Catalyst Recovery by Membrane Separation | Solid-Liquid Separation Solution for Fine Chemicals
Membrane separation technology for catalyst recovery achieves high-efficiency solid-liquid separation of ultrafine catalysts. It retains precious metal catalysts, obtains clear filtrate, cuts costs and reduces hazardous waste for fine chemical and pharmaceutical intermediate production.
Membrane Technology for Lemon Juice: Clarification, Cold‑Concentration & Cold Sterilization
Traditional lemon juice processing often depends on thermal evaporation and diatomaceous‑earth filtration, which risk losing fresh aroma, destroying vitamin C and creating cooked off‑flavors. Cross‑flow membrane separation (MF, UF and nanofiltration NF) delivers cold clarification, ambient‑temperature concentration and cold sterilization for lemon juice. Operating under room‑temperature conditions, membrane systems remove pulp residues, pectin, colloids and microorganisms while preserving citric acid, natural aroma compounds and heat‑sensitive nutrients. It helps beverage producers obtain stable clear lemon juice concentrate, cut logistics costs and improve final product quality.
Oilfield Produced Water Treatment by Membrane Separation Technology
Oilfield produced water contains crude oil, suspended solids and organic pollutants, posing challenges for discharge and reuse. Doupu’s membrane separation technology effectively removes oil contaminants. The lab test shows stark visual contrast: raw oily wastewater is turbid brown, while the permeate after membrane filtration becomes clear, and oil plus impurities are concentrated in retentate. This membrane solution enables water recycling for oil & gas plants, cuts operational costs and reduces environmental risks.
