1. Introduction. With the increasingly growing world population, water crisis has become one of the grand challenges in the 21st century .To date, reverse osmosis (RO) is the key technology for desalting water to alleviate the water scarcity .Membrane is one of the most critical components in an RO desalination plant, and it largely determines the separation performance of the overall plant .

The present work investigated the permeation behavior at high pressure of four commercial grade media used for natural gas filtration. Samples of nonwoven fabrics (cellulose, polypropylene and

Activated sludge dewatering is of great importance in sludge treatment and disposal. To enhance the dewaterability, a novel method was performed by treating the sludge under mild temperature (50

To measure the thickness of a product layer, the probe is lowered into the well until the signals activate. If there is an oil/product layer on top of the water (LNAPL), a specific signal is made by the instrument, indicating an air/product interface. The depth is read off the permanently marked tape.

Hydrogen sulfide is sometimes present with iron and/or manganese. It will then cause black sticky precipitate which stains everything. Removal can be accomplished with a manganese greensand filter (up to 2 ppm H2S) or chlorination using a chemical pump, retention tank, and followed by an activated carbon filter.

Among different technologies related to production, separation and purification of H 2, membrane technologies really seem to play a fundamental role.In particular, owing to its attractive capability of continuous operation and process miniaturization, membrane separation, an energy saving technique without any phase transformation, can be considered a good candidate for replacing conventional

Layer FiltrationGranular media. Several materials have been used as granular media; these include sand, crushed anthracite coal, perlite, diato maceous earth, garnet or ilmenite sand, and powdered or granular activated carbon. A granular media filter normally utilizes a bed of these materials to remove the contaminant.

by a single layer of pyrolytic carbon in the case of fertile parti cles.Each layer is around 40 µm thick. The buffer layer holding the fission products (especially gasses) consists of a thicker layer of porous pyrocarbon deposited directly on the kernel by CVD.The thickness of this layer is around 100 µm and its density is 50 % of the theoret

reaction product (or corrosion product layer). Active CenterIn chain growth polymerization, the highly reactive spot on the growing polymer chain where new monomer is added. The four most common types are a free radical (atom with an unpaired electron), carbanion (carbon centered negative ion), carbocation (carbon centered positive ion), or

an effective filter modification. The optimization of running filters with the BOKELA filter revamp program is a very economical alternative to new investments. With this revamping program inadequate performance, excessive maintenance and high operating costs of existing filters can be quickly and inexpensively eliminated.

Introduction. As syphilis is a notable clinical and pathological imitator, its diagnosis remains challenging. Physicians should be vigilant to suspect syphilis in cases of non specific signs, such as lymphadenopathies, even in patients with no apparent risk for sexually transmitted infections or a history of primary syphilis.
