Monoblok-T

Monoblok – T

  • biological wastewater treatment plant with an interrupted operation
  • consists of a levelling tank, SBR reactor and sludge tank
  • the operation is controlled by a micro computer with the option to adapt the treatment regime to the quality and volume of inflowing water
  • designed for capacity up to 500 EO

The TopolWater Company ensures high quality on the outflow (values BSK5 under 15 mg/l), nitrification, de-nitrification and the partial removal of phosphorus.

Advantages of WWTP MONOBLOK – T:

  • high quality of water on the outflow – with sufficiently designed BSK5 tanks the outflow is 5 mg/l and nitrification, de-nitrification and partial removal of phosphorus is ensured
  • fully automated operation with remote system, reduction of costs for servicing
  • high adaptability (it is possible to use the wastewater plant for transporting wastewater from septic tanks)
  • low investment costs
  • low costs for operation

Description of the technological line:

The wastewater flows into the accumulation tank which has at the same time the function of the 1st activation stage. In the case of installation on separate sewerage systems, it is not necessary to perform pre-treatment and the function is replaced by the 1st activation stage. For smaller sizes of wastewater treatment plants the levelling tank can have the function of a storage tank for excessive sludge from activation. For larger systems an independent aeration sludge tank is built.

From the levelling tank the pre-treated water is pumped to the SBR reactor. During the fulfillment of the reactor and after its filling, there is biological treatment during which the aerobic and anoxic conditions alter according to the character of the wastewater. The treatment cycle is terminated by the separation of sludge and the following separation of water by the outflow. This provides the impulse for further filling of the reactor and the cycle is repeated. The optimal volume of activated sludge in the SBR reactor is automatically kept by the sludge pump. After each cycle the preset layer of sludge is pumped either into the levelled tank or into the independent sludge tank.

In the case of insufficient inflow of wastewater, the system is automatically switched into the maintenance regime in which the control unit keeps the aerobic environment in the reactor. It assures the wastewater treatment plant is functional in the case of a longer interruption of wastewater.

    • TOPAS – Ultraviolet (UV) Disinfection

    The Need for Cleaner Water

    It is proven scientifically that 85% of child sickness and 65% of adult diseases are produced by water-borne viruses, bacteria and intestinal protozoa such as Cryptosporidium and Giardia. Inappropriate water treatment can lead to heath problems – hepatitis B, tuberculosis, meningitis, typhoid fever, tricomoniasis, and cholera, glaucoma, gastrointestinal pain, salmonella, poliovirus, and diarrhea. In North America, E.coli O157:H7, an extremely dangerous strain of E.coli bacteria, infects more than 80,000 people annually. Fortunately, E.coli O157:H7 is easily inactivated by UV light.

    Disinfecting your recycle water with ultraviolet light (UV) makes good sense. It’s environmentally safe, it’s well proven, and it’s the way of the future for water disinfection requirements around the globe.

    The Process

    Ultraviolet (UV) disinfection uses a UV light source, which is enclosed in a transparent protective sleeve. It is mounted so that water can pass through a flow chamber, and UV rays are admitted and absorbed into the stream. When ultraviolet energy is absorbed by the reproductive mechanisms of bacteria and viruses, the genetic material (DNA/RNA) is rearranged and they can no longer reproduce. They are therefore considered dead and the risk of disease has been eliminated.

    UV-rays are energy-rich electromagnetic rays that are found in the natural spectrum of the sunlight. They are in the range of the invisible short wave light having a wavelength ranging from 100 to 400 nm (1 nanometer = 10-9m).

    UV, like distillation, disinfects water without adding chemicals, and therefore possesses some of the same benefits as distillation. It does not create new chemical complexes, nor does it change the taste or odor of the water, and does not remove any beneficial minerals in the water.

    Ultraviolet devices are most effective when the water has already been partially treated, and only the cleanest water passes through the UV flow chamber. TOPAS WWTP uses both a biological process and a sand filter to clean the water prior to passing it through the UV light, to provide complete water quality solutions. Ultraviolet light is a natural, cost effective, environmentally friendly disinfection process for use in homes where healthy water is a concern.
