Quick Answer: What Are The Types Of STP?

What is STP and its types?

STP—Defined in IEEE 802.1D, this is the original standard that provided a loop-free topology in a network with redundant links.

Rapid Per-VLAN Spanning Tree (Rapid PVST+)—Rapid PVST+ is a Cisco enhancement of RSTP that uses PVST+ and provides a separate instance of 802.1w for each VLAN..

What are the 3 types of sewage treatment?

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.

What is WTP and STP?

Environmental Solutions, Sewage Treatment Plants (STP), Efflaent Treatment Plant(ETP) & Water Treatment Plant(WTP) | NT AGNI.

What is STP used for?

Spanning Tree Protocol (STP) is a Layer 2 protocol that runs on bridges and switches. The specification for STP is IEEE 802.1D. The main purpose of STP is to ensure that you do not create loops when you have redundant paths in your network. Loops are deadly to a network.

What is difference between STP and RSTP?

The main difference between Rapid Spanning Tree Protocol (RSTP IEEE 802.1W) and Spanning Tree Protocol (STP IEEE 802.1D) is that Rapid Spanning Tree Protocol (RSTP IEEE 802.1W) assumes the three Spanning Tree Protocol (STP) ports states Listening, Blocking, and Disabled are same (these states do not forward Ethernet …

What is the first step of sewage treatment?

Primary treatment in sewage treatment involves physical removal of particles (large and small) from the sewage through filtration and sedimentation. Initially floating debris is removed by sequential filtration. Then the grit (soil and small pebbles) are removed by sedimentation.

What is STP and how it works?

Spanning Tree Protocol (STP) Operations The Spanning Tree Protocol (STP) is responsible for identifying links in the network and shutting down the redundant ones, preventing possible network loops. In order to do so, all switches in the network exchange BPDU messages between them to agree upon the root bridge.

What is STP value?

STP values are most often cited for gases because their characteristics change dramatically with temperature and pressure. One common definition of STP is a temperature of 273 K (0° Celsius or 32° Fahrenheit) and the standard pressure of 1 atm. Under these conditions, one mole of a gas occupies 22.4 L.

Is STP better than UTP?

UTP cables contain no shields and they are thinner than STP cables, which is easier for cable installation and maintenance, particularly in limited space. While the shields of STP cables are quite fragile and rigid. If the shield suffered damage, cabling systems are likely to be affected by interference.

What are the chemicals used in STP plant?

How many types of STP plants are there?

There are four ways in which a water treatment plant can operate: Effluent Treatment, Sewage Treatment, Common and Combined Effluent Treatments, and Activated Sludge Treatment.

What is ETP & STP?

Effluent Treatment Plants (ETP) 2. Sewage Treatment Plants (STP) 3. … Wastewater treatment is a process, wherein the contaminants are removed from wastewater as well as household sewage, to produce waste stream or solid waste suitable for discharge or reuse.

What is STP in society?

Sewage treatment plant (STP) plays a vital role in the process of removing the contaminants from sewage to produce liquid and solid (sludge) suitable for discharge to the environment or for reuse. … Waste water is produced from toilets, baths, showers, kitchens, sinks, and so forth that are disposed off via sewers.

How do I set up STP?

What is STP connection?

The Spanning Tree Protocol (STP) is a network protocol that builds a loop-free logical topology for Ethernet networks. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them. … RSTP was designed to be backwards-compatible with standard STP.

What is full form STP?

STP stands for Sewage Treatment Plant. It is a facility that receives the waste from domestic, commercial and industrial sources and filters it to remove the harmful substances that deteriorate water quality and affect public health and safety when discharged into rivers, canals, and other water bodies.

What is STP state?

When the Spanning Tree Protocol (STP) is enabled, every switch in the network starts in the blocking state and later changes to the listening and learning states.

What is KLD STP?

KLD (Kilo Liters per day)

What is STP capacity?

SEWAGE TREATMENT PLANT TREATMENT SCHEME It is proposed to install STP of capacity 1,15,000 litres/day, Following is the scheme for treating 1,15,000Liters/day capacity sewage. The treated water can be utilized for Toilet Flushing & gardening.

What are the methods of sewage treatment?

Four common ways to treat wastewater include physical water treatment, biological water treatment, chemical treatment, and sludge treatment. Let us learn about these processes in detail. In this stage, physical methods are used for cleaning the wastewater.

What are the 5 stages of water treatment?

These include: (1) Collection ; (2) Screening and Straining ; (3) Chemical Addition ; (4) Coagulation and Flocculation ; (5) Sedimentation and Clarification ; (6) Filtration ; (7) Disinfection ; (8) Storage ; (9) and finally Distribution.
