Hoffland Environmental, Inc. (HEI) is a premier name among wastewater treatment equipment manufacturers, serving as a registered Professional Engineering (PE) firm since 1978. Based in Conroe, Texas, HEI functions as a dedicated Original Equipment Manufacturer (OEM) for critical environmental infrastructure. Our specialized portfolio includes Inclined Plate Clarifiers, Oil/Water Separators, and Dissolved Air Flotation (DAF) units, all engineered with total process responsibility validated by over 1,000 global installations.
Core Wastewater Treatment Equipment Manufactured by HEI
HEI designs and fabricates custom industrial wastewater treatment systems engineered for high-efficiency contaminant removal, regulatory compliance, and long-term operational durability. Each system is built based on wastewater characteristics, flow rate, discharge requirements, and site constraints.
Below is a breakdown of HEI’s primary manufactured equipment categories and what each system does:
Industrial wastewater characteristics vary significantly across industries and processes. Off-the-shelf systems frequently lead to underperformance, permit violations, excessive sludge production, and increased operating costs. HEI’s engineering-first OEM approach ensures that every system is designed based on wastewater characterization, flow rate, contaminant profile, and regulatory discharge limits.
As a registered PE firm, HEI maintains full engineering oversight and fabrication control, reducing risk while delivering durable, application-specific wastewater treatment infrastructure.
An industrial wastewater treatment equipment manufacturer designs and fabricates systems that remove solids, oils, chemicals, and dissolved contaminants from industrial process water before discharge or reuse.
A clarifier removes suspended solids through gravity settling, while a DAF system uses air flotation to remove lighter particles, fats, oils, and grease.
Reverse osmosis is used when dissolved solids must be significantly reduced to meet strict discharge standards or support water reuse initiatives.
Proper sludge thickening, dewatering, and drying reduce disposal costs, improve plant efficiency, and support regulatory compliance.
Custom OEM manufacturers engineer systems based on specific wastewater characteristics and compliance requirements, ensuring higher performance, reliability, and long-term cost efficiency compared to generic solutions.
