HEI custom designs the systems, manufactures the equipment including handrails and catwalks, installs the equipment and commissions the process. Systems have been installed varying in sizes from batch treatment plants treating 2,000 gallons per week to large integrated systems processing 3,000 gpm, totaling 4,000,000 gallons per day.

HEI contracts for the entire turn-key project to include earthwork, concrete, foundation, tanks and buildings.

Hoffland Environmental also designs and fabricates its own electrical control systems. The custom equipment varies in complexity from a simple control relay logic panel to PLC to SCADA control with remote programming and monitoring on a modem from HEI’s engineering office in Conroe, Texas.

HEI is bondable by treasury rated surety.

HEI installed a 2,000 gpm integrated turn-key plant in 1991. This plant included:

  • Screen Separation
  • Grit Separation
  • Oil Water Separation
  • Equalization and Storage
  • Dissolved Air Flotation
  • VOC Air Stripping
  • VOC Carbon Adsorption
  • Chromate Reduction
  • Physical Chemical Separation
  • Clarification
  • Filtration
  • Carbon Adsorption
  • Membrane Separation Recovery and Reuse
  • Sludge Compaction
  • Sludge Drying

The entire process is monitored and controlled from one central SCADA control.

A detail of the process plus P&I diagrams are included under Sample Integrated Systems.

P&I diagrams are also provided for specific processes utilized by the “textile wastewater treatment” industry.

Hoffland Environmental manufactures its own inclined plate clarifiers, filter presses, dissolved air flotation systems, sludge thickeners, sludge dryers, continuous polymer make-up and activation units, automatic sand filters, oil water separators and compact package treatment plants. HEI maintains a complete integrated fabrication and assembly plant in Conroe, Texas. All steel equipment is sand blasted and coated with ultraviolet resistant epoxy paint.
