We considered the treatment of domestic wastewater by coagulation–adsorption–ultrafiltration, and a test of adsorption like pre-treatment to the membrane as an alternative for wastewater reclamation and reuse. The performances of two inorganic tubular membranes (M2 and M5 CARBOSEP with 15,000 Da and 10,000 Da MWCO) were studied. Powdered activated carbon was used as adsorbent agent and FeCl3 as a coagulant. Coupling adsorption and ultrafiltration resulted in satisfactory results: the efficiency of COD removal was increased by using PAC compared with results obtained when using only UF membranes.

The use of powdered activated carbon in combination with ultrafiltration membranes is attracting increasing interest for the removal of organic compounds in drinking water treatment. The overall adsorption efficiency of this hybrid membrane process strongly depends on the reactor configuration and its operating conditions. Identification of the operating conditions yielding optimum carbon performance can be facilitated by the use of mathematical models describing the adsorption process. In this study, the effect of various designs and operating parameters on the efficiency of the adsorption process is discussed using an adsorption model previously developed and verified by the authors. This discussion includes the effect of filtration time, membrane reactor volume, carbon dosing procedure, carbon dose and carbon particle size on the adsorption removal of two selected micropollutants and dissolved organic matter.

Photocatalytic is a developed technology in recent years for the wastewater treatment which is a new advanced oxidation technology. Stable, durable and highly active Nano-TiO2 is photocatalytic technology to be practical needs to solve, and also there are the important research hotspot.This paper adopts titanium sulfate and ammonia as raw material with nut shell activated carbon as a carrier was highly active load type, and activated TiO2 liquor X-3B simulation wastewater as the object of the degradation factors.

We evaluate the applicability of a reverse osmosis (RO) system that combines powdered activated carbon (PAC) and ultrafiltration (UF) to treat the effluent discharged from tannery wastewater treatment plants. Conventional treatment processes such as neutralization, clariflocculation, and biological processes are used to clean the effluent before feeding to the PAC and UF combined RO system. The efficiency of the combined system was evaluated using the chemical oxygen demand Mn (CODMn), color, pH, turbidity, total nitrogen, total phosphate, and conductivity. The PAC was effective in greatly reducing the CODMn and color. The turbidity and silt density index of the UF permeate satisfied the water quality indices required for the RO feed. The RO system was constantly maintained at approximately 75% RO recovery, and the RO permeate satisfied the water quality requirements for reusing the processed water. Therefore, the PAC-UF combined RO system can be used to process effluent discharged from tannery wastewater treatment plants for reuse.
