SYNOPTIC OF WATER TREATMENT PLANT
AND ACID PREPARATION

Program realized on personal computers for the control of a sewage treatment plant for industry. In this instance the case of sludge for the treatment of water from the treatment of automotive batteries and the control of a plant preparation and storage of sulfuric acid.

the system was implemented by controlling a PLC GENERAL ELECTRIC®

PH-METRERS / ROX-METERS

• B70002

The instrument is equipped with a high impedance analog input for interfacing with the probe pH. The operator can set keyboard, digitally, 2 alarm thresholds associated with pH 2 outputs with the possibility to set a delay of activation. The tool checks the time to return pH and active alarm output. E 'have a 2-point calibration procedure of the probe. The tool can display, if enabled, the voltage of the probe, expressed in millivolts (+ / - 450mV rox-meter). An expansion card (option) allows you to mount a serial RS232 or 485 or exit 0-20mAmpere or 0-10V

pH-METERS FULL OPTIONAL

• C20003

The instrument is equipped with a high impedance analog input for interfacing with the probe pH. The operator can set keyboard, digitally, the threshold of restoration treatment (pH). Associated with the threshold there is the possibility to set a hysteresis operation and a delay of activation. E 'have a 2-point calibration procedure of the probe and a test verification exit operation. The inputs and digital outputs operate an automatic machine with two levels of treatment and reintegration product with two levels.

CONDUCTIVITY METERS WITH CYCLE FOR REGENERATION OF RESINS OR QUARTZ FILTERS IN AUTOMATIC

• C30001

The instrument microprocessor operates a production facility with demineralized water management 16 outputs programmable for 20 phases of work to be connected directly to a 24V solenoid. At each stage you can schedule a time to work. Status of the manual, automatic and alt allows the operator to start, resume, exclude or terminate the cycle at any time. The instrument is equipped with a reader of conductivity with the automatic selection of two cells of reading. Additional 4 Exit manage the restoration, the pump, alarms and the threshold of conductivity.
