SCANPOL ® 15

Product description

FOR THE TREATMENT OF WASTEWATERS FROM METAL FINISHING AND PCB INDUSTRIES

 

SCANPOL® 15  PRECIPITATION AGENT has been developed especially for the treatment of spent rinse water, half concentrates and concentrates from metal finishing and PCB industries.

SCANPOL®  PRECIPITATION AGENT precipitates contamination’s and metals from the solutions. It is especially adopted for the treatment of spent solutions when low discharge of heavy metals is demanded.

The most suitable way to control the treatment is in proportion to the flow. It is very suitable for a through flow or a batch treatment plant for treatment of spent rinses contaminated with heavy metals and other types of process water.

The applications referred to are just a few areas of use for the product. Since the product is very versatile in a number of treatment areas it is possible that it has further potential applications of use which has to be evaluated based on the users demands and conditions.

The precipitated metals form stable flocks which settles very rapidly and are easy to separate.

 

PROPERTIES

 

Composition: Mixture of alkaline components

Description:             Slightly yellow liquid

Specific gravity:        1.12

pH:              above 12,3

BENEFITS

 

– The amount of sludge is significantly reduced compared to standard ferric chloride – lime treatment.

– The treatment time is very short.

 

EQUIPMENT

 

It is possible to treat most types of process water from  the metal finishing and PCB industry with SCANPOL® 15 in a waste treatment plant in batch or through flow mode.

For the treatment of process water it is recommended that the equipment for dosing of SCANPOL® 15 is controlled by time or flow. The dosing pump could be directly attached to the drums in which the solution is delivered or to a separate holding tank in which the solution is stored.

 

TREATMENT PROCEDURE

 

Generally:

To obtain best possible results during the treatment of process water it is recommended to collect rinse waters, half concentrates and concentrates in a separate collection tank.

 

Under normal conditions the pH will vary in this mixture of solutions.

The exact amount to be added and which pH-value to be used must be determined through trials in advance.

 

Batch treatment:

The pH value of the collected process water is first adjusted to pH 6,5 – 7,0 with sulphuric acid. Amount of SCANPOL® 15 needed for quantitative precipitation of heavy metals should be find by fields trials. Finally the pH is adjusted to optimum value with sodium hydroxide and flocculating agent SCANPOL® 55  is added. The clear decant can be separated and the sludge is dewatered in a filter press.

 

 

 

Through flow treatment:

 

SCANPOL® 15 is added in proportion to the flow to the pre neutralisation at the pH 6,5-7,0. Amount of SCANPOL® 15 needed for quantitative precipitation of heavy metals should be find by fields trials. Finally the pH is adjusted to optimum value with sodium hydroxide solution, flocculating agent SCANPOL® 55 is added and the sludge is separated in a lamella separator. The sludge is dewatered in a filter press.

Separate proposals for treatment plants and complete equipment for dosing are available upon request.
