Wastewater treatment plants

Precistac septicke jameOur company Čabar Plast with its partner from Croatia has developed unique small composite systems for wastewater treatment – wastewater treatment plant of 4-50 EC (population equivalent).

In addition to small compact system systems, the company can also offer larger wastewater treatment systems for a larger population for hotels, settlements, residential buildings, from 50ES to 2000ES.

Wastewater treatment plants aim to remove as much matter as possible, ie. wastewater pollutants, using one or more treatment processes. Čabar Plast sewage treatment plant finally gives crystalline water with 99% purity..

During the sewage treatment process, a certain amount of sludge is generated, which must also be treated by certain procedures.

Throughout history, the aspiration of man has been the advancement of man and lifestyle, which has gradually led to negative impacts on the environment and his living environment. Each type of pollution emitted reaches groundwater, rivers, lakes and seas and is a global problem.

Water pollution flows into surface and groundwater streams. In order to perform water filtration, oxygen availability is of paramount importance. Rivers carry out natural water purification due to the action of rocks and rocks in the bed. In this way, the oxygen necessary for its filtration is obtained. This example of natural collaboration in the purification process produces crystal clear water.

 

Wastewater treatment plants (Biological septic tanks) advantages over conventional septic tanks are:

  • High degree of purification – at the exit of the system crystal clear water is obtained which can be used for drainage, Irrigation, it is safe for discharge into watercourses…
  • Sludge removal is done once in a period of 1-3 years, which is a great saving compared to classic septic tanks, which must be emptied several times a year.
  • No odors are present in the area of the wastewater treatment system.
  • Small dimensions.
  • Small investment and operating flows.
  • Fully automatic plant operation.
  • Maximum safety at work.

Wastewater treatment plants – description of system operationWastewater treatment plantsPrecistaci otpadnih voda

The plant operates on the principle of activated sludge. Pollutants are removed from wastewater due to biodegradation of organic matter by micro-organisms and which convert organic matter to biomass. The activity of the micro-organism is maintained by the addition of oxygen by means of a compressor during the aeration (device operating phase). The residual sludge that is obtained during the purification process is stored inside the tank or in a separate chamber – sludge tank.

The main characteristics of the Čabar Plast treatment plant (ecological septic tanks) are:

  • Using one tank for the purification process.
  • One day cycle of SBR work.
  • The duration of the SBR cycle is 24 hours, ie one SBR cycle per day. Wastewater treatment plants cover the average daily activity of a family or business organization. The sedimentation or resting phase is carried out in the late evening when the wastewater inflow is expected to be reduced (at night), ie when the wastewater flow is small.

SBR Wastewater Treatment System Phases – Wastewater Treatment Plants

  1. Pouring sewage into a biological septic tank – sewage flows in and flows freely into the reservoir through a pipe for uniform flow. The size of the inlet pipe is in accordance with the existing pipes installed in the building (house, hotel…)
  2. Aeration – During the process of arming, oxygen intake through the control panel is intensified. Bringing the oxygen-aeration is performed alternately with the resting phase, in order to support the biological process, the duration of the aeration phase is 5 minutes.
    Turbulence caused by the rise of oxygen bubbles mixes the contents inside the reservoir and dissolves the organic matter. Pollutants have been removed from wastewater due to aerobic biodegradation of organic matter whereby it is consumed and converted into biomass by floating microorganisms.
  3. Sedimentation – is carried out in the late evening when the expected inflow of wastewater (at night) is expected to decrease. when the wastewater inflow is lowest.
  4. Discharged treated water – After 75 minutes from the end of the sedimentation phase, treated water is pumped from the reservoir through the system.
  5. Sludge disposal – sludge treatment – if there is a special chamber or tank, sedimented sludge residue is pumped out of them. The sludge storage can be located inside or outside the tank. After filling the sludge tank, the mixture of water and sludge is placed on the surface of the previously thickened sludge. Excess water is recycled through sewage in the wastewater treatment process.
    The remaining sludge solidifies (clots). Alternatively, if there is no sludge storage in the tank itself, then it is recommended that part of the contents be removed from the tank – when the sludge volume (SV) is greater than SV30 greater than 700mg / l (when removing the sample from the tank after 30 minutes, if the sludge volume is greater than 700mg per liter, sludge should be removed).
