MINI-FIX: the compact, fully automatic neutralisation plant for laboratories
Task of the plant
The MINI-FIX system has been designed for decentralised application below the laboratory table. Its advantages are a small footprint, easy operation, rugged design and optimal cost-benefit ratio. With the help of special electrodes and chemicals, the installation can also be used for cyanide and chromate decontamination.
Process description
The wastewater to be neutralised (pH 2–12) flows along an incline into the reaction tank. As soon as full contact is established, the neutralisation process is started automatically. The wastewater first is thoroughly mixed with a feed pump and the pH value is determined. Then the PLC doses acid or base, depending on the deviation from the permitted pH level. Finally the neutralised wastewater can be introduced into the sewers.With its extremely small dimensions, the MINI-FIX neutralisation installation fits in almost any laboratory wash cupboard.
