Penberthy Model 62DP Flocculant Disperser

Penberthy Model 62DP Flocculant Disperser is used when powder must be combined with water to create the perfect mix of chemical concentrations. Dispersers can effectively wet 2.27 kg (5 lb) of powder for every 37.8 to 56.7 L (10 to 15 gal.) of water supplied to the unit, resulting in a 4 to 6% concentration of flocculant in the water. This mixture must then be mixed thoroughly with additional water until the powder is dissolved completely and the desired solution concentration obtained. Water supply pressures from 20 to 100 psig (1.37 to 6.89 barg) can be used. Purchase the Penberthy Model 62DP

The Penberthy Model 62DP Flocculant Disperser is a ‘small job’ device and operates in a similar manner to a ring jet; the nozzle having the same basic characteristics.

SPECIFICATIONS

The Penberthy Model 62DP Flocculant Disperser & funnel are made from DELRIN®.  DELRIN® is a crystalline plastic which offers an excellent balance of properties that bridge the gap between metals and plastics. DELRIN® possesses high tensile strength, creep resistance and toughness. It also exhibits low moisture absorption. It is chemically resistant to hydrocarbons, solvents and neutral chemicals. These properties along with its fatigue endurance make DELRIN® ideal for many industrial applications.

DELRIN® construction offers:

• Good dimensional stability
• Low moisture absorption
• DELRIN® can operate in wet environments with little effect on performance or dimensions.
• Excellent machinability
• High fatigue endurance
• High strength and stiffness properties
• Superior impact and creep resistance
• Chemical resistance to fuels and solvents
• Natural grade is FDA, NSF and USDA compliant
• Good wear and abrasion properties with its low coefficient of friction and hard and resilient surface it is the material of choice in many wear applications.

TYPICAL APPLICATIONS
Once considered a flocculant disperser for use primarily in wastewater treatment applications, the 62DP could be used for any dry powder or granular product.

Flocculants, or flocculating agents (also known as flocking agents), are chemicals that promote flocculation by causing colloids and other suspended particles in liquids to aggregate, forming a floc. Flocculants are used in water treatment processes to improve the sedimentation or filterability of small particles. For example, a flocculant may be used in swimming pool or drinking water filtration to aid removal of microscopic particles which would otherwise cause the water to be turbid (cloudy) and which would be difficult or impossible to remove by filtration alone.

Many flocculants are multivalent cations such as aluminium, iron, calcium or magnesium. These positively charged molecules interact with negatively charged particles and molecules to reduce the barriers to aggregation. In addition, many of these chemicals, under appropriate pH and other conditions such as temperature and salinity, react with water to form insoluble hydroxides which, upon precipitating, link together to form long chains or meshes, physically trapping small particles into the larger floc.

Long-chain polymer flocculants, such as modified polyacrylamides, are manufactured and sold by the flocculant producing business. These can be supplied in dry or liquid form for use in the flocculation process. The most common liquid polyacrylamide is supplied as an emulsion with 10-40% actives and the rest is a non-aqueous carrier fluid, surfactants and latex. This form allows easy handling of viscous polymers at high concentrations. These emulsion polymers require “activation” – inversion of the emulsion so that the polymers molecules form an aqueous solution.
