In order to re-use greywater indoors for toilet flushing and clothes washing you will need to firstly: Separate greywater and blackwater waste streams. Install a greywater treatment and disinfection system that is approved in your State, so it provides a suitable level of treatment and meets local regulations.
By a systematic review of a company's processes and operations designed to identify and provide information about opportunities to reduce waste, reduce pollution and improve operational efficiency.
Recycled water, is former wastewater that is treated to remove
solids and certain impurities, and used in sustainable landscaping
irrigation or to recharge groundwater aquifers.
Recycled water can be use for agricultural and landscape
irrigation, industrial processes, toilet flushing, and to recharge
ground water basins.
USE OF RECYCLED WATER
Golf course irrigation
Cooling water for power plants and oil refineries
Processing water for mills, plants
Water reuse describes the process whereby wastewater treated to
an appropriate standard, is reused for a variety of beneficial
purposes. The treated water ready to be reused is termed recycled
or reclaimed water.
TYPE OF WASTEWATER FOR REUSE
laundry, kitchen waste
suitable only for outdoor use i.e.
groundwater recharge, fountains
The treatment may be biological, chemical or mechanical.
The qualities of treated water they produce can vary
considerably, as well as their energy consumption and initial
Disinfection is required for indoor re-use of greywater, which
requires regular maintenance.
Chlorine is most commonly used for disinfection. However, it has
adverse environmental impacts.
Alternatives disinfectant can be ultraviolet (UV) or ozone.

REDUCTION OF WASTEWATER IN INDUSTRIES
Key steps of Wastewater Management
Step 1: Analyze manufacturing processes; gain an understanding
of how wastewater is produced.
Step 2: Develop a pollution prevention program based on the
gained knowledge from analyzing the manufacturing process.
Step 3: Choice of candidate treatment technology for proper
process control and waste minimization.
