Separating Agent; Operating Regulations - Storch Color Free Basic Mode D'emploi

9. Separating agent

9.1. Emulsion separation principle
2. Admixing the separating agent
3. Separation process
4. Sludge/water separation
STORCH separating agent is specially designed for cle-
aning decorating wastewater and is easy to handle and
use.
After intensive admixing with the wastewater, the sepa-
rating agent causes the pollutants to separate and floc-
culate, thus allowing them to be filtered out as residues.
9.2. Checking the filtrate
(treated wastewater, see illustration)
Following optimum separation, the water phase is clear, i.e., there is no cloudiness. The sludge should comprise suf-
ficiently large flakes of 25 mm. If the treated wastewater continues to be cloudy despite a large dose of separating
agent, first check the pH value of the wastewater (see item 11.). If the pH value of the wastewater does not reveal any
reasons, check if lyes, detergents or similar have been fed into the system (see item 10.2.).
WARNING:
Solvents do not cause cloudiness and can thus be dissolved in the wastewater despite a clear filtrate.
The required separating agent volume for optimum treatment depends on the degree of soiling of the
wastewater, i.e. on the paint and solid matter concentration.

10. Operating regulations

The decorating wastewater to be treated in the separating system must fulfil certain conditions to ensure functionally
reliable operation, and comply with mandatory limits. In particular, you must check the pH value of the wastewater
(see item 11.2.).
10.1. Separating system applications
‒ Flushing water/washing water: cleaning of brushes, rollers, containers and equipment soiled with water-soluble
paints (paint component max. 1 %).
‒ Wastewater from wet sanding/roughing
‒ Wastewater from leaching (volume restrictions apply, check the pH value).
‒
10.2. Wastewaters and materials that must not be fed into the separating system
‒ Chlorinated solvents: (e.g. from stripping pastes/brush cleaners)
‒ Wastewater from stripping work with chlorinated solvents
‒ Wastewater with a high ammonium chloride content
‒ Wastewater from leaching
‒ Paint and lacquer residues containing solvent (such as, synthetic resin , nitro, containing terpentine, or similar)
‒ Thinners/solvents
‒ Brush cleaners (including „biologically degradable": high concentration of aromatic hydrocarbons)
‒ Acids and brines (see item 11.)
‒ Soapy water
