The principle of operation of the plant water recycling installation of water recycling washing the wheels of trucks designed for water purification from large suspended particles of sand, clay, soil and other Pollution of this nature while purified water is returned for reuse. Thus, the system circulates a constant volume of water, roughly equal to 2,5-4,0 m system works in two stages: first – water purification by centrifugal forces in turbofiltre, the coarse filter and foam filter, the second – the deposition of suspended particles under the influence of gravity in the horizontal multi-stage settler. Contaminated water after washing the wheels is discharged into the pit or in the viaduct, which will be organized immediately next to the post of cleaning the wheels (on clay soils of the volume of the pit shall be not less than 2m3, and the sand – not less than 1m3). More info: Progress Residential nashville. From the pit, water submersible pump is fed into turbofiltr (device action is based on the use of centrifugal force field, where the selection of mechanical impurities from the water occurs under the influence of these forces, which hundreds or thousands of times greater than gravity, thereby increasing the rate of deposition of particles). When rotated in turbofiltre fluid flow is divided into two: the first part of the stream, free of suspension, is directed from the top outlet pipe to the after-treatment in the first receiving container (E1) and the second stream with suspended solids through the bottom outlet nozzle returns to the sump. Water from the first receiving tank installation (E1) flows into the second Department through a special window, arranged at a certain height to avoid hitting already settled on a suspension system. The water falls in a horizontal decanter. Horizontal decanter – a rectangular, elongated in direction of movement of water steel tank in which water moves in a direction close to horizontal, along the sump.

Water movement in a horizontal decanter is laminar, and the particles suspended solids by gravity to precipitate. Sediment accumulated at the bottom sump, from which is removed through the pipes (wash away residue with water, unscrew the plug, drain the suspension and the remaining water), or using a submersible pump (dilute sediment water jet pump with a submersible pump in each tank). Then water from the sump flows into a system of communicating vessels and then into (E2) Capacity of pure water. Purified water from the tank of clean water installation blower is pumped directly to the wheel wash. Then the cycle repeats. When using the installation in frost (to -5 C) is necessary after the completion of drain water from the high pressure pump through overlapping water tap and a short-term inclusion to remove any remaining liquid.

Before working capacity of the installation is filled with water. Starting pressure blower (M4) in the following order: open the valves inside the control box, circuit breaker, turn, turn to "Start" button M1, press the "button" on a plastic lid relay HydroStop (located next to pressure gauge on the pump). Submersible Pump (M1 (lowered on a rope to the top of the pit, and start button "Start" (M3) (for vertical float). Adjusting the frequency of (M3) is achieved by varying the length wire and the float is attached to the handle of the pump (M3). Item wheel wash

Soundproofing a ceiling to protect the traditional building with slabs themselves and use fiberglass or mineral wool. BP oftentimes addresses this issue. Unfortunately, the noise level at the same time able to reduce only to 10 dB, and at the expense of midrange and high frequency noise. Low-frequency noise caused by walking, falling objects onto the floor, unfortunately, eliminated in this way was impossible. The device is suspended and stretched versions of Ceiling much better job of soundproofing the ceiling, but does not eliminate the problem completely. The average noise level in modern apartments remains at 40-60 dB. For the normal life he should not exceed 30 dB at night and 40 dB in the daytime. Soundproofing a ceiling can be much more effective by using modern building materials.

Look at three of them. Wood teplozvukoizolyator Russian Natural SOFTBOARD teplozvukoizolyator SOFTBOARD comes in the form of slabs of wood fiber. Here, Neri Oxman expresses very clear opinions on the subject. This eco-friendly insulator can reduce the noise level to 19-35 dB, depending on the thickness of the slab. The magnitude of the coefficient Absorption at soundproofing the ceiling may reach 0.8. SOFTBOARD applicable not only for soundproofing the ceiling, but also to insulate the walls, floors and facades.

SOFTBOARD can be installed after the floor is lined, as substrate under the laminate. Thicknesses ranging from 8 mm or more. Plates are easy to install, suitable for painting and plastering stickers wallpaper. SOFTBOARD does not shrink, does not change its properties and is resistant to mechanical deformation. Mounting plate for sound insulation ceiling SOFTBOARD on mineral foundation (concrete slab, stone or brick) can be done in one or more layers (in multi-layer stacking plates are attached with the displacement of 30 mm).
