LOWERING OF WATER LEVEL
FLEXIBLE NEEDLE FILTER SYSTEM
Simple and fast installation/disassembly, and transportation.
Due to the elastic material used in the production of needle filters, the risk of their damage during operation is minimal.
Needle filters are connected directly (without additional connections) to the collection manifolds, thus maintaining a constant vacuum in the system.
For work with needle filters, we use economical vacuum pumps that operate extremely quiet and the fuel consumption of which, with a vacuum pump capacity of up to 320 m3/h, is about 2.5 – 3.0 l/h, while the fuel consumption of conventional pumps is about 5.0 – 6.0 l/h.
This system is inefficient in clay soils with water-saturated sand layers.
VERTICAL BOREHOLE SYSTEM
Drainage of sufficiently large areas is possible with a relatively small number of vertical boreholes, so the system is very effective in draining large areas.
If one or more of the pumps of the borehole system fail, the system does not stop working.
It does not require much maintenance.
It is suitable for all types of soil.
It is one of the cheapest and most efficient ways to drain large areas (e.g., underground sites and construction sites, etc.)
The system is installed/disassembled using mechanization, so this system is not as mobile as needle filters.
