INTRODUCTION OF PAINT DETACKIFICATION
What is Paint Detackification? A Program that be used to treat paint overspray from
water circulation for painting booth.
A Detackification program should have the capability to provide:
Good detackified sludge
Less order from the water
High sludge removal efficiency
Clean recirculating booth water
High sludge solids and low sludge volume
Low corrosion rate
Better foam control (less emission)
Microbial control (safety)
-
The typical Paint Detackification Program consists of 5 chemical products that each serves a specific function:
Detackifier D2430S
Reduce or eliminate paint tackiness
Coagulation of paint solids
Flocculant - D2402
Agglomerate suspended paint solids
Enhance paint sludge removal from the process
Improve dewatering of sludge
pH adjuster
Ensure water is in condition to properly detackify paint solids
Minimize corrosion rate
Additive
Oxidize the solvents to eliminate smell
Biocide
Control bacteria levels
Minimize corrosion
Without Treatment Detackification Flocculation

PARAMETERS OF SLUDGE PAINT TREATMENT SYSTEM
-
Cutomer Goals
Automotive manufacturers are looking for products with improved performance while seeking to reduce overall system cost Lower suspended solids returning back to spray booths Simplify the paint spray booth process to reduce capital investment Reduce energy and cleaning costs
Auto industry as a whole is striving for more environmentally responsible solutions Conserve non-renewable resources Minimize carbon footprint Reduce waste Non smell spread
OEMs desire less complexity in the manufacturing process Ease of operation Process flexibility
Vision & Goals

Vision & Goals
Customer Benefits
Positive environmental impact Reduce carbon foot print from other chemical contribution Reduced daily wastewater treatment impact Conservation of water Decreased land fill volume
Superior product performance Improved sludge removal efficiency Reduced sludge settling Fewer paint solids returned to paint spray booths Cleaner booth water Decreased foam formation (due to bio-adhesive properties) Lower total dissolved solids and corrosion tendency Longer booth water life
Greater ease of operation and process flexibility Wider operating window (less pH sensitive, less foam formation) Decreased paint spray booth maintenance (lower suspended solids) Effective treatment vs. solvent borne/waterborne. Proven pour over transition
Lower overall system costs Reduced paint spray booth maintenance, chemical, wastewater treatment, and
disposal costs
-
Experience with all sludge system designs
Not only with good chemical programs, but knowing how in
application is the turn key for success
Capability to assist and/or advise for the design of the most efficient system
to:
Lower the chemical cost
Minimize labor intensity
Maximize system performance
VALUE PROPOSITION - SYSTEM DESIGN
