Phosphating Bath Filtration

Phosphating is an important stage in metal finishing line. Due to the chemical reactions, insoluble particles are continuously formed in the processing bath. A contaminated bath leads to inconsistent conditions, poor quality, rejections, high maintenance and downtime.

We have a wide range of phoshating filters. (2) KOBELT-RFM-20 and (3) PhosphoFil+ are some of them.

Common *salient features of our Phosphating filters are

• Give complete process control of phosphating which is a production person’s dream.
• Directly improve quality of bath – direct connection
• Keeps phosphating baths in good condition always.
• Clear filtrate and highly dewatered sludge.
• Special dissolved iron removal accessory on request.
• Reduces cycle time and increase production.
• Compact
• Reusable filter media
• Leads to improved performance of heat transfer equipments.
• Reduce choking of spray nozzle, pipeline, pump and valves.
• Least o&m
• Reduced need for tank transfer.
• Reduces load on ETP and sludge disposal infrastructure
• Helps meet ISO 14000, EHS and pollution control norms.

Degreasing Bath Filtration

This is another important stage in metal finishing line. The bath is alkaline. Metal bodies are processed in this to remove oil & grease. Foreign particles alongwith oil & grease get into this bath which are termed as contaminants. With increase in levels of contamination the bath needs to be discarded frequently. Baths are generally discarded well after toleration levels of contamination is past. Meaning production is made to work in unacceptable inferior quality of bath. .With every bath discard, generally leads to heat loss, cost of fresh chemicals, cost of discarding the bath and load of ETP. Inferior quality also leads to major quality problems and also may lead to job rejection

Conventional filtration can not provide answer. As the solution is alkaline, heavy foaming takes place even with slightest agitation. Oil & grease further complicate filtration as they form thin layer on filter media and clog further filtration.

We have developed

KOFILDG

• This also confirms to our machine making principals.

• Is fully automatic and compact.

• There are no recurring cost of filter media.

• Remains un-affected by oil & grease presence.

• Constant filtration flow over very long period of time.

• Maintenance free machine.

• Separates out foreign particles and free oil separately.

• Bath is maintained at very good quality level always.

Degreasing liquid from the bath is pumped KOFILDG. First solution goes into free oil & grease separation section which is discharged out. Further it enters muck separation section. Clarified liquid is returned back to the degreasing bath. Muck is discharged out periodically without stopping filtration. The entire system is controlled by state of the art instrumentation technology making it completely supervision-free.

It comes in various sizes to meet all the needs of metal finishing industries.
