I don't understand who came up with the idea of ​​making ventilation from sewer pipes? I explain why I went the other way

Features and optimization of industrial wastewater treatment

A significant part of production with volumetric water consumption uses water from surface water bodies or wells. In the stepwise system of technological water treatment, industrial filters are used to purify water from various impurities and contaminants:

  • solid inclusions;
  • excess iron;
  • hardness salts;
  • organic compounds;
  • oil products ;
  • nitrates and nitrites;
  • viruses and bacteria.

In some cases, the specificity of production does not require such a deep inlet treatment, which is necessary for the subsequent discharge of used water into sewers or open water bodies. Reuse of treated wastewater in such situations is cheaper than waste water treatment and primary water treatment due to the elimination of some treatment stages. The similarity of the used equipment and consumables allows you to further reduce the costs of packaging and maintenance.

Wastewater treatment technologies

In most cases, modern wastewater treatment technologies are the same as for water treatment of the initial liquid from the water intake. The peculiarity of effluents consists in the point adjustment of indicators or the removal of individual impurities. Thus, in metallurgy and metalworking, magnetic separation is widely used to capture paramagnetic and ferromagnetic substances. Filtration of particulate matter using sand and other granular media is common to most industries.

In general, the water treatment chain for circulating water supply is shorter than for primary treatment. The same destructive and regenerative methods are used, in which the substance is either removed from the effluent without changing the chemical composition of the water, or forms another compound. But in some cases adaptation, revision, modification of basic technologies is inevitable.

Wastewater treatment plant

For the processing of household wastewater, complex structures are used, the elements of which include:

  • sedimentation tanks, where suspended particles are stratified. Those with a high specific gravity fall out in the form of a sediment. Foreign elements, which are lighter than liquid, go into the surface layers;

As a self-builder, I am always attracted by any non-standard solutions during construction. But some of them are not clear to me at all.

Friends, hello everyone! The construction of my house is moving forward, and at the same time I need to delve into new construction processes.

Now the next step is the arrangement of my small basement, and first of all, I decided to make normal ventilation for it.

All mortgages were made in advance, in the foundation slab

Therefore, this work should not cause any special labor costs. Most of all, I was asked questions about the various options for execution, which I came across on the Internet.

Especially very common sewer ventilation

At first, when I saw this, I became interested. "Probably it's cheap, simple and reliable" - I thought, otherwise why are there so many examples of this option.

But compared with standard ventilation ducts, I was surprised

✔ I started with the price. The usual self-builder approach ????.

This is how much ordinary gray pipes cost, 110 mm in diameter.
