Drewfloc™ flocculants

Chemically treating influent water that is used in industrial processes ensures a consistent and reliable supply of water that meets required quality standards. Likewise, the proper treatment of wastewater ensures that the water is suitable for discharge to natural waterways. The type of treatment employed depends on the water source, its chemical content and its intended use.

Ashland’s Drewfloc flocculants comprise a family of proprietary products, including anionic, cationic and nonionic emulsions and dry polyacrylamides, which can be used whenever liquid/solids separation is required in industrial and municipal applications.

Description
Benefits
Chemical Processing
Influent Treatment

Drewfloc flocculants are effective settling aids that can be used alone or in conjunction with coagulants to clarify influent water or wastewater. Commercial applications confirm this and typically result in a number of value-added benefits.

● Improved settling and separation
● Improved floc size and formation
● Minimizes sludge

Wastewater Treatment

Drewfloc flocculants are the products of choice for wastewater applications such as thickening and sludge dewatering. Commercial applications confirm this and typically result in a number of value-added benefits.

● Improved drainage
● Improved cake dryness
● Improved filtrate quality
● Improved throughput

Partnership with TenCateHow this product is used with with Geotube containers

TenCate Geotube Technology

Ashland and TenCate, the leading manufacturer of geosynthetic materials, have worked in partnership since January 2010 to provide low-cost, high-volume dewatering solutions for a diverse mix of customers.

TenCate’s specially engineered Geotube* containers work in conjunction with Ashland’s Amerfloc™, Chargepac™, Drewfloc™ and Praestol™  coagulants and flocculants to provide exceptional containment and dewatering of sludge and sediment. Key applications include marine remediation; pulp and papermaking; mining and mineral processing; hydrocarbon and chemical processing; food and beverage processing; power generation, and municipal water and wastewater treatment.

When used together in commercial applications, TenCate Geotube technology and Ashland’s coagulants and flocculants have been shown to provide a number of value-added benefits, including:

● Improved sludge dewatering
● Improved liquid-solid separation
● Increased retention of contaminants (solids, BOD, metals)
● Reduced downtime
● Reduced costs
