Nanofiltration Equipment

The volume of the cell was 189 mL, the inner diameter 56.6 mm (resulting in a membrane surface area of 21.2 10 m. The stirrer speed could be varied from about 200 to 2000 rpm, with a setting of 400 rpm used routinely. The stirrer speed was measured using a Philips PR 9115/00 stroboscope. One side of the stirrer bar was labelled to avoid measuring of half rotations. [Pg.97]

The cell was equipped with a pressure gauge mounted in the stainless steel line after the air cylinder, a stainless steel reservoir with a volume of 2 L, a pressure release valve, a fluid inlet and oudet connection, a pressure safetj- valve, and a refill opening on top of the reservoir. On top of the stirred cell, a fluid inlet connection, a pressure release valve and a temperature probe fitting were mounted. The temperature was measured with a PT 100 probe, connected to a Kane-May KM 330 indicator. [Pg.98]

To control the temperature inside the cell, it was placed in a 2 L plastic beaker, through which tap water was circulated continuously. The temperature was kept constant (unless otherwise indicated) at 20 C 1 C. Permeate flux was measured by weight with a Metder-Toledo PR 2002 (0.1 to 2100g) balance, which was connected to a PC equipped with Mettler-Toledo BalanceLink software. [Pg.98]

A Beckman glass electrode (Ag/AgCl) was used for soludon preparations and no contamination was observed. The electrode was only used in samples after DOC analysis and was cleaned prior to use for pH adjustment. [Pg.98]


The new Kvaerner Chemetics process is low in both capital and operating costs and the effluent purge is significantly reduced. The process is based on a technique known as nanofiltration and the equipment is normally installed in a dechlorinated brine-side stream (see Fig. 11.1). [Pg.154]

Researchers at Degussa AG focused on an alternative means towards commercial application of the Julia-Colonna epoxidation [41]. Successful development was based on design of a continuous process in a chemzyme membrane reactor (CMR reactor). In this the epoxide and unconverted chalcone and oxidation reagent pass through the membrane whereas the polymer-enlarged organocatalyst is retained in the reactor by means of a nanofiltration membrane. The equipment used for this type of continuous epoxidation reaction is shown in Scheme 14.5 [41]. The chemzyme membrane reactor is based on the same continuous process concept as the efficient enzyme membrane reactor, which is already used for enzymatic a-amino acid resolution on an industrial scale at a production level of hundreds of tons per year [42]. [Pg.400]

The pincer-based carbosilane dendrimers Go-2 and Gi-2 were tested for their degree of retention in a membrane reactor equipped with a SelRO-MPF-50 nanofiltration membrane [35,36]. Their retentions were measured... [Pg.12]

The removal of MTBE by membrane micro- or ultrafiltration is highly ineffective due to the molecule s small size. Only nanofiltration showed removal potential. However, the process is very elaborate and expensive in terms of equipment and operating conditions (low transmembrane flux, high membrane area). Moreover, the resulting water needs further treatment in order to comply with drinking water standards, and the concentrate has to be treated before discharged. [Pg.326]

Nanofiltration experiments were carried out in a stainless steel stirred cell with an Amicon magnetic stirrer on a magnetic heater plate (Industrial Equipment Control, Australia). The calibration is shown in Figure 4.2. [Pg.97]

Rigs were conneeted to the laboratory water supply (after water treatment by nanofiltration, at TZW). The test deviee ineluded equipment (valves, solenoid valves plus programming system, flow meter, sampling valves, etc.) for the adjustment and control of flow regime and for water sampling (Figure 4.4). [Pg.132]

With the soluble polymer-supported catalyst 57 (Scheme 27), the reduetion of acetophenone was performed in a continuous operated membrane reactor equipped with a nanofiltration membrane [54], An enhancement of total TON from 10 to 560 (equivalent to 0.18 mol % catalyst for an average ee of 91% and an almost quantitative conversion) was observed. Excellent space-time yields of up to 1.4 kg per day were reached... [Pg.65]

Research projects in sanitary engineering include seeking processes and equipment for improved purification efficiency. One example is the development of large, portable water-treatment systems that are suitable for providing clean water to survivors of natural disasters and the bivouac medical units that treat them. Another example is a nanofiltration system that desalinates ocean water for use on naval ships, especially during times of conflict, and extended private offshore operations such as oil drilling. A related nanofiltration system is necessary for oil-spill cleanup. A third example is the specialized absorbent removal of microcontaminants that may be present in small yet detrimental amounts. These may include elements such as arsenic and lead, industrial solvents, and radioactive particles. [Pg.1639]

In the frame of integrated approach to the nanofiltration, an extensive characterisation of membranes is essential for adequate choice of membrane. The results of multi-annual fundamental research enabled to define and design new equipment for membrane characterization. [Pg.679]
