How to Choose a Qualified Water Treatment Rectifier

It is well known that ocean ballast water is usually treated by electrolysis and physical UV filtering. The two methods have their advantages and disadvantages. The UV method is simple and small in size, but it has the reactivation phenomenon and needs to be treated twice. The electrolytic method is more effective, but the treatment process is complex and bulky. Pass in water 1000-1500 cubic meters of below, more use ultraviolet method, above use electrolysis method.

Today we focus on the electrolytic ballast water treatment system, the supply of DC electrolysis rectifier, what needs to have?

1. A very rugged and reliable rectifier is the pre-condition.  

2.Standard modular cabinet structure: The inner components are standardization; installation standardization becomes simpler; Water cooling system doesn’t need external condensers and circulating water tower, water cooling pipe and heat sink integrated mold, water cooling pipe and transformer integrated mold. The utility saves the time of assembling and also avoids the potential danger of water leakage due to potential poor assembly.

The standard Modular cabinet structure makes the machine more compact, smaller in size, and space-efficient.

What’s more, the modular structure ensures the rectifier long working time. If a single module in the rectifier were to encounter difficulties, it can be easily plucked out and replaced by an onboard spare cabinet. The modular power cabinet ensures that your last water operations are uninterrupted.

3. The ballast water treatment system must require the rectifier to have an excellent waterproof function, the rectifier must meet the IP56 standard.

4. To Be Safe:

There is a leak detector that alarms automatically. And water leakage protection cut-off rectifier automatically.

There should be over-current over-voltage protection, phase loss protection, over-temperature protection, short-circuit protection, overload protection, etc.

4. Easy to use:

The rectifier has a nearby panel operation: Output Current, voltage, voltage, current mode selection. There is a working display, a failure alarm, etc.

What’s more, a remote computer automatic control system could be realized through analog signal 4-20mA or 0-10V control, or through RS485 communication protocol.

5. High power factor, high efficiency, save energy is necessary.

It is found by our customers that our rectifier fully complies with all the above standards. Also, the rectifiers can be customized according to the specific needs of customers.
