How does ETP plant work?

An ETP is therefore designed to remove the physical, chemical and biological materials present in the effluent. Depending on the level of treatment the wastewater requires, an ETP is divided into four different levels each designed to remove a certain type of material in the effluent.

How do you make an ETP plant?

Design of Effluent treatment Plant

  1. Characteristic of Site in ETP Design. Characteristic of site like soils, topology, geology, hydrology, climate and land use are taken into consideration while designing ETP.
  2. Characteristic of Wastewater in ETP Design.
  3. Questionnaire for ETP Plant Design.

What is the process of water treatment plant?

The 5 major unit processes include chemical coagulation, flocculation, sedimentation, filtration, and disinfection (described below). There are chemicals added to the water as it enters the various treatment processes.

How many levels of treatment are there in ETP?

There are three main stages of the wastewater treatment process, aptly known as primary, secondary and tertiary water treatment. In some applications, more advanced treatment is required, known as quaternary water treatment.

Which chemical is used in ETP plant?

CaO (calcium oxide or lime), MgO (magnesium oxide), Ca (OH) (calcium hydroxide, a hydrated form of lime) or Mg (OH) (magnesium hydroxide) are the most commonly used chemicals because of availability, low cost, and high capacity.

How many types of ETP plants are there?

Some of the major important types of wastewater treatment process are as follows: 1. Effluent Treatment Plants (ETP) 2. Sewage Treatment Plants (STP) 3. Common and Combined Effluent Treatment Plants (CETP).

What is pH control in ETP?

pH control is the process of adding an alkaline or acidic substance to a liquid in order to bring the measured pH within a desired range. For example, most water authority regulators have specifications for the pH range of waste water that is discharged from commercial or industrial sites.
