Engineering the Future of Biosolids Management

Real problems. Real systems. Real-world impact.

At Merrell Bros., Inc., engineering isn’t theoretical. It’s applied, tested, and built to perform in the field. Our team designs and delivers patented biosolids technologies that reduce costs, improve sustainability, and create long-term solutions for municipalities and industries across the country.

From concept to commissioning, our engineers turn complex challenges into working infrastructure.

Engineering Solutions for a Growing Infrastructure Challenge

Across the country, wastewater facilities are facing increasing pressure:

  • Rising disposal and transportation costs
  • Tightening environmental regulations
  • Aging infrastructure
  • Limited long-term solutions

Our engineering team works together to solve these problems, not in theory, but through deployable, scalable systems that work in the real world.

From concept to commissioning, our engineers turn complex challenges into working infrastructure.

Our Technologies, Engineered In-House

Our patented technologies are developed by our internal R&D and engineering teams and deployed across real-world facilities. Each system is designed to solve a specific challenge in biosolids management.

Solar-Thermal Pasteurization uses enclosed greenhouse drying and a specialized oven system to dry out biosolids, significantly reducing transportation costs while creating a safe, Class A fertilizer product.

Pelletization turns biosolids into clean, uniform fertilizer pellets for efficient storage and distribution. Our pelletization system connects to any wastewater plant with existing dewatering capabilities.

Double Drum Drying uses steam-heated rotating drums and a specialized oven system to dry out biosolids, significantly reducing transportation costs while creating a safe, Class A fertilizer product.

Reverse Osmosis uses high-pressure membrane filtration to remove contaminants and recover clean water, reducing waste and improving overall system efficiency while supporting sustainable operations.

Built by Engineers Who Solve Real Problems

Our engineers are directly involved in designing, building, testing, and improving the systems we create and deploy internally at Merrell Bros..

Here, you don’t just design, you see your work operating in the field.

  • Work moves from concept to real-world implementation
  • Direct collaboration across teams
  • Exposure to full lifecycle engineering
  • Opportunity to influence patented technology development

A Culture Built on Ownership and Impact

We believe engineers do their best work when they:

  • See the impact of what they build
  • Take ownership of real outcomes
  • Work alongside people who execute

At Merrell Bros., engineers are trusted to solve problems, not just complete tasks.

What It’s Like to Work at Merrell Bros.

  • Hands-on engineering environment
  • Fast path from idea to implementation
  • Cross-functional collaboration
  • Real accountability and real results
  • Work that directly impacts communities and infrastructure
