Household Water Treatment

In terms of water treatment and wastewater or sewage treatment, we generally think of large scale municipal or regional plants with huge equipment, tanks, pools, lagoons etc. But in recent years, following the overall “green” agenda that’s being raised to “center stage”, household water treatment systems are also something that needs attention to and it’s a subject that is developing fast – Both in terms of installed solutions globally and in terms of technological advancements.

Further more regarding household water treatment – Some governments are already applying legislation and regulation to encourage the use of household water recycling systems. This field is widely known as greywater or wastewater recycling or reuse.

Of course household water treatment is not all about recycling wastewater, it is also about improving the fresh water supply that is used domestically and privately for drinking or any other overall use. This common area exists due to health and quality concerns of water supplied by government or private water companies; it involves household water filtration systems, water purifiers, countertop water “mini-bars” and other, more “exotic” methods to treat water.

So in general, household water treatment can refer to what we do with the water after we first use it – recycle and reuse it – or it can refer to the treatment the water goes through before we use it fro the main supply.

Household wastewater treatment

Treating domestic wastewater is normally done using the regular sewage system in the area that delivers the wastewater to the relevant treatment plant. But it can also be done within the household – on site treatment. This practically means that some of the wastewater created by the household is treated and recycled in favor of various uses by a designated domestic system. This can be done to a single private home or apartment or to a complete building.

The relevant wastewater created by a household is called greywater – as opposed to black water from the toilets. Greywater that can undergo household water treatment is the water that comes from dishwashing, bathing and laundry – basically any domestic water that doesn’t involve human waste such as in toilets or very toxic chemicals.

Household water treatment of greywater needs a different plumbing system than the normal pipes leading strait to the sewage, the process is done in a special water recycling system that is normally installed in the yard or garden. A wastewater treatment system can work according to a few methods; it can be quite small and also very large and complex. The principals of this type of household water treatment are that all the solids need to be screened or removed from the water and then the water needs to be purified to a level where it can be used for garden irrigation, toilet flushing etc.

The process of household water treatment and recycling can involve different types of filters, sedimentation tanks, biological water purification processes using technological systems or a wetland basin to eliminate pathogens and contaminants. The treated greywater can be used with a pump, undergo another household water treatment process with carbon filters and similar equipment. Overall this is an economic, sustainable, water saving solution for household water treatment.
