Filter press case studies and application notes across nine industries: mining, chemical, food & beverage, pharmaceutical, power & new energy, metallurgy, stone, municipal wastewater, and oil & gas.
SBR for variable loads and greenfield sites, MBBR for upgrading an existing tank, MBR for reuse and tight discharge limits. A side-by-side comparison with EPA figures, plus what each process means for sludge dewatering.
Quick answer: Use DAF when the solids float rather than settle — oil, grease, fats, fibres and light flocculated solids. If your solids settle readily, a clarifier does the same job for less money and less maintenance. DAF almost always…
Quick answer: Biological nitrification-denitrification is the default and the cheapest at normal concentrations. Above roughly 500 mg/L, air stripping or struvite precipitation usually comes first to knock the load down. Ammonia is the parameter most often missed in winter, because…
Quick answer: First establish whether your COD is particulate or soluble, because the answer decides everything. Particulate COD comes out cheaply with coagulation and settling or flotation. Soluble COD needs biological treatment, and only the stubborn remainder needs advanced oxidation…
Yes. A chamber or membrane filter press can dewater oily sludge and drilling mud to 30 to 45% cake moisture when free oil is kept below about 10 to 15% of solids, the slurry is heated to 50 to 70 °C or demulsified, and monofilament or PTFE-coated cloth is used. Cycle times run 1.5 to 4 hours.
A chamber filter press dewaters marble, granite and engineered stone cutting slurry from 10 to 30% solids to a 20 to 28% moisture cake in 20 to 40 minute cycles and returns 90 to 95% of the water to the saws. Most cutting shops use 800 to 1250 mm plates, abrasion-resistant monofilament cloth, and automatic plate shifting for unattended operation.
