Scale is the leading cause of lost capacity in wastewater evaporators. This guide explains the salts that deposit on hot surfaces, the design choices that prevent scaling, and how to clean it.
Boiling point elevation is the hidden temperature gap that drives compressor duty, heat exchanger area, and achievable concentration in MVR evaporators. This article explains how BPE works in the loop, how to estimate it for real wastewater, and where it forces design trade-offs.
Sizing an industrial wastewater evaporator starts with the true hourly evaporation rate, not average flow. This guide walks through mass balance, stream characterization, technology selection, heat exchanger and compressor duty, concentration limits, and material choice.
Evaporator condensate is rarely clean water: it carries measurable COD, ammonia and volatile organics depending on feed chemistry, temperature and de-entrainment design. This article explains where carryover comes from, how to predict it, and how to design around it.
A practical guide to choosing between 316L, duplex 2205, and titanium Grade 2 for evaporator wetted parts, based on chloride concentration, pH, temperature, and cleaning chemistry.
RO concentrate treatment is a sequence decision, not a single-technology choice. This guide compares membranes, evaporation and crystallization, and shows how to combine them based on brine volume, chemistry and discharge limits.
A practical guide to high-TDS industrial brine treatment, covering membrane preconcentration, MVC/MVR and multi-effect evaporation, zero liquid discharge, and the pretreatment that determines whether a system runs reliably for years.
A practical guide to selecting high-TDS wastewater treatment technology, comparing membranes, evaporation, and ZLD on performance, cost, and maintenance trade-offs.
A practical guide to MVR evaporator troubleshooting, covering how to recognize and fix scaling, foaming, carryover, and compressor problems before the unit trips offline.
A practical walkthrough of the zero liquid discharge train: how RO, MVR evaporation, and crystallization work together, and where scaling, fouling, and brine chemistry decide whether the system runs smoothly.
