

1. Pre-Treatment

• Bar screening to remove lint and large particles

• Oil and grease traps

• Grit chamber for settling heavy solids

2. Primary Treatment

• Coagulation and flocculation to remove fine suspended solids

• Sedimentation tanks for sludge separation

3. Tertiary & Advanced Filtration

• Pressure Sand Filter (PSF)

• Activated Carbon Filter (ACF)

• Optional Ultrafiltration (UF) and Reverse Osmosis (RO) for ultra-pure water
