Why Minimize (Waste = Cost + Risk)
• Reduce Waste Transporation
• Reduces cost (trucking ≈ $3 / m3 / hr)
• Reduces risk of release (environmental liability)
• Reduces risk of transporation accidents (safety)
• Reduce Waste Disposal
• Reduces cost (disposal facility gate fee ≈ $15 / m3)
• Reduces risk of production limits due to disposal availability
• Reduce Water Intake Requirements
• Reduces cost (sourcing and transporation)
• Reduces risk of production limits due to water availability
• Convert Waste to Value Products or Energy (emerging trend)

Confidential
• Forced circulation evaporator with a
specialized plate and frame heat
exchanger
• For NaCl based brines can operate with up
to 50wt% TS (Total Solids):
• 30wt% TDS (Dissolved Solids)
• 20wt% TSS (Suspended Solids)
• Coupled with dewatering equipment can
achieve up to 85wt% TS discharge.
