To clean lakes are four basic methods: mechanical, biological, chemical and purification using UV radiation.
Mechanical cleaning involves collecting debris from the surface of the water with nets or special equipment, such as nets.Mechanical cleaning large bodies of water as possible using small boats and divers work.In recent years, the purification of water bodies have become actively involved and divers.
Purification is carried out in several stages.First, with the help of machinery, excavators dug drainage ditc
hes and an additional tank and drained water from the lake.Then clean the bottom, remove the garbage, sludge, bottom sediments, clean the lake shore from excessive vegetation, loose springs.Return water by mechanical filtration.It is the cheapest and most effective way to purify the water from the shallow organic matter and algae.
Artificial ponds and lakes on private land owners clean themselves.You can use a regular net, but for a deep cleaning - "underwater vacuum cleaner."The device also acts as a conventional vacuum cleaner, sucking up dirty water with bottom silt, algae, organic.Various attachments such mechanisms help to clear most intricate bottom topography of artificial reservoirs.All suck garbage collected in a separate tank to be cleaned during filling.
Besides mechanical treatment, can also produce and biological treatment of the lake with the help of biofilters filled with a porous substance that promotes the growth of aerobic and anaerobic bacteria that feed on organic matter, lingering in these filters.
Chemical cleaning is due to the addition of the water chemicals to restore the chemical composition of water and its oxygen saturation.This cleaning water must be carried out exclusively by specialists because it requires precise calculations.
purification with ultraviolet light is submerged in the lake lamps with UV light (wavelength 180-300 nm).Ultraviolet light affects the DNA of small algae and micro-organisms, bacteria and kills them.All devices are required to clean, are commercially available in specialized stores and organizations.
