Typically, effluent is conveyed by drains to sewers, and from sewers to a suitable outfall or treatment plant.
How do wick drains work?
Wick drains, also known as Prefabricated Vertical Drains (PVD) are prefabricated geotextile filter-wrapped plastic strips with molded channels. These act as drainage paths to take pore water out of soft compressible soil so it consolidates faster, often from decades to months.

What is an open drain pin?
An open-drain or open-collector output pin is simply a transistor that is connected to the ground. Whenever we apply high input at the gate, drain, and source are shorted. Whenever we apply low input at the gate, drain, and source are disconnected. To make it simple, open-drain is like a switch that will get connected or disconnected basing on ...
How to drive LEDs?
How to Drive LED. In order to drive LED first, activate the internal pull-up resistor after connecting the LED to the pin. For turning on the LED just give 1 as input so that it is inverted as 0 and the transistor will get turned off. When it gets turned off, a pull-up resistor will help LED will be driven to Vcc.
What is the function of a transistor?
Transistor takes control of the flow of current and voltage potentials through circuits made with billions of transistors, basing on IC. When the NPN transistor is open but connected to an external pin then it is an open collector this will make the transistor switch to ground when it’s active.
What is an open drain vs open collector?
In an Open Drain vs Open Collector, An open-drain is CMOS and an open collector is BJT. When currents are low BJTs saturation voltage is a bit higher than the voltage drop due to RDS for FET.
How many switches are in a push pull switch?
Switches. It consists of only one switch which is connected to the ground. Push-pull will contain two switches. One switch is connected to the ground and another switch is connected to Vcc.
Can a GPIO pull up a pin?
Open-drain output configuration can’t pull up the pin it can only pull down the pin. The open-drain output configuration of GPIO is useless until and unless it is provided with pull up capability. Open Drain GPIO. To make use of this in real-world applications, it has to be used with an external pull up resistor or internal pull-up resistor.
Does push pull drive external loads?
Loads. Push-pull will not drive external loads. An open-drain will drive external loads less than or equal to 10ma directly.
What is an Open Drain?
It is also called Open Collector which is a transistor having a connection with the ground pin. In a simple way, it behaves like a switch that gets connected or disconnected depending on the input signal. This open-drain configuration permits different devices to establish communication bi-directionally on one wire.
Circuit and Working
In most of the integrated circuits, the observed output configuration type is open-drain. As a replacement for outputting a signal with a corresponding current or voltage, the output is fed to the base terminal of the NPN transistor, and the collector terminal is externally connected to the integrated circuit pin.
Open Drain Configuration
The open-drain configuration is employed at the controller’s output port in order to lessen the output circuitry. When the output port is fixed at open-collector/drain state, then there is no additional equipment necessary for pulling down the pin’s output value.
What does "open drain" mean?
The term “open drain” means there’s a current sink, but on a FET device, for example, a MOSFET.
What happens when an open drain device is set to sink current?
Thus, if any one of the open-drain (open-collector) devices is set to sink current, current flow for all of the devices gets sunk to the ground, since they are all connected at the same point. that holds the signal line high until a device on the wire sinks enough current to pull the line low. Many devices can be attached to the signal wire.
What is the opposite of a current sink?
The opposite of a current sink is a “current source, ” which is when the pin is driving an output current and therefore supplying current to whatever is connected to that pin. (Continuing the kitchen analogy, the current source would be the water spigot.)
What happens when a device is attached to a signal wire?
Many devices can be attached to the signal wire. If all devices attached to the wire are in their non-active state, the pull-up will hold the wire at a high voltage. If one or more devices are in the active state, the signal wire voltage will be low.
Is an NPN transistor an open collector?
If an NPN transistor is left unconnected, or open but connected to an external pin, it’s an open collector. The transistor will switch to ground when it’s active, thus “sinking” current (i.e., connecting to ground and thus current is shunted to ground for “recycling” in the ground plane). Both a current source and a current sink have current ...
Can you use an open drain resistor with a pull up resistor?
It is fairly common to use open-drains (open-collectors) together with a pull-up resistor. The pull-up resistor is connected to high (supply voltage) at one end and connected to one or more external pins of the open-drain/-collector devices all connected together.
What are the uses of drainage systems?
There are two uses for a drainage system as part of existing and developing urban systems or cities. Drainage systems are in place to remove the excess water in development. This could be floodwater, rainwater, and different kinds of run off.
What happens if you don't have a drainage system?
Not having a proper drainage system in place will result in flooding of low-lying areas, thereby causing property damage and health risks. An effective drainage system is the one that removes all excess water without causing inconveniences in terms of design.
What is closed drain?
Closed drain forms a complex network underground. The primary refuse from individual areas is collected and transported to the main network which finally goes to a treatment plant. An open-drain is mostly used to collect wastewater that is not sewage.
Can stormwater and sewer be separated?
Drainage systems can be separate for stormwater and sewers but sometimes both these inputs drain into the same underground drainage system. The advantage of having separate drainage systems is that stormwater run off is not so dangerous that it has to be treated. This can be drained directly into water bodies.
Is it safe to use an open drain?
Use of open drains to dispose of sanitary waste is extremely unhygienic and unsafe. Use of open drains to a certain degree can be acceptable. However, any place with a collection of water breeds various disease-carrying pathogens.

What is the pleural cavity?
The pleural cavity is the space lying between the pleura (two thin layers that surround the lungs). This space contains a small amount of liquid known as the pleural fluid, which acts as a lubricant for the expansion and contraction of the lungs during respiration. When there is an excessive collection of the pleural fluid or build-up of air, ...
What is the difference between hemothorax and empyema?
Hemothorax: It is a collection of blood in the pleural cavity. Empyema: It is a collection of pus in the pleural cavity. You will need open pleural drainage when you are so debilitated that you cannot undergo an extensive surgical procedure for draining your pleural fluid. Your doctor will prefer open pleural drainage over other techniques if.
Why is pleural drainage less commonly used?
Although open pleural drainage is less commonly used nowadays because of appropriate antibiotic usage and use of alternative techniques (thoracostomy and thoracotomy), it is still reserved for very ill patients who cannot undergo any other procedure to drain their pleural cavity.
How big is an Eloesser flap?
Your doctor may also give you painkillers and sedatives. The doctor will make a large U-shaped incision (5 cm wide and 6-7 cm long) known as an Eloesser flap. Optionally, doctors can make an H-shaped or inverted U-shaped incision.
