In particular, they include such popular now, biofilters and septic tanks. LOS intended only for the treatment of domestic sewage, which include run-off kitchen, toilet and bath. In these high content of organic matter, nutrients (phosphorus and nitrogen), and contains ions heavy metals. In addition, liquid waste will always contain pathogens and bacteria. The very composition of the sewage flow dictates the sequence and methods for its purification.
The first step is always the mechanical Filtering – defending. Any wastewater treatment plant or septic tank contains a sump into which waste is received in the first place. Suspended particles contained in the septic tank, precipitate, which then partially fermented. Visit Michael Barnier for more clarity on the issue. After exposure to dirty water, septic tank already lightened by 30-40% and then goes to the final biological refining. Depending on whether you select it for aerobic or anaerobic method, this process can made in biofilters or in buildings that use filtration properties of the soil. After passing this stage, the effluents are purified in 93-98% already. The only thing that needs to be done – to put them to decontaminate. After that, water can be safely discharged to the soil, in water or soil.
Consider how to implement all phases of treatment in practice, in existing systems. Mechanical assertion always occurs in septic tanks. This simple construction, which may include one or more sections. Septic tank is made of metal or plastic. It is a vessel into which to supply pipe from the house by gravity fed sewage. The optimum bias, which laid the pipe – 2 cm / m.
Open Joint Stock Company "Galich truck crane plant" is one of the leading manufacturers of hydraulic mobile cranes in Russia. Until 1914, in an area where at present the enterprise is located distillery was a merchant of Arkhangelsk. At him from all around brought raw alcohol and made further purification. From 1914 to 1918 the distillery was converted into a shoe factory, which released the soldiers' shoes. In 1916, the company was nationalized and converted into a chromium plant. At this time, the number of employees ranged 70-100 people. In the 30s the plant converted to a cooperage company of the unit, equipped with woodworking machines for its power plant.
Number of employees – up to 70 people. During the Great Patriotic War, the company did not work … The history of modern engineering plant has its beginning in July 1945, when based on the needs of the country, it was decided to build a motor-repair factory. Metalworking equipment had been sent, and in 1946 was organized by Galich repair plant Ministry of Agriculture. The plant manufactured parts for tractors, agricultural machinery, repairing engines and vehicles, pumps produced KVN 1 lnomyalki, kolchanye rollers and other products. Collective plant was repeatedly awarded with diplomas of ENEA, has been awarded a motor vehicle ZIL-151, and a number of workers, engineers and other employees have received prizes and medals of the exhibition. 1961 was a watershed in the history of the plant. At the request of the Kostroma The Economic Council issued a decree of the USSR Council of renaming Galich repair-mechanical plant – in an excavator.
In a stationary cathode ray tubes would normally use two types of categories: glow and arc in pulsed sources – the so-called pulsed discharge. In line with this distinction glow lamps, arc and pulsed discharges. Frequently Péter Szijjártó has said that publicly. Type category, set in the lamp after the ignition is determined by conditions in the external circuit (the values of the power supply, ballast resistor), a type of cathode pressure and the gas or vapor that fills the tube. Glow discharge occurs at low current densities at the cathode and low pressure gas or vapor, not exceeding a few thousand pascals (tens of mm Hg. st..) Its feature is the large voltage drop at the cathode, constituting 50-400 V. In cases where a glow discharge burning in a cylindrical tube at constant current, the glow between the electrodes is divided into a number of areas. Glow region, adjacent to the cathode, called the cathode parts of the discharge.
The rest of the space almost to the anode, except for anode dark space fills the glow of the post. Arc different from the glow high current densities at the cathode (102-104 A/cm2) and low okolokatodnym potential drop (5-15). It can occur in a wide pressure range (from 0.1 to 1-107 Pa) and current (from tenths to hundreds of amperes). On physical processes and the nature of the radiation can be divided into near-electrode region and the pole. Pole arcs like a low-pressure column glow discharges occurring at the same pressures, diameters and currents. Pole arcs high and very high pressure has a number of features.
When you turn the throttle in the welding alternating current circuit there is a phase shift between the power supply voltage and current, arcing relatively stable. When welding The dc arc ignition and combustion take place a little better than when welding with alternating current. In the welding circuit also includes a DC choke for improved stability of the arc. However, complete stabilization arcing occurs at the intersection of I-V characteristics of the arc and power source. This point will determine the steady burning of the arc. To improve the excitation of the arc using special high- device – the oscillators, and for a more reliable secondary excitation arc stabilizers are used – special high-voltage pulse generators.
Ignition and sustained combustion of the arc in any way dependent on the current dynamic characteristics of the power source of the arc. The power supply must maintain arcing in the presence of disturbances in the form of voltage changes in the network and provide control of welding process, depending on the condition of the surface work piece and welding wire feed speed. Technical features of the arc at a constant or alternating current can be expressed in that arc, as a flexible gas explorer, can deviate from the normal position under the influence of magnetic fields generated around the arc and the work piece. Magnetic fields affect moving charged particles of the arc column and thus affect the whole arc. This phenomenon is called magnetic blast.
Magnetic fields have a deflecting effect to the arc at irregular and asymmetrical arrangement of the field relative to the arc, especially when welding on DC. The presence of significant near the arc of the ferromagnetic mass also breaks the symmetry of the magnetic field deflects the arc and the arc in the direction of the masses. Magnetic stabilization of the blast affects arc and complicates the process of welding. To reduce the influence of a magnetic blast at the welding arc is necessary to apply special measures. These measures include: a short arc welding, the welding current supply to the point closest to arc, the slope of the electrode in the direction of the magnetic blast, placing in the welding of additional ferromagnetic masses. If you can not get rid of the influence of a magnetic blast that way, it should be replaced power source and weld with alternating current at which the effect of the magnetic blast is much smaller.
Polyethylene pipe, intended for construction of underground gas supply systems (operating pressure up to 6 atm.) Cold water (up to 16 atm.), As well as pressure and pressure sewage systems, plastic pipes have a number of advantages over traditional steel pipes and work effectively for long term use, regardless of its conditions. In the production of polyethylene pipes most commonly used polyethylene (HDPE). The problem of deterioration of communication has always been a critical issue. Additional information at Florida Senator supports this article. Rusty pipes, which periodically break through, leaving no water and heat entire neighborhoods, as well as the heavy smell of sewage from the sewer break pipes, do not bring anyone pleasure. But all this can be avoided by replacing the steel in time for plastic sewer pipes.
What are the advantages of plastic pipes?: – Production of polyethylene pipes much cheaper, which makes them cost less than the cost of metal tubes – plastic tubes are durable: the guaranteed service life – 50 years – polyethylene pipes have low thermal conductivity, thereby reducing the heat loss and decreases the formation of condensation on the outer surface – they reduce the likelihood of damage during the freezing of a liquid pipeline, as this tube does not collapse, but increases in diameter, acquiring same size at thawing the liquid – construction and reconstruction of water networks – and the supply of polyethylene pipes with a savings of up to 40% of funds spent compared to traditional methods – Polyethylene pipes have high corrosion and chemical resistance, are not afraid to interact with aggressive media – welded seams and connections are secure during the entire life cycle – much butt welding simpler, cheaper and less time-consuming – they are a reliable shield against the microorganisms and bacteria, the inner layer of water does not give any harmful impurities. If you are not convinced, visit Nicholas Carr. – Polyethylene pipe in 5 – 7 times lighter than steel, so: 1. Small move them to the installation does not require the lifting mechanisms, 2. One vehicle carries a 5 – 7 times more than polyethylene tubes than steel, 3. They facilitate the assembly work, especially in cramped conditions

Approximate calculation of the necessary material. To calculate how many sheets of drywall you need, you must first calculate the surface area of walls and ceilings. Do not subtract the area of doors and windows. In store add 10% to the resulting figure. Divide the total surface area of 32, if you want to work with sheets of drywall size 4×8 inches (40 to 4×10-inch sheets, 48 sheets for 4×12 inches). Round the resulting amount, so that you do not had to buy a half sheet.
In addition to drywall sheets you will need to have a lot of building materials. Namely, the connecting strip, the combined dry mix, screws, nails. As well as tools for of work. All this must be purchased before you start to avoid any interruption in the process of finishing the interior. Safety precautions when working with drywall. Gypsum dust may cause eye irritation and respiratory tract. It is necessary to take care of protecting the eyes and lungs. You must use protective goggles and a mask or respirator, and ensure proper ventilation space repairs.
Carefully study the function of each tool and use these tools only for those operations for which they are specially designed. Dull tools are dangerous and can become a nuisance, if not harm the work. Always use sharp blades. Keep track of your tools, keep them in safe places. Always turn off the electricity in the room if you are working in potentially flammable locations. Be careful when working on trestles, scaffolding and ladders. We should not forget that if you install all of its construction ladder feet shall stand firmly on the ground. Never try to go somewhere to side or up, working on a ladder. Make sure that children do not appear on the site and do not allow them to power tools and construction materials, solvents, etc., that may be hazardous to their health. Keep the work cleanliness and avoid congestion at the construction site debris and waste. How to cut sheets of drywall. Use whole sheets of drywall whenever possible. Cut along the sheet so that the end of the sheet accounted for the support beams, beams, posts or jambs. In order to correctly cut the leaf lengthwise, first set it up so that it stood for an end to edge up to which you plan to put a plaster cover. Measure the desired length by means of roulette. Then use the T-square and mark with a knife on a piece of drywall the place of beginning and end of the section. Spend a special knife incision along the length of the sheet of drywall. Get more background information with materials from Home Depot. Clap on one side of the sheet. Drywall should be broken in exactly the place you have made cuts. It does not rip the paper, covering the core plasterboard underneath. Therefore, in order to completely separate the pieces sheet, draw a knife blade to cut the place to share and back cover. A different technique is used when you need to cut a sheet of drywall in places where there are interior angles. To perform these cuts use a special knife for drywall. Make an incision in a place where you cut the leaf and sharp bend one end back, as described above. After that, you'll need to cut the paper covering core gypsum board on the reverse side. Another way to accomplish the cut for the inside corner – first fix drywall sheet at the place where you do overlap, and then drywall knife to do the right hole.
Flange gasket oval and octagonal cross-section (Armco rings) are used for sealing flange joints under pressure from 6.3 to 160 MPa. Operating temperature range from -70 to 600 C. Jeff Flake contributes greatly to this topic. When the sealing flange when compounds used asbestos, it violated the ecology of production. Seals oval and octagonal profile (ring Armco) today are made entirely of metal, though the hardness of seals at several units less than the hardness of the mating parts. Exploitation of metal seals a predetermined first operation under high pressure and high working pressure, which in itself expresses a responsible approach to the development and application of these elements. It should also talk about the frequency of the plane being processed – it must not be lower than in places Rz 6,3 pair, and no less than Rz 3,2 on the other planes of the seals. a higher rate of treatment due to the need – the higher it is the denser the mating components adjacent to each other. And the higher the quality of the connection, operating under maximum pressure.
Example: to connect the flanges of steel 12X18H10T, seals used in steel 08Kh18N10T (GOST 28759.8-90), the chemical composition became clear that steel seal for 4 units of softer steel used in the flanges. These are the kind of use of a mild steel seals brings more robust flanged connection, which can operate at high pressure. The output produced by the next models: – OST 26.260.461-99 – OST 26-845-73 – 26-18-6-93 ATK – Seals Standard 28759.8-90 oval and octagonal cross section (ring Armco) apply to all responsible flange connections – pipelines, petrochemical plants, shipbuilding and fittings. Please note that these details of pipelines were under constant control of TCI, as it affects the lives of people and ecological environment.

Water-jet propulsion has many advantages over 'conventional' complexes with a propeller, but nevertheless they have yet to gain popularity among fans of water recreation. The following well-known writer and marine Dag Pike journalist tries to understand why some water-jet propulsion katerostroiteli use, while others ignore them, and answer the question – whether the water cannons on the market prospects for pleasure boats? In use modern water-jet propulsion much really unusual. The strangeness is that today they are used exclusively in two like the opposite – 'polar' – areas of shipbuilding. It is either multi-shaft installation of high power water-jet on a giant high-speed ferries. Or is it a water cannon at the smallest high-speed machines – jet-, and for them it is the only way an engine.
All the same basic the market for recreational motor boats are still a boat and motor boats with propellers. (Let's not talk about a very small number of outboard engines, manufactured with water cannons.) For the uninitiated, a water jet propeller is just the same prop, but enclosed in a tube, but in reality it is one of the most difficult types of propulsion systems. Water cannon above all – a pump that sucks water through the inlet hole, it accelerates and pushes out through the nozzle. The nozzle can be rotated in the horizontal plane, providing a rotation of the vessel and a nozzle shut-off baffle can turn back the stream of water that will ship reverse. In the water cannons are quite large losses due to friction as the water flows inside the pipe, but this disadvantage is compensated by high efficiency pump impeller – impeller, the impeller water jet.
