Types of pollution

Pollution of ponds is divided into mechanical, chemical and biological.

Mechanical pollution is the accumulation in the pond of objects unusual for this environment. This category usually includes household waste.

Chemicals mostly dissolve in water, getting there in a liquid state or in a solid state.

Biological pollution does not have an unambiguous concept. Pollution is a large accumulation of microorganisms in the lake. Numerous occurrences of various bacteria in the lake can also be attributed to biological ones.

In the photographs in the article, we can observe a reservoir polluted with mechanical debris.

Methods for getting rid of debris in the pond

Water treatment methods include five methods.

Mechanical cleaning method

Cleaning the bottom of large reservoirs is carried out by a special dredger. The dredger can collect silt deposits from the bottom of the reservoir, thanks to a powerful soil pump. Under pressure, sludge at the same time as water is fed through a pipeline system to specialized silt pads.

These maps are created before cleaning the ponds, this is an area that is fenced with a rampart on each side. Its scale should directly depend on the amount of deposits that are going to be extracted.

Long before the start of work, they study the object of the soil at the bottom, remove large debris, metal objects in order to avoid equipment breakdown. After that, they create a project on which the next work will be carried out, taking into account the smallest details.

The necessary materials and equipment are delivered to the place of work. A piping system is being installed that leads to the map from the reservoir. After all of the above manipulations, cleaning can begin.

Biological treatment

The basis of the method are microorganisms, which, being in special containers, clean ponds and other water bodies. In small reservoirs, special preparations are used, the basis of which are the capabilities of various bacteria.

Also, powder can be sprayed onto the water or a special solution can be added. The introduction of such substances increases the level of water transparency several times, due to the accelerated decay of rotting algae, the decomposition of the dead inhabitants of the reservoir.

Using such preparations to prevent various pollution, it becomes possible to completely stop the processes of humus of natural substances in the reservoir, the same applies to the formation of sludge.

Chemical cleaning of reservoirs

The basis of the method is the addition of special reagents, diverse in composition, to the reservoir. They help keep the acidity of the water at the right level for the owners, and are also involved in the decomposition of rotting algae.

Dry cleaning is a very effective way, however, it should be understood that in this case, strict adherence to the dosage is necessary. Large doses harm the health of the inhabitants of the reservoir, as well as the person himself.

Planting useful plants in a pond will help you avoid the use of chemicals, they saturate the water with oxygen, they are called «Plants — oxygen generators.» Such a plant is a swamp.

Sorption method

It also uses special minerals zeolites. They are placed in a specialized net, after which they are laid in a pond. These minerals, in turn, rid the water of excess ammonium and phosphorus, after which the water reaches the desired chemical balance.

UV cleaners

Purification of water from viruses, microalgae and bacteria is possible only with the help of this method. The basis of this method will be the impact of ultraviolet radiation on harmful organisms, while stopping their reproduction and growth.

For large ponds, two or three ultraviolet cleaners are installed. Inside the ultraviolet purifier is a lamp that is completely isolated from algae.

This type of cleaning is very useful for swimming pools, as it reduces the level of chlorine in it by twenty percent.

The main signs of pollution of the reservoir

• The water changes color and becomes less transparent. Water loses transparency, usually due to an excess of sand or clay that has entered it. The color may change due to the multiplication of various microorganisms in the pond.
• Bad smell. The pond begins to smell unpleasant, this is due to the reproduction of fungi and bacteria.
• Various plants grow abundantly in the pond.

These signs should be a signal that it’s time to clean the pond. Otherwise, a neat little pond will gradually turn into a green swamp.

Complete water change

If repeated attempts to clean the pond do not give the desired result, this reservoir needs a complete replacement of water. All inhabitants for this need to be moved to a safe place, then drain the water and begin a complete internal cleaning of the reservoir.

The transparency of water can be determined by the folk method, take a snow-white plate and lower it to a depth of about 10 centimeters, if the plate is not visible, then you urgently need to change the water.

Cleaning silt deposits at the bottom of the reservoir is almost the main problem in this type of cleaning, it is necessary to prepare a specially designated place where you will collect silt deposits. Everyone knows that this place will no longer be fertile for other plants, due to the special composition of the silt.

Regular extra care

In order to avoid rapid pollution, and subsequently the cost of a complete cleaning, it is worth regularly maintaining the appearance of the reservoir in a neat condition.

It is recommended to purchase a telescopic pond net and daily clean the surface of the water from debris, leaves and other objects that have accidentally entered the pond. This will noticeably improve the appearance of the pond and significantly slow down its pollution.

In autumn, as soon as leaf fall begins, you can stretch a special net over the pond, the density of which is from one to two centimeters. Its function is to protect the pond from getting dry leaves and branches into it.
