Waste water disposal stations

measuring the amount of waste water delivered
by sewer sanctions machines
measurement of selected parameters
such as pH, conductivity, temperature, etc.
identification of waste water carriers by proximity cards
automatic recording of data on each waste water discharge
each plant version tailored to individual customer needs
cooperation with a computer
(e.g. invoicing, process visualization, etc.)
possibility of waste water sampling
possibility of setting quotas
possibility of installing a pre-payment system for waste water delivery
possibility of using solids shredders

Waste water disposal stations are used to collect municipal and industrial waste water from sewer sanctions machines. The stations allow you to specify the quantity of waste water supplied, its temperature, pH and conductivity. They identify carriers, as well as waste water providers. They also allow you to program a quota of waste water delivered.

Advantages of the STZ - type waste water disposal station:

protection of a waste water treatment plant against destruction of activated sludge (bed)
full automation and failure-free operation
high quality, durability and reliability
the container and metering skid made of stainless steel
cooperation with a computer
quick and easy installation
tailored to individual user needs and terrain conditions

Waste water disposal stations consist- among other equipment - of metering skid and control system. Our systems meet all environmental requirements and require no protection zone. At the request of our customers we are able to equip the station with a sand separator, grate, sieve, screening press, etc. The disposal station operates in automatic (maintenance-free) mode. The station equipment can be installed in various heated containers or buildings at the customer’s request.

We are here to help you solve any technical problems that may occur during the design, installation, operation and modernization of facilities.

Description and principle of operation for the station with a sieve and screening press:

The station measures the amount of waste water supplied, as well as other selected parameters, protecting against exceeding the assumed values (in accordance with accepted requirements).

Waste water reception begins by connecting the sanctions machine hose to the sewage collection system with the connector. The carrier identifies himself by a transponder badge. Then the gate valve is opened and waste water flows into the sieve with screening press. Solid pollutants flowing with waste water settle on the sieve. A ribbon feeder scrapes the screenings from the sieve and transports them to charging hopper of the screening press. The screenings are pressed and moved outside into plastic bags or containers.

Then the waste water flows through the flow meter sensor and measurement module, in which the measurement of pH, conductivity and temperature takes place. If the physico-chemical parameters of waste water supplied do not fall within the given range of values, the gate valve can be automatically closed and the waste water disposal will stop immediately. In such case the waste water sampling is possible through the sampling system, and the sample can be sent for laboratory testing.

Total amount of waste water delivered is measured by the electromagnetic flow meter.

After the waste water collection from one supplier the gate valve is automatically closed, and a valve of the washing collector opens to wash the system with water and thus prepare it for next waste water reception. All data is saved on a memory card.

Operation of the entire system is managed by the control panel with printer and reader to quickly identify the supplier.

After each waste water discharge you can print a supply report, which will contain, for example:
1. Supplier No.
2. Dates and times
3. Overall amount of waste water supplied during a day
4. Amount of waste water currently supplied
5. pH, conductivity and temperature values
6. Sample No. (in case of using the automatic sampling system)
7. Quota of the fixed amount of waste water for the Customer (if the quota has been fixed)
