Our company has developed a monitoring device capable of watching of wastewater treatment processes for their correct operations. Such equipment will prevent various accidents, and in wastewater treatment plants equipped with membranes, it will inform that the necessity of membrane replacements is nearing. In all such cases, the relevant operating organization will be notified in advance. The newly offered options are based on an information transmission system over the GSM network by SMS (short message service).


This low-costing option offered by our company is a system watching the blower function. If the pressure level in the inlet pipe leading to the aeration element drops, a countdown function will be activated and if (within a preset period) the pressure level does not rise back, the equipment will send a message to the relevant operating organization informing about the blower failure.

Installation conditions

The basic condition is obviously the coverage of the relevant place by the mobile network provider issuing your SIM card. This SIM card should be bought in the version/lump sum for GSM gate, in order to prevent its barring if the card is not used for a longer period of time (i.e. a period without any emergencies in the plant). Otherwise, the SIM card does not differ from standard cards used in our mobile phones. Another installation aspect is the need for 230 V power supply (6 to 12 V is also possible, 5 W absorbed power), but this condition is always met because the power is needed for the blower supply. In addition, at least 8 cm long hoses between the blower and the wastewater treatment plant will be needed.

This extended version is intended for wastewater treatment plants equipped with membranes, where - apart from the blower monitoring - the device can also watch membrane fouling, which prevents undesirable accidents. Due to this system, we are able to warn the operating organization about several critical conditions, namely:
•    too long intervals of the pump operation (as membranes are at the end of their ser-vice life, the plant is overloaded),
•    the plant is “full” (either membranes are clogged or there is a pump failure).

Installation conditions

The conditions are the same as in the previous case, however the float into the activation section must be installed or it will be necessary to use the existing one for cleaned water (permeate), provided that this is viable by the electrical panel layout and/or permitted by the operating organisation to make necessary modifications in the panel. However, the best solution is to buy this monitoring system completely together with the wastewater treatment plant and the device can be incorporated into the standard electrical panel.

Before the supply of any GSM type, it will be necessary to enter the phone number of the operating organisation into the system.
