1. Efficient treatment of different paint types (oily & watery).
2. The water quality after treatment is clear and odorless, which can be used for a long time.
3. Device fully automated, eliminating the need for dedicated management operations and saving labor costs.
4. There is no need to clean the pool regularly, no need to stop the clearing pool, effectively reduce the cost of clearing pools and increase the effective production hours.

Taking the C-line of CITIC Daika Qinhuangdao as an example, due to the serious problem of spraying the slag pool and the slag reduction and waste reduction on the spraying plant, according to the current problems, it is proposed to establish a set of NPS equipment. The recycling of the slag pool and the reduction of the paint slag are treated, and the waste water containing the waste paint slag generated in the spraying system is reused to achieve the requirements of zero discharge and large reduction of paint slag. To meet customer production line requirements. The processing capacity of the device is 10T per hour. Achieve the effect of zero emissions, waste reduction, cost reduction.

A car factory with a paint capacity of 25 tons per month will cost 5000 yuan per ton of paint residue.

The monthly paint disposal fee is:

Monthly treatment amount of paint residue: 25,000KG/2*35%*70%*55%/(1-0.9)=16,850KG

Monthly treatment cost of paint residue: 16,850 /1,000*5,000 yuan = 84,250 yuan

Using NPS devices:

Lacquer treatment cost: 3,370/1,000*5,000=16,850元

Save annual costs: (84,250-16,850)* 12=808,800Yuan/Year
