Water and Wastewater

Proven defense

Fiber-reinforced plastic (FRP) made with Ashland Derakane™ and Hetron™ epoxy vinyl ester resins is heavily used in water and wastewater service. It is particularly well-suited to seawater piping in cooling water systems and desalination plants. Design engineers rely heavily on these resins for the fabrication of sodium hypochlorite (bleach) storage tanks and piping systems.

Scrubbers, Ducting, Stakes and Fume Handling Equipment
Derakane™ resins offer a variety of benefits making them ideal for all types of corrosive fume handling equipment.  They are tough when it comes to providing thermal insulation and electrical insulation along with abrasion resistance and flexibility for use in a wide variety of environments. Derakane stands up to corrosive process streams, scrubbing chemical fluids and chemical by-products of scrubbing processes and cleaning solutions.

Tanks
Due to their resistance to corrosion, Derakane™ resins provide an economical solution by eliminating the need for linings in both the mixing and neutralization storage tanks and processing vessels.

FRP tanks using Derakane resins provide:

  • corrosion resistance in virtually all chemically intensive environments
  • cost efficient maintenance
  • easy installation (lightweight)
  • low thermal conductivity properties - little to no insulation necessary
  • no electrolyte attack (cathodic protection not required.)

Highly corrosive sodium hypochlorite solutions create a unique challenge for water treatment facilities.  FRP made with Derakane resin is rapidly replacing costly and hard-to-find titanium and cost effective but low-performing polyethene in bulk storage tanks and piping in water processing plants.

Pipe
Ideal for use in both above and below ground piping, lightweight Derakane™ resins offer both performance and cost effectiveness.  With lighter weight Derakane pipes, lower cost pipe hangers and bridges can be used.

Benefits of composite pipes made with Derakane resins include:

  • corrosion resistance to a wide range of chemicals
  • abrasion resistance
  • lightweight, lower cost installation
  • assembly without arc welding
  • low thermal conductivity

Gratings, Ladders & Railings
With multiple benefits, composites manufactured with Derakane™ are an ideal replacement for more maintenance-intensive metal structures. The need to paint, is eliminated since the color is molded in during the fabrication process, thereby saving time and money.  In addition to their cost effectiveness, Derakane resins provide corrosion resistance, offer electrical insulation properties and have high strength-to-weight ratios.  Pultrusion fabrication techniques provide maximum strength properties at economical levels.

Protective Linings and Floorings
Tank life can be extended, saving both time and money, when Derakane resins are used to formulate corrosion resistant tank coatings and linings.  Derakane resins can be used on the exterior & interior of both new and existing tanks and provide:

  • extended service life over metal equipment
  • the advantages of nonolithic flooring versus concrete
  • lower maintenance costs
  • containment of spills
