Explore SpecificationsThe greater Boston metropolitan area—from the research epicenters of Cambridge to the industrial corridors of Route 128 and the South Shore—is home to one of the world's most dense concentrations of biopharmaceutical manufacturing, chemical synthesis facilities, and high-tech manufacturing plants. Operating in this region requires compliance with the stringent environmental standards set by the Massachusetts Department of Environmental Protection (MassDEP) and the Massachusetts Water Resources Authority (MWRA).
For local industries, raw wastewater discharge is no longer viable due to steep surcharges on high chemical oxygen demand (COD), total suspended solids (TSS), and dissolved mineral streams. This regulatory climate has accelerated the adoption of industrial thermal separation technology. By utilizing custom-engineered falling film and forced circulation evaporation systems, chemical and biological processors can concentrate high-salinity wastes, recover valuable solvents, and achieve zero liquid discharge (ZLD) metrics.
Whether you are scaling up a pilot plant in East Cambridge or upgrading a chemical process line in Worcester, our engineering team supplies process equipment designed to lower municipal sewer fees, minimize water intake, and decrease operating expenditures (OPEX).
Selecting the appropriate evaporator configuration requires evaluating liquid characteristics, fouling tendencies, local utility rates, and thermal sensitivities.
Ideal for: High-efficiency, continuous setups seeking low energy footprints.
MVR plants act as open-loop heat pumps. Overhead vapor is mechanically compressed to a higher pressure and temperature, then returned as the heating medium. This eliminates the need for prime boiler steam during normal operation.
Ideal for: Heat-sensitive products, biological enzymes, and low-viscosity applications.
The process fluid is distributed uniformly into the inner tubes, flowing downwards as a thin, boiling film. Due to the high heat transfer coefficient and brief residence times, thermal degradation of active ingredients is avoided.
Ideal for: High fouling feeds, crystallizing solutions, and industrial wastewater solids.
High recirculating pumps maintain turbulent velocity through the heat exchanger tubes. Boiling is suppressed until the fluid enters the flash vessel, preventing crystallization and scale formation on heat exchange surfaces.
