Water and sewage treatment plants


Biological wastewater treatment involves the increased intensification of biochemical processes of decomposition of organic substances occurring in natural conditions by using appropriate technical devices and creating optimal conditions for the development of a limited group of living organisms, which are a part of the natural environment.

NavoTech offers technical advice and assistance in selecting the appropriate wastewater treatment technology adapted to the needs and local conditions. We provide comprehensive design and construction solutions for wastewater treatment problems, out of concern for the protection of the natural environment...





Water and sewage pumping stations


In catchment systems, where there is no possibility of gravity discharge of the medium and there is a need to raise it to a higher level, NavoTech's NAVO water and sewage pumping stations are used.

NavoTech pumping stations operate in the range of flows from the lowest (where the lower limit is limited by maintaining the flow velocity in the discharge pipeline) to several hundred l/s. The pumping stations operate as two, three or even four-pump systems. With the highest flows, they are installed in two tanks acting as a system of communicating vessels. All materials used in the pumping station are adapted to work in an corrosive environment...



Rainwater management


What is the NT-ZWD system manufactured by NavoTech?

It is a complete, integrated rainwater management system. It is an effective solution to the problems of managing rainwater drained from the roofs of buildings,and also rainwater collected from paved surfaces (terraces, parking lots, streets, etc.).

The NT-ZWD rainwater management system is configured, selected individually according to the size of the catchment area, the investor's needs, and project requirements. Delivered to the site as a whole system with refined technical parameters, dimensions and a 10-year warranty for the Ordering Party...





Oil separators


The beginning of NavoTech's activity was primarily the production of petroleum separators, and up till today several thousand devices (coalescence, lamellar, vortex separators) have been produced.

The series of light liquid separation devices are tested according to the PN-EN 858 standard procedure at the 150 l / s testing station built on the premises of NavoTech. Process efficiency of the separation of pollutants and hydraulic efficiency are tested, we define in detail the height of the overflow thresholds on storm overflows ...



Fat separators


LIPO fat separators are installed in places of their excessive formation, e.g. in bars, restaurants, mass catering points, in meat and food processing plants, etc.

Natural fats are a mixture of glycerol esters and higher fatty acids. They are available in solid, semi-solid and liquid states. Fats are divided into two groups: animal fats (lard, butter, tallow, blubber, etc.) and vegetable fats commonly known as oils (olive oil, rapeseed oil, sunflower oil, linseed oil and others)...





Settlers


Suspension settling tanks are devices for separating and precipitating easily falling suspensions from sewage. In the simplest terms, the operation of settling tanks is based on holding wastewater in slow-flow conditions, thanks to which there is a gravitational separation of two phases: water and suspended particles.

The dimensioning of the settlers is to determine the required usable area, taking into account Stokes law. The depth of the settler is irrelevant. Only the surface of the settling tank is decisive in relation to the flow rate...



Drainage chambers


NT-BAS drainage chambers (tunnels) are the best solution for rainwater management with the possibility of using various solutions and combinations: drainage - retention - storage.

Drainage chambers (tunnels) manufactured by NavoTech are intended for the installation of management (non-pressure distribution, storage, retention and / or drainage) of rainwater drained from the roofs of buildings through gutters and downspouts, or collected from paved surfaces (terraces, parking lots, streets, etc. .).

The National Technical Assessment KOT has been issued for the NT-BAS drainage chambers...





Anti-flood protection


Anti-flood protection is used in places where there is a risk of water backflowing into the gravity sewage system from drainage ditches, rivers, lakes, bays or other water reservoirs. The backflow of water to the gravity sewage system leads to flooding of garages, basements and industrial plants. A frequent cause of flooding of lower-lying places are failures of water and sewage pumping systems. A proven anti-flood protection system is the use of flaps and non-return valves for installation on the sewage network or at their outlets to the receiver well...

Anti-flood protection offered by NavoTech includes:

- KP backflow preventer
- ProFlex one way check valves



Retention and storage tanks


Depending on the needs and conditions of use, NavoTech storage tanks are produced in various material and construction versions: cylindrical, vertical and horizontal, single or multi-chamber, as flow-through and non-outflow devices, with side inlet or outlet, and with additional inlets. Tanks are intended for underground construction in green areas or communication routes or as free-standing.

NavoTech tanks are used for: storage, rainwater retention, systems of sewage treatment plants, separators, settling tanks, drinking water storage tanks, fire tanks, use in open technical and industrial installations...





Fire-fighting water tanks


Technological systems of fire protection systems are built on the basis of ROK-PE polyethylene tanks or ROK-R steel tanks. Fire systems consist of one tank, or in the case of larger technological volumes, it is arranged in tank batteries with a capacity of up to 1000 m3.

The tanks are intended for installation in green areas or in traffic routes with a high volume of traffic...



Acid neutralizers


KPH acid neutralizers manufactured by NavoTech are used to neutralize acids contained in wastewater and are intended for installation in chemical laboratories or on sewage approaches to rooms where there is a risk of mineral acid spills, e.g. battery rooms, laboratories, etc. The proposed KPH neutralization system is also used as a condensate neutralizer. Sanitary and rain sewage should not be introduced into the neutralizer...





Flow regulators


DRP NavoTech rainwater flow regulators, due to the irregular nature of rainfall and the related flow changes, are mainly used in the construction of rainwater sewage systems, where the installed water and sewage treatment devices may be exposed to periodic hydraulic overloads that may cause them to malfunction or become damaged and thus contaminate of the environment. This problem can be solved by the use of retention reservoirs, NT-BAS drainage chamber system and overflow systems equipped with DRP flow regulators...



Pool pre-filter


Pool pre-filter, pump pre-filter (also known as 'hair catcher') is used wherever free-standing circulation pumps come into contact with an increased amount of solid contaminants, in particular 'fibrous' ones that can rotate on the moving parts of the pumps...





PE welding rod


NavoTech offers you a PE welding rod made of High Density polyethylene (PE-HD) by NavoTech with a circular cross section of 3-5 mm. This wire is used in welding, renovation, repair of tanks, pipes, pipelines, plastic structures and other elements made both in production halls and 'in the field'...
