Waste liquid / Sludge

J&T Recycling detoxifies various waste liquid and sludge with an environment friendly treatment system.

Overview of waste liquid recycling

Chemical plant

Our company's highly concentrated waste liquid system can treat a variety of waste liquids, sludge, and ammonia water. The treatment system with the lowest environmental load is selected for each type of liquid to be detoxified. J&T Recycling also actively recycles dehydrated cakes, etc. after waste liquid treatment and effectively utilizes recovered ammonia.

Configuration of waste liquid recycling system

  1. 1.Neutralization/insolubilization process

    Waste acid, waste alkali, sludge, etc. containing waste acid and waste alkali of highly concentrated waste liquid (Zn, Fe, F, etc.) and hazardous substances (Hg, Cd, Pb, Cr6+, As) are detoxified safely by technically advanced processes.

  2. 2.Biological treatment

    Measures against COD and nitrogen have advanced widely by adopting an aerobic / anaerobic biotreatment process that decomposes nitric acid waste liquid as nitrogen via a technologically advanced eco-friendly technique. The process serves as a reasonable and stable treatment when treatment volumes increase.
  3. 3.Recovery of ammonia

    The ammonia (NH3) contained in waste liquid is recovered. The recovered ammonia water is reused externally.
