What Is an MVR Evaporator? 2026 Working Principle, Specs & Cost Guide
An MVR evaporator recompresses secondary vapor and reuses it as heat, cutting live-steam demand to about 0–0.1 ton per ton of water after start-up. Typical compressor power is 10–30 kWh per ton at 50–90°C boiling duty under 0.2–0.5 bar absolute. Specs, CAPEX ranges, pretreatment triggers, and MVR–TVR–MEE selection rules are summarized for wastewater and ZLD projects.
What Is IFAS Wastewater Treatment? 2026 Process & Design Guide
IFAS (Integrated Fixed-film Activated Sludge) suspends HDPE biofilm carriers inside a conventional activated-sludge aeration tank, running attached and suspended biomass together. Typical designs use 30–50% carrier fill, 4–8 h municipal HRT, and deliver 85–95% BOD removal with 90–98% ammonia-nitrogen removal. Choose IFAS for CAS nitrification retrofits and cold-weather ammonia limits; choose MBR when reuse turbidity below 1 NTU is required.

Design covers generation energy, mass transfer, AOP pathway choice, contactor sizing, and off-gas destruction under OSHA 0.1 ppm PEL.
IFAS Working Principle: 2026 Industrial Wastewater Retrofit
This article explains the IFAS working principle for industrial wastewater retrofit projects: biofilm carriers added to an existing aeration tank hold nitrifiers at an effective SRT of 20–40+ days while suspended MLSS at 2,500–4,000 mg/L removes BOD. It compares IFAS with MBBR, MBR, and conventional activated sludge on HRT, effluent ammonia, CAPEX, and OPEX. Typical 2026 retrofit costs run $250–$650 per m³ of upgraded aeration volume, with energy up 5–15% and sludge handling down 20–30%.
