Wastewater Treatment

Wastewater treatment technologies can include clarification and/or filtration of suspended solids, pH neutralization of acidic or alkali waste streams, demineralization, and removal of hazardous organic contamination.

The requirements range from disposal allowance to reuse as plant process water to recovery of valuable products in the contaminated stream.

A.H. Lundberg offers process engineering, system design & supply, and plant integration of various technologies to meet these needs.

A.H. Lundberg -Stripping Column

An effective method of treating process foul condensates (sour water) contaminated with hazardous hydrocarbons, sulfides, ammonia, methanol, and TRS is the distillation of the waste water stream through steam stripping.
Every A. H. Lundberg stripping system contains the same basic components including a feed tank, filter, condensate pre-heater, stripper column with rectification section and a reflux condenser.

DBE- Nanoflotation-Pilot-Plant

A.H. Lundberg and David Bromley Engineering are consortium partners working together to commercialize a unique technology called Nanoflotation.

Nanoflotation uses concentrated ionically charged nano environments to cause repulsion of colloidal solids followed by attachment of solids. The repulsion and attachment processes result in a rapid, low energy method to separate colloidal solids from fluids.

A.H. Lundberg-Electrocoagulation integration with Evaporator

A.H. Lundberg is partnering with electrocoagulation vendors to solve the challenges faced by the oil & gas industry in treating wastewater.

Electrocoagulation can efficiently remove contaminants such as suspended oil and grease, silica, calcium, magnesium, heavy metals and suspended solids from aqueous waste streams. A primary advantage of the process is high removal efficiency (90%-99%) of the contaminants with no chemical addition, minimum waste produced, low power operating cost (4-7 kWh/1000 gals treated) and minimal manpower requirements.

Feed from the electrocoagulation process is transferred to the evaporation process.  A simple block diagram shows how the Zero Liquid Discharge process can be designed.
