EFLO Grey - High Rate Biological Water Treatment
From Wastewater Treatment
Domestic water usage continues to put higher demands on municipal supplies and bigger costs on consumers. Grey water recycling is used for toilet flushing, irrigation.

Grey water is usually considered to be all the waste water from a residence but excluding the black water. Black water is from the toilet and kitchen sink.

Ideally suited to new build developments where dual drainage can be designed in at an early stage. The grey water is collected and treated separately from the black water. The use of treated and recycled grey water within a development will require a separate pressure supply from the potable water supply. This is already commonly used in some Far East nations.

EFLOGrey Treatment Process
Previously, Grey Water just excluded toilet water - the Black Water. Hence Grey & Black Water. The EfloGREY process also excludes kitchen & dishwasher water since this is very high in BOD and fats oils & greases. The result is Light Grey Water.
Treatment of Grey Water must address all of the contaminants and it must be treated to a quality whereby it is of use in daily life.
The reality is that Grey Water contains solids, hairs, organic contaminants, oils, bacteria/E-Coli and measurable levels of BOD.
The EfloGREY process includes: Pre-disinfection with chlorination and ozone, self cleaning pre membrane filter, Ultra Filtration membranes, auto membrane cleaning system, stored filtrate disinfection with chlorine.
