Productivity Increase & Waste Minimization For Electroplating Units

Chemical bath life enhancing Equipments

Total Oil Sludge (TOS) separator

To keep the soak bath consistently clean by removing oil & sludge continuously while extending bath life to more than 18 months. Since oil removal is total defects are reduced by more than 80%.

"You can make a poor coating perform with excellent pretreatment, but..... you can't make an excellent coating perform with poor pretreatment.

More than 40 equipments supplied so far.
Chemical saved 50%. Saving that much pollution problem.

On line Phosphate sludge separator

Source separation of the phosphating sludge, so that bath life increases. This equipment is attached to the side of the main equipment and removes the sludge on line. Hence we don't have to shut down the operation every week for cleaning up. There is no Monday quality and Friday quality.

More than 25 equipments supplied so far volumes ranging from 1-10m3 tanks.

Chemical saved 20%. Productivity increase 30%,saving that much pollution problem.

On line Acid smut cleaning separator

This equipment is attached to the side of the main equipment and removes the smut or the particulates from Phosphoric Acid/ Hydrochloric acid/sulphuric acid on line. Hence we don't have to shut down the operation every week for cleaning up. There is no Monday quality Friday quality. Removal of this sludge improves the life and productivity of the bath.

More than 25 equipments supplied so far volumes ranging from 1-3m3 tanks.

Chemical saved 20%. Productivity increase 30%, saving that much pollution problem.

Rinse water recycling Equipments

Using unique pumps we have developed, we could transfer the rinse water from final rinse tank to acid rinse and then to alkali rinse with the air power from the side channel blower. We could cut the rinse water use by one third. We have had cases where we have reduced it by half. This will also reduce the chemicals used for neutralization. Please refer our ten point programme for details.

We have implemented this systems in over 10 factories.

Reverse Osmosis system to recycle the water

With chemical bath segregated, oil removed by the TOS separator, it is very easy now to recycle the water using RO.

All the above systems have been Already implemented in leading auto-ancillary units in Chennai.

10- Point program to minimize waste from surface finishing process -Road map to zero waste plating operation.

Drag out Management

• Reduce drag-ins & drag -outs
• Segregation of the solid waste at the source

Rinse water management

• Rinse water recycle
• Rinse water segregation
• Rinse water ETP design
• Rinse water ETP sludge reuse

Chemical bath management

• Chemical bath life enhancement
• Chemical bath-let out segregation
• Chemical bath treatment to reuse
• Chemical bath treatment to useful sludge

At present in many the surface finishing industries the following are the typical observation:

• Unmeasured quantity of rinse water used.. Sometimes ad'hoc measures were taken to reduce it, like installing a timer or throttling the    valve.

• No attention is paid to enhancing chemical bath life. chemical were thrown into effluent as a weekly or monthly routine.

• All the effluents were mixed making them lose the chemical identity. Because all the sludge's were mixed, they cannot be put to a    productive use.

• The effluent will invariably contain more than the permissible level of TDS and hence dilution is often resorted to, increasing the disposal    problem.
