Polyaluminum Chloride (PAC) | GEO Specialty Chemicals
The lowest basicity commercial PAC's are about 10%; most PAC's are in the medium to high basicity range (50-70%). At the top of the scale is aluminum chlorhydrate (ACH): at 83%, it is the highest stable basicity PAC available. (ACH is simply a special species of PAC - more about ACH in the next section).

Microplastics in drinking water treatment – Current
To the best of our knowledge, raw water directly from the inlet of DWTPs has only been investigated by two studies (Pivokonsky et al., 2025; Mintenig et al., 2025), one of which dealt with surface water and the other with groundwater.By comparison, there are many more studies on MPs in freshwater bodies, but the research on MPs in groundwater is lacking.
Water as a resource. Water resources refer to the freshwater available for use in a territory and include surface waters (lakes, rivers and streams) and groundwater.Renewable water resources are calculated as the sum of internal flow (which is precipitation minus actual evapotranspiration) and external inflow.Freshwater availability in a country is primarily determined by climate conditions

- Are NT & ml pursuing a patent for fiber-based water treatment?
- N.T. and M.L. have applied for U.S. provisional patents on the use of fiber-based materials for water treatment. H.J. and J.M.F. declare no competing interests. Publisher’s note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.
- How sustainable are fiber-based materials compared to conventional physicochemical treatment?
- These sustainable fiber-based materials considerably increased the floc size (~6,630 µm) compared to conventional physicochemical treatment using a coagulant and a flocculant (~520 µm). The materials also reduced coagulant usage (up to 40%) and flocculant usage (up to 60%).
- Can surface modification improve fouling resistance of UF membranes?
- A number of studies have reported the successful preparation of fouling-resistant membranes by various methods. Surface modification has been considered as one of the most effective strategies to improve the fouling resistance of the UF membrane.
- Which water treatment plant uses HFW 1000 membranes?
- The HFW 1000 membranes from Pentair X-Flow are applied in a full-scale membrane system on surface water in Tasmania, Australia. The water treatment plant provides 60 m 3 ·h −1 of potable water in a chemical-free one-step process [ 47 ].
