Generally best suited to sediments and clays, and to applications where water pH is acidic (< 6.5) and where the salinity is relatively high (> 500 conductivity).
It is generally the best option where chemical pretreatments such as Alum are applied prior to flocculant.
DamClear Self Dispersing (SD) Flocculants are a granulated version of the more common powder grade flocculants.
The granulation process incorporates a binder that enables the product to dissolve in water without the need for traditional prewetting devices that are otherwise required to prevent formation of insoluble gels. SD Flocculants are supplied at a controlled particle size of 1-3.5 mm
When dissolved in water DamClear SD Flocculants are used for water clarification on construction sites, in storm water retention dams, mine water dams, farm dams and for wastewater clarifiers. It is low cost, fast acting, environmentally safe & does not affect water pH or salinity. It contains no heavy metals, iron or aluminium.
DamClear SD is also used for soil erosion control on farms during flood irrigation and on constructions sites. DamClear reacts with sediment causing solids to settle rapidly leaving a clear treated water. Both anionic and cationic grades are available.
ADVANTAGES OVER POWDER FLOCCULANTS
• DUST FREE
User friendly product, no dust dispersed in plant area resulting in a safer work environment.
• SELF DISPERSING
No specialised wetting heads or venturi required to pre-wet the product. Just meter SD Flocculants directly into a mixing tank via a screw feeder. No lumps & “fish eyes” due to poorly wetted product.
• EASE OF USE
DamClear SD significantly improves materials handling, simplifies floc mixing system design & lowers capital cost & equipment complexity. Provides a very easy to use product for plant personnel.
• FREE FLOWING
No special vibrator required to assist product discharge from storage hoppers.
• LARGE PARTICLE SIZE
- In agricultural applications the larger particle size helps to retain product in flooded irrigation furrows.
- In drilling applications improves polymer penetration into deep bore holes.
- In water clarification applications, direct injection enables “multi-stage” type dosing, for improved performance and cost effectiveness.
