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.
Correspondingly, How many types of sewage treatment plants are there? 4 Types of Sewage Treatment Plants.
What is STP plant? Sewage is the waste generated from residential, institutional, commercial and industrial establishments. STP plant treats the sewage to make it fit for safe disposal, agricultural use or domestic use in toilets etc.

What is the ETP?
Key Takeaways. Exchange-traded products (ETP) are types of securities that track underlying security, index, or financial instrument. ETPs trade on exchanges similar to stocks. The price of ETPs fluctuates from day-to-day and intraday. The share price of ETPs come from the underlying investments that they track.
What is MBR STP? Membrane Bioreactor or MBR Sewage Treatment Plant is an innovative wastewater treatment method. As the name suggests, it combines two technologies, membrane filtration and the biological treatment.
What are the types of STP? Following are few STP process & System commonly used in India.
- Activated Sludge Process.
- Moving Bio Bed Reactor (MBBR)
- Membrane Bio Reactor (MBR)
- Electro Coagulation System.
- Sequential Bio Reactor (SBR)
- Rotating Bio Reactor (RBC)
What are the two types of sewage treatment plant? What are the different types of sewage treatment plants available and the benefits of each system
- Activate Sludge Process (ASP) …
- Fixed bed reactor. …
- Non-electric filter. …
- Rotating Disc System / Rotating Biological Contractor (RBC) …
- Sequence Batch Reactor (SBR) …
- Submerged Aerated Filter.
What is ETP and STP?
Difference between Effluent treatment plant (ETP) and Sewage treatment plant (STP) 1- ETP may be a system that removes toxic and non-toxic material from water and making it usable for various purposes. STP unit removes contaminants from municipal wastewater or household sewage.
What is STP capacity? Sewage Treatment Plant (STP), Capacity: 5 KLD to 50 MLD, Waste Water Treatment Plant.
Which bacteria is used in aeration tank?
With a normal influent load of pollutants, the dissolved oxygen content in the aerated section of most plants should be kept between 3 and 5 MG/L. Anaerobic bacteria are normally used in an anaerobic digester to reduce the volume of sludge to be disposed of and to produce methane gas.
Why is ETP important? Effluent treatment plant cleans industrial effluents, contaminated water from outlet pipes, reservoir, rivers, lakes etc and reclaim the water resource for using in different purposes. ETP are mostly installed in industries like textile industry, Medicine manufacturing, leather industry, and chemicals industry.
What are the 5 stages of water treatment?
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.
What is ETF and ETP?
Don’t confuse Exchange-Traded Products with Exchange Traded Funds. Over 97% of the $5 trillion global ETP market consists of exchange traded funds (ETFs), which are plain vanilla, traditional, liquid funds. ETP’s are financially engineered investments that bet on against the very indexes that they track.
What chemicals do ETP plants use? ETP Plant Chemicals
- Poly Aluminium Chloride Liquid. Rs 15/ kg.
- Cationic Polyelectrolyte Powder. Rs 330/ Kg.
- Poly Aluminium Chloride Powder. Rs 45/ per kg.
- Caustic Soda Lye. Rs 45/ Kg.
- Caustic Soda Flakes. Rs 48/ Kilogram.
- Anionic Polyelectrolyte. Rs 245/ Kilogram.
- Ferric Chloride Liquid. Rs 55/ per kg.
What is difference between SBR and MBR? The main difference between MBR and SBR water treatment plant is MBR uses the membrane technology and SBR uses the phase separation with the gravity setting method. Membrane the physical barrier for separation gives more importance to treat sewage water than other methods.
What is MLSS in wastewater treatment?
MLSS are the concentration of suspended solids in mixed liquor, usually expressed in grams per litre (Wateronline, 2011). Mixed liquor is a mixture of raw or settled wastewater and activated sludge contained in an aeration basin in the activated sludge process.
What is difference between MBBR and MBR? MBR can effectively improve sludge load, while MBBR belongs to biofilm process, both of which have good effect on organic pollutant treatment, including COD, BOD and ammonia nitrogen. MBR has obvious effects in treating SS, but it is a problem that it is easy to block the membrane.
What is ASP in wastewater treatment?
The activated sludge process is a type of wastewater treatment process for treating sewage or industrial wastewaters using aeration and a biological floc composed of bacteria and protozoa.
What is STP plant process? Sewage treatment is the process of removing contaminants from wastewater, primarily from household sewage. It includes physical, chemical, and biological processes to remove these contaminants and produce environmentally safe treated wastewater (or treated effluent).
