TLT: Teknologi Pengolahan Limbah Cair 2

Bismillahirrohmanirrohim Assalamualaikum warahmatullahi wabarakatuh Which I am proud of my fellow students I hope all of you are always encouraged by health, safety and success Let's start this meeting with a prayer Prayers are allowed Okay, fellow students that I am proud of On this occasion, we will continue together

discussion on the technology of processing liquid wastewater, yes, in the previous meeting, we had discussed together the big picture, yes, the general picture and the big picture, the big line related to the installation of wastewater treatment in the center, yes,

starting from the service subsystem, the collection subsystem, then the processing subsystem. We will discuss in this meeting about this first stage management. So the first stage management consists of the collection, inlet, then

the net or screen net then the catcher of sand or chamber equalization and first irrigation or primary sedimentation. Well, this inlet collector has various types of collector, so from the

collection will enter the installation of wastewater treatment, enter the collection tank first, so in the collection tank there is a collection tank with a wet pump, the pump will be soaked in the wastewater, so it's wet, wet type, there's actually a dry pump, what's the name of

to flow or pump liquid later to other components, now here, for example, this is a led collector screw with a pump screw, so this is the liquid, the liquid enters here,

This type is like a dry pump but using a screw, so the liquid will enter the screw or the water will enter the holes here, the liquid will enter here

If the weight pump is usually sucked, maybe the air pump is sucked to go up Because sometimes the collector of LEDs is positioned below So sometimes for the next gravitational system to the next processing component, there needs to be a pump So there is a pump to flow it

Usually in this internet collector there are also several components, so the garbage collection can also enter the position of the components here, so there is a pump, the pump component, then the garbage collection, the garbage collection, the position or function

to remove or clean rough materials, so it's more like rough materials, like sometimes there must be plastic in the tap water, then there is what, for example, the less wrapped one that is still there, it turns out to be put into the closet, then into the tap water pipe flow, then it can enter the

to the subsystem of processing, yes, that's why there must be a garbage dump. Well, this garbage dump, if the raw materials are other than that, there may also be stones or bricks later, which will definitely destroy other equipment, then reduce the effectiveness, then the reliability of the work of the next wastewater installation, yes.

then it can also control the channel. There are several types of garbage collection, some of which are still using manual, so later this garbage will be collected on this screen, in the collection here, then cleaned manually, maybe lifted, so it's lifted

There is a lever to lift the garbage. So it's more manual. The mechanical one is more automatic. It still uses automation. It's automatic to set the time and the time limit. Then the garbage is taken here. Actually, there are advantages and disadvantages for this type of manual or mechanical.

For example, this is more of a mechanical type, this is more of a manual type. So after going to the collector, there must be a garbage collection. Garbage collection is of various types of mechanical types. There are various types of garbage collection.

So this is the flow from here, and later the garbage will be transported here Then if this one is lifted up there, if this one is turned here This is the direction of the arrow, yes, there So to lift the garbage Well, there are various types, and this is to consider actually

The control of various types or mechanisms depends on the type Usually done by study first Usually use manual first Then there will be filtered What rough material is filtered there So later after knowing the types and volumes of

from what garbage or rough material that was dumped earlier, then adjusted to which mechanism screening or the right garbage collection usually in the garbage collection there is a water gate, yes, the gate is here, we usually set up to open and close the channel, so there is a way to control or

need to be opened or closed, then the screen itself, the storage itself and also the place to store the garbage. This is the reason, yes, the flow, so here the garbage that was stored was lifted, then put it in here, then enter the storage box. Well, this is also an easy mechanism for automation, yes, it's already using automation if it's like this. Well, next from

garbage dump or garbage dump or the screening earlier entered the sand trap so the sand trap or the chamber Yes, it's almost the same. What's the name of the function that protected the operational of the mechanical equipment, namely

garbage collection is also the same, protecting the equipment, yes, in the garbage collection, one of its functions is to protect the operational equipment of the mechanic, then prevent dams in the pipe, the accumulation of dams in the pipeline, prevent the effect of sedimentation below in the mud gaster and the first dam tank. If later there is sand, then there is mud, then what

there are reactions so that there can be a cooling effect in the tank or in the gaster so that will shorten the age of the air-conditioning installation then reduce the accumulation of these materials in the aeration pond and in the gaster lumpur sand also turns out to be a lot of what can

can interfere with the installation of a floodplain, so it must be removed first from the floodplain, so the sand water component must be removed. There are also several mechanisms for this grid chamber, there is an aerated grid chamber, so the inlet is from here, then there is a spiral flow pattern,

usually this is the sand will fall here because the weight of the type is heavier than the water, the spiral is then here, the water comes out of the pool, the area is the chamber, then there is also the type of protect chamber, so the type of protect is here, the inlet is without what side, yes, if this is without the top,

C inlet, then the outlet is here, so it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this, it looks like this

the composition of the sand, the material of the sand has been reduced, so the water will come out here for the next stage, for the next stage of processing. Well, this is a sand trap, yes, next from the sand trap, from the chamber, it enters the equalization, so the water will enter the equalization. Well, in the equalization,

function is to divide the flow of the water, so to divide it, we know that the flow of the water is sometimes very high, the flow can also be low, it's not necessarily like that, the flow is straight, the flow is medium, it's sometimes unstable, it's not constant, so it varies

the debt can reach the high pass, then the low pass, then there is a need for equalization here, so to divide the debt of the reservoir when it wants to enter the next processing, so after the grid chamber or the catchment of the result, enter the equalization, here it is often

the flow rate of the water flow is variable. After entering here, after leaving the equalization, the flow rate of the flow is relatively constant here. So because it is already set here, there is a control to adjust the flow. So one of the considerations why equalization is needed is

to increase the performance of its biological treatment so later there is biological treatment if there is a shock loading effect, so for example the chest suddenly has high debits, the chest suddenly has high debits, then the volume is high, the chest can interfere with the performance of biological treatment

detention time or the time left in the equalization is usually a maximum of 30 minutes according to the Freddie 1991 mark, which can be calculated as how the best detention time for volume or the bitter lemon Well, if in this class, it's

more as an introduction from this liquid water treatment technology, the introduction component for the delivery. If the details are later, there will actually be calculations, there are calculations, there are designs to make the installation of this wastewater treatment. That will later be included in the curriculum for wastewater treatment planning.

Yes, that's why the installation planning for the installation of the water treatment plant will be included in the study plan for the installation of the water treatment plant. Usually, after entering the equalization, there is the first stage of restoration. As I have said, the first stage of treatment is more physical here.

This is the first stage of processing from the collection of inlet, network, passive field, equalization, then the first generation This is indeed more physical, physically, physical processing, if here it has entered the second stage of biological processing, if the first generation has been

In this first evaporation, the function is of course mainly the content of suspended solids in liquid water. So to reduce that content, then evaporate discrete particles through free evaporation and reduction of BOD, COD from liquid water. Well, this is more like suspended solids and discrete particles, so particles that can evaporate

individually, it doesn't have to be formed into a cluster like antiflocculation coagulation, if possible, the particle system can be absorbed in the first absorption. Well, this is also the same later, what friends are calculating for

What is the basis of the theory of evaporation will be in the installation plan of the wastewater treatment plant, it will also be discussed how between the evaporation speed vs. the evaporation speed or vo or or later the efficiency will be seen later it needs to be calculated related to

the speed of the surface and the speed of the surface so that we get the optimal slope, the optimal slope, usually the first slope is shaped in a rectangular shape, there is also a circular shape, if we look up like this, yes, if we look up, the circle is like this, the side looks like this, so the water will enter here,

later there is a flow there, the speed of this surface flow and the speed of the vibration are not needed to be counted later, then after that, the wave will come out through here, here there is actually for the tool for the component for what sludge so sliding the sludge can be done if not usually if not mechanical this is made a bit slanted so that the sludge is

but still there needs to be a mechanical way to collect the slat here, after that the slat will be sucked out of the first irrigation. Then the circular sedimentation, there are actually various divisions or divided into other mechanisms, yes, this one, for example, is an influent or a liquid water that comes in from here, so it comes in from here,

Hi, this is the way out here, here, later, there is a bridge, yes, this bridge is like this, yes, the model is a bridge, later here, it will form a flow, maybe friends, there is a horizontal flow here, yes, if this is more of a radial flow, there is a radial flow, so it will rotate, so it will rotate so that the name will

the suspended solid or the particle that was discreet earlier can experience a collision then this is a pipe slot for the pipe slot for the spring or the one that has a collision earlier, the result of the collision earlier entered here if in the long term it will be on the wrong side

For example, near the input or the influent, the liquid water enters, there is for collecting slat or sludge or the result of the evaporation, and then it will be thrown away. Later, the liquid water that comes out of the first evaporation is expected to have reduced the suspended solids, the particle discrete, BOD and COD. To be done,

the next stage of the process. Alright, friends. That's all I can say for this occasion. Thank you for your attention. And I'm sorry for all my mistakes and mistakes. See you again. Stay excited. Wassalamualaikum warahmatullahi wabarakatuh.
