Gray water treatment plant

Components of a gray water treatment plant

The gray water treatment plant is of great importance in water recycling, which has a positive role in rationalizing water consumption and preserving the environment. We provide Carewater with all water solutions in a manner commensurate with global developments and the volume of consumption in our beloved Kingdom.

What is gray water

Gray water is the water that comes out of sinks, bathtubs, washing machines, and floor basins.

Gray water takes its name from the gray color it turns after domestic or industrial use in laundry.

How do we benefit from gray water?

Gray water is characterized by its ease of refining, cleaning, and reuse compared to black water. Purification and recycling devices can now be installed at home for this purpose, unlike black water which requires large and complex treatment plants.
There are many modern technologies and innovations that have been recorded in the world, which enable gray water to be purified and reused in several fields, perhaps the most prominent of which is its use in the irrigation of gardens and crops, and its return again for use in centrifuges (siphon water). In fact, modern technologies enable gray water to be restored to its former state, pure and drinkable as well.

Characteristics of gray water treatment plants

Gray water does not contain organic matter.

Gray water treatment plants are plants designed to recycle and reuse water in the same or other places such as irrigation, agriculture, and bathrooms.

Advantages of gray water treatment plants provided by Water Care

  • Medium size and suitable for all places
  • Value price
  • Low maintenance and operating costs

Where is gray water used?

  • Car wash stations
  • Domestic gray water treatment for showers and tubs
  • Industrial gray water for washing water recycling

Types of gray water

Wastewater treatment plants are divided into three sections and greywater treatment methods:

  1. Domestic gray water.
  2. Gray industrial water.
  3. Natural gray water.

Each of these types has a treatment method and has customized specifications that are manufactured according to the specifications or analysis of the water to be treated.

Components of a gray water treatment plant

Components included in a gray water treatment plant:

  • Raw water feed pumps
  • Polyelectrolyte injection unit
  • Unit for removing impurities (sand filter)
  • Activated carbon unit
  • Deodorant injection unit
  • Micron filter unit
  • Chlorination unit
  • Electrical control panel
  • Piping, connections, and electrical panel

Site preparations prior to installing the gray water treatment plant

Some equipment must be available in place in the establishment to treat gray water, of course, it varies according to the size of the station to be implemented:

  • Separation of gray water drainage from black water and kitchen water because it contains oils (oils need separate and tiring treatment, but in car washes, an oil separator must be installed).
  • Collecting gray water in a main tank (by making another branch of drainage on the wastewater used for emergencies) so that the location of the tank is close to the treatment unit room at a distance of no more than 4 meters.
  • Establishing a strainer on the collection tank to collect solid and large materials, so that the inter-network distances do not exceed 25 mm.
  • The capacity of the collection tank depends on the ability of the required treatment unit.
  • Provide a tank for the produced water, the capacity of which is suitable for the ability of the required treatment unit.
  • Provide a source of electric current inside the treatment room.
  • Preparing a room for the treatment unit, the area of which depends on the capacity of the station.
  • Create a network to reuse the produced water, whether to siphons or to agricultural areas.
