WWTP Equipment

Control Unit

Control unit is equipped with a special program that optimizes the entire treating process based on the continuously measured amount of wastewater. It is a unique system and has the following advantages:

• Maximum electricity savings – the performance of the treatment plant (blower operation time) is continuously adjusted according to the amount of wastewater.
• When the inflow of wastewater is interrupted, the performance of the treatment plant is automatically reduced to a maintenance mode, in which the treatment plant maintains full biological function for at least 3 months without sewage inflow. This is an ideal system for recreational facilities, without the need for installation and setting of various timers.
• Ability to set the mode for wastewater with non-standard contamination (restaurants, etc.)
• Chemical dosing, precisely according to the amount of wastewater, where only the concentration of the chemical per 1 m³ of wastewater is set.
• Equipped with WiFi connectivity, which allows full control, setting, and status monitoring of the treatment plant via an app on a smart device (e.g., mobile phone, tablet, etc.)
• Any malfunction of the treatment plant is indicated by light, sound or SMS message (in the model with GSM).
• The control unit is ready for integration into a smart home.

Sand Filter

It is used for mechanical treatment of biologically treated wastewater. The sand filter is essential if the treated water is further used in the household (toilets, etc.) or for drip irrigation. It is a unique device protected by a European patent (EP). Due to the sand filter TOPAS treatment plants can stably achieve a treatment quality that is practically unattainable with conventional treatment plants. Its great advantage is that it is built into the treatment plant and, as part of the TOPAS system regime is automatically rinsed several times a day with the rinse water returning to the treatment plant.

The sand filter is a separate tank with an interbottom. A layer of about 30 cm of sorted water treatment sand with a grain size of 1-3 mm is placed on this interbottom. Water filters through the sand layer into the space towards the bottom of the sand filter below the interbottom, thus being filtered. The interbottom has holes smaller than the grain size of the sand. The pre-filtered water, free of fine undissolved substances, is pushed by hydrostatic pressure through the sand layer and the interbottom into the tank of filtered water from where it is pumped to the outlet.

During the sand filter washing, pressurized air is supplied under the interbottom, which passes through the filtration holes into the sand layer, stirs the sand and brings the turbidity to the surface. A part of the turbid treated water (about 10%) is then returned back to the accumulation.

UV lamp

UV lamp (UV) is a device in which a special lamp is placed which emits intense UV radiation when lit. Water is pumped through the unit where it is exposed to ultraviolet radiation which is deadly in large doses to most organisms and is used to destroy algae, parasites, fungi, viruses, yeasts and bacteria in water. UV lamp disinfects water and eliminates any present viruses and bacteria, the causes of diseases and infections. Its use is appropriate if the treated water is further used in the household (toilets, etc.) or is discharged into a natural pond.

GSM module

It is used for data transmission and remote management of the TOPAS treatment plant. Communication is carried out via SMS messages or the internet. The GSM module has the following basic functions:

• Provides error messages and information about the status and activity of the treatment plant
• Ensures the transmission of all data to the dispatch (service) center or to the phone numbers of the WWTP user
• Secures the adjustment of basic treating parameters set in the control unit
• Allows the installation of backup batteries
• Enables remote control of up to 5 user relays (230V)

Sludge Dewatering Box – Awarded the GRAND PRIX 2022 and INNOVATION OF THE YEAR 2022

The TOPAS WWTP assembly with a sludge dewatering box solves one of the fundamental and perhaps most important aspects of the operation of all domestic WWTPs. That is the control, thickening, volume reduction and subsequent removal or reuse of excess sludge with minimal maintenance frequency requirements. The main advantages of the sludge dewatering box are:

• Storage capacity for sludge in the dewatering box for more than one year
• The dewatering box can also be retrofitted to any TOPAS treatment plant
• The dewatering box can be installed by anyone according to the instructions for individual types of TOPAS WWTPs even without special tools

FOR ARCH 2022

At the For Arch 2022 fair in Prague Letňany we entered the sludge dewatering box into the competition for the most innovative exhibits of the fair. For the TOPAS WWTP assembly and the sludge dewatering box we received the main GRAND PRIX award.

INNOVATION OF THE YEAR 2022

The TOPAS WWTP assembly together with the sludge dewatering box was honored in the Innovation of the Year 2022 competition, annually awarded by the Association of Innovative Entrepreneurship of the Czech Republic. The competition evaluated the highest quality innovative products submitted by applicants based in the Czech Republic for the year 2022.

       

TYPES OF SLUDGE DEWATERING BOXES

STANDARD – a separate box that can be used for any WWTP for manual pumping using any sludge pump
SET MANUAL – a box for the TOPAS WWTP with manual filling – by manually turning on an additionally installed air-lift pump
SET AUTOMAT – a box for the TOPAS WWTP with automatic filling – by automatic switching of an electrovalve – using a control unit supplying air to an additionally installed air-lift pump
