pH automatic neutirazation apparatus

Advantages

・Sophisticated design that does not give an appearance of neutralization apparatus.

・Space saving and weight reduction have been realized by re-examining shapes and materials.

・pH of discharged water can be kept in a memory, and the data can be collected  by using a personal computer at a later date. (Type that includes a pH memorizer as an accessory)

・A tank made of polyethylene that has excellent corrosion resistance and durability  as well as a pH meter, a pump, and a mixer employing a resin-made case are used.

・2 types of control are available: 2-point control for acid and alkali, and 1-point control for acid or alkali.

・ON/OFF control, time division proportional control, or twin timer control can be selected.

・Calibration of pH4 and pH7 is done by one-touch operation.

・A pH sensor of a KCl replenishing type is employed. pH measurement can be done with dirty waste fluid as well.

・A liquid level gauge is used that has no voltage alarm contact as standard specifications.

・The raw water pump can be chosen according to waste water (optional).

・We are also ready to provide custom-made products that suit customers' needs.

Applications

・pH neutralization treatment of drainage in a factory.

・pH neutralization treatment of drainage that has been used for cleaning of a  dialysis apparatus or inspection apparatus.

・pH neutralization treatment of drainage in an experiment.

・pH neutralization treatment of CIP drainage in a food processing factory, etc.
