Recycling household grey water

Biomimicry Technologies Private Limited (BTPL) is a company based in New Delhi, India, focused on developing innovative solutions that mimic natural processes. Among its key offerings is the Urban Pure Grey Water Recycling System, designed to recycle household grey water for various applications, contributing to sustainable water management practices.

About the technology

The Urban Pure Grey Water Recycling System employs advanced membrane-based technology to treat grey water sourced from sinks, basins, showers, baths, washing machines, and dishwashers. The system utilizes a multi-stage process that includes the following key steps:

Collection and Pre-Treatment: Grey water is collected in a 3000L underground well with an overflow to the sewer or treatment system during peak flows.
Aeration: The collected grey water is then transferred to the Urban Pure waste treatment unit, where it undergoes constant aeration to break down organic matter.
Membrane Filtration: The aerated water passes through flat sheet membranes with pores smaller than 0.8 microns, effectively filtering out contaminants and allowing only pure water to pass through.
UV Disinfection: The filtered water is subjected to UV treatment, ensuring that the treated water is safe for reuse.
This system is solar-powered and designed for low energy consumption, making it an environmentally friendly solution.

Advantages

The Urban Pure Grey Water Recycling System offers several advantages:
High-Quality Water Production: The system produces treated water that is safe for use in non-potable applications such as toilet flushing, vehicle washing, and irrigation.
Chemical-Free Process: The system operates without the need for chemicals, making it safe and environmentally sustainable.
Odor-Free Operation: The treatment process is designed to eliminate odors, ensuring a pleasant user experience.
Low Maintenance and Cost-Effective: The system is lightweight, easy to install, and economical, with proven reliability and durability.
Energy Efficiency: Powered by solar energy, the system is designed to have low energy consumption, further reducing its environmental impact.

Applications

The Urban Pure Grey Water Recycling System has a wide range of applications across various sectors:

Residential and Societies: The recycled grey water can be used for toilet flushing, washing machines, floor washing, hand wash, horticulture, and gardening.
Municipal Areas: Applications include public utility flushing, floor washing, gardening, and road washing.
Industrial Areas: The treated water can be used for production floor washing, utensil washing, and other industrial processes.
